摘要:

目的:评估Er:YAG激光联合氢氧化钙制剂在年轻恒牙间接盖髓中的疗效。方法:将126例患者(男49例,女77例,14~16岁,189颗牙)的患深龋下颌第1磨牙随机分为Er:YAG激光组、氢氧化钙组和Er:YAG联合氢氧化钙组。分别用Er:YAG激光、氢氧化钙及两者联合处理龋洞,并分别在治疗后1周、6个月、12个月对患牙进行临床及X线片检查,根据成功标准统计成功、失败例数。结果:治疗后1周及6个月,3组间接盖髓成功率比较差异无统计学意义(P>0.05);术后12个月,3组间接盖髓成功率比较差异有统计学意义(P <0.05),且成功率由高到底分别为Er:YAG激光组联合氢氧化钙组、Er:YAG激光组、氢氧化钙组。结论:Er:YAG激光联合氢氧化钙在年轻恒牙深龋间接盖髓治疗中的远期疗效良好,并能够有效降低牙髓炎及根尖周炎的发生率。

Objective:To evaluate curative outcomes of Er:YAG laser conbined with calcium hydroxide in indirect pulp treatment for young permanent teeth. Methods:A total of 126 patients with deep caries of mandibular first permanent molars (49 men and 77 female, the range of age was from 14 to 16 years old, and 189 teeth) were randomly divided into Ca(OH)2 group, Er:YAG laser group and Er:YAG laser conbined with Ca(OH)2 group. The cavities were treated with calcium hydroxide, Er:YAG laser or both of them, respectivly.All patients were visited at 1 week, 6 months, 12 months after the treatment for clinical and X-ray examination. Results:After 1 week and 6 month follow-up, the success rate of indirect pulp treatment among the three groups had no statistical significance (P>0.05). After 12 month follow up, the success rate of indirect pulp treatment among the three groups had statistical significance (P<0.05) and the order of success rate from high to bottom was Er:YAG Laser conbined with Ca(OH)2 group, Er:YAG laser group, and Ca(OH)2 group. Conclusion:Combination of Er:YAG laser and calcium hydroxide can achieve better long-term outcomes for indirect pulp capping on young permanent teeth with deep carious lesions and reduce the incidence of pulpitis and periapical disease effectively.
