statement of problem: condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (tmj) dysfunction and esthetic problems. treatment planning is based on the results of isotope scanning, clinical findings and patient age. single photon emission tomography (spect) is considered to be a sensitive method in the calculation of condyl...

BACKGROUND The purpose of this study was to evaluate the efficacy of preoperative versus intraoperative mandibular contouring using rapid prototyping technology. METHODS Ten patients requiring mandibular reconstruction had a preoperative mandibular plate contoured to a fabricated 3D mandibular model based on preoperative imaging. A traditional intraoperative plate was also contoured. Two surg...

PURPOSE Although free fibula flaps are widely used for mandibular reconstruction, their 3-dimensional position is difficult to control during conventional surgery. We aimed to improve this process by using computer-aided design (CAD) and surgical navigation. PATIENTS AND METHODS We retrospectively reviewed 29 benign tumor patients who underwent primary unilateral mandibular reconstruction wit...

Removable dentures are commonly used in routine dental practice at older ages. Accidental swallowing of various numbers of teeth has been reported in the literature before. However, total swallowing of removable mandibular prostheses in this size is a very rare emergency. In this study, we reported a case of accidental ingestion of a partially removable mandibular prosthesis and its final passi...

statement of the problem this study was designed to investigate the complications after surgical removal of mandibular third molars. patients and methods six hundreds and ninety eight lower third molars among 450 patients surgically extracted by general dentists from april 2005 to april 2006 were selected for this study. data were recorded by completing questionnaires regarding post surgical co...

condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...

Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma. The current study aimed at investigating the complete spectrum of pleural neoplasms and differentiating between them with the aid of immunohistochemistry (IHC). Methods: Consecutive pleu...

synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...

Osteomas are benign slow growing osteogenic tumors mostly arising in the craniofacial region and characterized by deposition of differentiated mature either or both cancellous compact bone. Osteoma accounts for 2-3% all bone primary with an incidence 10-12% among skeletal neoplasms. Objective: The objective this work is to describe a clinical case osteoma temporomandibular joint diagnosed maxil...

to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...
