Despite recent advances in restorative dentistry adhesive restorations may cause postoperative sensitivity which leads to restoration failure.
This study aimed to compare and evaluate the incremental and bulk fill resin Composite postoperative sensitivity in class II posterior restorations bonded with two adhesive systems (self-etch and etch-and-rinse).
Sixty patients were randomly selected, their age range from twenty-five to forty years old, divided into two groups according to the packing technique of resin composite material; incremental Tetric Evoceram and Tetric Evoceram bulk-fill resin composite. Thirty patients (n = 30) for incremental Tetric Evoceram resin composite restorations and according to the adhesive systems used they were equally divided (n = 15 teeth).Thirty patients (n = 30) for Tetric Evoceram bulk-fill resin composite restorations and according to the adhesive systems used (etch and rinse or self-etch), they were equally divided (n = 15 teeth). Post-operative pain assessed at 24 hours, 1 week and 1 month using the Visual Analog Scale Score (VAS). Each patient was instructed to put a mark on the VAS line at home to point out the intensity of pain at each assessment period. The problem of measuring the pain that pain tolerance of individuals may be different from the others. This may be due to different reasons, and it is not always because of a problem in the restoration.
After 1 day, 1 week as well as 1 month, no statistically significant disagreement between the two resin composite types using self-etch adhesive strategy and total-etch adhesive strategy. Also, when the two adhesive systems were compared using Bulk Fill resin composite and incremental Nano resin composite no statistically significant disagreement between the two adhesive systems after 1 day, 1 week as well as 1 month.
The post-operative hypersensitivity is related to many factors as the procedure of cavity preparation, adhesive approach, and type of resin composite used and placement technique of the resin composite.
尽管牙体修复学最近取得了进展，但粘结修复可能会导致术后敏感，进而导致修复失败。
本研究旨在比较和评估两种粘结系统（自酸蚀和酸蚀冲洗）粘结的Ⅱ类后牙修复中，分层充填树脂复合材料和大块充填树脂复合材料术后敏感情况。
随机选择60例患者，年龄在25至40岁之间，根据树脂复合材料的充填技术分为两组；分层充填的Tetric Evoceram和Tetric Evoceram大块充填树脂复合材料。30例患者（n = 30）采用分层充填的Tetric Evoceram树脂复合材料修复，根据所使用的粘结系统，将其平均分为两组（n = 15颗牙）。30例患者（n = 30）采用Tetric Evoceram大块充填树脂复合材料修复，根据所使用的粘结系统（酸蚀冲洗或自酸蚀），将其平均分为两组（n = 15颗牙）。使用视觉模拟评分法（VAS）在术后24小时、1周和1个月评估术后疼痛。指示每位患者在家中在VAS线上做标记，以指出每个评估期的疼痛强度。测量疼痛的问题在于个体的疼痛耐受性可能彼此不同。这可能有不同的原因，并不总是因为修复存在问题。
在1天、1周以及1个月后，使用自酸蚀粘结策略和全酸蚀粘结策略的两种树脂复合材料类型之间无统计学显著差异。此外，当使用大块充填树脂复合材料和分层充填纳米树脂复合材料比较两种粘结系统时，在1天、1周以及1个月后两种粘结系统之间无统计学显著差异。
术后过敏与许多因素有关，如窝洞预备程序、粘结方法、所使用的树脂复合材料类型以及树脂复合材料的放置技术。
