Abstract：
Nowadays, the ceramic veneer approach can be considered more predictable than direct composite veneer. To date, there is a lack of studies comparing the clinical performance of anterior veneers cemented on vital teeth (VT) and non-vital teeth (NVT). This longitudinal clinical study investigated the performance of ceramic veneers in VT or anterior NVT. A total of 55 patients were evaluated in the study. Two groups were defined based on the vitality status of the teeth (93 teeth-vital and 61 teeth-non-vital). The United States Public Health Service (USPHS) criteria were used to assess the clinical status. The data were evaluated statistically with the Mann-Whitney U test. All restorations were considered acceptable, and only one veneer in VT failed for the criteria of secondary caries. There were no statistically significant differences in any of the criteria evaluated (p ≤ 0.671). The ceramic veneers evaluated showed a satisfactory clinical performance both in VT and NVT.
摘要：
如今,陶瓷贴面方法可以被认为比直接复合贴面更可预测。迄今为止,缺乏比较在活生牙(VT)和非活生牙(NVT)上骨水泥的前贴面的临床表现的研究。这项纵向临床研究调查了陶瓷贴面在VT或前NVT中的性能。在研究中评估了总共55名患者。根据牙齿的活力状况定义了两组（93颗重要牙齿和61颗非重要牙齿）。美国公共卫生服务（USPHS）标准用于评估临床状态。使用Mann-WhitneyU检验对数据进行统计学评估。所有修复都被认为是可以接受的，VT中只有一个单板不符合继发性龋齿的标准。在评估的任何标准中都没有统计学上的显着差异（p≤0.671）。评估的陶瓷贴面在VT和NVT中均显示出令人满意的临床表现。
