| 摘 要： | 目的：研究2种铒激光对牙本质小管封闭的效果。方法：制取27个离体牙的牙本质盘，用0．5 mol／L 的 EDTA 脱矿使得牙本质小管开放，按处理方法不同随机分为3组（n ＝9）：空白对照组（A），Er：YAG 激光组（B），Er，Cr：YSGG 激光组（C）。通过扫描电镜（SEM）观察比较3组牙本质小管的封闭效果。结果：SEM观察发现 B、C 组均有明显封闭物堵塞牙本质小管口。小管面积暴露率 A、B、C 组分别为（33．610±7．545）％、（4．186±0．723）％、（3．798％±0．843）％（3组间比较，P ＜0．01；B、C 组间比较，P ＞0．05）。结论：2种铒激光均能较好的封闭牙本质小管，两者的封闭效果无显著差异。

| Abstract: | Objective:To evaluate the occluding effect of 2 kinds of Er laser on dentinal tubules.Methods:27 dentine discs were prepared,etched with 0.5 mol/L EDTA and then divided into 3 groups(n =9).The samples in group A without treatment were used as the controls,in group B treated with Er:YAG laser irradiation and in group C treated with Er,Cr:YSGG laser irradiation.The occluding effect was examined by scanning electron microscopy (SEM).Results:Micrographs of SEMshowed obvious occluding effect in group B and C.The dentinal tubule exposure rates of group A,B and C were 33.61 0% ±7.545%,4.1 86% ±0.723% and 3.798% ± 0.843% respectively(among 3 groups,P <0.01 ;B vs C,P >0.05).Conclusion:The 2 kinds of Er laser can block dentinal tu-bules. |
