摘要
目的:评价超薄瓷贴面在前牙修复时的色彩效果,以及医患满意度的影响因素。方法:将30名超薄瓷贴面修复的患者,分为四环素牙组(A组:9例72个贴面),非四环素牙组(B组:21例66个贴面),分别在修复前、修复后1周,用Olympus Crystaleye分光光度比色仪测定患牙色度值L*、a*、b*值,并参照患者意愿选定期望色。应用SPSS20. 0软件分析2组修复前后临床效果,贴面修复后颜色与期望色色差(ΔE1)的差异,医患对修复体颜色的满意度与ΔE_1、ΔL*、Δa*、Δb*之间的关系。结果:超薄瓷贴面修复前后L*、a*、b*值的差异均有显著性(P <0. 05); A、B 2组之间的期望恢复色色差ΔE_1有统计学意义(P <0. 05);ΔE_1、ΔL*、Δa*与医生、患者满意度的相关性有统计学意义(P <0. 05)。结论:应用超薄瓷贴面修复非四环素牙可达到理想的颜色效果,修复后颜色与期望值越接近,满意度越高。修复前后明度差越小,满意度越高。
Objective: To evaluate the color effect of esthetic rehabilitation of anterior teeth restored with the minimal and no-preparation veneers and to analyze the influence factors of satisfaction. Methods: 30 patients were divided into group A( 9 patients with tetracycline discoloured teeth treated with 72 veneers) and group B( 21 patients with non-tetracycline teeth treated with 66 veneers). All the selected teeth were restored with the minimal and non-preparation veneers. Before the teeth were prepared and after veneers were cemented,Olympus Crystaleye was employed to obtain L*,a*,b*values of each tooth. The shade was selected according to the patients’ expectation and dentist’s advice. The color difference( ΔE) before and after restoration of group A and group B,the color difference( ΔE1) between the tooth color after restoration and the expectation color of the patients,the relationship of the satisfaction degree and the color difference( ΔE1),the lightness difference( ΔL*),Δa*and Δb*were analyzed by SPSS 20. 0. Results: After cemented,the color of teeth-veneer-complex obviously improved in both groups. The color difference( ΔE1) between the tooth color before and after restoration,and the expected color between the 2 group was significant( P < 0. 05). ΔE1,ΔL*,Δa*had great influence on the satisfaction of dentists and patients( P < 0. 05). Conclusion: The appearance of non-tetracycline teeth restored with the minimal and no-preparation veneers was excellent. The more of the color of the teeth-veneer-complex matched the expectation color,the higher the patients are satisfied with the restorations. The less of the lightness difference,the higher the patients are satisfied with the restorations.
