Assessment of the quality of root canal fillings performed on extracted teeth by undergraduate dental students in a sample from Saudi Arabia.

Background: The educational process in the field of endodontics commences with preclinical exercises to enhance students' proficiency in cleaning, shaping, and performing root canal fillings. Therefore, this study aimed to radiographically evaluate the technical quality of root canal fillings performed by preclinical students on extracted teeth at the College of Dentistry, University of Ha'il, Saudi Arabia.

Methods: A total of 788 extracted human teeth received root canal treatment by undergraduate students.

Quality of Fixed Dental Prostheses and Patient Satisfaction in a Sample From Saudi Arabia.

Background: The objective of the study was to retrospectively assess the clinical performance of dental prostheses, single crowns, and three-unit bridges to identify clinical biological and mechanical complications in the Ha'il province of Saudi Arabia.

Methods: The study was conducted between March 2021 to October 2021 and included 421 patients who underwent crown and tooth-supported fixed partial denture (FPD) procedures at the Dental Polyclinics Center in the Ha'il region of Saudi Arabia from 2010-2020. The planned sampling approach was applied.

"All-on-4" and "All-on-6" treatment concept applied using computer-guided surgery in a patient: Case report with a 2-year follow-up.

This case aimed to assess the clinical and radiographic outcomes of the All-on-4 and the All-on-6 concept using three-dimensional computer-assisted treatment planning, and computer-guided surgery. Two years after the treatment, the "All-on-4" and "All-on-6" concepts provided effective treatment for immediate restoration and showed predictable outcomes in a completely edentulous patient.

The effect of selected commercially available mouth-rinses vs. curcumin photosensitizers in an artificial mouth model mimicking their use before meals on early colonizers single species biofilm.

Objective: The aim of the study was to determine the bacterial-adherence to the experimental pellicle pretreated with commercially available oral-rinse/ photosensitizer (mimicking use of oral-rinse/ photosensitizer before meals).

Materials And Methods: An artificial mouth (NAM) system was used for the development of single-species biofilm (Actinomyces viscosus, Streptococcus mitis and Streptococcus sanguinis respectively). Two commercially available oral-rinses containing active ingredients [Essential oils (EO) and Chlorhexidine gluconate (CHX) were used.

Efficacy of chlorhexidine, photosensitizers, green tea extract, and propolis on bond integrity and microleakage of caries-affected dentin: An in-vitro study.

Aim: The current study aimed to evaluate the efficacy of chlorhexidine (CHX), phycocyanin photosensitizer (PC), green tea extract (GTE), and propolis (PP) on the adhesive bond integrity and microleakage of caries-affected dentin (CAD) using etch and rinse adhesive system.

Material And Methods: A sum of 80 extracted human mandibular molars was collected and assessed using ICDAS criteria. Randomly CAD samples were treated with different disinfectants (n = 20) each CHX, PC, GTE, and PP.

Influence of Conventional Polymer, Hybrid Polymer and Zinc Phosphate Luting Agents on the Bond Strength of Customized Zirconia Post in Premolars-An In-Vitro Evaluation.

The aim was to identify the influence of conventional polymeric resin based cement (RC), hybrid polymer modified glass ionomer (RMGIC) and Zinc phosphate cement (ZPC) on the pull out strength of the customized zirconia post in premolars. Access cavity and root canals were performed in sixty premolar teeth with the standardized crown down technique (ProTaper Universal, Dentsply). Post space impressions were scanned, and the pre-sintered Zenostar Zr Translucent blanks (Weiland Dental, Pforzheim) were milled with the Opera-system to form the post.

Use of Photosensitizer, Glutaraldehyde, alcohol and Ultrasonics in disinfection of polished and rough surfaces of self-curing polymethyl methacrylate denture base material.

Aim: To assess the effectiveness of chemical, ultrasonic and photodynamic therapy (PDT) mediated disinfection against in-vitro biofilms colonized with C. albicans, S. oralis, and S.

Influence of Dental Glass Fibers and Orthopedic Mesh on the Failure Loads of Polymethyl Methacrylate Denture Base Resin.

The aim of the present study was to evaluate the fracture loads of polymethyl methacrylate (PMMA) complete denture bases reinforced with glass-fiber mesh and orthopedic casting tape (OCT) in comparison to conventional PMMA dentures under artificial aging. Dental fiberglass framework (Group 1) and OCT (Group 2 and 3) reinforced PMMA acrylic dentures were fabricated on the edentulous ridge. Ten PMMA dentures without reinforcement (Group 4) were included as controls.

Knowledge, Attitude, Practices and Viewpoints of Undergraduate University Students towards Self-Medication: An Institution-Based Study in Riyadh.

Rational and responsible self-medication (SM) is not only the key to better health outcomes, but also key to limiting adverse drug events. This institution-based cross-sectional study utilized seven- and four-item scales to assess the knowledge and attitude towards SM. Similarly, SM practices were measured using eight scale questions consisting of SM practice during the last six months, type of drug consumed, reason and frequency of SM, and so on.

Comparison of cotinine levels in the peri-implant sulcular fluid among cigarette and waterpipe smokers, electronic-cigarette users, and nonsmokers.

Background: Assessment of cotinine levels in the peri-implant sulcular fluid (PISF) may serve as a valuable biomarker of peri-implant diseases in nicotine-product users.

Purpose: The aim of the present study was to compare cotinine levels in the PISF among cigarette smokers, waterpipe users, electronic-cigarette users, and nonsmokers.

Materials And Methods: Cigarette smokers, waterpipe smokers, electronic-cigarette users, and nonsmokers were included.

Maternal-fetal Rhesus (Rh) factor incompatibility in Arar, northern Saudi Arabia.

Background And Aim: Rh isoimmunization still contributes to the neonatal morbidity and mortality due to non-immunization, under-immunization, and in rare cases, false Rh typing. The main objective of this study was to determine the prevalence of Rh incompatibility, mothers' knowledge about Rh incompatibility, mothers' knowledge about anti-D immunoglobulin and to show the pregnancy outcome of Rh negative mothers.

Methods: A cross-sectional study was carried out at the Maternity and Children Hospital in Arar city from November 2016 to May 2017.
