自锁托槽矫治器对慢性牙周炎正畸治疗患者牙周组织的影响

Effect of self-ligating bracket appliance on the periodontal tissues in patients with chronic periodontitis after orthodontic treatment

目的:探讨自锁托槽矫治器对慢性牙周炎正畸治疗患者牙周组织的影响。方法:选取我院收治的慢性牙周炎正畸治疗患者56例,根据治疗方案不同分为观察组及对照组,观察组采用自锁托槽矫治,对照组采用传统托槽矫治;观察并记录两组治疗前后牙周组织状况及牙齿松动度(TM),并检测两组治疗前后龈沟液中白介素(IL)-1β、肿瘤坏死因子(TNF)-α水平变化。结果:两组治疗后牙周探诊深度(PD)、附着丧失(CAL)、龈沟出血指数(SBI)及菌斑指数(PLI)与治疗前比较均明显降低,牙龈退缩指数(GR)则明显升高(P<0.05),观察组治疗后PD、CAL、SBI及PLI明显高于对照组,GR明显低于对照组(P<0.05);两组治疗后TM明显改善,其中0°牙齿数量增多,Ⅰ°~Ⅲ°牙齿数量减少(P<0.05);两组治疗后龈沟液中IL-1β、TNF-α水平均显著低于治疗前(P<0.05);观察组治疗后龈沟液中IL-1β、TNF-α水平明显低于对照组(P<0.05)。结论:自锁托槽矫治技术可有效改善慢性牙周炎患者牙周组织及牙齿松动状况,降低牙周周组织中炎症因子水平,疗效确切。

Objective：To explore the effect of self-ligating bracket appliance on the periodontal tissues in patients with chronic periodontitis after orthodontic treatment.Methods：A total of 56 patients with chronic periodontitis who were admitted in our hospital were included in the study and divided into the observation group and the control group according to different treatment protocols.The patients in the observation group were given self-ligating brackets,while the patients in the control group were given traditional brackets.The periodontal tissues and tooth motility（TM）before and after treatment in the two groups were observed and recorded.IL-1βand TNF-αlevels in the gingival crervicular fluid（GCF）before and after treatment inthe two groups were detected.Results：PD,CAL,SBI,and PLI after treatment in the two groups were significantly reduced,while GR was significantly elevated when compared with the control group（P〈0.05）.PD,CAL,SBI,and PLI after treatment in the observation group were significantly lower than those in the control group（P〈0.05）,while GR was significantly higher than that in the control group（P〈0.05）.TM after treatment in the two groups was significantly improved,among which the number of 0°TM was significantly increased,while the number ofⅠ°~ Ⅲ°TM was significantly reduced（P〈0.05）.IL-1βand TNF-αlevels in GCF after treatment in the two groups were significantly reduced when compared with before treatment（P〈0.05）.IL-1βand TNF-αlevels in GCF after treatment in the observation group were significantly lower than those in the control group（P〈0.05）.Conclusions：The self-ligating brackets can effectively improve the periodontal tissues and TM in patients with chronic periodontitis,and reduce the levels of inflammatory cytokines in periodontal tissues,with an accurate efficacy.
