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...

The orthodontic treatment of an adult patient with a skeletal Class III malocclusion, increased anterior facial height, negative overjet, and bilateral posterior crossbite is presented. Treatment options included mandibular first premolar or third molar extractions with dentoalveolar compensation or combined surgical-orthodontic treatment. Mandibular third molar extraction with dentoalveolar co...

Results: Maxillary central and lateral incisors and canines typically presented with a single canal of type I canal configuration. In mandibular teeth, most of the central incisors showed type I (57.4%) canal configuration. Type III was found in 37.0% of the cases. The incidence of type III canal configuration in mandibular lateral incisors was 55.9%. The remainder was distributed mainly betwee...

OBJECTIVE This study evaluated alveolar bone loss around mandibular incisors, induced by the Herbst appliance. METHODS The sample consisted of 23 patients (11 men, 12 women; mean age of 15.76 ± 1.75 years), Class II, Division 1 malocclusion, treated with the Herbst appliance. CBCT scans were obtained before treatment (T0) and after Herbst treatment (T1). Vertical alveolar bone level and alveo...

The root canal anatomy of mandibular incisors can present a number of variations . This case report illustrates the abnormal configuration and successful non-surgical endodontic management of complex canal systems in mandibular lateral incisors.

A 16-year-old woman with congenitally missing permanent mandibular second premolars and central incisors presented for treatment. The prosthodontic treatment consisted of placing 2 internal tri-lobed narrow platform implants in the mandibular second premolar spaces, along with zirconium abutments and all-ceramic crowns. A 4-unit zirconium fixed partial denture was fabricated to restore the miss...

OBJECTIVES To quantify incisor decompensation in preparation for orthognathic surgery. STUDY DESIGN Pre-treatment and pre-surgery lateral cephalograms for 86 patients who had combined orthodontic and orthognathic treatment were digitised using OPAL 2.1 [http://www.opalimage.co.uk]. To assess intra-observer reproducibility, 25 images were re-digitised one month later. Random and systematic err...

Central incisor, congenital absence, hypodontia, tooth agenesis. Abstract Hypodontia is the congenital absence of less than six teeth because of agenesis. The absence of teeth may be unilateral or bilateral. There are reports showing unilateral occurrence of permanent mandibular incisors. But agenesis of bilateral mandibular central incisors is not well documented in the literature and comprehe...

Introduction: Congenital missing of maxillary lateral incisors and mandibular second premolars are one of the most common developmental dental anomalies that can affect patient’s function and aesthetics. The aim of this study was to determine the prevalence and pattern of congenital missing of lateral maxillary teeth and second mandibular premolars in patients referred to the Dental Faculty of ...

BACKGROUND The aim of the study was to determine the root canal morphology of permanent mandibular incisor teeth in the Indian subpopulation with the use of cone beam computed tomography (CBCT). MATERIAL/METHODS CBCT images of 200 patients with 800 permanent mandibular incisors, fulfilling necessary inclusion criteria and aged 18 to 60 years were evaluated. The number of roots, number of root...
