摘要: 目的: 探讨低强度激光联合全口刮治和根面平整(full-mouth scaling and root planning,FM-SRP)治疗对慢性牙周炎患者龈沟液中转化生长因子β1(transforming growth factor β1, TGF-β1)、组织纤溶酶原激活物(tissue plasminogen activator, t-AP)和纤溶酶原激活物抑制剂1 (plasminogen activators-1, PAI-1)水平的影响。方法: 选择2019年10月~2021年8月本院收治的28例慢性牙周炎患者,本文为前瞻性研究,随机数表法将患者分成观察组和对照组,对照组患者行FM-SRP治疗,观察组患者行FM-SRP治疗辅以低强度激光。比较两组患者疼痛评分,炎性因子,牙周状态指标,血管内皮功能,龈沟液TGF-β1、t-AP和PAI-1及不良反应等参数。结果: 观察组患者治疗后3 d疼痛评分明显低于对照组。治疗后,观察组患者牙龈出血指数、牙周袋探诊深度、牙周附着丧失距离和菌斑指数明显低于对照组;观察组患者白细胞介素-8、基质金属蛋白酶-7和高迁移率族蛋白B1等炎性因子水平明显低于对照组,观察组患者血管扩张功能和血管舒张功能等血管内皮功能明显高于对照组;观察组患者龈沟液转化生长因子β1和t-AP明显高于对照组,观察组患者龈沟液PAI-1水平明显低于对照组。结论: 低强度激光联合FM-SRP应用于慢性牙周炎疾病的治疗,可有效缓解疼痛程度,消除炎症反应,提高血管内皮功能,改善牙周状态指标,可能与降低龈沟液转化生长因子和t-AP、提高PAI-1水平,安全性高,值得临床推广。

Abstract: Objective: To explore the effects of low intensity laser combined with FM-SRP on the levels of TGF-β1, t-AP, and PAI-1 in gingival crevicular fluid of patients with chronic periodontitis. Methods: In this prospective study, 28 patients with chronic periodontitis admitted to our hospital from October 2019 to August 2021 were selected and divided into observation group and control group by random number table method. Patients in the control group received FM-SRP treatment, and patients in the observation group received FM-SRP treatment supplemented by low-intensity laser. Pain score, periodontal clinical indicators, inflammatory factors, vascular endothelial function, GCF transforming growth factor, t-AP, PAI-1, and adverse reactions were compared between two groups. Results: The pain score in the observation group was significantly lower than that of control group at 3d after treatment. After treatment, gingival bleeding index, probing depth, clinical attachment loss, and plaque index in the observation group, were significantly lower than those in the control group. Interleukin-8, matrix metalloproteinase-7, and high mobility group protein B1 in the observation group were significantly lower than those in the control group. The FMD and NMD in the observation group were significantly higher than those in the control group ingival crevice fluid transforming growth factor β1 and t-AP in the observation group were significantly higher than those in the control group, and the PAI-1 of gingival crevicular fluid in the observation group was significantly lower than that in the control group. Conclusion: Low intensity laser combined with FM-SRP in the treatment of chronic periodontitis can effectively relieve pain, eliminate inflammation, improve vascular endothelial function, improve periodontal status indicators, and may be associated with the reduction of gingival crevicular fluid transforming growth factor and t-AP and improvement of PAI-1 level, which is safe and worthy of clinical promotion.
