摘要:
[摘要]目的：采用自锁托槽矫治器对儿童牙颌畸形进行矫正，观察矫正效果及对美观度的影响。方法：选取笔者医院牙颌畸
形儿童90例进行研究，随机将患儿分为对照组和研究组，每组45例，对照组患儿采用传统托槽矫治器治疗，研究组则采用
自锁托槽矫治器。比较两组患儿临床疗效、牙周指数、疼痛评分、美观效果及炎症因子水平。结果：治疗后，研究组有效率
显著高于对照组（P ＜0.05）；两组患儿菌斑指数（PLI）、牙龈指数（GI）及龈沟出血指数（SBI）显著降低（P ＜0.05），
牙龈退缩指数（GR）显著升高（P ＜0.05），且研究组升高或降低幅度明显大于对照组（P ＜0.05）；研究组患者治疗
1d、1周后的疼痛评分显著低于对照组（P ＜0.05）；研究组美观效果显著高于对照组（P ＜0.05）；两组患儿肿瘤坏死
因子-α（TNF-α）、血管内皮生长因子（VEGF）、肾上腺皮质素释放因子（CRF）、前列腺素E2（PGE2）的水平均显著降低
（P ＜0.05），且研究组显著低于对照组（P ＜0.05）。结论：应用自锁托槽矫治器矫治儿童牙颌畸形疗效显著，可明显改善
牙周指数、疼痛情况和美观效果，减少炎症和应激反应，安全舒适，值得临川推广应用。
Abstract:

Abstract: Objective To correct the dental malformation in children by self-ligation bracket appliance, and to observe the
correction effects and its influence on the aesthetics. Methods Ninety children patients with dental malformation in our
hospital were enrolled in the study. The children patients were randomly divided into control group and study group, with 45
cases in each group. Control group was treated with conventional bracket appliance, and study group was given self-ligation
bracket appliance. The clinical effi cacy, periodontal index, pain score, aesthetic effect and infl ammatory factors levels were
compared between the two groups. Results After treatment, the effective rate of treatment in study group was signifi cantly
higher than that in control group (P ＜0.05). The plaque index (PLI), gingival index (GI) and sulcus bleeding index (SBI) were
signifi cantly decreased in the two groups (P ＜0.05)while the gingival recession index (GR) was signifi cantly increased (P ＜0.05),
and the increase or decreases in study group were signifi cantly greater than those in control group (P ＜0.05). The pain score
in study group at 1d and 1 week was signifi cantly lower than that in control group (P ＜0.05). The aesthetic effects in study
group were signifi cantly higher than those in control group (P ＜0.05).The levels of tumor necrosis factor-α (TNF-α), vascular
endothelial growth factor (VEGF),corticoid releasing factor (CRF) and prostaglandin E2 (PGE2) were signifi cantly decreased
in the two groups (P ＜0.05), and the levels in study group were significantly lower than those in control group (P ＜0.05).
Conclusion Self-ligation bracket appliance has signifi cant effi cacy in the treatment of dental malformations in children. And it
can signifi cantly improve the periodontal indexes, pain and aesthetic effects, reduce infl ammation and stress response, and it is
safe and comfortable and worth promoting.
