The bond strength (BS) and failure status of demineralized dentin following the application of chitosan solution and chlorhexidine (CHX) is of interest to dentists. A total of 30 non-pathological extracted premolar teeth were subjected to caries induction through the pH cycle procedure. The teeth were divided equally into 3 groups as such as group I: control (distilled water), Group II-2.5% chitosan solution and Group III - chlorhexidine (CHX). Later teeth were subjected to a microtensile bond strength test (µTBS). The failure mode was assessed using stereo microscope. The bond strength of the chitosan-treated specimens was significantly higher than that of the chlorhexidine treated specimens and the control specimen which had the lowest bond strength.
壳聚糖溶液和洗必泰（CHX）应用后脱矿牙本质的粘结强度（BS）和失败状态是牙医感兴趣的。总共30颗非病理性拔除的前磨牙通过pH循环程序进行龋病诱导。牙齿被平均分为3组，即：第一组：对照组（蒸馏水），第二组 - 2.5%壳聚糖溶液，第三组 - 洗必泰（CHX）。随后对牙齿进行微拉伸粘结强度测试（µTBS）。使用立体显微镜评估失败模式。壳聚糖处理标本的粘结强度显著高于洗必泰处理标本和粘结强度最低的对照标本。
