Third molar maturity index for discriminating between adults and minors: validation in an Iranian sample.

The life-altering effects of criminal trials necessitate providing reliable methods to distinguish adults (≥18) from minors (< 18). The present study aims to evaluate the accuracy of the third molar maturity index (I3M) introduced by Cameriere et al. (2008) in distinguishing adults from minors in the Iranian population.

Canine sexual dimorphism in crown and root dimensions: a cone-beam computed tomographic study.

The primary step in forensic odontological analysis is sex determination. The present study is one of the few studies that evaluated the accuracy of the combination of canine tooth root length and crown measurements for sex determination. The study sample comprised 196 cone-be am computed tomographic scans of individuals aged 20-80 years distributed in five age categories: 20-29, 30-39, 40-49, 50-59, and 60+ years old.

Symphysis morphology and mandibular alveolar bone thickness in patients with β-thalassemia major and different growth patterns.

Objective: The present study aimed to assess the morphology of symphysis and alveolar bone thickness (ABT) surrounding mandibular incisors in thalassemic patients, as compared to unaffected individuals.

Methods: This case-control study was conducted on lateral cephalograms of 60 thalassemic and 60 unaffected patients with Class II malocclusion seeking orthodontic treatment at Dental School, Shiraz University of Medical Sciences. The sample was divided into three subgroups including hyperdivergent, normodivergent, and hypodivergent, according to the Jarabak index.

Skeletal maturation and the location of the mandibular foramen within the ramus mandibulae.

Purpose: It is well documented that the mandible does not grow at a constant rate. There are significant correlations between the increase of mandibular size and cervical vertebral maturation. The peak growth velocity of the mandible occurs after the third stage of cervical vertebral maturation.

The impact of age mimicry bias on the accuracy of methods for age estimation based on Kvaal's pulp/tooth ratios: a bootstrap study.

Introduction: Methods based on pulp/tooth ratios proposed by Kvaal et al. (1995) have been widely used for age estimation in adults. The tendency of age estimates to mimic the age structure of the reference population, i.

Assessment of the relationship between the maxillary sinus and the canine root tip using cone beam computed tomography.

Background: The purpose of the present study is to investigate the relationship between the maxillary sinus and the canine root apices in cone beam computed tomographic images (CBCT) and to assess the amount of extension of the maxillary sinus to the anterior region of the jaw in different sexes and age groups.

Methods: CBCT of 300 individuals (154 males and 146 females) over 20 years (with a mean age of 35.12 ± 8.

Cone Beam Computed Tomography Analysis of Sphenoid Sinus Pneumatization and Relationship with Neurovascular Structures.

Background: The sphenoid sinus is considered as the most variable pneumatized structure of the skull.

Purpose: The aim of the present study was to determine the prevalence of the Onodi cell as well as to evaluate the relationship between the sphenoid sinus type of pneumatization and the presence of surrounding neurovascular protrusion using cone beam computed tomography (CBCT).

Methods: The CBCT images of 500 patients/996 sides [203 males (40.

Assessing the efficacy of a modified crushing technique for the management of concha bullosa: a cone beam computer tomography study.

Introduction: Although many surgical techniques exist to manage obstructive concha bullosa, there continues to be a drive to find the least invasive technique with the fewest complications and best results.

Objectives: The purpose of this study is to describe and assess the short- and long-term efficacy of a modified crushing technique for concha bullosa management.

Methods: Patients who met inclusion criteria underwent a detailed nasal examination and cone beam computed tomography imaging prior to and after septoplasty with crushing surgery for obstructive concha bullosa.

Association between Adult Attention-Deficit/Hyperactivity Disorder and Driving Behaviors among Iranian Motorcyclists.

Objective: To investigate the association between attention-deficit/hyperactivity disorder (ADHD) score and driving behaviors among motorcycle drivers in Iran.

Methods: This multi-center cross-sectional study was conducted on 1747 motorcyclists in three cities of Iran. We used a random sampling method in this study and gathered data using two standard questionnaires.

Assessment of mandibular characteristics in patients affected with β-thalassaemia major: A retrospective case-control study.

Objective: Thalassemia is the most common hereditary blood disorder across the world. This study aimed to identify some mandibular features of thalassaemic patients and compare them with unaffected counterparts.

Material And Methods: This retrospective case-control study was carried out on lateral cephalograms of 60 subjects (26 males, 34 females) with class II malocclusion and age range of 11 to 15 years.

A Cone-Beam Computed Tomographic Study of Alveolar Bone Morphology in Patients With Unilateral Cleft Lip and Palate.

Objective: To evaluate the bony support around the teeth adjacent to the unilateral cleft lip and palate (ULCLP) using cone-beam computed tomography.

Methods And Materials: Cone-beam computed tomographies of 48 cleft-adjacent teeth (28 anterior and 20 posterior to the cleft) and 48 noncleft control teeth were evaluated. The alveolar bone thickness at 3 and 6 mm apical to the cement-enamel junction (CEJ), the distance between the alveolar crest and CEJ (Alv-CEJ), and the presence of fenestration were assessed in buccal, palatal, and proximal surfaces.

Assessing the Accuracy of Caries Diagnosis in Bitewing Radiographs Using Different Reproduction Media.

Statement Of The Problem: After introducing digital radiography, practitioners started reading radiographs from computer monitors; however, many still prefer hard-copy radiographs.

Purpose: This study aimed to assess the possible superiority of either type of radiograph recording media (computer monitor, film, or paper) in diagnosis and perception of the depth of the cariogenic lesions.

Materials And Method: Twenty digital bitewing radiographs, obtained from 200 posterior extracted teeth, were displayed on an LG monitor and printed on paper and film using Kodak printers.

How the Prevalence of Pulp Stone in a Population Predicts the Risk for Kidney Stone.

Introduction: Conflicting researches exist on relationship between pulp stones and systemic disorders. Nephrolithiasis is a common disease with severe pain and discomfort with increasing prevalence worldwide. The purpose of this study is to evaluate the correlation between pulp and kidney stones to help find a method for early detection of kidney stones.
