冷光美白治疗氟斑牙的初步探讨

目的：观察Beyond牙齿冷光美白治疗氟斑牙的效果。方法：选取10名受试者,用Beyond牙齿冷光美白进行漂白治疗。术前和术后分别采用数码照像计算机色度分析系统对上颌中切牙进行比色,术后1年复查受试者牙齿的色度变化。结果：术前受试者上颌中切牙的平均L＊,a＊,b＊值为73.89±2.80,7.77±1.05和21.50±1.21,经过Beyond牙齿冷光美白三次治疗后上颌中切牙的平均L＊,a＊,b＊值为82.95±2.42,3.39±0.91和12.97±1.36,平均色差ΔE＊ab为13.18±1.53。术后1年复查受试者上颌中切牙的平均L＊,a＊,b＊值为81.50±2.10,3.69±0.76和13.66±1.32,平均色差ΔE＊ab为11.45±1.64。结论：Beyond牙齿冷光美白对氟斑牙具有较好的漂白效果,并能较长时间维持漂白效果。

The study of the bleaching effect of BEYOND WHITENING ACCELERATOR to dental fluorosis

Objective：To observe the bleaching effect of BEYOND WHITENING ACCELERATOR to dental fluorosis.Methods： Ten patients were selected to receive the bleaching treatment with BEYOND WHITENING ACCELERATOR.The tooth color of maxillary central incisor was detected with Color analysis system of digital camera and computer before and after the treatment.The color improvement maintained was assessed after 1 year.Results： The average L＊,a＊,b＊ value of maxillary central incisor was 73.89 ±2.80,7.77 ±1.05 and 21.50 ±1.21 before the treatment.After BEYOND WHITENING ACCELERATOR treatment three times,the average L＊,a＊,b＊ value of maxillary central incisor was 82.95±2.42,3.39±0.91 and 12.97±1.36,the average color difference（Δ E＊ab） was 13.18±1.53.After 1 year,the average L＊,a＊,b＊ value was 81.50±2.10,3.69±0.76 and 13.66±1.32,the average color difference（Δ E＊ab） was 11.45±1.64.Conclusion： The bleaching effect of BEYOND WHITENING ACCELERATOR is good and can maintain the bleaching effect of a longer time.
