Abstract

Background/Aims

Dental trauma resulting in tooth intrusion is a severe injury of permanent dentition, with a prevalence of 0.5%–1.9% among traumatic dental injuries. Currently, treatment guidelines for intruded permanent teeth depend on root development and the degree of intrusion. However, the categorization of tooth maturity as mature or immature simplifies a complex continuum of root development stages. This study aims to investigate the impact of various stages of root development on the success of spontaneous re-eruption (SRE) of intruded teeth.

Materials and Methods

This retrospective study analysed data from 80 children (125 teeth) aged 6–12 years who experienced dental intrusion between 2018 and 2022. Root maturation was classified based on Cvek's classification, eight were categorized as stage 1, 29 as stage 2, 44 as stage 3, 25 as stage 4, and 19 as stage 5. Intruded teeth with immature roots (Cvek's class 1–4) underwent SRE, while mature teeth (Cvek's class 5) were treated with SRE, orthodontic repositioning, or surgical repositioning based on the degree of intrusion. Primary outcome measures were successful re-eruption and secondary outcomes included observed complications during follow-up.

Results

Regression analysis revealed that the patient's age, degree of root maturation, and degree of intrusion significantly affected spontaneous re-eruption (p < .05). SRE was more successful in teeth with Cvek's stages 1 and 2 compared to stages 3 and 4. Complications were associated with the treatment method, degree of root immaturity, and degree of intrusion.

Conclusion

The study demonstrates that as root maturation progresses, the likelihood of re-eruption decreases, and the risk of pulp necrosis and infection increases. Therefore, teeth in later stages of immaturity (Cvek stage 4) should be repositioned orthodontically or surgically without waiting for spontaneous re-eruption.

牙根不成熟和侵入深度对自发再萌发和愈合并发症的影响：回顾性分析

背景/目的：牙齿外伤导致的牙齿内陷是恒牙的一种严重损伤，在牙齿外伤中的发病率为 0.5%-1.9%。目前，恒牙内陷的治疗指南取决于牙根发育和内陷程度。然而，将牙齿成熟度分为成熟和不成熟，简化了牙根发育阶段的复杂连续性。本研究旨在探讨牙根发育的不同阶段对入侵牙齿自发再萌出（SRE）成功率的影响：这项回顾性研究分析了 2018 年至 2022 年期间经历过牙齿入侵的 80 名 6-12 岁儿童（125 颗牙齿）的数据。根据 Cvek 的分类法对牙根成熟度进行了分类，8 个被归为第一阶段，29 个被归为第二阶段，44 个被归为第三阶段，25 个被归为第四阶段，19 个被归为第五阶段。牙根不成熟的入侵牙齿（Cvek 分级 1-4）接受 SRE 治疗，而成熟牙齿（Cvek 分级 5）则根据入侵程度接受 SRE、正畸复位或手术复位治疗。主要结果指标为成功复萌，次要结果包括随访期间观察到的并发症：回归分析表明，患者的年龄、牙根成熟度和内侵程度对自发再萌出有显著影响（p 结论：该研究表明，随着牙根成熟度的增加，自发再萌出的成功率也会增加：该研究表明，随着牙根成熟度的增加，再萌出的可能性降低，而牙髓坏死和感染的风险增加。因此，处于不成熟后期（Cvek 第 4 期）的牙齿应通过正畸或手术重新定位，而不必等待自发再萌出。
