目的：观察Nd:YAG激光照射后光敏窝沟 封闭剂封闭，治疗中老年人早期根面龋的临床 效果。方法：用脉冲Nd:YAG激光照射龋损区，然后用光敏窝沟封闭 剂封闭，定期复查。结果 ：治疗组83例早期根面龋齿中，成功69例，有效11例，失败3例，疗效明显优于对照组。结论：Nd:YAG激光照射后用窝沟封闭剂封闭对早期根面龋有较好的疗效。%AIM: To observe the treatment effects of seale d after irradiation with pulsed Nd:YAG laser for early root surface caries. METHOD: The root surface caries is irradiated by pulsed Nd:YAG laser, then s ealed with light-cured sealant. RESULTS: In 83 cases of c ario us tooth of the treatment group, the success rate, effective rate and fail ure rate we re 83.13%, 13.25% and 3.61%, respectively. The effects of the treatment group w as much bette r than the control group(P<0.01). CONCLUSION: The study in dicated that the light cured sealant sealed after Nd:YAG laser irradiation was a good theraputic method for early root-surface caries.
