Students' Perception of Remote Extended Reality Simulation Systems Using Patient-specific Three-Dimensional-printed Models in Endodontic Education: A Pilot Study.

Objective: Extended reality (XR) technology using head-mounted devices enables the operator to visu-alise anatomical structures. We aimed to investigate student perceptions regarding applying XR simu-lation for transferring endodontic educational information between a lecturer in Japan and students in Saudi Arabia.

Methods: In this study, the students engaged with an XR simulation system and viewed teeth in virtual reality (VR).

Levels of Depression, Anxiety, and Stress Among Saudi Arabia's Medical and Dental Practitioners: A Cross-Sectional Study Following the Covid-19 Pandemic.

BACKGROUND Healthcare providers, particularly in dentistry and medicine, experience high stress levels, exacerbated by factors like patient anxiety, clinical work, and continuous training. The COVID-19 pandemic has further increased these risks. This study aimed to assess depression, anxiety, and stress (DAS) among dental and medical practitioners in Saudi Arabia, investigating influential factors on their psychological behavior.

Assessment of the prevalence and configuration of middle distal canals in the mandibular molars in a Saudi subpopulation using Cone-Beam computed tomography.

Purpose: The prevalence of the middle distal (MD) canal in the mandibular molar is significantly low among countries including the USA, Spain, Turkey, and Jordan; however, analysis of its prevalence and configuration has not been performed in Saudi Arabia. Therefore, we aimed to assess the prevalence and configuration of the MD canal in Saudi Arabia.

Methods: A retrospective analysis of 132 cone-beam computed tomography (CBCT) images was performed to evaluate the presence of the MD canal in patients visiting the Radiology Department of The College of Dentistry in King Saud University between July 2018 and July 2019.

Structural Features of the Mental Foramen in a Saudi Subpopulation: A Retrospective CBCT Study.

Introduction: Accurate and precise knowledge about the position, size, and shape of the mental foramen (MF) are critical in avoiding procedural complications. The MF's anatomical features vary among different ethnic groups, and various radiographic techniques have been used to determine these variations.

Aims: To evaluate the MF's shape, vertical and horizontal positions, and distance from the border of the mandible.

Adipogenic Stimulation and Pyrrolidine Dithiocarbamate Induced Osteogenic Inhibition of Dental Pulp Stem Cells Is Countered by Cordycepin.

Background: dental pulp-derived stem cells are easy to access and collect and are an excellent source of stem cells for regenerative therapy. These cells can interact with many biomolecules and scaffolds and can pass on the instructive signals to the sites of regeneration where they are used. In this regard cordycepin, a potential biomolecule derived from medicinal mushrooms with a spectrum of bioactive properties such as antioxidant, anti-inflammatory, and anticancer has not yet been tested for its effect on human dental pulp stem cells.

"Comparative evaluation of effect of toothbrush-dentifrice abrasion on surface roughness of resin composites with different filler loading:" An study.

Objectives: This study evaluated the effect of toothbrush-dentifrice abrasion on the surface roughness of two restorative posterior resin composites, Filtek Z250 and Z350 after simulated toothbrushing twice daily for a period of 3 months.

Methods: All the specimens were polished and cleaned and surface topography was evaluated by Veeco di CP-II Atomic Force Microscope (AFM) at six different points; similarly, these specimens were again subjected to evaluation after simulated toothbrushing using dentifrice. The surface roughness evaluation was done for AFM images using software made available and the factor measured were average roughness (Ra) and maximum peak to valley distance R(p v).

Ultrasound Imaging versus Radiographs in Differentiating Periapical Lesions: A Systematic Review.

Background: Ultrasonography is a non-invasive method of diagnosing periapical lesions while radiologic methods are more common. Periapical lesions due to endodontic infection are one of the most common causes of periapical radiolucency that need to be distinguished to help determine the course of treatment. This review aimed to examine the accuracy of ultrasound and compare it to radiographs in distinguishing these lesions in vivo.

Dentistry Amidst the COVID-19 Pandemic: Knowledge, Attitude, and Practices Among the Saudi Arabian Dental Students.

The recent pandemic outbreak has created a huge impact on dentistry. Dental students and dental professionals are at a higher risk because dental practice comprises close communication and widespread exposure to blood, saliva, and other body fluids. It is imperative to evaluate the knowledge and perceptions regarding Coronavirus (COVID-19) among budding dentists.

Factors Influencing Pain and Anxiety Before Endodontic Treatment: A Cross-Sectional Study Amongst American Individuals.

Objective: The present study aimed to assess preoperative levels of patient anxiety and pain before root canal treatment, and to explore variables that may affect these levels.

Methods: Ninety-five patients presenting for an endodontic visit were recruited for the study. A questionnaire was administered.

Location and shape of the apical foramina in posterior teeth: an in-vitro analysis.

Purpose: To analyze the morphology of shapes and positions of the apical foramina in permanent maxillary and mandibular posterior teeth.

Methods: Examination of the apical foramina was performed with a stereomicroscope at a magnification of 10×. The anatomic parameters evaluated were the shapes of the peripheral contours of the apical foramina (rounded, oval, asymmetric, and semilunar).

Prevalence and Characteristics of Three-rooted Mandibular Molars in Saudi Population: A Retrospective Radiographic Analysis.

Aims: To study the prevalence of three-rooted mandibular permanent first molars (PFM) among Saudi population in Al Zulfi.

Materials And Methods: Subjects were selected from the patients' records, College of Dentistry, Majmaah University, Al Zulfi, Kingdom of Saudi Arabia. Healthy patients with the presence of both mandibular PFM, orthopantomogram (OPG) and/or intraoral periapical (IOPA) radiographs were included in the study.
