龈下刮治和根面平整术后牙本质过敏的临床评价

目的 评价龈下刮治和根而平整术后牙本质过敏的发生率和敏感程度.方法 分别在手术前以及手术后5 min、1周和4周对38例接受龈下刮治及根面平整术的慢性牙周炎患者行温度试验,采用视觉疼痛模拟评分(VAS)对其牙的敏感程度进行评估,比较术前术后牙本质过敏的发生率和敏感程度.结果 术后1周,牙本质过敏的发生率(52.6%)显著高于术前(28.9%),过敏牙的VAS(4.1±1.7)也显著高于术前(2.9±1.7),差异均有统计学意义(P<0.05);术后4周,牙本质过敏的发生率和VAS显著下降,与术前相比较差异无统计学意义(P>0.05).结论 龈下刮治和根面平整术是牙本质过敏的一个诱发因素.

Clinical evaluation of dentine sensitivity after scaling and root planing

Objective To evaluate the prevalence and intensity of dentine sensitivity(DS) after scaling and root planing. Methods The study was carried out with 38 subjects who had chronic periodontitis requiring for scaling and root planing. DS was scored by the subjects on a 0-10 visual analogue scale(VAS) after cold air stimulation of the test teeth at baseline and 5 minutes after the treatment, 1 week after the treatment and 4 weeks after the treatment. The prevalence and intensity of DS was compared between the ba...
