外伤脱位牙再植后的临床疗效分析

摘要

AIM: To analyze the factors influencing the effects of tooth replantation of avulsed permanent teeth.METHODS : Twenty-six children with 32 avulsed permantent teeth were enrolled in this study.The avulsed permantent teeth were replantated in the Department of Pediatric Dentistry, Jining Stomatology Hospital, in the years between 2004 and 2008.The patients were followed up regularly for 2 to 3 years.RESULTS : During the follow-up period, periodontal ligament healing was observed in 4/32, replacement resorption in 23/32, inflammatory resorption in 3/32 and odontoptosis in 2/32 teeth.The success rate of replatation was 84.37％.CONCLUSION: The replantation of young permanent teeth showed a higher success rate.The success of replantation was related to ex vivo time,storage medium and root development stage of the avulsed teeth.%目的:研究探讨影响再植牙临床疗效的相关因素.方法:对2004-2008到我院儿童牙病科就诊的26例8～14岁患儿32个外伤牙进行常规再植,术后定期复查,观察时间2～3年.结果:观察期内,32个外伤恒牙中牙周膜愈合4个,替代性吸收23个,炎症性吸收3个,松动脱落2个.成功率为84.37%.结论:年轻恒牙再植后的成功率较高,但与脱位牙离体时间、保存方式及牙根的发育程度等因素有密切关系.
