Association between oral health-related quality of life and atraumatic restorative treatment in school children: An exploratory study.

Background: The present study's objectives were to compare the perceptions of oral health-related quality of life (OHRQoL) among school children presents dental caries with that of caries-free school children, and to evaluate the subjective impact of atraumatic restorative treatment (ART) on the OHRQoL of school children. Design: Exploratory study. Setting: Public school in Piracicaba, Brazil. Materials and Methods: The sample was composed of 30 children in the age-group of 8-10 years. The children were divided into two groups: one with caries and other without caries. The information related to OHRQoL was obtained through the administration of the Child Perceptions Questionnaires (CPQ 8-10 ). To evaluate the impact of ART on the school children's OHRQoL, the CPQ 8-10 was re-administered 4 weeks after the initial treatment. For statistical analysis we used the nonparametric Wilcoxon test for two dependent variables (test and re-test groups) and the nonparametric Mann-Whitney test for independent variables (test and control groups). Results: It was observed that children with dental caries reported larger impact of oral health conditions on the quality of life when compared with the caries-free group, especially in the emotional and social well-being domains ( P≤.05). After the school children who presented with dental caries received ART, there was improvement in the median scores of CPQ 8-10 in all of the domains, but particularly in the functional limitation domain ( P≤.05). Conclusion: Dental caries exerts a strong influence on the OHRQoL of children. ART was shown to be a simple and painless caries management approach that could improve the OHRQoL of school children.

Trachoma among the Yanomami Indians

The Yanomami are one of the last primitive groups of Indians living in Brazil. They have almost no contact with other cultures. The epidemiology of eye disease among Yanomami is virtually unknown. For the first time, a trachoma survey was conducted among Yanomami Indians in the State of Amazonas near the Venezuelan border of the Brazilian rain forest. Ophthalmic examination was carried out on a total of 613 individuals (338 males and 275 females) from eight Yanomami villages along the Marauiá River located in the upper Rio Negro Basin. Age was classified into three categories (children, adults, and elderly) and trachoma was classified into five grades: follicular, inflammatory intense, cicatricial, trichiasis, and corneal opacity. Trachoma was endemic in all villages visited. Overall, 30.3 percent of the subjects had trachoma. Females were significantly more affected (37.4 percent) than males (23.9 percent). The inflammatory trachoma rate reached 24.9 percent in children and the cicatricial form increased with age, reaching 13.9 percent among adults and 35.21 percent among the elderly. Trichiasis or corneal opacities were not detected and treatment of the entire population was initiated with 1 g azithromycin. The detection of endemic trachoma among the Yanomami is relevant for the understanding of the epidemiology of this disease in the Brazilian rain forest and underscores the necessity for a program of trachoma control in this region
