Short-term and long-term alterations of condylar position after bilateral sagittal split ramus osteotomy for mandibular setback: A preliminary before-after clinical trial.

Background: Because of the importance of the condyle, it is crucial to document all changes in its position after orthognathic surgery. Since previous studies in this regard are mostly controversial and limited by two-dimensional radiography technique, this study was conducted.

Materials And Methods: This prospective clinical trial was performed on 102 measurements (17 patients, 2 condyles each, and 3 time points).

Correlations among chronological age, cervical vertebral maturation index, and Demirjian developmental stage of the maxillary and mandibular canines and second molars.

Purpose: Estimation of growth spurt from chronological age or dental development is of clinical interest to orthodontists. Since results in this regard are highly controversial and limited, this study was conducted to investigate associations among chronological age, skeletal development (cervical vertebral maturity [CVM]), and dental calcification (Demirjian) in girls and boys, independently.

Methods: Panoramic radiographs and lateral cephalographs of 112 boys and 112 girls were evaluated.

Relationship between bridging and dimensions of sella turcica with classification of craniofacial skeleton.

Purpose: In orthodontics, it is essential to determine the craniofacial skeleton pattern (class I, II, III) for planning treatment. Sella turcica bridging that is seen on lateral cephalometric radiographs is considered as a normal finding. This study aimed to compare sella turcica bridging and its dimensions in patients with various craniofacial patterns.

Dosimetry of Three Cone Beam Computerized Tomography Scanners at Different Fields of View in Terms of Various Head and Neck Organs.

Background: Marketing new radiography devices necessitates documenting their absorbed X-ray doses. Since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed.

Objectives: The new devices were compared to the Promax three dimensional (3D) scanner at two fields of view (FOV) in nine critical head and neck tissues and organs.

The Effect of Emboss Enhancement on Reliability of Landmark Identification in Digital Lateral Cephalometric Images.

Background: Evaluation of the craniofacial bones is the oldest method to measure the facial proportion ratio in orthodontics.

Objectives: The purpose of this study was to evaluate the effect of emboss enhancement on the reliability of landmark identification in digital lateral cephalometric images.

Materials And Methods: Ten digital lateral cephalograms were selected from the archive of an oral and maxillofacial radiology center.

Relationship between carotid artery calcification detected in dental panoramic images and hypertension and myocardial infarction.

Background: Carotid artery calcification may be related to cerebrovascular accident, which may result in death or physical and mental disabilities in survivors.

Objectives: Our purpose is to study the association of carotid artery calcification (CAC) on dental panoramic radiographs and two risk factors of cerebrovascular accident (CVA) including hypertension and myocardial infarction (MI).

Patients And Methods: Panoramic images of 200 patients that were all women above 50 years of age (a population suffering from vascular diseases) were investigated.

Validity and reliability of the Persian version of the oral health impact profile (OHIP)-14.

Background: The need for assessment of oral health related quality of life has been increased over the last decades. The aim of this study was to develop a Persian version of the Oral Health Impact Profile (OHIP)-14 and to evaluate its reliability and validity for its use in Persian-speaking communities.

Methods: The original version of the OHIP-14 was translated into the Persian language using the back-translation technique.
