The neuropeptide Calcitonin Gene-Related Peptide (CGRP) is a well-characterized neurotransmitter. However, little is known about the role of CGRP in osteogenesis and vascular genesis during the developmental formation of bone. In the present study, we assessed the abundance of CGRP mRNA and the mRNA of osteogenesis and vascular genesis markers in the foetal mouse mandible and leg bone (tibia). ...

Introduction: The aim of the present study was to evaluate the morphometric differences of the skull in male and female Zell sheep. Methods: For this purpose, 30 heads (15 adult males and 15 adult female) of Zell sheep breed were collected from the local slaughter-house. The skulls were prepared using the boiling maceration according to the usual techniques, and the mandible was dissociated fr...

In this work the structural behaviour of a mandible considering a unilateral occlusion is numerically analysed by means of the Finite Element Method (FEM). The mandible, considered as completely edentolous, is modelled together with its articular disks, whose material behaviour is assumed as elastic or hyper-elastic. The mandible model is obtained by computer tomography scans. The anisotropic a...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

objective: better understanding of the furcation anatomy may serve to decrease the risk of root perforation. the purpose of this study was to measure the thickness of root walls in the danger zone in mandibular first molars. materials and methods: the roots of 53 extracted human mandibular first molars were sectioned in the horizontal plane 4 mm below the orifice of the mesial and distal root c...

objectives: this study sought to assess the relation of mandibular cortical index (mci) with age, gender and gonial angle size in an iranian adult population using digital panoramic radiography. methods: we evaluated 370 digital panoramic radiographs of patients and divided them into five 10-year age groups. each radiograph was assigned to low (≤120°) or high (≥125°) angle groups in terms of th...

mesenchymal chondrosarcoma (mc) is an uncommon tumor with an aggressive behaviour. we present two cases of mc. the first one is a unique case of mc of the maxilla metastasized from the clavicle. the second describes mc in the mandible with extensive involvement of the condyle. a 31-year-old male and a 22-year-old male presented to saveetha dental college, with a 2-month history of progressive m...

introduction plasma cell dyscrasias are characterized by a monoclonal neoplastic proliferation of plasma cells. solitary bone plasmacytoma (sbp) is a local form of the disease with the vertebrae and long bones being the most frequently encountered sites. its prevalence in the maxillofacial area is extremely rare. case presentation a 70-year-old caucasian male patient was referred for the extrac...

PURPOSE In this study we tried to analyze the stress distribution in a symphyseal fractured human mandible reduced by 2 different methods--reduction with 1 miniplate or with 2 miniplates--by using finite element (FE) analysis, and then compared the results with an intact mandible. MATERIALS AND METHODS Three-dimensional FE models of an intact mandible and symphyseal fractured mandibles reduce...
