background and aims. one of the most common reasons for the inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. the aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. materials and methods. one hundred and twenty...

Background - In physical and forensic anthropology the skull is extremely informative with regard to identification of sex age an individual. It plays a vital role in establishing identity deceased. The has been described as “The bone core fleshy head face” Gender determination crucial human remains it narrows possibility for by 50 %. Many studies have observed gender differences based on heigh...

Abstract Aim The aim of the study was to evaluate cephalometric effects elastodontic appliance (EA) in management patients presenting with a skeletal Class II/1 malocclusion. Methods Twenty II treated using EA (Group EA) were compared 20 untreated children C). Cephalograms at start (T0) and after 24 months (T1) which time, skeletal, dental, aesthetic variables evaluated. A statistical evaluatio...

OBJECTIVE To define, in a group of children with nasal obstruction, the anatomical differences that differentiate those with quiet, unobstructed nocturnal respiration from those with obstructive sleep-related breathing abnormalities (snoring and obstructive sleep apnea). DESIGN Case series. PATIENTS Fifty-nine children aged 3 to 13 years (35 boys and 24 girls) with nasal obstruction and wit...

Lateral cephalometric radiographs of 35 Japanese male patients suffering from Duchenne muscular dystrophy (DMD) were taken longitudinally from 10 to 20 years of age. Eighteen landmarks were placed and 15 angles and four linear distances calculated. Profile diagrams (profilograms) were produced to analyse changes in craniofacial morphological growth in the DMD subjects. The measurements were the...

The shape of the mandible is used by orthodontists as an aid to orthodontic treatment planning, with different shapes displaying different growth characteristics and being associated with different functional patterns. However, the quantification of shape using conventional linear and angular variables does not always include details of some of the more subtle aspects of form. Fourier analysis ...

The purpose of this study was to systematically review the orthodontic literature to assess the effectiveness of a prediction of outcome of orthodontic treatment in subjects with a Class III malocclusion. A structured search of electronic databases, as well as hand searching, retrieved 232 publications concerning the topic. Following application of inclusion and exclusion criteria, 14 studies r...

El propósito de este trabajo fue profundizar en un procedimiento para la mejora investigación el área ortodoncia, y caso, analizar similitud medida los ángulos radiografía panorámica lateral cráneo. ángulo gonial puede ser medido panorámica, donde derecho e izquierdo se miden individualmente, disminuyendo riesgo error, pues no existe superposición imágenes como una La muestra está conformada po...

Spermatids derived from a single gonial cell remain interconnected within a cyst and elongate by synchronized growth inside the testis in Drosophila. Cylindrical spectrin-rich elongation cones form at their distal ends during the growth. The mechanism underlying this process is poorly understood. We found that developing sperm tails were abnormally coiled at the growing ends inside the cysts in...
