To evaluate and compare the speech in unilateral and bilateral cleft lip and palate children treated with and without presurgicalorthopaedics based on their palatal dimensions.Perceptual and digital evaluation of speech in cleft lip and palate childrencompared with there palatal dimensions.Twenty subjects with a history of cleft lip and palate or velopharyngeal dysfunction and speech disorder.G...

The paired-related homeobox gene, prx-1, is expressed in the postmigratory cranial mesenchyme of all facial prominences and is required for the formation of proximal first arch derivatives. We introduced lacZ into the prx-1 locus to study the developmental fate of cells destined to express prx-1 in the prx-1 mutant background. lacZ was normally expressed in prx-1(neo); prx-1(lacZ )mutant cranio...

introduction: the persian squirrel (sciurus anomalus) is the only member of the sciuridae family found in the middle east. some people maintain them as pets, thus their referrals to veterinary hospitals has been increased recently. several morphological studies have been carried out mainly on the arch of aorta and its branches in common rodents, small mammals, and domestic animals but there are...

We report a case of a 32-week-gestation male who presented initially with symptoms suggestive of an interrupted aortic arch. The absence of a VSD prompted further investigations, including a CT angiogram, which revealed that he had an extensive thrombus in his aorta. He underwent a successful aortic thrombectomy with arch repair on cardiopulmonary bypass support. In view of the extensive thromb...

Original scientific paper In order to obtain the skewed pressure characteristics, the physical model tests, adopting two kinds of excavation sequences of the bench method and the expanding method, were conducted under the different confining pressures for observation thermal radiation characteristics of the skewed pressure induced by step-by-step excavation for a double-arch tunnel. Firstly, un...

BACKGROUND Endovascular repair by stent graft has been developed as a safe and less-invasive treatment for descending thoracic and abdominal aortic diseases. In case of involvement of the aortic arch, the challenge in endovascular repair is to maintain blood flow to the brain and upper extremities. Several studies have been done trying to repair this difficult part of the aorta with different s...

OBJECTIVE To compare dental plaster model (DPM) and cone-beam computed tomography (CBCT) in the measurement of the dental arches, and investigate whether CBCT image artifacts compromise the reliability of such measurements. MATERIALS AND METHODS Twenty patients were divided into two groups based on the presence or absence of metallic restorations in the posterior teeth. Both dental arches of ...

The purpose of this study was to compare the dentoalveolar changes produced when using two different intraoperative surgical procedures for maxillary distraction osteogenesis. Eight patients were assigned into two groups according to the surgical procedure: down-fracture (DF, n = 6) vs non-down-fracture (NDF, n = 2). Lateral cephalograms and 3-D models before and after maxillary distraction wer...

BACKGROUND Given the benefits of radiographic cephalometric studies in determining patterns of dental-skeletal-facial normality in orthodontics, the aim of this study was to investigate the association between mandibular dental arch shape and cross-sectional and vertical facial measurements. MATERIALS AND METHODS It was analyzed plaster casts and teleradiographs in frontal and lateral norm be...
