There are relatively few systematic studies, documenting the prevalence of mucosal disorders in children and adolescents. The purpose of this study was to determine the prevalence of oral lesions in 12- to 15-year olds living in Tehran and to assess the possible relationship between the occurrence of these lesions and gender.
A cross-sectional study was designed in which 1020 adolescents were participated. The sample size was based upon an expected oral lesion prevalence of 25%, a precision of 0.05 and a confidence level of 99. Epi-info version 6.0 was used for statistical analysis.
Two hundred eighty-six adolescents (28.0%) were diagnosed with at least one oral mucosal lesion at the time of the examination. The prevalence of any oral mucosal lesion was 29.2% among the boys and 26.9% among the girls. With the exception of melanotic macules, there were no statistically significant differences in oral mucosal lesion prevalence by gender.
More than 28% of the adolescents were found to have at least one oral mucosal lesion. Melanotic macule was found to be proportionally more common in boys than girls.
关于儿童和青少年黏膜疾病的流行情况，系统性研究相对较少。本研究旨在确定居住在德黑兰的 12 至 15 岁儿童中口腔病变的流行情况，并评估这些病变的发生与性别之间的可能关系。
设计了一项横断面研究，共纳入 1020 名青少年。根据预期的口腔病变流行率为 25%、精度为 0.05 和置信水平为 99%来确定样本量。采用 Epi-info 版本 6.0 进行统计分析。
在检查时，286 名青少年（28.0%）被诊断出至少有一种口腔黏膜病变。男孩中任何口腔黏膜病变的患病率为 29.2%，女孩中为 26.9%。除了黑色素斑以外，口腔黏膜病变的患病率在性别之间无统计学差异。
超过 28%的青少年被发现至少有一种口腔黏膜病变。黑色素斑在男孩中比女孩中更为常见。
