【摘要】：目的:从微渗漏角度探究两种脉冲的Er:YAG激光联合自酸蚀粘接剂对于窝沟封闭的影响。方法:50颗离体牙随机分为5组,每组10颗,第1组:传统磷酸蚀刻处理窝沟釉质表面;第2组:MSP(最短脉冲)模式下的激光处理窝沟釉质表面;第3组:MSP+自酸蚀粘接系统处理窝沟釉质表面;第4组:SP(短脉冲)模式下的激光处理窝沟釉质表面;第5组:SP+自酸蚀粘接系统处理窝沟釉质表面。然后对所有组进行封闭剂充填。最后用体视显微镜进行微渗漏的观察。结果:两种脉冲的激光比较,差异无统计学意义(P0.05);对照组与激光组比较,差异有统计学意义(P0.05);对照组与激光+自酸蚀组比较,差异无统计学差异(P0.05)。结论:激光脉冲对窝沟封闭微渗漏无影响,单独使用激光不能代替全酸的作用,但是联合使用自酸蚀粘接系统能达到传统方法的效果,有望应用于临床。
[Abstract]:Objective: from the perspective of micro leakage of two kinds of pulse Er:YAG laser combined with self etching adhesive for pit and fissure sealant effect. Methods: 50 teeth were randomly divided into 5 groups, 10 in each, first groups: traditional phosphate etching fissure enamel surface; second groups: MSP (shortest pulse processing) fissure enamel surface laser mode; the third group: MSP+ self etching adhesive system processing fissure enamel surface; fourth groups: SP (pulse) treatment of fissure enamel surface laser mode; the fifth group: SP+ self etching adhesive system of fissure enamel surface. Then all groups were filling sealer at last, stereomicroscope observation microleakage. Results: comparison of two kinds of pulse laser, the difference was not statistically significant (P0.05); control group and laser group, the difference was statistically significant (P0.05); control group with laser + self etching group were compared, the difference was not statistically different (P0.05). Conclusion: laser pulse has no effect on microleakage of pit and fissure sealant. Laser alone can not replace the effect of total acid. However, the combination of self etching and bonding system can achieve the effect of traditional methods, and is expected to be applied in clinic.

【正文快照】： 0引言牙齿中的大部分龋坏发生在窝沟,Gooch[1]等认为窝沟龋占据所有龋坏的90%,因为窝沟的解剖形态导致菌斑的快速堆积,且不易被清理[2]。窝沟封闭是目前预防龋齿中最有效的措施,它的优点包括促进龋坏的再矿化、阻止菌斑在窝沟中形成、避免食物残渣在窝沟中堆积[3]。封闭剂是否
