目前的研究集中在正畸引起的过度的牙根吸收。目的是在这些病例中确定治疗前采集的放射诊断材料的共同形态特征。这份材料由35名丹麦正畸医生提交。研究表明：(1)各种牙齿形态特征，如内陷、牙根长度、牙根形状等，与正畸治疗中的牙根吸收倾向密切相关；(2)牙列异常，特别是牙位异位和畸形，与正畸治疗中的牙根吸收倾向有关；(3)乳牙期的牙列吸收模式与恒牙期的牙根吸收倾向有关；(4)在正畸治疗中，女孩比男孩更容易发生牙根吸收；(5)在正畸治疗过程中，应注意观察髁突变化、牙根吸收和前牙张开咬合之间的联系。此外，在相当数量的患者中，乳牙和恒牙的异常吸收模式的发现是新的观察结果，应该纳入正畸治疗计划。
The present study focuses on orthodontically provoked, excessive root resorption. The purpose was to identify in these cases common morphological features in radiographic diagnostic material taken before treatment. The material was submitted by 35 Danish orthodontists. The goal was to improve the future orthodontic diagnostics of the dentition in order to prevent severe root resorption during treatment.The study indicates that: (1) there is a strong connection between various dental morphological characteristics, such as invagination, length of root, and root shapes, especially taurodontism, and the tendency to root resorption during orthodontic treatment; (2) there is a connection between anomalies in the dentition, particularly ectopia and agenesis, and the tendency to root resorption during orthodontic treatment; (3) there seems to be a connection between the pattern of resorption in the primary dentition and the tendency to root resorption in the permanent dentition following orthodontic treatment; (4) girls are more susceptible to root resorption during orthodontic treatment than boys; (5) one ought to be on the lookout for connections between condylar changes, root resorptions, and anterior open bites in connection with orthodontic treatment.The observation regarding root resorption in dentitions in which invaginations and taurodontic root shapes occur has not previously been reported. Also, the findings of deviant resorption patterns in both the primary and permanent dentitions in a considerable number of patients are new observations, which ought to be incorporated into orthodontic treatment planning.
