| 目的评价Wy10美白法漂白活髓着色牙的疗效和安全性。方法用Wy10美白系统对30例患者393颗活髓着色牙进行漂白,对照组30例患者378颗活髓着色牙采用Beyond冷光美白法。利用Vita比色板色值测定法、计算机辅助分析法评价美白疗效,并通过牙髓敏感性比较问卷评估牙齿敏感情况。结果Wy10美白组与冷光美白组漂白有效率差异无统计学意义(P>0.05);两组漂白治疗前、后牙面颜色的色差值差异也无统计学意义(P>0.05)。但两组患者在术后即刻、术后1周、术后3个月、术后6个月的牙髓敏感率差异有统计学意义(P<0.05)。结论 Wy10美白与冷光美白对活髓着色牙的漂白疗效无明显差异,但Wy10美白较冷光美白对牙髓的刺激性轻,临床应用安全性更好。 |
