To determine the prevalence of malocclusion in the Mewat district of Haryana.
A cross-sectional study was conducted in government/private schools of Mewat district. A total of 3,042 subjects were selected, age ranging from 11-18 years. Parameters studied were molar relationship, facial profile, overjet, overbite, reverse overjet, open bite, and supernumerary teeth. The Chi-square test was used for calculating the -value.
The prevalence of normal occlusion was seen in 77.4%, Angle's class I malocclusion was present in 13.5%, class II in 7.7%, and class III was seen in 2.8% of the study population which is statistically significant. Straight facial profile was observed in 91%, 7.9% had convex and 1.08% had a concave profile. Increased overjet was present in 33.5% of cases and reverse overjet was seen in 1.08%. The normal overbite was recorded in 70%, increased bite was seen in 29% and the open bite was present in 0.95% of the examined population, supernumerary teeth were seen in 18 children.
There is a high prevalence of normal occlusion in the Mewati population. The results may provide baseline data for research and planning orthodontic services.

确定哈里亚纳邦梅瓦特地区错牙合畸形的患病率。
在梅瓦特地区的政府/私立学校进行了一项横断面研究。共选取3042名受试者,年龄在11至18岁之间。研究的参数包括磨牙关系、面部轮廓、覆盖、覆牙合、反覆盖、开牙合和多生牙。采用卡方检验计算P值。
77.4%的研究人群表现为正常牙合,13.5%为安氏I类错牙合,7.7%为II类,2.8%为III类,具有统计学意义。91%的人面部轮廓挺直,7.9%的人面部轮廓凸出,1.08%的人面部轮廓凹陷。33.5%的病例存在覆盖增加,1.08%存在反覆盖。70%的人覆牙合正常,29%的人覆牙合增加,0.95%的受检人群存在开牙合,18名儿童有多生牙。
梅瓦蒂人群中正常牙合的患病率较高。该结果可为正畸服务的研究和规划提供基线数据。
