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.
本研究旨在评估1996年巴西圣保罗市公立和私立学校中小学生乳牙列和恒牙列错牙合畸形的患病率。根据世界卫生组织标准，咬合情况分为正常、轻度和中度/重度。研究结果涉及985名5岁和12岁的学童。错牙合畸形的患病率很高，从乳牙列的48.97 +/- 4.53%上升到恒牙列的71.31 +/- 3.95%。中度/重度错牙合畸形在恒牙列中的比例几乎是乳牙列的两倍（比值比=1.87；95%置信区间=1.43 - 2.45；p<0.001）。根据性别或公立与私立学校划分，未观察到显著差异。具有统计学意义的差异与种族有关，这表明该人群咬合情况的复杂性和多样性，并提示需要进行纵向研究。
