青少年口腔正畸患者正畸疗效的影响因素分析

目的 探讨青少年口腔正畸患者正畸疗效的影响因素。方法 选取2019年1月—2021年2月平顶山学院附属口腔医院收治的93例口腔正畸患者,依据正畸治疗标准（PAR）指数评定正畸疗效。口腔正畸结束满2年时PAR指数比口腔正畸结束时减少超过5为疗效不佳（作为复发组）,否则为未复发组。分析影响青少年口腔正畸患者正畸疗效的因素。结果 93例青少年口腔正畸患者中,复发19例,其余74例未出现复发。复发组Ⅰ类错畸形占比、早期矫治占比、保持器佩戴时间均低于未复发组（P <0.05）,复发组使用霍利保持器占比、保持器停用时间均高于未复发组（P <0.05）。多因素逐步Logistic回归分析结果显示,错畸形类型［O^R=4.874（95% CI：2.006,11.846）］、保持器类型［O^R=4.208（95% CI：1.731,10.227）］、保持器佩戴时间［O^R=4.522（95% CI：1.861,10.991）］是影响青少年口腔正畸患者正畸疗效的危险因素（P <0.05）。结论 错畸形类型、保持器类型、保持器佩戴时间与青少年口腔正畸患者正畸疗效有关。牙合牙合牙合

Analysis of factors affecting the efficacy of orthodontic treatment among adolescents

Objective To explore the factors affecting the efficacy of orthodontic treatment among adolescents.Methods We selected 93 patients undergoing orthodontic treatment in Pingdingshan College Affiliated Stomatological Hospital from January 2019 to February 2021. The efficacy of the orthodontic treatment was evaluated based on the Peer Assessment Rating (PAR) index. A decrease of the PAR index > 5 after 2 years of the orthodontic treatment compared to that at the end of the orthodontic treatment was regarded as poor efficacy (recorded as the recurrence group), and otherwise as the non-recurrence group. Factors that affected the efficacy of orthodontic treatment among the adolescent patients were analyzed.Results Among the 93 adolescent patients, 19 experienced recurrence, and the remaining 74 did not experience any recurrence. The proportions of class I malocclusion and early correction were lower, and the duration of retainer wearing was shorter in the recurrence group than in the non-recurrence group (P < 0.05), while the proportion of Hawley retainer use was higher and the duration of not wearing the retainer was longer in the recurrence group than in the non-recurrence group (P < 0.05). Multivariable Logistic regression analysis revealed that the type of malocclusion [O^R = 4.874 (95% CI: 2.006, 11.846) ], the type of retainer [O^R = 4.208 (95% CI: 1.731, 10.227) ], and the duration of retainer wearing [O^R = 4.522 (95% CI: 1.861, 10.991) ] were factors that affected the efficacy of orthodontic treatment among adolescent patients (P < 0.05).Conclusions The type of malocclusion, the type of retainer and the duration of retainer wearing are related to the efficacy of orthodontic treatment among adolescent patients.
