Tooth root resorption is often incidentally revealed on radiographic examination. Here, we report a case of root resorption in multiple teeth of unknown etiology. Radiographic examination revealed root resorption in the cervical region of the left lateral incisor, canine, first and second premolars, and first and second molars of the mandible. Panoramic radiographs revealed no mandibular lesions that could cause tooth resorption. The patient did not wish to undergo any treatment and is currently under observation. Tooth root resorption with unknown etiology is rare, and further case collection is needed to determine the cause and treatment.展开更多

The etiology of apical root resorption is multifactorial but largely depends upon the type of orthodontic tooth movement and treatment duration. Study Objective: The primary aim of this study is to examine the association of external apical root resorption and vertical correction in anterior open bite malocclusions using panoramic radiographs for evaluation. Materials and Methods: Pre-treatment and post-treatment panoramic radiographs of 16 patients with anterior open bite malocclusions were scored to assess root resorption of anterior teeth (U/L 3-3). Initial and final root length and total tooth length for U/L 3-3 were measured on panoramic radiographs in Dolphin imaging. Results: Of the 24 pairs of measurements, 7 had a significant p-value (p Conclusions: A statistically significant amount of root resorption was observed, from pre-treatment to post-treatment radiographs. All mandibular anterior teeth except the mandibular right lateral incisors showed evidence of root resorption.展开更多
