Investigating the relationship between the type of occlusion and mandibular radiomorphometric indices in patients with normal facial height.

Background: The ability to predict the extent and direction of horizontal growth of the patient's face at an early age allows clinicians to timely identify cases that require treatment during the growth period and to ensure that appropriate treatment can be administered.

Objectives: The aim of this study was to investigate the role of the antegonial angle, gonial angle, antegonial notch depth, and the type of the antegonial notch on predicting horizontal facial growth in individuals with normal facial height.

Material And Methods: In this descriptive analytic study, lateral and panoramic radiographs of 180 patients aged 17-30 years with normal facial height who were referred to the School of Dentistry of Qazvin University of Medical Sciences and private dental clinics were investigated.

Frontal Bone Morphology in Different Age and Gender Groups Using Computed Tomography.

Background:  The shape of the forehead is primarily determined by the frontal bone, which holds significance for health and aesthetics. This study evaluated the morphology of the frontal bone in different age groups and genders using computed tomography (CT).

Methods:  This cross-sectional study was conducted on CT scan results of 220 patients divided into three age groups: 20-29.

Evaluation of Sella Turcica Variations in Lateral Cephalometric Radiographs and its Association with Malocclusion.

Objectives: Understanding the shape and size of the sella turcica may help predict future orthodontic treatment needs related to skeletal malocclusion. This study aims to assess different morphological types of the sella turcica in lateral cephalometric radiographs and its correlation with malocclusion, as well as the relationship between gender and linear measurements of sella turcica.

Materials And Methods: The lateral cephalometric radiographs of 410 volunteers (111 men and 299 women) aged 8 to 30 years were evaluated.

Relationship between Skeletal Malocclusion and Radiomorphometric Indices of the Mandible in Long Face Patients.

This study aimed to assess the relationship between skeletal malocclusion and radiomorphometric indices of the mandible in long face patients. This cross-sectional study evaluated 174 lateral cephalograms and panoramic radiographs of long face patients between the ages of 17 and 30 presenting at the Orthodontics Department of Qazvin Dental School. The gonial angle, antegonial angle, type of antegonial notch, and depth of antegonial notch were measured bilaterally on panoramic radiographs.

Diagnostic accuracy of conventional orthodontic radiographic modalities and cone-beam computed tomography for localization of impacted maxillary canine teeth.

Background: Orthodontic treatment planning for an impacted canine tooth requires accurate information about its position. The aim of this study was to compare the diagnostic accuracy of two conventional orthodontic radiographic modalities with cone-beam computed tomography (CBCT) for localization of impacted maxillary canine teeth.

Materials And Methods: Panoramic radiographs, lateral cephalograms, and CBCT scans of 30 patients with unilaterally impacted maxillary canine teeth were retrieved from the archives.
