Abstract

The antibacterial effect restorative materials is important for obtaining good prognosis. The purpose of this study was to evaluate the antibacterial effect of trial composite resins which were made with Clearfil SC II and antibacterial powder as a filler. Four kinds of antibacterial powder were used: two kinds of Cellewall; far infrared radiating ceramic materials YYT 1 and YYT 1A, Bactekiller; antibacterial zeolite and Zeomic; zeolite with antibacterial ion were mixed with Clearfil SC II at the content of 5, 10, 15, 20, 30, 40, 50 wt %. Cariogenic bacteria Streptococcus mutans Ingbritt, was used in this experiment. Disks were placed in petri dishes and the width of inhibitory zone was evaluated after 24 hours. In order to evaluate the effect of saline solution, the disks were stored in saline solution for 24 and 48 hours and the inhibitory zone were also evaluated same condition. The conclusion is that the new composite resins containing Zeomic had a strong antibacterial effect against S. mutans and this effect of Zeomic was not reduced after storage in saline solution.

含抗菌填料复合树脂的细菌学和力学评价
修复材料的抗菌效果是获得良好预后的重要因素。本研究的目的是评价以Clearfil SC II和抗菌粉为填料制备的复合树脂的抗菌效果。采用四种抗菌粉剂:两种celllewall;远红外辐射陶瓷材料yyt1和YYT 1A,抗菌剂;抗菌沸石和Zeomic;含抗菌离子的沸石与Clearfil SC II分别以5、10、15、20、30、40、50 wt %的比例混合。本实验采用致龋菌英氏变形链球菌。将培养皿置于培养皿中,24小时后评估抑菌带宽度。为了评估生理盐水的效果,将培养皿在生理盐水中保存24和48小时,并在相同的条件下评估抑菌带。综上所述,Zeomic复合树脂对变形链球菌具有较强的抑菌作用,且Zeomic在生理盐水中保存后其抑菌作用不降低。
