摘要
目的:评价氟斑牙冷光美白应用祛氟剂及微打磨技术的效果。方法:将四川省第四人民医院口腔科2012年8月—2015年7月收治的122例中度氟斑牙患者按照随机数字表法分为研究组和对照组,每组61例。全部患者实施预处理。对照组实施Beyond冷光美白治疗联合祛氟剂涂抹治疗。研究组在冷光美白治疗之前实施微打磨治疗,后续治疗同对照组。比较2组治疗完成时、治疗后1个月及6个月的牙美白效果及美白治疗时的牙敏感度。采用SPSS19.0软件包对数据进行统计学分析。结果:2组均无无效病例,均无失访病例。研究组治疗完成时、治疗1个月后及6个月后美白效果均显著高于对照组(P<0.05)。治疗过程中无牙极敏感病例。2组不显著敏感率及显著敏感率均无显著差异(P>0.05)。结论:氟斑牙冷光美白时应用祛氟剂及微打磨技术可显著提高美白效果,且不会因显著增加牙敏感性而导致治疗中断。
PURPOSE： To evaluate the effect of fluoride removal agent and microabrasion technology in LED teeth whitening of dental fluorosis. METHODS： One hundred and twelve patients with moderate dental fluorosis treated from August 2012 to July 2015 were divided into experimental group and control group according to random number table, with 61 cases in each group. In addition to pretreatment for all patients, patients in the control group were given combined treatment of Beyond LED whitening and fluoride removal agent; while patients in the experimental group were given microabrasion before LED whitening, with the same subsequent treatment process as that in the control group. The whitening effect and tooth sensitivity during whitening were compared between the two groups at the completion of treatment, 1 month and 6 months after treatment. SPSS 19.0 software package was employed for statistical analysis. RESULTS： There were no ineffective or lost patients in 2 groups. The effective rate of whitening for patients in the experimental group at completion of treatment, 1 month and 6 months after treatment was significantly higher than that in the control group （P〈0.05）. There was no case with tooth sensitivity during treatment. There was no significant difference in non-significant sensitivity rate or significant sensitivity rate between the 2 groups （P〉0.05）. CONCLUSIONS： Combined treatment with fluoride removal agent and mieroabrasion technology in LED teeth whitening for dental fluorosis can significantly improve the whitening effect and will not interfered by significantly increased tooth sensitivity.
