OBJECTIVE To determine the location of center of resistance and the relationship between height of retraction force on power arm (power-arm length) and movement of anterior teeth (degree of rotation) during sliding mechanics retraction. MATERIALS AND METHODS Three human subjects with maxillary protrusion were selected for this study. Initial tooth displacements of maxillary right central inci...

The influence of the maxillary labial frenum in relation to midline diastema has been a proven fact clinicians for many years. A pilot study was carried out investigate relationship between low attachment and skeletal malocclusions (class I, II, III). Astonishingly, it observed that class III malocclusion had statistically high number cases with attachments. objective understand underlying dysp...

This study is focussed on the redescription of Ecdyonurus (Ecdyonurus) russevi Braasch & Soldán on the basis of the type material (holotype and paratypes) and topotypes collected in the Strandzha Mts. (Bulgaria). Female imago and subimago, larva and egg of the species are described for the first time and the male imago is redescribed in detail. The features distinguishing the species from other...

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...

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, ...

Propagation in higher animals requires the efficient and accurate display of innate mating behaviors. In Drosophila melanogaster, male courtship consists of a stereotypic sequence of behaviors involving multiple sensory modalities, such as vision, audition, and chemosensation. For example, taste bristles located in the male forelegs and the labial palps are thought to recognize nonvolatile pher...

The objective ofthis investigation was to test a small thermistor for oral use and to study temperature variation in non-inflamed oral mucosa Gingival and labial vestibular or sulcus temperatures were measured in 30 young dental undergraduate students with teeth with a gingival index score of 1 or less. Four sites of measurement. mesial, labial, distal and lingual, were made around the six sele...

Objectives: Assess the accuracy of 2D cephalograms reconstructed from 3D CBCT by comparing labial alveolar bone thickness over most forward maxillary incisor (MFMI) in 2 dimensions vs 3 dimensions. Materials and Methods: Sixty cone-beam computed tomography (CBCT) images were coded, 2-dimensional (2D) constructed using ray sum technique entire volumetric data On demand 3DAPP software (version1.0...

BACKGROUND Discrimination between edible and contaminated foods is crucial for the survival of animals. In Drosophila, a family of gustatory receptors (GRs) expressed in taste neurons is thought to mediate the recognition of sugars and bitter compounds, thereby controlling feeding behavior. RESULTS We have characterized in detail the expression of eight Gr genes in the labial palps, the fly's...
