This study was done to compare and evaluate the compressive strength, diametral tensile strength, and microleakage of glass ionomer cement and chlorhexidine-modified glass ionomer cement. The glass ionomer cements used in the study were Fuji IX for group I and chlorhexidine-modified glass ionomer cement for group II.
The strength characteristics (compressive and diametral tensile strengths) and microleakage of both the groups were evaluated after 24 h. Student's "t" test and Mann-Whitney test were used for statistical analysis of the difference in strength characteristics and microleakage.
There was no statistical difference (P>0.05) in the strength characteristics and microleakage of glass ionomer cement and chlorhexidine-modified glass ionomer cement.
The present study suggests that strength characteristics and marginal sealing capability of chlorhexidine-modified glass ionomer cement were similar to those of glass ionomer cement (Fuji IX). So, chlorhexidine-modified glass ionomer can be considered as a substitute for glass ionomer cements, especially in pediatric dentistry.
本研究旨在比较和评估玻璃离子水门汀与洗必泰改性玻璃离子水门汀的抗压强度、径向拉伸强度和微渗漏情况。研究中使用的玻璃离子水门汀，第一组为富士IX，第二组为洗必泰改性玻璃离子水门汀。
24小时后评估两组材料的强度特性（抗压强度和径向拉伸强度）及微渗漏情况。采用学生“t”检验和曼-惠特尼检验对强度特性和微渗漏的差异进行统计学分析。
玻璃离子水门汀与洗必泰改性玻璃离子水门汀在强度特性和微渗漏方面无统计学差异（P>0.05）。
本研究表明，洗必泰改性玻璃离子水门汀的强度特性和边缘封闭能力与玻璃离子水门汀（富士IX）相似。因此，洗必泰改性玻璃离子水门汀可被视为玻璃离子水门汀的替代品，尤其是在儿童牙科领域。
