目的：这项前瞻性队列研究的目的是探讨功能旁咬肌活动对牙周支持疗法(SPT)患者牙周炎进展的影响。材料和方法收集了2014年8月至2018年9月在冈山大学医院接受治疗的患者的数据。进展组的定义是：在3年的研究期间，≥2牙齿表现出≥3 mm近端附着体纵向丧失和/或至少一颗牙齿因牙周炎进展而拔除。结果分析48例患者(36例女性)，年龄(66.8±10.9)岁，平均(6±9.1)岁。基础状态下清醒时和睡眠时功能旁咬肌活动率分别为60.4%和52.1%。COX比例风险回归模型显示，牙周炎进展的发生率与存在的牙数(p=0.001)和清醒时的功能旁咬肌活动(p=0.041)显著相关。结论我们的结果提示，在接受牙周矫治的患者中，功能旁功能咬肌活动是牙周炎进展的危险因素。
AimThe purpose of this pilot prospective cohort study was to investigate the effects of parafunctional masseter muscle activity on periodontitis progression among patients receiving supporting periodontal therapy (SPT).Materials and methodsWe collected data of patients treated at Okayama University Hospital from August 2014 to September 2018. The progression group was defined as patients with ≥2 teeth demonstrating a longitudinal loss of proximal attachment of ≥3 mm during the 3‐year study period and/or at least one tooth extraction due to periodontitis progression. Surface electromyography of masseter muscles at baseline was continuously recorded while patients were awake and asleep.ResultsWe analysed 48 patients (36 females) aged 66.8 ± 9.1 years (mean ± SD). The rate of parafunctional masseter muscle activity during waking hours and sleeping hours at baseline was 60.4% and 52.1%, respectively. Cox's proportional hazards regression model showed that the incidence of periodontitis progression was significantly associated with number of teeth present (p= 0.001) and parafunctional masseter muscle activity during waking hours (p= 0.041).ConclusionOur results suggest that parafunctional masseter muscle activity during waking hours is a risk factor for periodontitis progression among patients receiving SPT.
