Practical initiatives, such as free lectures and workshops, must be taken to broaden the knowledge of DEN and DS about BP and thus contribute to the prevention of BRONJ.
Water used on dental equipment can represent a source of infections It was assessed the quality of water in dental offices in 14 healthcare facilities of a Brazilian town. It was harvested samples to analysis in different locations: water reservoir, tap, dental unit water tank and three-way syringe. The samples were evaluated under methodologies for microbial (identification of total coliforms and thermotolerants coliforms; heterotrophic bacteria counting), chemical (free residual chlorine content) and physical (turbidity) analysis. None of the sample showed thermotolerants coliforms, however, total coliforms were identified in one tap and two tanks. Considering the percentage of healthcare facilities under study, the heterotrophic plate count indicated unaccepted values in the tap (0.07%), dental unit tank (100%) and three-way syringe (92%), disclosing a significant statistical difference (p< 0,001 -F-Test -ANOVA -Bonferroni comparisons). The percentages of chlorine on the samples were adequate in only 15% of tanks of the dental units. The turbidity presented inadequate standards in 1 tap and in 1 tank from three different facilities. It was observed that none of the healthcare facilities presented water to be considered adequate, according to the standard of the Ministry of Health, a worrying fact that may bring consequences to the health of the population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
