摘要
目的:探讨乳前牙反与恒前牙反、磨牙关系及类骨面畸形的关系。方法:对102例口腔社区调查中诊断为乳前牙反的儿童,6年后进行追踪调查。以同期调查中无乳前牙反及恒前牙反的102名儿童作为对照,进行牙颌发育情况的检查。结果:乳前牙反组102例中,51例(50.0%)为恒前牙反。与个别乳前牙反组相比,多个相邻乳前牙反组演变为恒前牙反的危险度比值比为6.8(95%可信限2.7～17.6),达到统计学显著水平。且多个乳前牙反组类错及骨面畸形的罹患率均明显高于对照组及个别前牙反组。结论:多个乳前牙反,尤其是多个相邻乳前牙反应是临床矫治工作的重点。
Objective: To determine the relationship between anterior deciduous crossbite and anterior permanent crossbite, Angle classification of malocclusion and class Ⅲ jaw relationship through a follow up study in community children. Methods: A follow up study was done six years later in 102 children who were out of 120 children having anterior deciduous crossbite detected in a survey of six years before. Other 102 children with normal occlusion of deciduous and permanent teeth were treated as the control group. Results: There were 51 out of 102 cases developed anterior permanent crossbite. In comparison with the group with 1~2 anterior deciduous crossbite, the group with more than two neighboring anterior deciduous crossbite had more significant probability to turn into anterior permanent crossbite, OR=6.8 (95%CI: 2.7~17.6). The patients with more than 2 neighboring anterior deciduous teeth crossbite had significantly more chance of developing Angle Ⅲ malocclusion and class Ⅲ jaw relationship than those in the control group and those with 1~2 anterior deciduous teeth crossbite. Conclusion: Clinical orthodontists should pay more attention to the patients with more than 2 neighboring anterior deciduous crossbite.\;
