The study investigated the dento-facial features of a group of 69 children with trauma to the maxillary central incisors in the mixed dentition compared to a control group of 100 children, in order to identify possible "anatomical" factors predisposing to this type of dental trauma. The group with dental trauma showed excessive proclination of upper incisors to the palatal plane (p < 0.001) and increased lower facial height (p < 0.001) as major characteristics associated to dental trauma. The role of early orthodontic treatment in the attenuation of these factors predisposing to traumatic injuries to frontal teeth is stressed.
该研究调查了一组69名处于混合牙列期且上颌中切牙受过外伤的儿童的牙面特征，并与100名儿童组成的对照组进行比较，以确定可能导致此类牙外伤的“解剖学”因素。牙外伤组表现出上颌切牙相对于腭平面过度前倾（p < 0.001）以及面下高度增加（p < 0.001），这些是与牙外伤相关的主要特征。强调了早期正畸治疗在减轻这些易导致前牙外伤的因素方面的作用。
