Abstract
A detailed radiographic study of 46 cases of maxillary incisor resorption related to unerupted cuspids finds most resorption in midroot, with about half on labial or lingual surfaces where it was not detectable on periapical radiographs. Resorption appears early, making it desirable to evaluate cuspid position no later than 10 or 11 years of age.
摘要
一项针对46例与未萌出尖牙相关的上颌切牙吸收病例的详细影像学研究发现，大多数吸收发生在牙根中部，约一半发生在唇面或舌面，而根尖片上无法检测到。吸收出现得较早，因此最好在10或11岁之前评估尖牙位置。
