Avaliação in vitro da atividade antimicrobiana de enxaguatórios bucais / In vitro evaluation of antimicrobial activity of mouthrinses

O potencial antimicrobiano dos seguintes enxaguatórios bucais: Periogard®, Plax®, Oral-B®, Flogoral ® e Listerine® foram avaliados in vitro, frente às seguintes cepas: Pseudomonas aeroginosa, Escherichiacoli, Cândida albicans, Staphilococcus áureos, Staphilococcus epidermidi e Enterococcus faecallis, por meio do método de difusão em Agar Muller Hinton, o qual foi distribuído em alíquotas de 25 ml, em placas de Pétri estéreis. Cinco discos de papel filtro foram colocados em pontos equidistantes e foram embebidos com 20 μl dos enxaguatórios testados. As leituras dos halos foram realizadas após 48 horas. Os melhores resultados médios foram obtidos pelo Periogard® e pelo Plax®.

Dental caries profile in Monte Negro, Amazonian state of Rondônia, Brazil, in 2008

OBJECTIVE: This epidemiological survey assessed the dental caries profile in Monte Negro, a small town in the Amazonian state of Rondônia, Brazil, and its relationship with the northern region, national and global goals for oral health in the years 2000 and 2020. MATERIAL AND METHODS: The groups randomly examined were composed of individuals aged 5, 12, 15 to 19, 35 to 44, 65 to 74 years, living in both rural and urban areas. RESULTS: The means dft (standard deviation) and DMFT (standard deviation) for the groups were, respectively, 3.15 (3.12), 3.41 (2.69), 5.96 (4.19), 16.00 (7.30) and 25.96 (9.82). Caries-free individuals were 34.42 percent, 14.81 percent and 8.16 percent in the preschoolchildren, schoolchildren and adolescent groups, respectively. The Significant Caries Index percentages applied to the two younger groups were 6.65 and 6.70, and they increased to 32.00 in the individuals aged 65 to 74 years. Care Index percentages for adolescents, adults and elderly groups were, respectively, 29.40, 25.00 and 1.41. The dental caries profile in Monte Negro in 2008 shows that, 8 years after the year 2000, no FDI/WHO goal for any age settled in 1982 has been achieved. Dental caries increased with age and the main dental problem of adult and elderly groups was tooth loss. CONCLUSION: Oral health promotion and prevention of oral disease policies are urgent needs. Setting of oral health goals and targets to people living in Monte Negro or Amazonia to be pursuit and achieved in a near future is an important action to do because of the culture, sanitary conditions and socioeconomic aspects of this particular population.

Dental caries experience in preschool children of Bauru, SP, Brazil

Aim: The main purpose of this study was to evaluate dental caries experience and prevalence in three to six-year old preschool children from three public kindergartens of the city of Bauru, SP, Brazil. Methods: The sample comprised 283 children (142 boys; 141 girls) aged 3 to 6 years old. For data analysis, the dmft (decayed, missing and filled teeth), Significant Caries Index (SiC Index), percentage of caries-free children, Gini Coefficient and Care Index were determined. Mann-Whitney and Kruskal-Wallis tests were used with 5% significance. Results: The mean (SD) dmft index was 1.40 (2.63). Among the examined children, 63.25% were caries-free. The decayed component comprised 77.28% of the dmft. The Care Index was 19.70%, indicating limited utilization of dental treatment by children. The SiC index was 4.11 and the Gini Coefficient was 0.78 in the survey. The results showed that there were no statistically significant differences in the prevalence of the disease between the ages and between males and females. Conclusions: Dental caries experience and prevalence in preschool children were considered low in this study and the occurrence of polarization of the disease was identified.
