The purpose of this retrospective case-control study was to compare the cephalometric features of parents of children with cleft anomalies to those of parents of normal children in the hope of finding potential markers of predisposition for this condition. There were 22 sets of parents of cleft children (study group) and 22 sets of parents of normal(More)
INTRODUCTION Even with advances in materials and techniques, demineralization around brackets during orthodontic treatment continues to be a problem. The purpose of this in-vivo study was to evaluate the effect of a fluoride varnish on enamel demineralization adjacent to bonded brackets. METHODS Fifteen patients who needed at least 2 premolars extracted(More)
OBJECTIVE The aim of this study was to investigate three-dimensional molar displacement after distalization via miniscrews and a horizontal modification of the trans-palatal-arch (TPA). METHODS The subjects in this clinical trial were 26 Class II patients. After the preparation of a complete set of diagnostic records, miniscrews were inserted between the(More)
AIM To evaluate and compare the short-term (post-retention) skeletal and dental changes following bone-borne and tooth-borne surgically assisted rapid maxillary expansion (SARME) using cone beam computed tomography (CBCT). SUBJECTS AND METHODS In this randomized clinical study, 30 patients with transverse maxillary deficiency underwent either tooth-borne(More)
OBJECTIVES After maxillary expansion, a long period of retention is necessary to prevent early relapse. Therefore, it is beneficial to accelerate bone formation in the expanding midpalatal suture to reduce relapse. This study was designed to evaluate the effect of dietary vitamin C on osteogenesis of rat midpalatal suture during expansion. MATERIALS AND(More)
Article Incorrect patient positioning and the resultant image distortion occur in many radiographic examinations. This study aimed to assess the effect of tilting, rotation and tipping of the head on the accuracy of maxillofacial transverse measurements made on cone beam computed tomography (CBCT) scans. The CBCT scans were obtained in central position of(More)
AIM This study aims at examining the difficulty in performing forced eruption of impacted maxillary canines, using CBCT information and according to experienced orthodontist's opinion. The second aim was to find the most important factors related to this decision. METHODS Based on a careful literature review on impacted maxillary canines, ten main factors(More)
INTRODUCTION The rough surface of Hawley removable appliances provides an environment for plaque accumulation, leading to enamel demineralization. The aim of this study was to evaluate the effect of silver nanoparticles incorporated into acrylic baseplates of orthodontic retainers on Streptococcus mutans colony-forming units. METHODS Sixty-six orthodontic(More)
Replacement of the impacted maxillary canines with implants is a great challenge for all dentists. Adequate implant space, sufficient space between the roots, alveolar bone bed, thin labialgingiva and the guiding role of canine in a mutually protected occlusion make the choice of implant position with proper diameter more difficult. In this article we(More)
PURPOSE To evaluate and compare the short-term skeletal and dental changes following surgically assisted rapid maxillary expansion (SARME) with or without pterygomaxillary disjunction (PTMD) using cone beam computed tomography (CBCT). MATERIAL AND METHODS In present study, a total of 15 consecutive patients with transverse maxillary deficiency underwent(More)
