Abstract This is a global study that evaluated the undergraduate endodontic curriculum in dental schools worldwide. An online questionnaire sent to faculty members involved teaching at 50 institutions across six continents. The was modified version of previously validated survey comprised 46 questions three sections on essential aspects didactic, preclinical (PT), clinical trainings (CT), and assessments programs. response rate 76%. 63.2% have separate course, with 65.8% having dedicated...
Background: Calcium hydroxide has been used in dentistry since several decades. It a number of applications the field endodontics such as root resorption, intracanal medicament, and canal sealers. Although this material exhibits advantages, it also some limitations. Objectives: To review role calcium endodontics, focusing on its mechanism action, antimicrobial effects, different applications, cytotoxicity or biocompatibility, removal from canals. Materials Methods: An electronic search was...
We aimed to evaluate the impact of Virtual Reality Dental Simulators (VRDS) on preclinical training in endodontics for undergraduate dental students. Purposive sampling technique was used target students at two schools: Qatar and Turkey. After endodontic access cavity preparation upper anterior teeth using acrylic mannequins virtual reality haptic simulator, a questionnaire based combination open- closed-ended items distributed participants. The sample included 60 participants reported...
Dentists could fail to notice periapical lesions (PLs) while examining panoramic radiographs. Accordingly, this study aimed develop an artificial intelligence (AI) designed address problem. Materials and methods: a total of 18618 root areas (PRA) on 713 radiographs were annotated classified as having or not PLs. An AI model consisting two convolutional neural networks (CNNs), detector classifier, was trained the images. The localized PRAs using bounding-box-based object detection model,...
Objectives To report the prevalence of pulp stones (PSs) in molars orthodontically treated patients, investigate impact orthodontic treatment (ORT) using clear aligners (CAs) and fixed appliances (FAs) on development PSs molars, association between incidence during ORT studied variables. Materials Methods Pretreatment orthopantomograms (OPGs) 600 patients were assessed. Of those, posttreatment OPGs 272 available. Molars subdivided into four subgroups based type appliance force application:...
Abstract Purpose The study explored dental students’ perception of their professional identity (PI) development at a newly established college with problem‐based learning (PBL) curriculum. Methods Qualitative methods based on focus groups were used for data collection. conceptual framework the was informed by subject‐centered sociocultural approach to PI development. Purposive sampling collect from five undergraduate students gain deeper understanding in PBL environment. Results Out total 38...
Efforts to improve the performance of rotary NiTi instruments by enhancing properties alloy, or their manufacturing processes rather than changes in instrument geometries have been reported. The aim this study was compare in-vitro shaping ability three different nickel-titanium produced methods. Thirty simulated root canals with a curvature 35˚ resin blocks were prepared systems: AK- AlphaKite (Gebr. Brasseler, Germany), GTX- GT® Series X (Dentsply, Germany) and TF- Twisted Files...
Improvements in the thermomechanical processing procedures of NiTi wires have led to development new instruments that compose mainly martensite crystals, making wire stable at clinical condition. This study aimed comparing shaping ability two rotary nickel-titanium systems manufactured from different wires. Twenty simulated root canals each with a curvature 35° resin blocks were divided into groups 10 each. Canals first group prepared superelastic F360 (Gebr. Brasseler, Germany) while second...
Dental professionals can play a pivotal role in educating the public about harmful effects of smoking and encouraging them to quit habit.This study assesses attitudes practices tobacco cessation counseling (TCC) among dental Saudi Arabia.This questionnaire-based cross-sectional targeted dentists interns working government private sectors Arabia. We conducted descriptive analysis by using SPSS Statistics, version 25.0.A total 895 respondents (314 581 dentists) participated this survey....
Oral health self-efficacy is a fundamental determinant of behavioral changes among elderly patients. Objective: To assess the oral Saudi population aged 65 years old and above in Riyadh, Arabia. Methodology: This was cross-sectional survey conducted on individuals Riyadh. An Arabic version Geriatric Self-Efficacy Scale for Health (GSEOH) administered to all participants. The dependent variables included function, hygiene habits, dental visits. For statistical analysis, two independent sample...
To compare blood flow (BF) changes of teeth subjected to orthodontic forces during curve Spee (COS) leveling using different archwires (AW).Thirty subjects with COS > 5 mm were randomly assigned (1:1:1) into three groups based on the AW used: group 1: 0.017 × 0.025-inch stainless-steel (SS)AW, 2: 0.019 SSAW, and 3: 0.021 β-titanium (TMA)AW. In 3 groups, a mm-depth reverse was placed in AWs. A laser Doppler flowmeter used measure BF at time intervals (T0-T4).In AWs group, all measured reduced...
Purpose: Diabetes mellitus (DM) is associated with numerous oral complications, including frequent infections, periodontal diseases, hyposalivation, and xerostomia. The present study aimed to investigate salivary flow rate, xerostomia, health status among a group of Saudi diabetic patients as compared healthy controls. Patients Methods: This comparative cross-sectional involved 50 (aged between 15 70 years) 53 age- gender-matched Data collection was carried out using structured questionnaire...
<ns3:p>This report describes a clinical case of asymptomatic compound odontoma in the anterior left side maxilla associated with an impacted canine and supernumerary tooth gubernacular canal 47- year-old female no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise three-dimensional localization each structure assessment their spatial relationship structures before surgery. The treatment protocol involved surgical enucleation open extraction both teeth....
In this study, we evaluate the surface roughness (SR) of three thermally treated nickel-titanium rotary instruments (i.e., TruNatomy [TN], ProTaper Gold [PTG], and EdgeTaper Platinum [ETP]) after impact testing with multiple autoclave sterilization cycles using scanning electron microscopy (SEM). Overall, 60 files were sourced 20 TN, ETP, PTG files), each group was divided into four equal subgroups five (n = 5). An unsterilized assigned as pre-autoclaving (Cycle 0), other groups underwent...
Aim . During endodontic treatment, dentists may face various unwanted procedural accidents, at any stage of the treatment that might compromise outcome and bring obstacles to as well. This study aimed address analyze several ethical concerns relating behavioural conduct towards instrument separation well perforation crown and/or root during canal in Riyadh, Saudi Arabia. Method Hundred eleven questionnaires were distributed among working Riyadh university clinics government private sectors....
