AI Article Synopsis
- The study aimed to analyze the root canal anatomy of mandibular first premolar teeth specifically from an Emirati subpopulation using decalcification and clearing techniques.
- A total of 100 teeth were examined, revealing that the most common canal pattern was Vertucci Type I (65%), with oval canal orifices being the most frequent shape (36%).
- The findings indicated a significant prevalence of mesial invaginations (44%) and the presence of multiple canals in 35% of the teeth studied.
Article Abstract
Objective: The purpose of this study was to determine the root canal anatomy of mandibular first premolar teeth in an Emirati subpopulation using a decalcification and clearing method.
Materials And Methods: One hundred permanent mandibular first premolar teeth extracted for orthodontic purposes from an Emirati subpopulation from the United Arab Emirates were used for this study. They were subjected to decalcification and clearing. The tooth length, the canal orifice shape, mesial invagination, canal pattern, the location of apex, presence of lateral canals, and intercanal communications were determined.
Results: The most common canal pattern was the Vertucci Type I (65%) followed by Type V (14%) and Type IV (13%). The most common type of canal orifice seen was the oval shape (36%) followed by the round shape (25%). Mesial invaginations were seen in 44% of the teeth. The mean tooth length was 19.9 mm, and apical deltas were seen in 24% of teeth.
Conclusion: The Vertucci Type I canal pattern was the most prevalent in the mandibular first premolars while the occurrence of multiple canals was noted in 35% of this population.

Owing to the unique inheritance pattern of the X chromosome, X-chromosomal short tandem repeat (X-STR) analysis represents a valuable tool in forensic DNA examination-particularly in complex kinship cases, missing person investigations, and disaster victim identification. We analyzed buccal swabs from 429 unrelated Korean males for forensic statistical parameters of 12 X-STRs. Among the 427 individuals analyzed (2 were excluded), DXS10135 was the most informative marker (polymorphism information content [PIC] = 0.

Article Synopsis
- Sexual dysfunction (SD) is a widespread issue among people with Parkinson's disease (PD), but it is often underreported and untreated, especially in various ethnic groups due to cultural beliefs.
- A study conducted in the UAE involving 513 patients found that SD was more prevalent in non-Emirati individuals, and it significantly impacted their quality of life and anxiety levels.
- The research concluded that SD affects all ethnicities similarly and emphasized the importance of culturally sensitive counseling to improve awareness and treatment.
Comparative Assessment of Pharyngeal Airway Dimensions in Skeletal Class I, II, and III Emirati Subjects: A Cone Beam Computed Tomography Study.

Article Synopsis
- - The study aimed to analyze the pharyngeal airway dimensions of Emirati individuals based on different skeletal patterns, using CBCT scans from 103 adult subjects classified into Class I, II, and III skeletal groups.
- - Findings indicated significant associations between airway measurements and facial metrics, with correlations observed between volumes of the nasal cavity, nasopharynx, oropharynx, and hypopharynx, as well as between these volumes and anterior facial height.
- - Notably, skeletal Class I exhibited a larger nasopharynx volume compared to Class II and III, while other airway parameters showed no significant differences; the study concluded that various airway parameters correlated with anterior facial height across the different skeletal patterns.

Introduction And Aims: Violations of the mandibular canal (MC) and mental foramen (MF) and subsequent injuries to their neurovascular bundle have been reported after surgical and nonsurgical dental procedures. Besides using advanced technologies such as cone-beam computed tomography (CBCT), clinicians should be aware of the anatomy and location of MC and MF in different populations. This study aims to describe the morphologic characteristics of the MF, MC, and its intrabony location in relation to the apices of mandibular posterior teeth in an Emirati subpopulation using CBCT.

Background: After childbirth, mothers are particularly vulnerable to mental health problems including anxiety and depression, which often remain undetected and untreated. In the United Arab Emirates (UAE), recent figures revealed a substantial prevalence of postpartum depression. However, postpartum mental health remains largely understudied in the country's clinical and research settings.
