| 目的：1、了解湖南益阳市区儿童的正畸治疗需要情况；以指导正畸临床治疗和卫生宣教工作；同时,也为公共卫生部门更合理有效地安排正畸相关医疗资源提供参考。方法：对158名符合纳入标准的7-9岁儿童进行模型制备、正牙合像拍摄。根据正畸治疗需要指数(IOTN)中的关于牙齿健康部分(DHC)的相关指数及关于美观部分(AC)相关指数,评价错牙合畸形在7-9岁儿童客观正畸治疗需要。结果：(1)7-9岁湖南益阳籍儿童,从DHC的结果表明有33%的儿童明确需要正畸治疗,53.7%的儿童没有或轻度需要正畸治疗；而从AC得分来看,有13.3%儿童有正畸需要,63.3%的儿童没有或轻度需要正畸治疗。(2)DHC与AC相关性结果分析表明二者有着显著相关关系。结论：7-9岁湖南益阳市区儿童中,有33%的儿童有客观正畸需要；但从美观部分(AC)相关指数来看要低于DHC；应加大早期矫治宣传力度。 |
