PURPOSE To describe the features of impacted upper canines and their relationship with adjacent structures through three-dimensional cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS Using the CBCT scans of 79 upper impacted canines, we evaluated the following parameters: gender, unilateral/bilateral occurrence, location, presence and degree of root resorption of adjacent tee...

Q1. In the lingual system, the force to the center of resistance of a tooth is different from that in the labial system. In the present case, the upper incisors tipped lingually after intrusion, as shown in the cepha­ lometric superimpositions. I think that the intrusive force against the upper posterior teeth was applied lingually to the center of resistance, and, therefore, the upper posterio...

The purpose of this study was to evaluate the position and aspects of maxillary canine impactions in the Korean population and investigate its comparison with the previous reports, while aiding in the establishment of diagnosis and treatment planning by revealing the influential factors of root resorption associated with such impactions. The subjects of this study consisted of 186 teeth from 14...

OBJECTIVES To investigate the effect of enamel matrix derivative (EMD) on periodontal healing of replanted teeth in animal models. MATERIALS AND METHODS The authors searched MEDLINE, PubMed, EMBASE, Cochrane Library, Web of Knowledge and Scopus for articles published up to Oct 2012. Animal studies in which EMD was applied in transplanted or replanted teeth with adequate controls and histologi...

Root resorption is a common squeal of traumatic injury to the dentition. Its progression can be minimized by early diagnosis and appropriate treatment. This case report presents the diagnosis and management of a case of trauma induced trio of apical root resorption, intraradicular root resorption and infrabony defect in maxillary central incisor. The main aim in treating such cases of resorptio...

background: low- level laser therapy has been used to stimulate the orthodontic tooth movements (otm) previously. furthermore, in the orthodontic treatments accompanying tooth extractions, the adjacent teeth move towards the extraction sites and close the space in some cases. then, the adjacent tooth movements must be prevented in the treatments requiring space. laser stimulates and at some dos...

INTRODUCTION There is still ambiguity about whether continuous or intermittent orthodontic forces produce more root resorption. This prospective randomized clinical trial was designed to compare root resorption with these 2 force application patterns. METHODS The sample consisted of 16 maxillary first premolars from 8 patients who required bilateral extractions as part of their orthodontic tr...
