The present experimental work analyzes the development of different mandibular units and its likely impact on the direction of mandibular displacement during facial development, and the relation between the mesiodistal dimension of the first, second, and third molars and the length of the mandibular corpus in a model of protein undernutrition with muscular atrophy in growing rats. Sixteen Wista...

OBJECTIVE To evaluate the sensitivity, specificity, accuracy, and predictive values of magnetic resonance imaging (MRI) in the assessment of mandibular involvement in oral-oropharyngeal squamous cell carcinoma. DESIGN Prospective study. SETTING University hospital. PATIENTS Forty-three patients with oral or oropharyngeal squamous cell carcinoma undergoing marginal or segmental mandibulect...

The aim of this report is to present a successful combined surgical and pharmaceutical treatment in the highest stage medicine-related osteonecrosis jaw (MRONJ). A 70-year-old man treated for metastatic prostate cancer concomitant with hypertension diabetes presented due exposure jawbone. Initial imaging studies suggested MRONJ, biopsy did not confirm bone metastasis oral cavity. Marginal resec...

statement of problem: the goal of a successful endodontic surgery is to establish an adequate seal in apical region. therefore during surgery, root-end resection is essential for an appropriate situation and proper access.purpose: the aim of this study was to determine the most appropriate root-end resection angle to establish adequate apical seal in periapical surgerymaterials and methods: for...

This paper reports on an experimental animal study evaluating a method of mandibular reconstruction in dogs using autogenous corticocaneclous bone graft and fibrin glue. Eight animals underwent a resection at the mandibular body and primary reconstruction was carried out using osteosynthesis plates and screws. The defect was bridged with an autogenous particulate bone graft from the anterior il...

OBJECTIVE To determine the diagnostic accuracy of a dental computed tomographic software program, DentaScan, in assessing mandibular bone invasion in patients with squamous cell carcinoma (SCC) of the oral cavity clinically fixed to the mandible. DESIGN Retrospective chart review. SETTING Academic tertiary care medical center. PATIENTS Thirty-six consecutive patients underwent DentaScan i...

BACKGROUND This study aimed to analyze differences in necrotic changes between cortical and cancellous bone in resection margins after segmental mandibulectomy for advanced mandibular osteoradionecrosis. METHODS Anteroposterior bone specimens from eleven patients who underwent segmental mandibulectomy with simultaneous free fibula flap reconstruction for advanced osteoradionecrosis were analy...

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region. The computerized tomography in coronal plane revealed a hypodense lesion in the posterior reg...

BACKGROUND Mandibular osteoradionecrosis is the most devastating complication after radiation therapy for head and neck malignancies. Quality of life (QOL) after surgical treatment is unclear. METHODS A retrospective cohort analysis (1997-2007) was conducted of all patients treated at our institution for stage II and III mandibular osteoradionecrosis. Nineteen of 35 patients responded to a mo...

An animal study is presented, evaluating a method of mandibular reconstruction using a poly(D,Llactide) (PDLLA) scaffold. Six goats underwent a continuity resection of the mandibular angle. The defect was bridged with a preshaped PDLLA scaffold, filled with an autogenous particulate bone graft from the anterior iliac crest, and fixed with two preshaped titanium plates. To accelerate bone healin...
