Abstract

Background/aim: Avulsion injuries have an uncertain prognosis. This study aims to evaluate periodontal ligament healing patterns and factors affecting the survival of replanted avulsed teeth.

Materials and methods: In this retrospective study, data from 204 avulsed teeth in 143 children (mean age: 9.6 ± 2 years) who sustained avulsion injuries were reviewed. Primary teeth, non-replanted permanent teeth, and cases with follow-up shorter than 60 days were excluded. Data analysis included 60 replanted permanent teeth from 41 patients (18 girls and 23 boys), with a follow-up period ranging from 2 to 147 months. Collected data covered age, gender, extra-alveolar storage time, root development stage, and periodontal ligament healing patterns. Statistical analysis was performed on the data.

Results: Avulsion injuries predominantly occurred during outdoor activities (n = 22, 59.5%), followed by school (n = 10, 27%) and home (n = 5, 13.5%). The main causes were falls (n = 20, 50%), bicycle accidents (n = 6, 15%), sports injuries (n = 5, 12.5%), traffic accidents (n = 2, 5%), and violence (n = 1, 2.5%). Among replanted teeth, 51.7% were immature. Treatments included root canal therapy (n = 30, 50%), apexification (n = 12, 20%), and regeneration (n = 2, 3.3%), while 16 teeth received no treatment. Inflammatory resorption was not observed in teeth replanted within 1 h of injury (8.4%). Functional healing/ankylosis was observed in 14 (23.3%) of the replanted teeth, replacement resorption in 40 (66.7%), and inflammatory resorption in 6 (10%). Replacement resorption affected 66.7% of the replanted teeth, with 62.5% lost over time. Functional healing/ankylosis was more common in mature teeth, while inflammatory resorption was higher in immature teeth. According to Kaplan-Meier estimated survival curves, the survival rate during the 5-year observation period was 47.5%. Survival times were longer in boys and in mature teeth (p < 0.05).

Conclusions: Gender and root development stages were observed to significantly impact the prognosis of replanted avulsed teeth.

撕脱牙的长期临床和影像学预后评估：回顾性研究。

背景/目的：撕脱伤预后不确定。本研究旨在探讨牙周韧带的愈合模式及影响脱脱牙再植后存活的因素。材料与方法：回顾性分析143例（平均年龄：9.6±2岁）发生撕脱伤的儿童204颗牙齿的资料。排除乳牙、非再植恒牙及随访时间短于60天的病例。资料分析包括41例患者（女孩18例，男孩23例）的60颗再植恒牙，随访时间2 ~ 147个月。收集的数据包括年龄、性别、牙槽外储存时间、牙根发育阶段和牙周韧带愈合模式。对数据进行统计分析。结果：撕脱伤主要发生在户外活动（n = 22, 59.5%），其次是学校（n = 10, 27%）和家庭（n = 5, 13.5%）。主要原因为跌倒（n = 20, 50%）、自行车事故（n = 6, 15%）、运动损伤（n = 5, 12.5%）、交通事故（n = 2.5, 5%）和暴力（n = 1, 2.5%）。再植牙中未成熟的占51.7%。治疗包括根管治疗（n = 30, 50%）、根尖治疗（n = 12, 20%）和再生（n = 2, 3.3%）， 16颗牙未接受治疗。损伤后1 h内再植牙无炎症吸收（8.4%）。功能愈合/强直14例（23.3%），替代吸收40例（66.7%），炎症吸收6例（10%）。66.7%的再植牙受替代吸收影响，62.5%随时间流失。功能愈合/强直在成熟牙齿中更常见，而炎症吸收在未成熟牙齿中更高。根据Kaplan-Meier估计生存曲线，5年观察期间生存率为47.5%。结论：性别和牙根发育阶段对脱脱牙再植的预后有显著影响。
