自锁托槽矫治器治疗牙周病患者的效果

Effect of Self-locking Bracket Appliance on Periodontal Patients

目的应用自锁托槽矫治器治疗牙周病患者的效果。方法回顾性纳入郑州大学第一附属医院2018年6月至2021年2月收治的应用传统托槽矫正器治疗的42例牙周病患者作为对照组,纳入同期应用自锁托槽矫治器治疗的84例牙周病患者作观察组,均随访至矫治完成。比较两组矫治前、矫治完成后咀嚼效能,矫治完成后正畸效果,矫治前、矫治8周后龈沟液炎症因子、牙周指数情况。结果与矫治前比较,两组矫治完成后咀嚼效能均降低,且观察组低于对照组(P<0.05);矫治完成后,对照组临床正畸总有效率(76.19%)低于观察组(96.43%)(P<0.05)。两组矫治8周后龈沟液肿瘤坏死因子-α、C反应蛋白水平、牙菌斑指数、龈沟出血指数、牙龈指数相比矫治前升高,但观察组低于对照组;两组龈沟液β-防御素2水平均升高,且观察组高于对照组;两组龈沟液可溶性细胞间黏附分子-1水平均降低,观察组低于对照组(P<0.05)。结论自锁托槽矫治器可有效提高牙周病患者的正畸效果以及咀嚼效能,降低牙龈下菌斑中致病菌分布率,同时还能够减轻患者龈沟液内相关炎症反应,改善患者的牙周健康。

Objective To explore the effect of self-locking bracket appliance in patients with periodontal disease.Methods Forty-two patients with periodontal disease treated with traditional bracket aligners admitted to the First Affiliated Hospital of Zhengzhou University from June 2018 to February 2021 were retrospectively included as the control group,and 84 patients with periodontal disease treated with self-ligating bracket aligners were retrospectively included in the same period as the observation group,and both groups were followed up until the completion of treatment.The two groups were compared in terms of masticatory efficiency before and after completion of treatment,orthodontic effect after completion of treatment,pain intensity at each time point,inflammatory factor of gingival sulcus fluid,periodontal index,and distribution of causative organisms in the subgingival plaque before treatment and after 8 weeks of treatment.Results Compared with the pre-treatment,the masticatory efficacy of both groups was reduced after the completion of orthodontic treatment,and the observation group was lower than the control group(P<0.05).After the completion of orthodontic treatment,the total clinical orthodontic effectiveness rate in the control group(76.19%)was lower than the observation group(96.43%)(P<0.05).The gingival sulcus fluid levels of tumour necrosis factor-alpha,C-reactive protein,the plaque index,the gingival sulcus bleeding index and gingival index were all higher after 8 weeks of treatment compared with the pre-treatment period,but the observation group was lower than the control group.The gingival sulcus fluidβ-defensin 2 levels of two groups were increased,and the observation group was higher than the control group.The gingival sulcus fluid soluble intercellular adhesion molecule-1 levels of two groups were decreased,and the observation group was lower than the control group(P<0.05).Conclusion Self-locking bracket appliance can effectively improve the orthodontic effect as well as masticatory efficiency of patients with periodontal disease,reduce the distribution rate of pathogenic bacteria in subgingival plaque,and also reduce the inflammatory response associated with patients’gingival sulcus fluid,improving patients’periodontal health.
