目的:观察氟斑牙经脉冲Nd-YAG激光照射后充填微渗漏的发生情况,为相关研究提供参考。方法:选取人体因各种原因而
拔除的氟斑牙(重度)30颗,分成A、B 两组。A 组为Nd: YAG 激光消除龋坏组织作为实验组,B组用传统涡轮钻去龋作为对照组。
所有牙齿用树脂充填,经冷热循环处理后,再进行微渗漏观察。结果:实验组充填体边缘微渗漏比对照组明显低(P<0.01)。结论:脉
冲Nd: YAG激光去除氟斑牙坏死组织有助于增强充填物与釉质连接,不增加微渗漏,有助于充填成功。 |

Objective:To observe the microleakage after removal of caries of mottled teeth with pulse Nd:YAG laser in order to
make a reference to the related research.Methods:30 thirty extracted mottled enamel of patients with stomatological disease were
selected and randomly divided into two groups, namely, the group A and group B. The decayed enamel in the experimental group were
removed by the pulse Nd:YAG laser, while in the control group were removed by drilling. All the teeth were filled with resin after the
removal of caries. Then the filled teeth were investigated by microleakage experiment.Results:Statistically significant differences in
amount of dye infiltration were found between the two groups (P<0.01).Conclusion:It is implied that the removal of caries of Mottled
enamel with pulse Nd: YAG laser enhanced the bonding of resin to enamel which could reduce the filling microleakage and improve the
restoration. |
