摘 要:目的 评价新方法制作个别托盘对家庭漂白临床疗效的影响。方法 将25例着色牙患者的上前牙随机分为左右两组。一组按常规方法准备模型,另一组采用新方法。分别于漂白前、漂白后4w记录上前牙的颜色,并记录患者牙齿敏感及牙龈刺激的情况。结果 漂白4w后牙齿颜色有显著改变。使用两种个别托盘漂白牙的效果无差异,牙齿敏感及牙龈刺激亦无差异。结论 新方法制作个别托盘对家庭漂白临床疗效无不利影响,值得在临床上推广。Objective To evaluate the effects of new custom-tray fabricating technique on teeth bleaching. Methods Twenty-five patients with discolored teeth were involved in the study. The maxillary anterior teeth were randomly divided into two groups. Trays of one group were fabricated with traditional method, the others with new technique. The shades of teeth were evaluated at baseline and 4th week after bleaching. Teeth and gingival sensitivity were also collected during the study. Results There were significant differences on shades of teeth between baseline and after 4th week bleaching. But the differences between two groups were not significant at baseline and after 4th week bleaching. There were not difference on teeth and gingival sensitivity between two groups either. Conclusion There are not adverse effects of new custom-tray fabricating technique on teeth bleaching.
