Abstract

Purpose: The aim of this study was to investigate the potential for pulp revascularization in relation to patient age at the time of injury following luxation injury of mature anterior permanent teeth.

Materials and methods: A total of 93 teeth from 70 patients were included. The patients were divided into subgroups based on their age at the time of the injury.

Statistics: the Aalen-Johansen method was used to estimate the risks of pulp canal obliteration (PCO) and pulp necrosis (PN). The absolute 2 year risks of PCO and PN were obtained with cause-specific Cox regression and reported separately for each cohort, standardised to age at injury and degree of repositioning.

Results: For the group younger than 15 years of age, the risk of PN after 12 months was 62.3% [95% CI 44.9; 79.7] in the cohort from 1972 to 1980 and 28.6% [95% CI 4.9; 52.2] in the cohort from 2012 to 2020. For the age group 16-20 years, the risk of PN after 12 months was 66.7 [95% CI 40.0;93.3] in the cohort from 1972 to 1980 and 25% [95% CI 0.0;55.0] in the cohort from 2012 to 2020. For the age group between 21 and 25, the risk of PN after 12 months was 66.7% [95% CI 40.0; 93.3] in the cohort from 1972 to 1980 and 55.6% [95% CI 23.1; 88.0] in the cohort from 2012 to 2020.

Conclusion: There is potential for pulp revascularization in mature anterior teeth with lateral luxation in patients up to 25 years of age. The risk of PN appears to increase with age.

成熟前牙侧向脱位牙髓血管再造的可能性与患者受伤时的年龄有关--一项回顾性队列研究。

目的：本研究旨在探讨成熟前恒牙松动损伤后牙髓再血管化的可能性与损伤时患者年龄的关系：共纳入 70 名患者的 93 颗牙齿。统计：采用Aalen-Johansen法估算牙髓管阻塞（PCO）和牙髓坏死（PN）的风险。根据受伤时的年龄和复位程度标准化后，通过特定原因的 Cox 回归得出 PCO 和 PN 的 2 年绝对风险，并分别报告每个队列的情况：对于 15 岁以下年龄组，1972 年至 1980 年队列中 12 个月后发生 PN 的风险为 62.3% [95% CI 44.9; 79.7]，而 2012 年至 2020 年队列中发生 PN 的风险为 28.6% [95% CI 4.9; 52.2]。对于 16-20 岁年龄组，1972-1980 年队列中 12 个月后发生 PN 的风险为 66.7 [95% CI 40.0;93.3]，而 2012-2020 年队列中发生 PN 的风险为 25% [95% CI 0.0;55.0]。在21至25岁年龄组中，1972至1980年队列中12个月后发生PN的风险为66.7% [95% CI 40.0; 93.3]，2012至2020年队列中发生PN的风险为55.6% [95% CI 23.1; 88.0]：结论：25岁以下患者的成熟前牙侧向移位可能导致牙髓血管再通。发生牙髓再血管化的风险似乎随着年龄的增长而增加。

期刊介绍： The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
