Therefore, the aim of this clinical investigation was to analyze the relationship between sleep bruxism and several functional and occlusal parameters. The null hypothesis of this study was that there would be no differences among sleep bruxism subjects and non-sleep bruxism controls regarding several functional and occlusal parameters. Fifty-eight sleep bruxism subjects and 31 controls participated in this study. The diagnosis sleep bruxism was based on clinical criteria of the American Academy of Sleep Medicine. Sixteen functional and occlusal parameters were recorded clinically or from dental study casts. Similar to the recently published retrospective pilot study, with a mean slide of 0.77 mm （s.d., 0.69 mm） in the sleep bruxism group and a mean slide of 0.4 mm （s.d., 0.57 mm） in the control group, the evaluation of the mean comparison between the two groups demonstrated a larger slide from centric occlusion to maximum intercuspation in sleep bruxism subjects （Mann-Whitney U-test; P=O.O08）. However, following Bonferroni adjustment, none of the 16 occlusal and functional variables differed significantly between the sleep bruxism subjects and the non-sleep bruxism controls. The present study shows that the occlusal and functional parameters evaluated do not differ between sleep bruxism subjects and non-sleep bruxism subjects. However, as the literature reveals a possible association between bruxism and certain subgroups of temporomandibular disorders, it appears advisable to incorporate the individual adaptive caoacitv of the stomatognathic svstem into future investigations.展开更多
目的研究A型肉毒杆菌毒素(botulinum toxin,BTX-A)对青年磨牙患者的临床治疗效果。方法选取2020年9月至2022年3月浙江树人大学树兰国际医学院附属树兰(杭州)医院接诊的42例夜磨牙症患者,采用随机数字表法分为对照组(n=21)和试验组(n=21...目的研究A型肉毒杆菌毒素(botulinum toxin,BTX-A)对青年磨牙患者的临床治疗效果。方法选取2020年9月至2022年3月浙江树人大学树兰国际医学院附属树兰(杭州)医院接诊的42例夜磨牙症患者,采用随机数字表法分为对照组(n=21)和试验组(n=21)。治疗前对两组进行多导睡眠监测和疼痛视觉模拟评分(visual analog scale,VAS)评估,试验组咬肌区注射BTX-A,对照组咬肌区注射生理盐水,注射4周后再次进行多导睡眠监测和疼痛评估,比较两组治疗前后多导睡眠监测参数、咀嚼肌节律性运动(rhythmic masticatory muscle activity,RMMA)事件参数、疼痛水平和不良反应情况。结果注射4周后,两组多导睡眠监测参数比较,差异均无统计学意义(P>0.05)。试验组患者咀嚼肌节律性运动发作期间咬肌肌电爆发的峰值幅度(peak amplitude of electromyography burst in the masseter muscle during rhythmic masticatory muscle activity,RMMA.MA)及咬肌最大自主收缩时咬肌肌电爆发的峰值幅度(peak amplitude of electromyography burst in the masseter muscle during maximal voluntary clenching,MVC.MA)均低于对照组,差异均有统计学意义(P<0.05)。两组VAS均低于注射前且试验组低于对照组,差异均有统计学意义(P<0.05)。两组均未报告吞咽困难或咀嚼不良事件。结论A型肉毒杆菌毒素注射不能减少夜磨牙的发生,但其通过降低咬肌的强度能缓解夜磨牙症的牙齿磨损和咬肌酸痛,但长期效果仍需进一步观察。展开更多
