The success of endodontic treatment requires the knowledge of tooth morphology and its variations. Mandibular incisor's anatomy presents a challenge when an endodontic access is made, because of its small size and high prevalence of two canals. We are describing a Weine's Type IV root canal configuration that was detected in a mandibular central incisor, which was demonstrated by a radiographic...

OBJECTIVES To study the association between gingival biotypes and inclination and position of the maxillary and mandibular incisors. METHODS This cross-sectional study included 142 consecutive orthodontic patients (64 males and 78 females) who were seeking orthodontic treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia from February 2013 to January 2014. Gin...

BACKGROUND The purpose of this controlled study was to investigate indirect effects on mandibular arch dimensions, 1 year after rapid palatal expansion (RPE) therapy. METHODS Thirty-three patients in mixed dentition (mean age 8.8 years) showing unilateral posterior crossbite and maxillary deficiency were treated with a RPE (Haas type) cemented on the first permanent molars. Treatment protocol...

Objective: Investigate the effects of heat-activated NiTi and stainless steel wires to evaluate potential changes in the position of mandibular incisors in extraction cases as correlated with treatment length. Method: The sample consisted of 36 individuals of both genders, Brazilian Caucasians with mean initial age of 15 years and 5 months with Class I and Class II malocclusions, divided into t...

INTRODUCTION Panoramic imaging is a technique for producing a tomographic image of the facial structures, maxillary, mandibular dental arches and their supporting structures [1]. The primary advantage of panoramic imaging is the broad coverage of the facial bones and teeth and the most common demerit is that of the resolution. Image interpretation in an OPG demands a systematic approach and a t...

Vertical loads and root surface strains in extracted teeth during lateral condensation using finger and hand spreaders were measured and compared with loads and strains at fracture. Six groups each of 10 teeth were tested: maxillary central incisor, premolar and molar; and mandibular incisor, premolar and molar. Root strains were measured using strain gauges mounted on the apical and middle thi...

A tooth displaced down into alveolar bone is an intrusive luxation. This injury usually is accompanied by comminution of alveolar fracture. The dislocation is frequently axial and radiographic examination reveals absence of periodontal space. The primary site for luxation injuries is the maxillary anterior region in the primary and permanent dentition with frequency higher in the primary dentit...

ntroduction: the aim of this study was to compare the accuracy of cone-beam computed tomography (cbct), digital radiography and tooth sectioning in evaluating root canal morphology of mandibular incisors in an in vitro setting. methods and materials: a total of 76 samples were imaged using cbct, and digital radiography in straight and angled views. the samples were then sectioned at different d...

Background: Hypodontia is one of the frequently observed dental anomalies in which dentofacial esthetics, phonetics, mastication, self-esteem and quality life can be adversely affected. Awareness disproportionate tooth number important must considered by orthodontists while making treatment plans to achieve proper occlusion, overbite, overjet, order restrain oral health deterioration. The aim t...
