Aim: Traumatic dental injuries occur frequently in children. Treatment and follow ups are important to avoid short long term complications. The aim of this study was investigate the prevalence sequelae permanent anterior teeth following trauma their predecessors period 2005 2011. Methods: This performed retrospectively according data from records 79 children (53 boys, 26 girls), who were treate...

OBJECTIVE To locate the centre of resistance of consolidated units of four and six anterior teeth during retraction. METHODS Twelve three-dimensional (3D) models were designed in SolidWorks of the anterior segment with four and six teeth and their supporting structure. A proper force system was applied in each model to retract the teeth bodily. The exact location of the centre of resistances ...

although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. this paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. this report describes questions concerning the etiology of ove...

Although all genera of Callitrichinae feed on tree exudates, marmosets (Callithrix and Cebuella) use specialized anterior teeth to gouge holes in trees and actively stimulate exudate flow. Behavioral studies demonstrate that marmosets use large jaw gapes but do not appear to generate large bite forces (relative to maximal ability) during gouging. Nonetheless, the anterior teeth of marmosets lik...

Panoramic radiographs from 1026 patients were examined for the presence of completely impacted teeth. The prevalence of completely impacted teeth in the edentulous jaw was lower than that in the dentate jaw in both the upper and lower jaws. The prevalence of completely impacted third molars in the edentulous jaw was also lower than that in the dentate jaw. However, there was no difference in th...

OBJECTIVE To compare the amount of anchorage loss of the maxillary posterior teeth and amount of retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth. MATERIALS AND METHODS The sample consisted of 30 female adult patients with Class I malocclusion and lip protrusion who needed maximum posterior anchorage. The sample was subdivide...

Developmental anomalies affecting the number of teeth are occasionally encountered clinically. The incidence of supernumerary teeth is approximately 1-3%. Among these are the maxillary anterior teeth, the maxillary molars, and the maxillo-mandubular premolars, in terms of descending order of occurrence. Supernumeraries occur rarely in the mandibular anterior teeth region. They may be either sup...
