摘要:

目的 观察Er:YAG激光用于年轻恒切牙活髓切断术的临床效果。方法外伤冠折露髓年轻恒切牙40颗,随机分为2组,每组20颗。激光组用Er:YAG激光行活髓切断和三氧化物多聚体(mineral trioxide aggregate,MTA)直接盖髓,常规组用常规方法行活髓切断和MTA直接盖髓,随访12个月并进行临床评价。结果激光组成功19颗,失败1颗,成功率95%;常规组成功18颗,失败2颗,成功率90%;2组成功率差异无统计学意义(χ 2=0.367,P=0.545)。 结论 对年轻恒切牙应用Er:YAG激光进行活髓切断和MTA直接盖髓保存牙髓活力的近期效果良好。

Abstract:

Objective To observe the clinical effect of Er:YAG laser for pulpotomy in young permanent incisors.Methods 40 young permanent incisors with xeposed pulp were divided into 2 groups respectively. Teeth in laser group were treated with mineral trioxide aggregate combined with Er:YAG laser for pulpotomy with teeth in control group were treated with mineral trioxide aggregate (MTA) pulpotomy only. Patients were scheduled for follow-up after 1, 3, 6, 12 months to undergo clinical and radiographic examination.Results 18 of the treated teeth in control group and 19 of the treated teeth in laser group showed no clinical or radiographic signs of failure during the follow-up period. There was no significant difference between the two groups.Conclusion Pulpotomy with Er:YAG laser and direct capping with MTA was a successful and effective treatment for pulp exposure in young permanent incisors.

Key words: Er:YAG laser, Young permanent incisors, Crown fracture, MTA, Pulpotomy
