ameloblastomas are slow growing, locally invasive, benign odontogenic tumors of an epithelial origin, accounting for approximately 1% of all oral tumors. a 40-year-old man presented with a chief complaint of a swelling over the left side of his face of 4 years’ duration. on examination, gross facial asymmetry was detected, and a well-defined swelling was noted intraorally involving the left max...

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

a 16 year old female was referred to an oral and maxillofacial radiologist for evaluation of a radiolucent area at mesial radicular aspect of right maxillary central incisor which was detected accidentally during pre-orthodontic treatment check ups. clinical examination showed no particular signs or symptoms except for slightly tenderness to lateral percussion. second radiograph with altered ho...

introduction a mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. mucopyocele is an infected mucocele. case report we presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. computed tomography scan showed opacification of the left maxillary sinus expanding thr...

AIM The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. MATERIALS AND METHODS The study samples include Denta scan® images of fifty patients with normally erupted bilatera...

Cholesterol granuloma (CG) is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-o...

The Drosophila maxillary palpus that develops during metamorphosis is composed of two elements: the proximal maxillary socket and distal maxillary palp. The HOX protein, Proboscipedia (PB), was required for development of the proximal maxillary socket and distal maxillary palp. For growth and differentiation of the distal maxillary palp, PB was required in the cells of, or close to, the maxilla...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

PURPOSE The purpose of this retrospective study was to compare the performance of cone-beam computed tomography (CBCT) and panoramic radiography in detecting the presence and location of maxillary sinus septa. MATERIALS AND METHODS This study included radiographic examination of 104 maxillary sinuses of 52 individuals (26 females, 50% and 26 males, 50%) whose panoramic radiographs and CBCT im...
