Background: Social media has evolved beyond its conventional purpose of communication and information sharing to become a potent tool for disseminating health and oral health awareness. This study seeks to assess the patterns and related factors of using social media platforms to access health and oral health information among Sri Lankan adults, with special emphasis to promotion of oral health awareness.

Methods: In March 2023, individuals aged ≥ 18 years residing in Sri Lanka, who are users of social media participated in this electronic questionnaire-based survey.

Effect of addition of titanium dioxide nanoparticles on the antimicrobial properties, surface roughness and surface hardness of polymethyl methacrylate: A Systematic Review.

Polymethyl Methacrylate (PMMA) denture-base resins have poor surface properties that facilitates microbial adhesion causing denture stomatitis. This systematic review aims to evaluate the effect of different sizes and percentages of titanium dioxide nanoparticles (TiO2NP) on the antimicrobial property, surface roughness and surface hardness of PMMA denture base resin.  A systematic search of English peer-reviewed articles, clinical trial registries, grey literature databases and other online sources was performed using the PRISMA-S Guidelines for and studies.

Perceptions of Dental Undergraduates Towards Online Education During COVID-19: Assessment from India, Nepal and Sri Lanka.

Linear and Volumetric Analysis of Maxillary Sinus Pneumatization in a Sri Lankan Population Using Cone Beam Computer Tomography.

Objective: The objectives of this study were to evaluate the linear and volumetric measurements of the maxillary sinus in relation to sex and side on cone beam computer tomographic (CBCT) images in a Sri Lankan population.

Methods: A total of 20 sets of CBCT images selected from the database at the Division of Oral Medicine and Radiology, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka, were evaluated. Linear measurements were obtained in a craniocaudal (height), anteroposterior (length), and mediolateral (width) dimensions.

Does the Level of Confidence Exhibited by Dental Students Predict the Outcome of Complete Denture Therapy?

Materials And Methods: Fifty-seven final-year dental students in the year 2019 and the first edentulous patient managed by them were recruited for the study. A fourteen-item questionnaire was given to the students to assess their level of confidence just before commencement of the treatment. Questionnaire for the patients was used to assess their satisfaction both with the operator and the dentures.

A cone beam computed tomographic analysis of the greater palatine foramen in a cohort of Sri Lankans.

Objectives: To determine the size and position of the Greater Palatine Foramen using CBCT.

Materials And Method: GPF was evaluated on 50 CBCT's which were obtained at the Division of Oral Medicine and Radiology, FDS, University of Peradeniya, The distance of each GPF to the mid maxillary suture (MMS), Anterior Nasal Spine (ANS), relationship of the GPF to the molar teeth and diameter were measured in different orthogonal planes using measurement tools integrated to the CBCT software.

Results: Mean diameter of the GPF in females and males were 3.

Evaluation of the styloid process in a Sri Lankan population using digital panoramic radiographs.

Objective: The objectives of this study were to evaluate the normal radiographic length of the styloid process (SP), prevalence and type of elongation, and angulation of the styloid process in relation to sex and side on digital panoramic radiographs in a Sri Lankan population.

Methods: A total of 100 digital panoramic images selected from the database at the Division of Oral Medicine and Radiology, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka were evaluated for the radiological features of the styloid process. Lengths greater than 30 mm were consider as elongated.

Effectiveness of Procedural Video Versus Live Demonstrations in Teaching Laboratory Techniques to Dental Students.

Even though the traditional live demonstration method is commonly used in teaching laboratory techniques to dental students, it has many drawbacks. The aim of this study was to assess the acquisition of knowledge, practical skills, and perceptions of dental students who had a live demonstration versus procedural video on arranging artificial teeth. All 79 third-year dental students at a dental school in Sri Lanka, who had no previous experience in arrangement of teeth, were randomly divided into two groups in 2016.

Sociodemographic profile and oral health status of thalassemic patients attending the National Thalassaemia Centre, Kurunegala, Sri Lanka.

Aim: The aim of the present study was to investigate the sociodemographic profile and oral health status (Decayed, Missing, Filled Teeth [DMFT] and periodontal health) of thalassemic patients compared to healthy individuals.

Methods: The data were collected by means of an interviewer-administered, pretested, and validated questionnaire, followed by oral examination. Patients attending the outpatient department, who were age and sex matched, but without any diagnosed or suspected long-term illnesses, were considered for the control group.

Awareness, attitudes, need and demand on replacement of missing teeth among a group of partially dentate patients attending a University Dental Hospital.

Objective: Our objective was to assess awareness, attitudes, need and demand on replacement of missing teeth according to edentulous space, age, gender, ethnicity, educational level and socio-economical status of the patient.

Results: 76.2% of the study group was opined that the missing teeth should be replaced by prosthetic means.
