Evaluation of maxillary canine root and maxillary bone thickness and density in patients with displaced maxillary canines: A cone-beam tomography study.

Introduction: This study investigated lateral incisor and canine morphology and dimensions, maxillary bone density, and volume in subjects with displaced maxillary canines.

Methods: Cone-beam computed tomography images for 134 palatally displaced canines (PDCs), 57 buccally displaced canines (BDCs), and 87 nondisplaced canines (NDCs) were analyzed. Canine and lateral incisor dimensions, alveolar bone dimensions, and maxillary bone volume and density were measured.

Cone Beam Computed Tomography Analysis of Upper Airway Measurements in Patients With Obstructive Sleep Apnea.

Purpose: To explore the validity of cone beam computed tomography (CBCT) as one of many predictive tools that can be used (alone or in conjunction) to help in identifying high-risk cases of obstructive sleep apnea (OSA) that should get the earliest possible referral to a sleep specialist for standard diagnostic polysomnography, and to identify imaging airway parameters that may be predictive of OSA severity.

Methods: Using a case-control design, 45 subjects matched by age and sex (22 OSA cases and 23 controls) were included in this study. Subjects were assigned as cases depending on a sleep study with apnea-hypopnea index (AHI)>5 and as controls depending on a Berlin questionnaire score identifying low risk or no risk of OSA.

The alveolar bone height of the primary and first permanent molars in healthy 6- to 9-year-old Jordanian children.

Aim: To establish a threshold cemantoenamel junction (CEJ)-alveolar bone crest (ABC) distance in healthy 6- to 9-year-old Jordanian children and determine the effect of pathological changes, physiological changes, gender, and age on the CEJ-ABC distance.

Design: Bitewing radiographs were made for 539 6- to 9-year-old children. Plaque index (PI), gingival index (GI), calculus index (CI), DMFS score, and pocket depth were all assessed through clinical examination.

Crown-root ratio of permanent teeth in cleft lip and palate patients.

Objectives: To determine root lengths of fully developed permanent teeth of cleft lip and palate (CLP) patients and to define their crown-root (C/R) ratios.

Method: Crown height and root length of permanent teeth were measured from panoramic radiographs of 44 CLP patients and 37 controls. A total of 1397 teeth were measured, and C/R ratios were calculated.

Prevalence of dental anomalies in a population of cleft lip and palate patients.

Objective: The aim of our study was to investigate radiographically the prevalence of dental anomalies in a group of Jordanian cleft lip and/or palate subjects.

Design: This is a retrospective review of panoramic radiographs of 78 subjects with cleft lip and/or palate that were evaluated from their file records and investigated for possible dental anomalies.

Results: Dental anomalies were found frequently in cleft lip and/or palate subjects.

Mineralization of the stylohyoid ligament complex in a Jordanian sample: a clinicoradiographic study.

Purpose: To record the prevalence of anatomic variations and the associated symptoms of mineralized stylohyoid complex (MSHC) in a Jordanian sample, and to investigate the possible factors responsible for mineralization.

Patients And Methods: This study was conducted at the Dental Teaching Clinics of Jordan University of Science and Technology in patients referred for panoramic radiographs. The MSHC, on either side of panoramic radiographs, was mapped out on tracing paper, the length directly measured, and the true length calculated.

Dental development in subjects with thalassemia major.

Aim: The aim of this study was to evaluate the dental development of patients with ss-thalassemia major and to compare it with unaffected children.

Methods And Materials: Panoramic radiographs of 44 thalassemic patients taken before the age of 16 years were examined. The subjects consisted of 29 males and 15 females ranging in age from 4.
