Malocclusion prevalence in the deciduous and permanent dentition of schoolchildren in the city of São Paulo, Brazil, 1996


, : Malocclusion prevalence in the deciduous and permanent dentition of schoolchildren in the city of São Paulo, Brazil, 1996. Cadernos de Saude Publica 18(5): 1197-1205

The purpose of this study was to estimate the prevalence of malocclusion in deciduous and permanent dentition of schoolchildren enrolled in public and private schools in the city of Sao Paulo, Brazil, in 1996. Occlusal conditions were classified as normal, mild, and moderate/severe according to World Health Organization criteria. The results refer to 985 schoolchildren ages five and 12 years. Prevalence of malocclusion was high, increasing from 48.97 +/- 4.53% in the deciduous dentition to 71.31 +/- 3.95% in the permanent dentition. The proportion of moderate/severe malocclusion was nearly twice as great in the second dentition (OR = 1.87; 95% CI = 1.43-2.45; p < 0.001). No significant difference was observed according to gender or public vs. private school. Statistically significant differences were associated with ethnicity, indicating the complexity and diversity of occlusion in the population and suggesting the need for longitudinal studies.

The design of beta-barrels has always been a formidable challenge for de novo protein design. For instance, a persistent problem is posed by the intrinsic tendency to associate given by free edges. From the opposite standpoint provided by the rede...

Compared with porcine kidney cells,...
