摘要: 目的: 探讨增龄性变色牙和轻中度四环素牙冷光美白的临床效果。方法: 按着色原因及程度,将152例接受冷光美白的患者分为增龄性变色组、轻度四环素牙组和中度四环素牙组。利用16 色 Vita 比色板视觉比色法和Crystaleye 分光光度比色仪进行美白前、后牙色度对比,采用SPSS17.0软件包对3组美白效果进行统计学分析。结果: 视觉比色法评估显示,冷光美白对于增龄性变色组的有效率显著高于轻度和中度四环素牙组(P<0.05)。比色仪法评估显示中度四环素牙冷光美白后牙颈部、体部和切端的ΔE值均低于增龄性变色牙及轻度四环素牙(P<0.05),2组四环素牙冷光美白后牙颈部ΔE值显著高于体部和切端(P<0.05)。结论: 冷光美白技术对外源性染色的增龄性变色牙效果优于内源性四环素牙,冷光美白可以改善四环素牙颈部着色更深的问题。

Abstract: PURPOSE: To evaluate the clinical effectiveness of cold-light whitening technique on tetracycline pigmentation teeth and aged extrinsic stain teeth. METHODS: One hundred and fifty-two cases bleached by cold-light whitening technique were included in this study. The patients' teeth were divided into 3 groups: aged extrinsic stain teeth, mild tetracycline pigmentation teeth and moderate tetracycline pigmentation teeth. Visual determination of shade and Olympus crystaleye spectrophotometer were used to measure the tooth discoloration after bleaching. SPSS17.0 software package was used for statistical analysis. RESULTS: Visual determination showed that the efficiency of aged extrinsic stain teeth was significantly higher than that of mild and moderate tetracycline teeth group (P<0.05). Colorimetric method showed that the △E of moderate tetracycline teeth was significantly lower than aged extrinsic teeth and mild tetracycline teeth (P<0. 05) . The △E of cervix changed more significantly than that of central and incisal edge in both mild and moderate tetracycline teeth group (P<0. 05). CONCLUSIONS: The effect of cold-light whitening technique on aged extrinsic stain teeth is better than that of the tetracycline pigmentation teeth. Cold-light whitening technique can improve pigmentation of tetracycline teeth cervix.
