Two female patients, aged 14 years 5 months and 17 years 3 months with skeletal Class III open bite and temporomandibular dysfunction are presented. They had previously been classified as orthognathic surgical cases, involving first premolar removal. The primary treatment objective was to eliminate those skeletal and neuromuscular factors that were dominant in establishing their malocclusions. ...

Talon cusp occurs as a result of disturbances during the morpho-differentiation stage of tooth development. It is more common on the palatal surface of the permanent maxillary incisors. It can be unilateral/bilateral, but can also occur on the same tooth. Only 2 published reports exist documenting talons on both labial and lingual surfaces of the same tooth in permanent incisors. The purpose of...

To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary ...

Dentigerous cysts are developmental odontogenic cysts associated with the crown of an unerupted tooth most commonly located at permanent Mandibular 3rd Molars and the Maxillary Canines. They rarely involve deciduous teeth and supernumerary teeth [5%]. We report successful management of two rare cases of maxillary labial swelling due to a dentigerous cyst associated with an impacted mesiodens. T...

The fly pharyngeal sense organs lie at the transition between external and internal nutrient-sensing mechanisms. Here we investigate the function of pharyngeal sweet gustatory receptor neurons, demonstrating that they express a subset of the nine previously identified sweet receptors and respond to stimulation with a panel of sweet compounds. We show that pox-neuro (poxn) mutants lacking taste ...

OBJECTIVES The purpose of this study was to determine buccal bone and soft tissue thicknesses and their correlation in the maxillary anterior region using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this cross sectional study, 330 sound maxillary incisors in 60 patients with a mean age of 37.5 years were assessed by CBCT scans. For better visualization of soft tissue, patie...

OBJECTIVE To compare, through computed tomography, alveolar bone thickness changes at the maxillary incisors area during orthodontic treatment with and without tooth extraction. METHODS Twelve patients were evaluated. They were divided into 2 groups: G1--6 patients treated with extraction of right and left maxillary first premolars, with mean initial age of 15.83 years and mean treatment leng...

Anatomy: Camelids have dentition designed for grinding of forages similar to other herbivores. They have incomplete rostral arcades with three lower incisors but only one upper incisor per side. The premolars and molars are referred to as the cheek teeth and are well established. The rostral and caudal roots of the cheek teeth do not communicate in llamas and alpacas. Disease can be confined to...

A new species of the psammophilous and brushlegged North American genus Amercaenis Provonsha and McCafferty, Amercaenis cusabo Provonsha and McCafferty, new species, is described from larvae taken from the Black River (North Carolina), the Pee Dee River (North Carolina), and the Savannah River (Georgia and South Carolina). The new species differs from the only other known species of the genus, ...

INTRODUCTION Children with intellectual and physical disabilities including autism are susceptible to dental trauma as a sequela from falls due to poor muscular coordination. In addition, their altered muscle tonus often results in an open bite with labial flaring of the maxillary incisors and lip incompetence, predisposing these teeth to fractures. This case report describes an alternative app...
