Abstract
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。
