parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

background: one of the most frequent concerns encountered in dental implant treatments is inadequate pre‑operative planning. panoramic radiographs are readily accessible and cost efficient. the aim of this study is to assess the accuracy of vertical measurements in mandibular molar andpremolar region on panoramic radiography. materials and methods : panoramic radiographs were made of a partiall...

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...
