Abstract

Context: Adhesion to dentin remains a tough challenge due to its heterogeneous composition, complex histologic structure and high tubular content, warranting the need to investigate methods to improve the bond strength of the commonly used access restorative materials to pulp chamber dentin.

Aims: To evaluate the effect of dentin biomodification using 6.5% grape seed extract and a 980 nm diode LASER on the shear bond strength of resin-based bonded restoration to pulp chamber dentin.

Methods and materials: Access cavities were prepared in 42 extracted human maxillary premolars, which were then sectioned in a buccolingual direction. The samples were serially immersed in 5.25% NaOCl for 40 minutes and 17% EDTA for 3 minutes and allocated into three groups: the control group, the group pre-treated with 6.5% grape seed extract (GSE) and the group pre-treated with a 980 nm diode light amplification by stimulated emission of radiation (LASER). All the samples were restored with resin composites and subjected to shear bond strength testing using a universal testing machine.

Statistical analysis used: Statistical analysis was done using SPSS version 23 software.

Results: The mean shear bond strength was highest in the group pre-treated with GSE, followed by that pre-treated with diode LASER and finally in the control group.

Conclusions: Dentin biomodification using both chemical and physical agents such as grape seed extract and diode LASER was shown to improve the shear bond strength of resin composite endodontic access restorations to the pulp chamber dentin.

新型生物改性策略对牙髓腔牙本质粘接的影响 - 体外研究。
背景:目的:评估使用 6.5% 葡萄籽提取物和 980 纳米二极管激光对牙本质进行生物改性对树脂基粘结修复体与牙髓腔牙本质的剪切粘结强度的影响:在 42 颗拔出的人类上颌前磨牙上制备入路腔,然后沿颊舌方向将其切片。将样品依次浸泡在 5.25% NaOCl 溶液中 40 分钟和 17% EDTA 溶液中 3 分钟,并将其分为三组:对照组、用 6.5% 葡萄籽提取物(GSE)预处理组和用 980 纳米二极管受激辐射光放大(LASER)预处理组。所有样品都用树脂复合材料进行了修复,并使用万能试验机进行了剪切粘接强度测试:统计分析:使用 SPSS 23 版软件进行统计分析:结果:使用 GSE 进行预处理的组的平均剪切粘接强度最高,其次是使用二极管激光进行预处理的组,最后是对照组:使用化学和物理药剂(如葡萄籽提取物和二极管激光)进行牙本质生物改性可提高树脂复合牙髓通路修复体与髓室牙本质的剪切粘接强度。
