I studied the effect of chlorhexidine incorporation into experimental dentin adhesives with different hydrophilicities on the chlorhexidine release and the microtensile bond strength to dentin after 24 h and 14 months after specimen preparation. The more chlorhexidine released the more hydrophilic resin co-monomers. Significant reduction in bond strength was observed in all adhesive groups, except for chlorhexidine-containing most hydrophobic adhesive. Also, MMA-based resin was used to measure chlorhexidine-release from resin cement by means of HPLC, and antibacterial effect against Streptococcus mutans and Enterococcus faecalis. The 3.0 and 4.0% chlorhexidine-incorporated cement exhibited chlorhexidine release for 5 weeks; however, more than 98% of chlorhexidine was retained in resin matrix. The 3.0 and 4.0% chlorhexidine-incorporated resin cement possessed prolonged chlorhexidine release and antibacterial properties for 2 weeks.

研究了不同亲水性的牙本质粘结剂中加入洗必泰对洗必泰释放量和试件制备后24小时和14个月牙本质微拉伸强度的影响。洗必泰释放越多，亲水性树脂共聚单体越多。除了含有最疏水的洗必泰的粘结剂外，所有粘结剂组的粘接强度都显著降低。用高效液相色谱法测定了MMA树脂的洗必泰释放量，以及对变形链球菌和粪肠球菌的抑菌效果。3.0%和4.0%的洗必泰粘固剂在5周内有洗必泰的释放，但仍有98%以上的洗必泰保留在树脂基质中。3.0%和4.0%的洗必泰树脂水门汀具有较长的洗必泰释放时间和2周的抗菌性能。
