The aim of this study was to evaluate the clinical behavior of prefabricated componeers and direct composite veneering. The objective of the study was to compare the changes in color, surface texture, marginal integrity, and gingival response for componeers and direct composite veneers.
This was an , comparative study.
Ten patients indicated for anterior veneers were selected and divided into Groups A and B of five patients each. Group A was restored with componeers and Group B with direct composite veneers. Both the groups were compared for color changes, surface textural changes, marginal integrity, and gingival response, starting immediately post veneering and at 3, 6, 9, and 12 months subsequently.
Friedman's two-way analysis of variance and Mann-Whitney test were used for statistical analysis.
Results for color ranged from excellent to good with minimal color changes post veneering. Overall, "gingival response," in both the groups, showed statistically significant differences in mean rank scores ( ≤ 0.05). The data depicted an improvement in gingival response for all patients during the period of the study. Surface textural changes were significant only for maxillary right canine and maxillary left lateral incisor ( = 0.024 and 0.039, respectively) in both the groups. Maxillary right canine in both the groups showed significant changes in marginal integrity. Intergroup comparison of gingival response, surface texture, and marginal integrity depicted no significant difference between the groups ( > 0.05).
This study concluded that the intergroup comparison of componeers and direct composite veneers for the parameters, gingival response, surface texture, and marginal integrity did not depict any significant differences. Both the groups displayed minimal changes in color, surface texture, and marginal integrity and improved gingival response.
本研究旨在评估预制组件式修复体和直接复合树脂贴面的临床性能。本研究的目的是比较组件式修复体和直接复合树脂贴面在颜色、表面质地、边缘完整性和牙龈反应方面的变化。
这是一项比较性研究。
选择10例需要进行前牙贴面修复的患者,分为A组和B组,每组5例。A组采用组件式修复体修复,B组采用直接复合树脂贴面修复。比较两组在贴面修复后即刻以及随后3个月、6个月、9个月和12个月时的颜色变化、表面质地变化、边缘完整性和牙龈反应。
采用弗里德曼双向方差分析和曼-惠特尼检验进行统计分析。
颜色结果从优到良,贴面修复后颜色变化极小。总体而言,两组的“牙龈反应”在平均秩次得分上显示出统计学显著差异(P≤0.05)。数据表明,在研究期间所有患者的牙龈反应均有改善。两组中仅上颌右侧尖牙和上颌左侧侧切牙的表面质地变化具有统计学意义(分别为P = 0.024和0.039)。两组上颌右侧尖牙的边缘完整性均有显著变化。牙龈反应、表面质地和边缘完整性的组间比较显示两组之间无显著差异(P>0.05)。
本研究得出结论,对于牙龈反应、表面质地和边缘完整性这些参数,组件式修复体和直接复合树脂贴面的组间比较未显示出任何显著差异。两组在颜色、表面质地和边缘完整性方面均显示出极小的变化,且牙龈反应有所改善。
