摘　　要：目的:观察牙周非手术治疗对导致根面牙本质敏感症的影响,并探讨其机理。方法:对52例慢性牙周炎患者的1453颗牙进行龈下刮治及根面平整术,随访3个月。总结治疗后患者根面牙本质敏感症的发生情况。结果:52例患者中,39例共432颗牙发生了不同程度的根面牙本质敏感症,给予积极治疗后症状大多消失。龈下刮治术和根面平整术可使部分牙本质小管敞开暴露于口腔环境中,使外来刺激遵循液体动力学原理激发痛觉。结论:脱敏治疗应纳入牙周治疗计划中。PURPOSE: To study the effects of non-surgical periodontal treatment on the occurrence of root-dentin hypersensitivity and explore its mechanisms through clinical obeservations. METHODS: 1453 teeth of 52 patients with chronic periodontitis were given scaling and root-planing procedures. 3 months follow-up of these teeth were taken to find root-dentin hypersensitivity after treatment.RESULTS: 432 teeth of 39 patients had different degree of root-dentin hypersensitivity.However,the symptoms disappeared in most patients after active desensitization treatment.CONCLUSION:Subgingival scaling and root-planing can induce the occurrence of root dentin hypersensitivity,therefore, desensitization treatment should be considered as a part of periodontal treatment plan.
