目的
记录、确定和讨论印度Bagalkot市4- 6岁儿童乳牙列咬合特征总体患病率的性别影响。
材料和方法
共有1000名4至6岁的儿童（583名男孩和417名女孩）进行了临床评估，包括乳磨牙，乳犬齿，发育间隙，覆盖和覆牙合，拥挤，前或后反牙合，中线差异，侧貌的测量，以及评估唇功能不全的存在。采用分层整群随机抽样的方法收集代表性样本。
结果
男性和女性之间的高度显着差异，观察到流行的平齐终端平面磨牙关系，I类和II类犬齿关系，覆盖和覆牙合0至2毫米，并为凸和直的轮廓。近中台阶和不对称磨牙关系的发生、发育间隙和灵长类间隙的存在、上颌牙中线移位、单牙前牙反牙合和双牙后牙反牙合的存在、2 ~ 4 mm的覆盖和凸面轮廓的存在有显著差异。
结论
结果显示，大部分儿童有错牙合畸形，且男女咬合特征有显著差异。这突出了识别出于牙齿健康或美学原因需要正畸治疗的儿童的重要性。研究还表明，大部分的咬合特征的患病率与其他社区，但在某些特征的患病率存在显着差异。
PURPOSE
To record, determine and discuss the gender influence on the overall prevalence of occlusal characteristics of primary dentition of 4- to 6-year-old children of Bagalkot City, India.
MATERIALS AND METHODS
A total of 1000 children (583 boys and 417 girls) 4 to 6 years old were evaluated clinically for primary molars, primary canines, developmental spaces, measurements of overjet and overbite, crowding, anterior or posterior cross bite, midline discrepancies, lateral profile, as well as assessment of the presence of lip incompetency. A stratified cluster random sampling procedure was executed to collect the representative sample.
RESULTS
Highly significant differences between males and females were observed for the prevalence of flush terminal plane molar relationship, class I and II canine relationship, overjet and overbite of 0 to 2 mm, and for both convex and straight profile. A significant difference was seen for the occurrence of mesial step and asymmetric molar relationship, presence of developmental and primate spaces, shift in maxillary dental midline, presence of both single tooth anterior and bilateral posterior cross bite, overjet of 2 to 4 mm and convex profile.
CONCLUSIONS
The data revealed that most of the children had a malocclusion and that there was a significant difference between male and female occlusal characteristics. This highlights the importance of identifying children who are in need of orthodontic treatment for dental health or aesthetic reasons. The study also indicated that the prevalence of most of the occlusal characteristics were comparable with other communities, but there existed substantial differences in prevalence of some traits.
