Beyond冷光美白联合二矽酸锂基铸瓷贴面修复中重度氟斑牙的效果评价

Effect Evaluation of Beyond Cold Light Whitening Combined with Lithium Disilicate Based Ceramic Veneer for Severe Dental Fluorosis

目的评价Beyond冷光美白联合二矽酸锂基铸瓷贴面对中重度氟斑牙的治疗效果。方法将中重度氟斑牙患者160例分为冷光美白组80例,非冷光美白组80例。两组均进行二矽酸锂基铸瓷贴面修复,治疗前、后用VITA比色板进行牙齿比色和照相记录,评估患者治疗满意度。结果冷光美白组中度患者满意率为96.4%,重度患者满意率为88%;非冷光美白组中度患者满意率为84.7%,重度患者满意为52.4%。中度氟斑牙患者冷光美白组治疗满意率高于非冷光美白组,差异有统计学意义(X^2=4.407,P<0.05);重度患者治疗满意率也高于非冷光美白组(X^2=7.142,P<0.01)。结论对于中重度的氟斑牙修复治疗,Beyond冷光美白联合二矽酸锂基铸瓷贴面修复技术,较单独使用二矽酸锂基铸瓷贴面修复疗效更佳。

Objective To evaluate effect of Beyond cold light whitening combined with lithium disilicate based ceramic veneer in treatment of severe dental fluorosis. Methods Divide 160 cases severe dental fluorosis patients into cold light whitening group 80 cases, and non cold light whitening group 80 cases of. Carry on lithium disilicate porcelain veneer repairation for two groups. Before and after treatment, carry on tooth colorimetric and photographic records with VITA shade guide, and evaluate patient＇s satisfaction. Results Satisfaction degree of cold light whitening group was 96.4%, satisfaction degree of severe patients was 88%, satisfaction degree of non cold light whitening group was 84.7%, and satisfaction degree of severe patients was 52.4%. Satisfaction degree of moderate dental fluorosis patients in cold light whitening group was higher than non cold light whitening group, difference showed statistical significance,（X～2=4.407, P〈0.05）; satisfaction degree of severe patietns was also higher than non whitening group（X～2=7.142, P〈0.01）. Conclusion Beyond cold light whitening combined with lithium disilicate based ceramic veneer repairation has better effect than lithium disilicate based ceramic veneer only in treatment of moderate and severe dental fluorosis.
