目前的活体研究评价了牙本质混合层在深(牙合)面树脂复合修复体中的降解。作为正畸治疗的一部分，计划拔除的无龋前磨牙被准备并修复，然后在12个月后拔除。使用的粘合剂是一种单瓶酸洗丙酮产品(Prime&Bond NT，Dentsply/Culk)。对照组(n=8)按厂家说明书进行修复，实验组在酸蚀、漂洗后涂抹2%的洗必泰溶液，涂抹粘结剂前。12个月后，对照组所有牙齿均出现广泛降解，而实验组未见降解。体外测试表明，对照组和实验粘接剂之间的即时微拉伸粘接强度没有显著差异。
The current in vivo study evaluated the degradation of dentin hybrid layers in deep occlusal-surface resin composite restorations using TEM. Caries-free premolars scheduled for extraction as part of orthodontic treatment were prepared and restored, then extracted after 12 months. The adhesive used was a single-bottle etch-and-rinse acetone-based product (Prime & Bond NT, Dentsply/Caulk). Control group restorations (n=8) were placed according to the manufacturer's instructions, while the experimental group received application of a 2% solution of chlorhexidine digluconate after etching and rinsing and prior to application of the adhesive. Extensive degradation was observed in all of the teeth in the control group after 12 months, while no degradation was observed in the experimental group. In vitro testing showed no significant difference in immediate microtensile bond strength between the control and experimental adhesive protocols.
