摘要
目的:探讨氟化钠壳聚糖凝胶促进乳牙釉质早期龋模型再矿化的可行性。方法:乳前牙试件使用乳酸羧甲基纤维素凝胶预处理,制备早期龋模型;早期龋的乳前牙试件随机分成4组(n=6),3组分别进行氟化钠壳聚糖凝胶、壳聚糖空白凝胶、多乐氟处理,1组作为空白对照,处理完成后进行p H循环,SEM、EDS检测循环完成后的试件表面。结果:SEM观察,氟化钠壳聚糖凝胶能更好的保护釉质表层结构不受破坏,而多乐氟和空白对照组,则表现出釉质表层的崩解。同时氟化钠壳聚糖凝胶有更多的矿化物结晶在釉质表面形成。EDS检测钙离子的沉积比例,氟化钠壳聚糖凝胶组明显多于其余各组(P<0.05)。结论:氟化钠壳聚糖凝胶可以提高乳前牙早期龋的再矿化水平。
Objective: To estimate the remineralization of enamel of primary teeth with early caries protreated by NaF-chitosan gel. Methods: Early stage caries was created on anterior primary teeth. The samples were divided into 4 groups randomly( n = 6), and treated by NaF-ehitosan gel, chitosan gel, duraphat and non- treatment( the control) respectively. Then all samples were underwent a 7 days pH cycle. Then samples were tested with SEM and EDS. Data were analyzed with SPSS 19. Results: The SEM data showed that chitosan gel protected the enamel surface from being ruined by erosion. NaF-chitosan gel group showed more mineral crystal formation on the enamel surface. The NaF-chitosan gel group showed more Ca remineralized on the enamel surface. Conclusion: NaF-chitosan gel can increase the remineraliztion of on the anterior primary teeth with early stage caries.
