External cervical resorption is caused, almost exclusively, by dental trauma - especially those characterized by concussion - and is a dental disease to be diagnosed and treated accurately by endodontists. However, the vast majority of the cases is initially diagnosed by an orthodontist, due to the imaging possibilities in standardized documentations. Among the causes of external cervical resorption, it is common to mistakenly attribute it to orthodontic treatment, traumatic occlusion or even to chronic inflammatory periodontal disease...

The purpose of this article is to present a simple method for determining the optimal sizes of anterior teeth. This is needed because of the frequency of anomalous and missing maxillary lateral incisors. In addition to anomalous and missing incisors, other factors that create challenges for the dentist and orthodontist when designing an esthetic and occlusally sound dentition are attrition, trauma, transposition, erosion, and caries. Optimal esthetics and occlusion require correctly sized teeth in proportion to themselves and the other teeth...

OBJECTIVE: To evaluate the effect of root and bone visibility on orthodontists' perceptions of the quality of treatment simulations. MATERIAL AND METHODS: An online survey was used to present orthodontists with setups generated for 10 patients in two different types of view: with and without bone and roots as modeled from a cone-beam computed tomography (CBCT) scan. The orthodontists were asked to rate the quality of the setups from poor to ideal on a 100-point visual analog scale and, if applicable, to identify features of concern that led them to giving a setup a less-than-ideal rating...

Although orthodontists focus intensively on the diagnosis and treatment of their patients, they pay less attention to post-treatment development and the risk of relapse often caused by the late growth of the arches and bony base. The aim of this study, therefore, was to determine the growth changes, which can affect craniofacial dimensions in subjects aged between 13 and 17 years. A retrospective longitudinal study including 50 patients (31 girls and 19 boys) whose end of orthodontic treatment coincided with the end of the post-pubertal period (13-14 years) involved a comparison of the cephalometric analyses for each patient between T1 (end of orthodontic treatment) and T2 (end of retention)...
