Comparative evaluation of postoperative sensitivity (POS) among three bulk fill restorative materials (Cention N, Equia Forte, Activa™ Bioactive restorative) in Class I posterior restorations.
One hundred and forty-four patients having occlusal caries were arbitrarily selected and divided into three groups. Standardized Class I cavity was prepared and restored with Cention N, Equia forte, and Activa™ Bioactive restorative material. POS of restored tooth was assessed with a standardized cold test and air stimulus by air blow from the air syringe. Patient responses were assessed at an interval of 24 h, 1 week, and 1 month using a visual analog scale. Statistical analysis was performed using paired -test, independent -test, one-way ANOVA test, and Tukey's test using SPSS 11.0 program (SPSS Inc., Chicago, IL, USA) for windows.
The statistical analysis showed a significant difference in the clinical evaluation of POS at 24 h interval among three groups (Cention N, Activa™ Bioactive Restorative, Equia forte). However, following 1 week and 1 month, there is no significant difference in Group C (Activa™ Bioactive Restorative).
POS was seen more in Cention N contrast to Equia forte and Activa™ bioactive restorative material.
比较三种大块充填修复材料（Cention N、Equia Forte、Activa™生物活性修复材料）用于Ⅰ类后牙修复时的术后敏感性（POS）。
随机选取144例患有咬合面龋的患者并分为三组。制备标准化的Ⅰ类洞型，并用Cention N、Equia forte和Activa™生物活性修复材料进行修复。使用标准化冷测试和用空气注射器吹气进行空气刺激来评估修复后牙齿的POS。使用视觉模拟量表，每隔24小时、1周和1个月评估患者的反应。使用SPSS 11.0程序（美国伊利诺伊州芝加哥市SPSS公司）对Windows系统进行配对检验、独立检验、单因素方差分析和Tukey检验进行统计分析。
统计分析显示，三组（Cention N、Activa™生物活性修复材料、Equia forte）在术后24小时间隔的POS临床评估上存在显著差异。然而，在1周和1个月后，C组（Activa™生物活性修复材料）没有显著差异。
与Equia forte和Activa™生物活性修复材料相比，Cention N的术后敏感性更高。
