The aim of this study was to compare and evaluate Putty Index and Custom Template Technique for Direct Composite restoration of uncomplicated crown fractures in permanent anterior teeth.
A total of 100 teeth were randomly allocated to the respective groups, n=49 in Group I and n=51 in Group II. Composite build up using Putty Index technique in Group I and vacuum formed Custom Template in Group II was done followed by finishing and polishing of the restoration. The restorations were scored using Modified USPHS criteria by two blinded and calibrated evaluators at baseline, 6 months and 12 months followed by Spectrophotometric evaluation. The clinical chair side time was recorded using digital clock.
No statistically significant difference was seen between ITT and PP analysis among the two groups at 6 months and 12 months follow-up. Mean time chair side time taken for Group I was 20 minutes and for 24.4 minutes for Group II which was statistically significant (P=0.00). No statistically significant change was seen in the colour of the restoration at 6 months (P=0.45) and 12 months (P=1.00) using spectrophotometer.
Custom Template technique and Putty Index technique showed no statistically significant difference in terms of clinical evaluation at baseline, 6 months and 12 months except for postoperative sensitivity.
本研究旨在比较和评估用于恒牙前牙单纯冠折直接复合树脂修复的油灰指数法和定制模板技术。
总共100颗牙齿被随机分配到各自的组中，第一组n = 49颗，第二组n = 51颗。第一组使用油灰指数技术进行复合树脂堆积，第二组使用真空成型的定制模板，然后对修复体进行修整和抛光。在基线、6个月和12个月时，由两名盲法且经过校准的评估者使用改良的美国公共卫生服务标准对修复体进行评分，随后进行分光光度评估。使用数字时钟记录临床椅旁时间。
在6个月和12个月的随访中，两组的意向性分析（ITT）和符合方案分析（PP）之间未观察到统计学上的显著差异。第一组的平均椅旁时间为20分钟，第二组为24.4分钟，具有统计学显著性（P = 0.00）。使用分光光度计在6个月（P = 0.45）和12个月（P = 1.00）时，修复体颜色未观察到统计学上的显著变化。
除术后敏感性外，定制模板技术和油灰指数技术在基线、6个月和12个月的临床评估方面未显示出统计学上的显著差异。
