Single versus two dental implants retained mandibular over dentures: comparison of function, patient satisfaction, oral health-related quality of life and success of treatment.

Objective: To compare the effectiveness of prosthetic rehabilitation of edentulous patients using conventional complete dentures (CD), single median dental implant retained over dentures (SIMOD) with over dentures retained by two dental implants (TIMOD).

Methods: Thirty completely edentulous patients (fifteen each arm) presented to the Faculty of Dental Sciences, University of Peradeniya were randomly selected for the SIMOD or TIMOD groups. Patients were initially provided with CD.

: A quantitative approach to assess the correlation of mammographic breast density with selected affecting factors.

Introduction: Breast density plays a significant role in increasing an individual's risk of breast cancer and its mortality rate.

Objectives: We aimed to assess the correlations of mammographic breast density with age, body mass index, weight, height and parity for the first time in Sri Lankan women.

Methods: 52 participants who underwent diagnostic mammographic examinations at a tertiary care hospital in Sri Lanka were selected for the study.

Effect of acid modified tea-waste biochar on crop productivity of red onion (Allium cepa L.).

Biochar has widely been utilized as an agricultural soil amendment owing to its enhanced surface properties and cost-effectiveness. In the present work, the influence of tea waste biochar (TWBC) upon acid modification on Allium cepa L. (red onion) growth has been studied.

Ambient PM and PM Exposure and Respiratory Disease Hospitalization in Kandy, Sri Lanka.

Evidence of associations between exposure to ambient air pollution and health outcomes are sparse in the South Asian region due to limited air pollution exposure and quality health data. This study investigated the potential impacts of ambient particulate matter (PM) on respiratory disease hospitalization in Kandy, Sri Lanka for the year 2019. The Generalized Additive Model (GAM) was applied to estimate the short-term effect of ambient PM on respiratory disease hospitalization.

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.

The influence of three acid modifications on the physicochemical characteristics of tea-waste biochar pyrolyzed at different temperatures: a comparative study.

Tea-waste is an abundant feedstock for producing biochar (BC) which is considered to be a cost effective carbonaceous adsorbent useful for water remediation and soil amendment purposes. In the present study, tea-waste BC (TWBC) produced at three different temperatures were subjected to nitric, sulfuric and hydrochloric acid modifications (abbreviated as NM, SM and HM respectively). Characteristics of the raw and modified BC such as ultimate and proximate analyses, surface morphology, surface acidity and functionality, point of zero charge, cation exchange capacity (CEC) and thermal stability were compared to evaluate the influence of pyrolysis temperature and of modifications incorporated.

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.

Genotypes of hepatitis C virus (HCV) in liver disease patients in Sri Lanka.

A total of 460 samples (serum or plasma) were obtained from clinically diagnosed liver disease patients from January 2006 to December 2007 and subjected to reverse transcription--polymerase chain reaction (RT-PCR) based detection of HCV. Of these, 32 samples (6.9%) were positive for HCV RNA.
