Objectives: Osteoporosis induces the reduction of bone mass and screening for low bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) has been the current gold standard test to determine osteoporosis. Panoramic radiography is widely used in dentistry for routine examination of jaws. The objective of this study was to determine the relationship between the mandibular angle (MA) values and the vertebral bone mineral density (v-BMD) in 20 osteoporotic men.
Study Design: In panoramic radiograms of osteoporotic men, the means were calculated for the mandibular angle values measured in the right and left mandible. v-BMD values were also calculated by manual analysis of DXA scans. The correlation between these variables was assessed.
Results: A negatively significant correlation was found between the MA and v-BMD.
Conclusions: The size of the mandibular angle decreases when osteoporosis increases. It is suggested that the mandibular angle may be useful in clinical dental practice to identify osteoporotic men with previously undetected low bone mineral density.

Objective: To investigate the effect of different microplate spacing on the relative displacement of the fractured mandibular ramus during mastication after using double microplates for fixation, using finite element analysis. This study aims to provide a theoretical basis for clinical design of the distance between two microplates.
Methods: Finite element models of the mandible, teeth, periodontal membrane, and microplates (Johnson & Johnson, thickness 1 mm) were established.

Haemangiomas are benign vascular tumours frequently encountered in head and neck region. The different systems of nomenclature leading to terminological confusion and management protocols for vascular lesions have been contentious issues and have undergone substantial paradigm shift over the years. A policy has been the mainstay of treatment owing to spontaneous regression of majority of paediatric hemangiomas along with sclerotherapy, laser therapy, drug therapy and radiotherapy.

Background: The most important part of orthodontic treatment (OT) is the pre-orthodontic examination (PE). Only a precise evaluation of clinical and radiological features can reduce the risk of complications.
Objectives: To develop practical guidelines for advanced clinical-radiological pre-orthodontic examinations and for qualifying patients for alveolar bone reconstructions.

Introduction: This study aimed to analyze midfacial skeletal shape asymmetry in skeletal Class III patients using a three-dimensional spatially-dense method.
Methods: Sixty skeletal Class III patients' cone-beam computed tomography images were retrospectively enrolled and divided into three groups according to occlusal plane inclination (OPI) and mandibular lateral deviation (MD). A spatially-dense template of the anterior outer surface of the midfacial skeleton was established and validated.

Objective: The primary rationale of the study is to assess the biomechanical aspects of Champy's, monoplanar, biplanar, and 3D strut plating systems using an model in the management of the angle of mandible fracture.
Methods: Thirty-two hemi-sectioned mandibles ( = 32) were obtained from adult goats and divided into four groups ( = 8) for different plating techniques: monoplanar, biplanar, Champy's, and three-dimensional curved angle strut plating. A customized biomechanical test machine simulated masticatory loads by applying compressive forces.
