PURPOSE The aim of this retrospective study was to determine the association between dental implants in the posterior region and traumatic occlusion in the adjacent premolars, using data collected during from 2002 to 2015. METHODS Traumatic occlusion in the adjacent premolars was assessed by examining clinical parameters (bleeding on probing, probing pocket depth, fremitus, and tooth mobility...

OBJECTIVE To evaluate the presurgical orthodontic tooth movement of mandibular teeth after dental decompensation for skeletal Class III deformities on the basis of vertical skeletal patterns. METHODS This cohort was comprised of 62 patients who received presurgical orthodontic treatment. These patients were divided into 3 groups according to their vertical skeletal patterns. Changes in the po...

human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. the incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. mandibular second premolars with three root canals and separate foramina are very rare. in this case report, endodontic management of a three-rooted mandi...

Background: Prediction the width of unerupted permanent canines and premolars is far important in assessing the space available to them in an attempt to prevent the future malocclusion. The present study utilized the combined mesio-distal crowns widths of maxillary and mandibular central incisors and first molars to predict the combined mesio-distal crowns widths of maxillary and mandibular can...

The apparently morphologically normal finding of multiple supernumerary teeth in absence of an associated systemic condition or syndrome is an uncommon phenomenon. Surgical removal of supernumerary teeth is indicated if eruption of the adjacent teeth has been delayed; altered eruption, displacement of adjacent teeth is evident or pathologies such as cystic lesion and resorption of adjacent toot...

Introduction: Knowledge of the internal anatomy of the tooth, apical foramen (AF) and mental foramen (MF) is considered a basic prerequisite before root canal surgical and non-surgical treatments. The aim this study is evaluation the distance and situation of AF & MF to anatomic apex of mandibular  premolar. Materials & Methods: In this cross-sectional study, CBCT images of mandibular p...
