Immediate “coping strategies” discussed during pre-test Alleviating symptoms counselling need to be reviewed cheap cialis soft 20mg on line, for example buy cialis soft 20mg without prescription, what Treatment should be directed towards individual does the patient have planned for the rest of the symptoms always taking into account possible side day, and who can they be with that evening? Early Trials conducted in Thailand during 1998 diagnosis and access to prompt, effective treatment demonstrated that the use of even a short course of opportunistic infections such as candidiasis, of Zidovudine was effective, providing greater herpes and tuberculosis is also important. This reduces transplacental transmission and considerable improvements have occurred in rates by up to 50%. Current knowledge recommends the single dose to the mother at the onset of labour use of combination therapy, using three or more and then to the baby within 72 hours of delivery, antiretrovirals. Anti-retroviral therapy is costly and significantly reduced the risk of transmission. This is therefore not readily available in all European study compared the safety and efficacy of short regions. Resistance to therapy is a real challenge infection at birth, 6–8 weeks and 14–16 weeks.

Partner Advocacy, education, and empowerment notification is voluntary in most European Advocacy is concerned with promoting the patient’s countries. Patients who are manager should normally be notified and there informed about their infection, including its should be a procedure in place for the management transmission and treatment can take greater control of such incidents. Important points to consider include: Communication • Most needle stick injuries are superficial and do Good communication skills are essential in all not involve the transfer of infected material or aspects of nursing care as they improve our blood. This should always be started • being aware of your own body language: are you as soon as possible – ideally immediately – giving relaxed and friendly signals if patients need although it may be effective even up to several days confidence to express their concerns? Goals should be realistic and reflect more expert help or a referral should be sought as the individual level of impairment and assistance soon as possible. The main principles of nursing It is one of the nurse’s and midwife’s responsibilities care should be to promote independence and assist to help prepare, advise, support and educate the the patient in meeting their individual needs. Rehabilitation Loss of self control and uncertainty regarding Rehabilitation and home care offers a number of health or employment can result in feelings of potential benefits: hopelessness and despair. Prevention strategies These should be integrated into existing systems such as health care, education and community based organizations. Viral hepatitis amount of infected blood passed into another is so-called because the principal cell the virus person may cause infection. Hepatitis B is a viral infection of the liver and is a Epidemiological summary major cause of morbidity and mortality worldwide. The main modes of transmission are: Manifestations • Sexual: through unprotected vaginal, anal and Incubation can be from 6 weeks to 6 months. Coinfection with hepatitis C fatigue, abdominal pain, flatulence and indigestion increases the risk of chronic active liver disease. In this 10%, blood Describe the main modes of tests reveal ongoing, viral replication 6 months after transmission of Hepatitis B. The risk of chronic infection is much greater for babies infected at birth and 90% of Diagnosis infected babies go on to become long term carriers. If immunoglobulin is not available, nature of the infection and how to minimise risk vaccination alone is usually effective. Family members and/or exposure or within 2 weeks of sexual or close sexual partners should also be informed. Health personal contact (family members, close personal care workers in attendance should be reminded of contacts and sexual contacts) should receive the need to employ universal precautions. This should be followed by hepatitis B vaccination if further Screening and contact tracing exposure is possible. Recent sexual partners should releasing virus particles which enter the blood be contacted where possible for counselling and stream.

Primary sources of organic nitrates include human sewage and livestock manure purchase 20mg cialis soft free shipping, especially from feedlots discount cialis soft 20mg without a prescription. Since they are very soluble and do not bind to soils, nitrates have a high potential to migrate to ground water. Because they do not evaporate, nitrates/nitrites are likely to remain in water until consumed by plants or other organisms. Short-term Excessive levels of nitrate in drinking water have caused serious illness and sometimes death. This can be an acute condition in which health deteriorates rapidly over a period of days. Nitrate levels greater than 5 mg/L indicate the possibility that agricultural chemicals may be reaching the water source, and pesticide testing is recommended. Nitrate specific resin should be used with anion exchange systems to prevent the possibility of a maladjusted or malfunctioning anion exchange system from increasing the nitrate level due to sulfate exchange. We recommend that persons shopping for nitrate removal systems shop carefully and purchase only from a dealer experienced in nitrate removal.

In general, the symptoms begin 1 to 2 days following infection with a virus that causes gastroenteritis and may last for 1 to 10 days, depending on which virus causes the illness. The term abiotic is also used to denote a process which is not facilitated by living organisms. The absorption spectrum is studied to evaluate the function of photosynthetic pigments. Because accessory pigments have different absorption optima than chlorophylls, presence of accessory pigments allows photosynthetic systems to absorb light more efficiently than would be possible otherwise. These compounds are not dangerous to health but can make the water unpleasant to drink. Carbon filtration comes in several forms, from small filters that attach to sink faucets to large 149 Bacteriological Diseases ©11/1/2017 (866) 557-1746 tanks that contain removable cartridges. Activated carbon filters require regular maintenance or they can become a health hazard. It is composed of an outer cortex, and a central medulla, each involved in different hormone: mediated phenomena. This technology uses an up-flow clarifier with low-density plastic bead media, usually held in place by a screen. This adsorption media is designed to enhance the sedimentation/clarification process by combining flocculation and sedimentation into one step. In this step, turbidity is reduced by adsorption of the coagulated and flocculated solids onto the adsorption media and onto the solids already adsorbed onto the media. Cleaning of this type of clarifier is initiated more often than filter backwashing because the clarifier removes more solids. As with the tube-settler type of package plant, the sedimentation/ clarification process is followed by mixed-media filtration and disinfection to complete the water treatment. Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a film of molecules or atoms (the adsorbate). It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. The term sorption encompasses both processes, while desorption is the reverse process. Adsorption is present in many natural physical, biological, and chemical systems, and is widely used in industrial applications such as activated charcoal, synthetic resins, and water purification. Adsorption, ion exchange, and chromatography are sorption processes in which certain adsorbates are selectively transferred from the fluid phase to the surface 150 Bacteriological Diseases ©11/1/2017 (866) 557-1746 of insoluble, rigid particles suspended in a vessel or packed in a column. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms, and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces) or chemisorption (characteristic of covalent bonding). They occur as single cells floating in water, or as multicellular plants like seaweed or strands of algae that attach to rocks. However, the acid neutralizing capacity refers to the combination of the solution and solids present (e. In the natural environment carbonate alkalinity tends to make up most of the total alkalinity due to the common occurrence and dissolution of carbonate rocks and presence of carbon dioxide in the atmosphere. Other common natural components that can contribute to alkalinity include borate, hydroxide, phosphate, silicate, nitrate, dissolved ammonia, the conjugate bases of some organic acids and sulfide. Solutions produced in a laboratory may contain a virtually limitless number of bases that contribute to alkalinity. Commercially, as in the pool industry, alkalinity might also be given in the unit ppm or parts per million. In humans, the allantois is involved in early blood formation and development of the urinary bladder. Structural variations between alleles may lead to different phenotypes for a given trait. This phenomenon is presumed to have been the mechanism whereby many species of organisms evolved. Binding of the appropriate molecule to the allosteric site changes the conformation of the active site, making it either more or less receptive to the substrate. Radioactive elements have atomic nuclei so heavy that the nucleus will break apart, or disintegrate spontaneously. Although radioactivity from refined radioactive elements can be dangerous, it is rare to find dangerous levels of radioactivity in natural waters. An alpha particle is a doubly-charged helium nucleus comprised of two protons, two neutrons, and no electrons. Alpha particles do not penetrate matter easily, and are stopped by a piece of paper. Beta particles are much more penetrating and can pass through a millimeter of lead.

Bacteria levels do not necessarily decrease as a watershed develops from rural to urban discount cialis soft 20mg free shipping. Farm animal manure and septic systems are replaced by domestic pets and leaking sanitary sewers cialis soft 20 mg cheap. In fact, stormwater runoff in urbanized areas has been found to be surprisingly high in fecal coliform bacteria concentrations. The presence of old, disintegrating storm and sanitary sewers, misplaced sewer pipes, and good breeding conditions are common explanations for the high levels measured. Coli, and Enterococcus bacteria are the "indicator" organisms generally measured to assess microbiological quality of water. Because it is so much more expensive and tedious to do so, actual pathogens are virtually never tested for. Over the course of a professional lifetime pouring over indicator tests, in a context where all standards are based on indicators, water workers tend to forget that the indicators are not the things we actually care about. They are of little concern at low levels, except to indicate the effectiveness of disinfection. At very high levels they indicate there is what amounts to a lot of compost in the water, which could easily include pathogens (Ten thousand general coliform bacteria will get you a beach closure, compared to two or four hundred fecal coliforms, or fifty enterococcus). They are another valuable indicator for determining the amount of fecal contamination of water. The more closely related the animal, the more likely pathogens excreted with their feces can infect us. Human feces are the biggest concern, because anything which infects one human could infect another. Keep in the back of your mind that the ratio of indicators to actual pathogens is not fixed. Whenever you are trying to form a mental map of reality based on water tests, you should include in the application of your water intuition an adjustment factor for your best guess of the ratio between indicators and actual pathogens. Foodborne Disease Significance of Escherichia coli 0157:H7 and other Entrohemorrhagic E. Impact of Changing Consumer Lifestyles on the Emergence /Reemergence of Foodborne Pathogens. Identification of Enteric Bacteria by Using Metabolic Characteristics: An Excerpt from a Bulletin Published by the Centers for Disease Control. The covert release of a biologic agent may not have an immediate impact because of the delay between exposure and illness onset, and outbreaks associated with intentional releases might closely resemble naturally occurring outbreaks. Indications of intentional release of a biologic agent include 1) an unusual temporal or geographic clustering of illness (e. Agents of highest concern are Bacillus anthracis (anthrax), Yersinia pestis (plague), variola major (smallpox), Clostridium botulinum toxin (botulism), Francisella tularensis (tularemia), filoviruses (Ebola hemorrhagic fever, Marburg hemorrhagic fever); and arenaviruses (Lassa [Lassa fever], Junin [Argentine hemorrhagic fever], and related viruses). Approximately 2--4 days after initial symptoms, sometimes after a brief period of improvement, respiratory failure and hemodynamic collapse ensue. Inhalational anthrax also might include thoracic edema and a widened mediastinum on chest radiograph. Gram-positive bacilli can grow on blood culture, usually 2--3 days after onset of illness. Cutaneous anthrax follows deposition of the organism onto the skin, occurring particularly on exposed areas of the hands, arms, or face. An area of local edema becomes a pruritic macule or papule, which enlarges and ulcerates after 1--2 days. A painless, depressed, black eschar, usually with surrounding local edema, subsequently develops. Plague Clinical features of pneumonic plague include fever, cough with muco-purulent sputum (gram-negative rods may be seen on gram stain), hemoptysis, and chest pain. Inhalational botulism would have a similar clinical presentation as foodborne botulism; however, the gastrointestinal symptoms that accompany foodborne botulism may be absent. Smallpox (variola) The acute clinical symptoms of smallpox resemble other acute viral illnesses, such as influenza, beginning with a 2--4 day nonspecific prodrome of fever and myalgias before rash onset. Several clinical features can help clinicians differentiate varicella (chickenpox) from smallpox. The rash of varicella is most prominent on the trunk and develops in successive groups of lesions over several days, resulting in lesions in various stages of development and resolution. In comparison, the vesicular/pustular rash of smallpox is typically most prominent on the face and extremities, and lesions develop at the same time. After an incubation period of usually 5--10 days (range: 2--19 days), illness is characterized by abrupt onset of fever, myalgia, and headache. Other signs and symptoms include nausea and vomiting, abdominal pain, diarrhea, chest pain, cough, and pharyngitis. A maculopapular rash, prominent on the trunk, develops in most patients approximately 5 days after onset of illness. Bleeding manifestations, such as petechiae, ecchymoses, and hemorrhages, occur as the disease progresses (8). The laboratory should attempt to characterize the organism, such as motility testing, inhibition by penicillin, absence of hemolysis on sheep blood agar, and further biochemical testing or species determination. An unusually high number of samples, particularly from the same biologic medium (e. In addition, central laboratories that receive clinical specimens from several sources should be alert to increases in demand or unusual requests for culturing (e. When a laboratory is unable to identify an organism in a clinical specimen, it should be sent to a laboratory where the agent can be characterized, such as the state public health laboratory or, in some large metropolitan areas, the local health department laboratory. Clinical laboratories should report any clusters or findings that could indicate intentional release of a biologic agent to their state and local health departments. After the terrorist attacks of September 11, state and local health departments initiated various activities to improve surveillance and response, ranging from enhancing communications (between state and local health departments and between public health agencies and health-care providers) to conducting special surveillance projects. These special projects have included active surveillance for changes in the number of hospital admissions, emergency department visits, and occurrence of specific syndromes. Activities in bioterrorism preparedness and emerging infections over the past few years have better positioned public health agencies to detect and respond to the intentional release of a biologic agent. Immediate review of these activities to identify the most useful and practical approaches will help refine syndrome surveillance efforts in various clinical situations. Update: investigation of anthrax associated with intentional exposure and interim public health guidelines, October 2001. Humans are infected by ingesting cysts, most often via food or water contaminated with human fecal material (view diagram of the life cycle). Entamoeba histolytica trophozoite Entamoeba histolytica immature cyst Entamoeba histolytica mature cyst 89 Bacteriological Diseases ©11/1/2017 (866) 557-1746 Entamoeba histolytica is an amoeboid protozoan parasite of the intestinal tract, and in some cases other visceral organs especially the liver. There are several species in this genus, distinguished by their number of nuclei in the cyst and position of the endosome, whether or not they form a cyst, and whether they invade tissues or remain in the intestinal lumen. Entamoeba histolytica has four nuclei in the cyst, a central endosome, forms a cyst, and can be a tissue invader. The amoeboid trophozoites can live in the intestinal crypts, feeding on intestinal contents and host tissue, and multiplying by fission. The dehydration of the feces causes the trophozoites to begin the process of encystment. Undigested food is discharged, and the trophozoite condenses and forms a spherical shape to form what is called the pre-cyst, and the cyst wall is secreted. Within the cyst there are two nuclear divisions resulting in 2 nuclei in the immature cyst and 4 nuclei within the mature cyst. When the cyst is ingested by another host the parasite excysts in the intestine and undergoes cytoplasmic division to produce 4 trophozoites. In some cases the trophozoites secrete proteolytic enzymes which destroy the intestinal epithelium allowing the trophozoiute to enter the host tissue. Extensive Tissue Destruction These can form large abscesses that may allow the parasite to enter the blood stream and be carried to the liver and other organs. In these extra-intestinal sites the trophozoites also can cause extensive tissue destruction. Trophoziotes in diarrheic feces are not stimulated to encyst because the feces are not dehydrating. Accurate diagnosis of this parasite is important to prevent unnecessary treatment of a non-pathogenic strain, and to ensure treating a pathogenic strain. Definitive diagnosis is based on morphological characteristics of the trophozoites and cysts, the presence of erythrocytes in the trophozoites, and clinical symptoms.

She had hexanedione and methyl butyl ketone buildup in her uterus sup- porting the intestinal fluke and its eggs in the uterus order cialis soft 20mg without a prescription. She was advised to stop eating cold cereals and commercial bev- erages and kill the parasites immediately purchase 20 mg cialis soft mastercard. In spite of repeatedly killing the flukes and bacteria with a frequency generator and making herculean efforts she was no better off eight months later. She had the intestinal fluke in her uterus (probable cause of cyst) and Schistosoma haematobium (bladder parasite) throughout her body. She was started on the parasite program and in one week her bladder pain was under control but bleeding (from the cyst in uterine wall) continued. Schistosomes are very contagious, probably even from toilet seats and the house dust of an infected person. Her bladder and uterus were both full of propyl alcohol, tooth metal, fluoride, cobalt, zirconium, aluminum, antimony, cadmium, and formaldehyde. She was delighted, though, to understand her problem and made the dental appointment. Contraception There is an excellent pamphlet available at health food 10 stores, called Wild Yam for Birth Control Without Fear that informs that 3 capsules taken two times a day provides reliable (perfect) contraception provided you give it a two month head start. The Silent Cervix The cervix is a big “trouble spot” for women just as the prostate is for men. Sometimes a brief needle-like pain does alert you to something going on there, but it is easy to miss. The cervix is constantly secreting a little bit of mucous and this helps it stay clean but why give it mercury and copper and gold to secrete? Many a fertility problem has been solved by stopping the toxic pollution of uterus, ovaries, and cervix. Kill parasites and bacteria regularly, every week, with the herbal recipe or by zapping. During your fertile years, you were meant to have a peak of 100 picograms/milliliter (pg. Progesterone, on the other hand, only peaks once, on day 22, and it should reach a level 20 to 100 times as high as estrogen! Kill all the parasites, bacteria and viruses, especially Gardnerella, Proteus, Chlamy- dia, Campylobacter, Neisseria, Treponema, Salmonella. This makes good sense, because the adrenal glands sit right on the kidneys and would be geographically close to the kidney bacteria. To avoid getting them back, do a kidney cleanse (page 549) to remove all crystals where they might hide. Start drinking two pints of water between meals plus water and milk (sterilized) at mealtime. Be- sides giving you a better hormone supply, your newly revitalized adrenals will get you through stress in better shape and keep your blood pressure normal. If you wish to get pregnant, clean up your body first, being very careful to prevent pregnancy during this time. Since every cleanup job increases your fertility, it is best to get the mercury, thallium, copper and nickel out of your body before your risk of conception is raised further by making other improvements. Two months later she was feeling much better and had all metal removed but was experiencing a slight return of symptoms which panicked her. Four weeks later she described how she had gotten immediate emotional relief after two cavitations were done. Our solvent test showed methyl butyl ketone, benzene and carbon tetrachloride (which we found in her Mountain Valley Arkansas Spring Water). She was so happy to find the cause of her problems and yet so angry at the nature of the cause that she planned to write to the water company. She also got a severe sugar craving and minor depression and headache with her period. She also had hookworms, pinworms, human liver fluke and cat liver flukes infesting her. She had all the metal from her fillings replaced and killed parasites with the herbal recipe. She resumed it and began kidney and liver cleanses to get longer lasting benefits. Then she cleaned her liver and after three cleanses (she got over 1,000 stones the first time! Terri Entzminger, age 16, had a long list of health problems including painful ovaries and painful periods for which she was put on birth control pills by her doctor. A parasite test showed intestinal fluke adults in the uterus, not in the intestine or liver. Six weeks later her periods were “great”, she did not need the pill and she was keeping the whole household on a maintenance program killing parasites. She killed them all with a frequency generator and decided to be more vigilant over parasites as long as she was such an ardent animal lover. She had done a liver cleanse by then and got a commode-full of stones (about 1,000), she had changed her plumbing, got rid of the water softener, killed parasites and cleansed her kidneys. She still had sinus problems and some arthritis and was planning dental metal replacement and cavitation cleaning to clear them up too. Infertility An ominous sign in any species, infertility is not just an- other disease or “problem. They can not run away, time is limited, and obviously ad- aptation is not occurring. Can we relax with the assurance that our intelligence, through the arm of science, will always rescue us? Are test tube fertilizations, fertility drugs, Cesarean sections, incubators for premature babies all triumphs for science? When the concern is overpopulation of this planet, repro- ductive failure might seem less ominous. Maybe only those who can survive parasitism, pollution and immune deficiency should survive in order to strengthen the species. The solution to our reproductive failure is not to find ever more artificial ways to conceive, to give birth, and to care for damaged babies. If you are unable to conceive or to provide viable sperms use an intelligent approach. The obstacles are parasites and pollutants, the same enemies of health we have seen before. Kill all large and small parasites with a zapper and the herbal parasite killing program. Remember to kill bacteria and viruses too, especially Gardnerella, Neisseria, Treponema, the ancient enemies of hu- man reproduction. The herbal way of killing parasites has been used by pregnant women without bad effects but this is not enough safeguard. Part two of regaining your reproductive freedom to have a child is removing pollutants. Gold, silver, copper and mercury can accumulate in the reproductive organs, wrecking the delicate hormone balance between estrogen and progesterone, or wrecking the motility of sperm. Research has not been done to search for dental metal in the uterus, ovaries and testicle of in- fertile couples. Remove all dental metal from your mouth, and replace it with metal-free composite. It is a serious hazard to conceive a child while mercury is loose and rampant in your body from the removal process. You may have tried fertility pills, in vitro fertilization, and other methods for getting pregnant over a ten year time period, all to no avail. Then you start cleaning up your body and taking your mercury out and suddenly you are pregnant before the job is complete! It may seem unreasonable and illogical to have to be careful after ten years of no worries, but play it safe. If you fail to observe this warning and do get pregnant too soon, you may pray for miscarriage.

cialis soft 20mg without a prescription

The authors concluded: “ Although a complete cleaning of the implant surfaces was not possible in any of the defect models generic 20mg cialis soft fast delivery, it was possible to clean the biggest part of the surface up to more than 95% in easy accessible defects cheap cialis soft 20mg fast delivery. In broad defects of 60° and 90° defect angulations, it was even possible to get access to more than 75% of the lower faces of the implant threads”. Narrow defects (< 30o) and the area under the threads were diffcult to reach (Sarhmann et al. In a subsequent study using the same model, the air-abrasive device was compared with other modalities as a stainless-steal curette and an ul- trasonic device with metal tip. In wide defects, the differences between the in- struments were more pronounced (Sahrmann et al. The two-abovementioned studies simulated condition similar to an open-fap debridement. Recently, the same research group 2 published another study using a bone defect-model that includes a custom-made mucosa mask in order to simulate the conditions of nonsurgical implant surface debridement, which 3 made the access to the implant even more diffcult. The air abrasive with a glycine powder and a subgingival nozzle provided superior cleaning results compared to a metal curette or an ultrasonic device with a metal tip. Again the differences between the instruments were 4 more pronounced in the wider defects irrespective of the operator’s experience (Ronay et al. Air pressure seems to be the most important parameter that infuences the cleaning 5 effciency of the air abrasive device. It has been shown that in order to get the best results when used subgingivally the device should be used with high pressure, deep insertion of 6 the nozzle and enough water fow. The cleaning effect of the device reaches deeper than the nozzle physically reaches and the movement of the nozzle improves the cleaning effciency, irrespective of the direction of the movement (Tastepe et al. The plaque extracts had a greater effect in decreasing the growth rate of fbroblasts than that of epithelial cells. The elemental composition of unused commercially pure titanium foils was 9% titanium (Ti), 48% carbon (C), 40% oxygen (O) and traces of 10% nitrogen (N) and chlorine, whereas intraorally contaminated foils exhibited 70% C, 20% O, 10% N and only traces of titanium (<1%). Next to bacterial contamination, treatment modalities used to decontaminate the titanium surface can also affect its surface topography and chemical composition. The surface composition of failed and retrieved ma- chined titanium implants after various cleaning procedures has been evaluated in a study. Although some of the tested methods resulted in a macroscopically clean surface, all of them failed to re-establish the original surface elemental composition (Mouhyi et al. In ad- dition, residues of the instruments may deposit themselves to the treated surfaces, which in turn might disturb cell attachment (Schwarz et al. Residues of various curettes and 226 Summary, Discussion… inserts for ultrasonic devices, as well as powder remnants after the use of air abrasive de- 1 vices, have been found on the titanium surfaces after instrumentation (Schwarz et al. It is obvious that an instrument would be of no value if it renders the surface non-biocompatible, i. Subse- 3 quently a third systematic review was conducted in chapter 4 and concluded that all instru- ments reduce the biocompatibility of the surface irrespective of the presence or absence of 4 plaque. The 7 air abrasive device showed slightly better results that the other modalities. This modality induced titanium alloy purity and hydrophily without altering osteoblast proliferation and 8 production of cytokines potentials (Toma et al. Similarly, an earlier animal study employing the ligature-induced peri-implantitis defect model demonstrated the cre- ation of a smooth surface, which supported a close adhesion of the sub-epithelial connective tissue (Schwarz et al. Taking together the results of the systematic reviews in chapters 2, 3, 4 it seems, based on the currently available in vitro data, that air-abrasive devices represent the most promis- ing tool in the treatment of peri-implant infections. They are effective in bioflm removal, without causing major changes on the surface topography or having detrimental effect on the biocompatibility of a titanium surface. These results are corroborated to a certain extent by fndings from animal studies. Mechanical cleaning with an air abrasive device appeared to provide adequate decontamination to allow for some new bone formation in direct contact with the implant surface (Roos-Jansåker et al. The available data suggest that air polishing used as an adjunctive mea- sure or as monotherapy can result in signifcant clinical improvements in terms of bleed- 3 ing scores, following a single or repeated nonsurgical treatment of peri-implant mucositis and/or peri-implantitis. At mucositis sites, glycine air polishing seems to be as effective as conventional mechanical debridement with non-metal instruments with or without local 4 antiseptics. For the non-surgical treatment of peri-implantitis, glycine powder air polishing was associated with a signifcant improvement in bleeding scores over the control mea- 5 sures investigated (Schwarz et al. A retrospective study evaluating the effect of an air abrasive device during surgical treatment of peri-implantitis compared with plastic curettes 6 and cotton pellets impregnated with saline reported that, although both groups revealed a signifcant improvement in clinical parameters, the air abrasive group yielded better results regarding bleeding scores and probing depths at 12 months (Toma et al. It has been shown that tricalcium phosphate, when used as an additive to powders, may increase the cleaning effciency of the air abrasive (Tastepe et al. However, all powders that were tested affected the biocompatibility and the extent to which this was infuenced depended on the powder used. This fnding has been attributed to the hard- ness and bigger particle size of sodium bicarbonate, which has also been observed to induce surface changes. It was speculated that a certain amount of surface ablation might improve the biocompatibility of moderate rough surfaces (Schwarz et al. In the study in 2 chapter 5, the aim was therefore to assess the possible effect of fve commercially available air-abrasive powders, on the viability and cell density of three types of cells: epithelial cells, gingival fbroblasts and periodontal ligament fbroblasts. This study showed that powders 3 might indeed have different effects on various cells. It has been speculated that tricalcium phosphate residues on 4 the implant surface could improve biocompatibility and support wound healing (Tastepe et al. Chemotherapeutica 6 Surface decontamination Chemotherapeutic agents, alone or in combination with mechanical instruments, have also 7 been used for cleaning implant surfaces. Chapter 6 reviewed the literature for evidence re- garding the ability of different chemotherapeutic agents to decontaminate titanium sur- faces. Yet, it seems 8 that citric acid has the highest potential to remove bacteria and bacterial products from titanium surfaces. It should however be kept in mind that chemical agents are less capable in 9 removing bioflm than mechanical instruments. In an earlier study different results with respect to the killing potential of citric acid were reported. In this study the antibacte- rial effcacy of several antimicrobials on the oral microfora attached to titanium specimens …& Conclusions 229 1 with a machined surface after overnight contamination in the oral cavity of volunteers was assessed. All agents used were shown to signifcantly reduce the total number of attached bacteria after immersion for 1 minute. However, citric acid showed less bactericidal effect 2 compared to the other agents. It was concluded that the antiseptics sodium hypochlorite, hydrogen peroxide, citric acid, chlorhexidine, and essential oils might have some benefcial 3 effect in reducing the bacteria load on titanium surfaces (Gosau et al. Surface biocompatibility 4 Chemotherapeutic agents may have an effect on the elemental composition of the titanium surface, which subsequently may affect the biocompatibility of the surface and the biologic 5 responses. Elemental contaminants or salts have been found on titanium surfaces after treat- ment with chemical agents (Mouhyi et al. An in vitro study as- 6 sessed the effect of different chemical agents (citric acid, hydrogen peroxide, chlorhexidine, tetracycline, doxycycline, sodium fuoride and peroxyacetic acid) on the oxide layer morphol- ogy of titanium. The treatments consisted of immersion of samples in a solution or rubbing 7 them on with cotton swabs. Rubbing with swabs led to signs of titanium oxide damage in a pH-related manner (Wheelis et al. Treatment 9 with citric acid and hydrogen peroxide resulted in respectively similar or enhanced prolif- eration of epithelial cells compared to an untreated control. Less favourable results were observed with chlorhexidine due to adsorption on the titanium surface (Ugvári et al. It is also reported that chlorhexidine signifcantly impaired the proliferation of osteoblasts on treated titanium surfaces. Based on these fndings the use of chlorhexidine is not recom- mended because it produces cytotoxic effects and may thus compromise the biocompatibil- ity of the surface (Kotsakis et al. A clinical study demonstrated that the application of a 35% phosphoric etching gel at pH 1 adjunctive to the use of carbon curette and rubber cup resulted at 5 months in a higher reduction in gingival index scores and a lower number of colony-forming units compared to control treatment (Strooker et al. In patients with peri-implant mucositis, profession- ally administered chlorhexidine (irrigation, gel application or combination of both) failed to show adjunctive benefcial effects compared with mechanical debridement alone (Porras et al. Similarly, in the surgical treatment of peri-implantitis 230 Summary, Discussion… chlorhexidine resulted to a greater suppression of anaerobic bacteria in short term but failed 1 to show superior clinical results compared to placebo-control (De Waal et al. In the study in chapter 7, the 3 available evidence with respect to the patient-administered measures for mechanical plaque removal around implant-supported restorations was scrutinized.
