Abstract

Objective: The objective of this study was to evaluate external apical root resorption (EARR) in cases with extraction and non-extraction fixed orthodontic treatment.

Methods: Ninety subjects were included in this study. The patients were divided into two groups: 43 with extraction treatment and 47 with non-extraction orthodontic treatment. EARR was measured using the crown-to-root ratio of the maxillary and mandibular incisors and canines on panoramic radiographs taken at the beginning (T0) and end of the treatment (T1). The Bonferroni corrected Z test was used for multiple comparisons.

Results: There were 24 (55.8%) individuals in the extraction group and 12 (25.5%) in the non-extraction group, with a minimum of one tooth with severe resorption. There was no resorption in 0% of individuals in the extraction group and five (10.6%) individuals in the non-extraction group. There was a statistically significant correlation between the groups and the degree of resorption (p = 0.008). When the maxillary and mandibular teeth in the extraction group were compared, a significant difference was found in all degrees of resorption except for mild resorption.

Conclusions: There was a significant difference in EARR between the extraction and non-extraction treatment groups, with maxillary incisors showing more resorption in the extraction treatment.

评估拔牙和非拔牙固定正畸治疗病例的根尖外吸收。

研究目的本研究旨在评估拔牙和非拔牙固定正畸治疗病例的根尖外吸收（EARR）情况：本研究共纳入 90 名受试者。方法：本研究共纳入 90 名受试者，将其分为两组：43 名接受拔牙治疗，47 名接受非拔牙矫正治疗。在治疗开始（T0）和结束（T1）时拍摄的全景照片上，使用上下颌切牙和犬齿的冠根比来测量 EARR。多重比较采用 Bonferroni 校正 Z 检验：拔牙组有 24 人（55.8%），非拔牙组有 12 人（25.5%），其中至少有一颗牙齿严重吸收。拔牙组中有 0% 的牙齿没有吸收，非拔牙组中有 5 个牙齿（10.6%）没有吸收。拔牙组与牙齿吸收程度之间存在统计学意义上的显著相关性（p = 0.008）。将拔牙组的上颌牙和下颌牙进行比较，发现除轻度吸收外，其他吸收程度均有显著差异：结论：拔牙治疗组和非拔牙治疗组的 EARR 有明显差异，拔牙治疗组的上颌切牙吸收更多。
