The maintenance of Implant-supported Prosthesis is essential to the success of dental implants. Therefore, the aim of the study was to conduct a review the literature addressing maintenance Implant-Supported Prosthesis in order to guide planning for the longevity of oral rehabilitation. We conducted a detailed search strategy for the Pubmed / Medline Dentistry and Oral Science, used as descriptors: “Oral Hygiene“ and “Dental Implant until July, 2013. The results were grouped together in topics (Clinical Exam and Oral Hygiene) and discussed. Conclusion: A regular maintenance program for oral patient implantprosthesis is essential to the longevity of the treatment. Different methods and devices are effective for cleansing. However one orientation (in writing) must be offered to patients, since inadequate cleaning can create regions of abrasion on the surfaces of abutments and dental implants.

The purpose of current implantology is to ensure that implants maintain its state of full health, proper function and aesthetics. The aim of this paper is to discuss, through a literature review, the importance of keratinized mucosa in relation to cleaning, gingival maintenance, aesthetics involving dentistry implant and evaluating some options to provide a keratinized mucosa when it is insufficient. For the studies identification, it is included or considered in this review, Pubmed database with the following keywords: implant and mouth mucosa and, according to the criteria for inclusion and exclusion, 27 articles were selected. According to the reviewed articles, it was found that the keratinized tissue does not influence the survival of the implant, but it facilitates the cleaning, decreases the irritation of the peri-implant tissues and promotes aesthetics in anterior regions.

Apical surgeries are part of a segment of root canal treatment by which we can correct or eliminate iatrogenic deficiencies arising from conventional endodontic treatment. Currently no consensus among authors regarding to the factors linked to the surgery success as the execution of an apex resection followed by retropreparation and retrofilling. The apex resection performed 3mm from apical vertex allows the elimination of most apical ramifications, and it is a consensus part of the treatment. The preparation of cavities using ultrasonic tips has advantages over those made with drills such as better cleaning of the cavity, the possibility of lower cutting angle of the apical resection and deeper retropreparation. Another detail to consider is the type of tip, since the diamond tips in a more angulated inclination have higher cutting efficiency but causing increased formation of debris on the dentin walls. Finally, filling the cavity with an apical filling material allows proper sealing of the intracanal contents favoring apical healing.

In the practice of dental radiology, although there was no production of aerosols, there is the contamination of equipment and surfaces by contact with blood and saliva. This is making necessary the adoption infection control procedures to protect patients and staff. The objective of this paper is to present the procedures of prevention during the radiographic examination and radiographic processing in the darkroom. The proposed recommendations for the area of Dental Radiology include efficient cleaning and protection of equipment and surfaces, personal protective measures and to avoid contamination of the darkroom. These recommendations are obtained by simple procedures as cover films and radiological equipment with plastic barriers.

We know the importance of treating water for human consumption because changes in the physicochemical and / or biological has been associated with various health problems, the quality of water intended for human consumption must meet potability standards established by governmental decree 518/2004. The aim of this study was to evaluate the quality of water supplied schools and daycare in the city of São Carlos - SP. We selected 31 schools and kindergartens, and at intervals of 3 months, two water samples taken at three different points - network, tank and fi lter - totaling 186 samples, with an interval of three months, to verify possible differences in sampling points and at different times. The samples were evaluated for the following parameters: presence of total coliform and fecal coliform / E. coli count of heterotrophic bacteria, determination of pH, fl uoride, free residual chlorine, turbidity and color. The largest number of samples outside the standard for coliform was coming from the fi lters and the network, heterotrophic bacteria in most samples was taken out of standard fi lters. In the physical-chemical analysis of samples as many non-standard pH occurred in the network, network, and fl uoride in the fi lter pair in the fi lter to free chlorine and turbidity in the reservoir. The parameter with a larger sample size was inadequate fl uoride. We need more attention to the conservation, cleaning and maintenance of building reservoirs and fi lters in schools and kindergartens of San Carlos, since the water was considered unfi t for consumption.
