Mild-to-moderately severe enamel fluorosis (EF) is an unsightly maturation-phase dental disorder. Despite extensive epidemiological studies on EF, little is known about individual treatment options. This study was carried out to determine whether a simple microabrasion technique is effective in improving the esthetics of EF. Patients with a variety of severities were treated using a water-cooled fine diamond polishing bur at high speed to remove the surface enamel layers. Photographs of the affected teeth before and after treatment were shown by computer to a panel of three judges (two lay and one experienced), who rated the appearance of the teeth using a newly developed visual analog scale. The severity of EF was rated randomly and blind for 52 individual teeth (26 before and 26 after treatment). Reteated-measures analysis of variance was used to analyze the results. The lay judges rated the appearance of the teeth with EF as significantly more objectionable before treatment. All judges found a significant improvement in the severity of EF after treatment. Using a newly developed visual analog scale, our study indicates that EF of an objectionable nature can be significantly improved with a simple microabrasion technique, thus conserving tooth structure and minimizing the cost of treating EF.
轻至中度严重的釉质氟斑牙(EF)是一种影响美观的牙齿成熟阶段疾病。尽管对EF进行了广泛的流行病学研究,但对于个体治疗方案却知之甚少。本研究旨在确定一种简单的微磨除技术是否能有效改善EF的美观。使用水冷式细金刚石抛光车针高速去除不同严重程度患者的患牙表面釉质层。治疗前后患牙的照片通过计算机展示给由三名评判员(两名非专业人员和一名经验丰富的人员)组成的小组,评判员使用新开发的视觉模拟量表对牙齿外观进行评分。对52颗单颗牙齿(治疗前26颗,治疗后26颗)的EF严重程度进行随机、盲法评分。采用重复测量方差分析对结果进行分析。非专业评判员认为治疗前EF患牙的外观明显更令人反感。所有评判员均发现治疗后EF的严重程度有显著改善。使用新开发的视觉模拟量表,我们的研究表明,采用简单的微磨除技术可显著改善具有令人反感特征的EF,从而保留牙齿结构并降低治疗EF的成本。
