J Clin Exp Dent:激光可有效治疗牙本质敏感

2017-07-11 MedSci MedSci原创

牙本质过敏常见于人群中,导致患者感觉不适,且在接受基本或外科牙周治疗的患者中患病率较高。已有研究使用不同波长的二极管激光器来治疗牙本质过敏,结果显示改善率达60-98 %。本研究旨在评估的牙周非手术治疗后使用光生物效应(PBM)治疗牙本质过敏的效果。采用随机分次口腔临床试验,纳入30名经洁刮治治疗后诊断为牙本质过敏的患者(120颗牙)。实验侧用激光处理两颗牙齿,对照组两颗牙齿则不经激光治疗。每颗牙

牙本质过敏常见于人群中,导致患者感觉不适,且在接受基本或外科牙周治疗的患者中患病率较高。已有研究使用不同波长的二极管激光器来治疗牙本质过敏,结果显示改善率达60-98 %。本研究旨在评估的牙周非手术治疗后使用光生物效应(PBM)治疗牙本质过敏的效果。

采用随机分次口腔临床试验,纳入30名经洁刮治治疗后诊断为牙本质过敏的患者(120颗牙)。实验侧用激光处理两颗牙齿,对照组两颗牙齿则不经激光治疗。每颗牙的激光治疗参数为660nm,200mW、CW、照射面积1.15cm2,173mw/cm2,60秒,12 J,10.4j/cm2。在治疗前、治疗后(2分钟)、治疗后2周、1个月和2个月分别记录年龄、性别、吸烟、菌斑指数、牙龈退缩、探诊深度和VAS(触觉和热刺激)。

结果,在所有评价期间,对照组和实验组治疗部位对热刺激和机械刺激的不适感上存在显著性差异(p<0.01)。在半导体激光治疗后,患者的不适感状况立即下降,并在研究期间持续下降。激光治疗后所有牙齿仍保持活力,无不良反应或并发症。

总而言之,该研究表明,PBM可以用来减少牙本质敏感而不会损伤牙髓。
