Introduction: The purpose of this study was to evaluate the relationship between the position of mandibular third molar (M3) and vertical skeletal malocclusions. Methods: Materials for the study consisted of panoramic radiographs and lateral cephalograms of 73 fifteen to nineteen-year-old class I patients (girls=66%, boys= 34%). Patients were classified into three groups based on four vertical ...

OBJECTIVES The aims of this study were to evaluate the influence of gender and dental status on the mental index, mandibular cortical index and panoramic mandibular index from dental panoramic radiographs in elderly who had osteoporosis or did not have osteoporosis. METHODS Panoramic radiographs of 487 elderly dental patients (age range 60-88 years) were evaluated. It were recorded osteoporot...

statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...

The aim of this study was to analyse the correlation between external and internal mandibular morphology in adult or adolescent normal anthropological mandibles. Lateral radiographs of 31 symmetrical mandibles were analysed. The external morphology was defined by the gonial and beta-angles. In order to analyse internal morphology, a metallic pin was placed in the mental canal on the left side b...

BACKGROUND The relationship between impacted mandibular third molar and mandibular canal is important for removal of this tooth. Panoramic radiography is one of the commonly used diagnostic tools for evaluating the relationship of these two structures. OBJECTIVES To evaluate the accuracy of panoramic radiographic findings in predicting direct contact between mandibular canal and impacted thir...

Impacted mandibular third molars are located between the second mandibular molar and mandibular ramus. However, ectopic mandibular third molars with heterotopic positions are reported in the subcondylar or pterygomandibular space. The usual cause of malposition is a cyst or tumor, and malposition without a pathology is rare. This case report described an impacted mandibular third molar in the p...

BACKGROUND An in-depth understanding of the nuances of facial anatomy is the best means of preventing complications during facelift surgery. An appreciation of the operative details is complicated not only by the complexity of the anatomy but also by the variability in the nomenclature used. OBJECTIVES The authors have attempted to clarify these issues by detailing the relationships of the li...

introduction: it is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. the current study reviewed the root canal configuration of root canals in mandibular first and second premolars among iranian population based on independent epidemiological ...

introduction: in open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. this study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    materi...
