AIM To investigate the prevalence of the talon cusps in a sample of Indian dental patients and their distribution among different types of teeth. To determine the presence of other dental anomalies associated with the talon cusps. METHOD 2740 out patients (1523 males and 1217 females) attending Oral Medicine department from November 2010 to January 2011 were screened for the presence of talon...

To investigate the prevalence, characteristics (ie, malocclusion, location, type), and sex distribution of hypodontia in an Iranian orthodontic population. A retrospective study was conducted using periapical and panoramic radiographs and study models of 1,751 subjects attending university orthodontic clinics (870 females, 881 males, age 9-27 years). The Chi-square test was used to analyze diff...

The use of the Finite Element Method (FE) is an appropriate way to study occlusal forces and tooth movement. The purpose of this study was to evaluate the effects of different occlusal contact patterns on tooth displacement in an adult dentition using a three-dimensional FE model of a human maxilla and mandible. Initially, images of a computerized tomography scan were redrawn in a computer prog...

T alon cusp refers to a cusp-like structure project ing from the cingulum area of a maxillary or mandibular anterior tooth. Shafer et al. and Mellor and Ripa reported that talon cusp is uncommon and occurs in maxillary and mandibular permanent incisors. Most cases of the anomaly have been reported in the permanent dentition. Ninety percent of the talon cusps occur in anterior permanent teeth, a...

Rodent mandibular incisors have a unique anatomical structure that allows teeth to grow throughout the lifetime of the rodent. This report presents a novel transplantation technique for studying the apical bud differentiation of rodent mandibular incisors. Incisal apical end tissue with green fluorescent protein from transgenic mouse was transplanted to wild type mice, and the development of th...

DESCRIPTION A 20-year-old man with a previous gunshot to the left mandible presented with left facial swelling and trismus after being assaulted in the face with a closed fist. Mouth opening from maxillary to mandibular central incisors was limited to 3 cm. Dedicated maxillomandibular computed tomographic (CT) scan demonstrated an isolated left zygomatic arch fracture impinging the coronoid of ...

Hypodontia is the congenital absence of one or more teeth because of agenesis. The most commonly missing teeth are the third molars, the maxillary lateral incisors and the second premolars. Cases are presented of three patients with a missing mandibular incisor.

Many appliances are described in the literature in the second molars class where you want to obtain a mandibular advancement . The aims of this study is to compared, with a literature review using PubMed from 1998 to 2016, dental and skeletal effects of Twin Block, the Bionator and Frankel II. The final results found in our research is that the Twin block appliances determines a greater positiv...

Complete mouth rehabilitation allows the dentist to solve multiple problems by controlling the restoration of many teeth. Guidelines and objective criteria for each area to be treated are essential when planning an extensive case. Esthetics, phonetics, and anterior guidance are affected by the height and inclination of the mandibular incisors. Placement of the mandibular incisal plane is import...

Fusions of teeth and talon cusp are two rare developmental dental anomalies, affecting both primary and permanent dentitions. Both the anomalies are mostly reported as isolated finding and are rarely associated with other dental anomalies. Talon cusp is more common in maxillary anterior teeth in permanent dentition and fusion is commonly reported in mandibular teeth in primary dentition. The co...
