微研磨联合居家漂白治疗氟斑牙的疗效观察

Observation on the effect of micro-grinding combined with home bleaching in the treatment of dental fluorosis

目的观察皓齿Opalustre微研磨糊剂及Opalescence PF居家漂白套装治疗氟斑牙的临床疗效。方法选取2017年1月至2020年11月在我院口腔中心就诊的氟斑牙患者36例为研究对象,按照随机数字表法分为观察组和对照组,观察组19例用皓齿Opalustre微研磨糊剂在诊室内行着色牙釉质微打磨,再用10%Opalescence PF居家漂白套装漂白2周,对照组17例仅用Opalustre微研磨糊剂在诊室内行着色牙釉质微打磨。治疗前后用Vita比色板记录牙色变化,同时观察美白后牙齿的敏感程度,按疗效评定标准比较两组的临床效果。结果观察组19例患者中有18例治疗后牙色均明显提高,且无明显敏感情况出现。观察组总有效率为94.74%,明显高于对照组的70.58%,差异有统计学意义(P<0.05)。结论微研磨联合居家漂白治疗氟斑牙疗效肯定,值得临床推广应用。

Objective To observe the clinical efficacy of Opalustre micro-grinding paste and Opalescence PF home bleaching kit in the treatment of dental fluorosis.Methods A total of 36 patients with dental fluorosis who were treated in the dental center of our hospital from January 2017 to November 2020 were selected as the study subjects.According to the random number table method,they were divided into an observation group and a control group.In the observation group,19 patients in the observation group were given the Opalustre micro-grinding paste to perform colored enamel micro-grinding in the clinic,and then were given 10%Opalescence PF home bleaching kit to bleach for 2 weeks.The 17 patients in the control group were only given Opalustre micro-grinding paste to perform colored enamel micro-grinding in the clinic.Before and after treatment,Vita shade plate was used to record the change of teeth color.At the same time,the sensitivity of the teeth after whitening was observed.The clinical effects were compared between the two groups according to the efficacy evaluation criteria.Results 18 out of the 19 patients in the observation group showed a significant improvement in the teeth color after treatment,and there was no obvious sensitivity.The total effective rate was 94.74%in the observation group,which was higher than that of 70.58%in the control group,and the difference was statistically significant(P<0.05).Conclusion The combination of micro-grinding and home bleaching is effective in the treatment of dental fluorosis,which is worthy of clinical application.
