【摘要】：目的:探讨Beyond冷光美白治疗前应用VivaSens脱敏剂对美白术后牙齿敏感治疗的有效性及对美白效果的影响,阐明其在冷光美白术中的应用价值。方法:选择门诊牙齿冷光美白患者15例,共299颗患牙。以患者的上颌牙列或下颌牙列(包括前牙及前磨牙)的牙列整体作为观察单位,随机确定每个患者上颌牙列或下颌牙列作为实验组和对照组。实验组患者15例,共150颗患牙,其中上颌牙列8个,下颌牙列7个;对照组15例,共149颗患牙,其中上颌牙列7个,下颌牙列8个。实验组术前使用VivaSens脱敏剂,对照组应用安慰剂。术前、术后应用探针测试法和冷空气测试法测定并记录患者患牙的敏感度,记为0~10。术后发放调查问卷,询问术后24和48h有无牙齿敏感症状。术前、术后应用Vita比色板进行比色并做色阶记录。结果:术后即刻,实验组101颗患牙(94.0%)和对照组全部患牙(100%)出现了牙本质敏感,牙本质敏感发生率组间比较差异有统计学意义(P0.01);术后24h,实验组有22颗患牙(14.7%)、对照组有75颗患牙(50.3%)仍有牙本质敏感症状,牙本质敏感发生率组间比较差异有统计学意义(P0.01);术后48h,实验组患牙牙本质敏感症状均消失,对照组仍有16颗患牙(10.7%)有牙本质敏感症状,牙本质敏感发生率组间比较差异有统计学意义(P0.01)。实验组各阶段牙本质敏感度均低于对照组(P0.05)。Vita比色板比色,术后与术前比较,实验组与对照组均提高了约5个色阶,2组间美白效果比较差异无统计学意义(P0.05)。结论:VivaSens脱敏剂能有效降低冷光美白术后牙本质敏感发生率和敏感度,而且不影响冷光美白的效果。
[Abstract]:Objective: to investigate the effect of VivaSens desensitizer on the treatment of tooth sensitivities after whitening after Beyond and its effect on whitening, and to elucidate the value of VivaSens desensitizer in the operation of cold light whitening. Methods: a total of 299 teeth were selected from 15 patients with tooth whitening. The maxillary dentition or mandibular dentition (including anterior teeth and premolars) was taken as the observation unit, and each patient's maxillary dentition or mandibular dentition was randomly selected as the experimental group and the control group. There were 15 patients in the experimental group with 150 teeth, including 8 maxillary dentition and 7 mandibular dentition, while in the control group, there were 149 teeth, including 7 maxillary dentition and 8 mandibular dentition. VivaSens desensitizer was used before operation in the experimental group and placebo was used in the control group. Before and after operation, the sensitivity of the affected teeth was measured and recorded by probe test and cold air test. Questionnaires were sent out after operation to ask if there were any symptoms of tooth sensitivity 24 and 48 hours after operation. Before and after operation, Vita colorimetric plate was used for colorimetry and color scale was recorded. Results: immediately after operation, 101 teeth (94.0%) in the experimental group and 100% (100%) in the control group developed dentin sensitivity. There were significant differences in the incidence of dentin sensitivity between the two groups (P0.01), 22 teeth (14.7%) in the experimental group and 75 teeth (50.3%) in the control group at 24 hours after operation. There was significant difference in the incidence of dentin sensitivity between the two groups (P0.01), and at 48h after operation, the symptoms of dentine sensitivity disappeared in the experimental group and 16 teeth (10.7%) in the control group. There was significant difference in the incidence of dentin sensitivity between the two groups (P 0.01). The sensitivity of dentin in the experimental group was lower than that in the control group (P0.05) .Vita colorimetric plate colorimetry was significantly lower than that in the control group (P0.05), and there was no significant difference in the whitening effect between the experimental group and the control group (P0.05). ConclusionViva Sens desensitizer can effectively reduce the incidence and sensitivity of dentin sensitivity after cold light whitening, and does not affect the effect of cold light whitening.
