The aim of this retrospective study was to analyze the occurrence and characteristics of pre-eruptive intracoronal resorptions in a clinical orthodontic patient population.
Patients treated in an orthodontic department (University of Pécs, Pécs, Hungary) were included. Unerupted teeth on panoramic radiographs were analyzed for intracoronal radiolucent lesions. For each patient, the demographic data, jaw localization, number of unerupted teeth with pre-eruptive intracoronal resorption lesions, number of lesions per tooth, size and localization of pre-eruptive intracoronal resorption defects, affected tooth's surface, pulp involvement and ectopic position of the tooth with defects were recorded.
In the 3,143 patients investigated, 55 teeth in 49 patients showed pre-eruptive intracoronal resorption lesions (subject incidence: 1.56%). The incidence on unerupted teeth was 0.25%. Pre-eruptive intracoronal resorption was significantly more common in mandibles (43 mandibular vs. 12 maxillary lesions) with an odds ratio of 12.84 (95% Confidence Interval: 5.19-31.74) and no gender differences were found (p = 0.746). The occurrence of pre-eruptive intracoronal resorption was highest in the youngest (7-10 years) mixed dentition status group (p < 0.001). Most of the lesions (44 of 55, or 80.0%) were localized in the dentin, occupying two-third or less of the dentin thickness. Only 12.73% (7/55) of the lesions were not localized on the occlusal surface. Of the lesions, 89.1% (49/55) showed no obvious size increase over an average follow-up of 36.4 ± 8.1 months.
Pre-eruptive intracoronal resorption may occur mainly in the mixed dentition stage in orthodontic patients. Careful and attentive radiographic evaluations may facilitate early detection and follow-up of the lesions' possible dimensional changes, especially when resorption influences orthodontic extraction therapy.
本回顾性研究旨在分析临床正畸患者群体中萌出前牙内吸收的发生率及特征。
纳入在匈牙利佩奇大学正畸科接受治疗的患者。对全景X线片上未萌出的牙齿进行牙内透射性病变分析。记录每位患者的人口统计学数据、颌骨定位、存在萌出前牙内吸收病变的未萌出牙齿数量、每颗牙齿的病变数量、萌出前牙内吸收缺损的大小和定位、患牙表面、牙髓受累情况以及有缺损牙齿的异位位置。
在3143例接受调查的患者中，49例患者的55颗牙齿出现萌出前牙内吸收病变（患者发病率：1.56%）。未萌出牙齿的发病率为0.25%。萌出前牙内吸收在下颌骨中明显更为常见（下颌病变43例，上颌病变12例），优势比为12.84（95%置信区间：5.19 - 31.74），未发现性别差异（p = 0.746）。萌出前牙内吸收的发生率在最年轻（7 - 10岁）的混合牙列状态组中最高（p < 0.001）。大多数病变（55例中的44例，即80.0%）位于牙本质，占据牙本质厚度的三分之二或更少。只有12.73%（7/55）的病变不在咬合面上。在平均36.4 ± 8.1个月的随访中，89.1%（49/55）的病变没有明显的大小增加。
萌出前牙内吸收可能主要发生在正畸患者的混合牙列阶段。仔细且专注的影像学评估可能有助于早期发现病变并跟踪其可能的尺寸变化，尤其是当吸收影响正畸拔牙治疗时。
