Objectives: To evaluate the retentive strength of overdenture attachments in 2-implant mandibular overdenture (2IMO) with implants placed at different positions and angulations.

Materials And Methods: Edentulous mandibular models were 3D-printed using CBCT images and Materialise Mimics software and the denture models using the intraoral scanner. Two standard implants were placed parallel at different positions from midline (5, 10, 15, and 20 mm) with 0-0 degree angulations and with different distal angulations (0-5, 0-10, 0-15, 5-5, 10-10, and 15-15 degrees) at 10±mm from midline representing 10 study groups.

Statement Of Problem: The edentulous mandible is commonly treated with a 2-implant overdenture. A change in diameter of the implants may affect the biomechanical behavior of the overdenture, but information on these effects is lacking.

Purpose: The purpose of this 3D finite element analysis study was to evaluate the biomechanical behavior of 2-implant mandibular overdentures (2IMO) and their individual components by using implants of different diameters.

Background: Emotional intelligence (EI) is considered to present a significant predictor of work performance whereas Transactional analysis (TA) is the relational perspective in communication in managing emotions. We evaluated the effect of psycho-educational training in EI and TA (TEITA) on EI among health professions undergraduates, with post-training, and at 1-month follow-up.

Methods: A total of 34 participants participated in the study where 17 participants were in the TEITA group and another 17 were in the control group.

Objective: Entrustable professional activities (EPAs) are tasks that a person who is qualified or is in the process to be credentialed are allowed to engage. There are several levels of entrustment based on degrees of supervision assigned to each EPA. This paper aims to describe the process and outcome of creating EPAs; validate EPAs relevant to undergraduate dental training.

Objectives: This paper reports on the effect of 6-month dental home visits compared to no dental home visits on 24-month caries incidence in 5- to 6-year-olds.

Methods: 5- to 6-year-olds attending kindergartens were randomized to receive either 6-month dental home visits and education leaflets (Intervention group) or education leaflets alone (Control group) over 24 months. To detect a 15% difference in caries incidence with a significance level of 5% and power of 80%, 88 children were calculated to be needed in the Intervention group and 88 in the Control.

Statement Of Problem: The 2-implant mandibular overdenture is a popular treatment for the edentulous mandible, but information on optimum implant positions and/or angulations and their stress and strain patterns is lacking.

Purpose: The purpose of this finite element analysis study was to evaluate stress and strain distribution patterns in 2-implant mandibular overdentures with different positions and angulations of implants under unilateral and bilateral loading.

Material And Methods: A cone beam computed tomography (CBCT)-based, 3-dimensional (3D) model of the mandible and an intraoral scanning-based 3D model of the denture were developed in the Mimics software program.

Introduction: Clinical audit is a quality improvement process that seeks to improve patient care and outcomes through the systematic review of care against explicit criteria and the implementation of change. The objective of this audit was to evaluate the quality of orthodontic chart documentation by dental undergraduates against established guidelines.

Materials And Methods: An audit checklist with 13 criteria for good documentation was adapted from guidelines proposed by the American Association of Orthodontists and British Orthodontic Society.

Objectives: The research aimed to investigate if emotional intelligence (EI) scores of dental undergraduates influenced their patients' satisfaction with the treatment received.

Methods: A 33-item EI questionnaire was completed by 46 dental undergraduates in a cross-sectional study. Responses, measured on a five-point Likert scale, were summed to yield EI scores.

The objective of this study was to evaluate the factors influencing the willingness to pay for a single tooth implant in Malaysia and to assess if an additional evidence-based patient education video increases the willingness to pay. A total of 100 subjects seeking single tooth replacement at the Oral Health Centre, International Medical University (IMU), Kuala Lumpur, Malaysia, were asked to complete questionnaires about personal demographics and personality traits. Subsequently, they were randomly allocated into two groups.

Background: The aim of this cross-sectional study was to evaluate the effect of family functioning on oral health related quality of life (OHRQoL) and dental caries status among 4- to 6-year-old Chinese pre-school children in Malaysia.

Methodology: This study was approved by the institutional Joint Research and Ethics Committee, International Medical University, Malaysia (number 373/2016); consisted of 180 eligible pre-school children from a private school. Study tools included demographic, clinical oral health data form, the Early Childhood Oral Health Impact Scale (ECOHIS) and family functioning-12-item general functioning subscale.

To determine the antibacterial effect of propolis nanoparticles (PNs) as an endodontic irrigant against biofilm inside the endodontic root canal system. Two-hundred-ten extracted human teeth were sectioned to obtain 6 mm of the middle third of the root. The root canal was enlarged to an internal diameter of 0.

Objective: Tooth pain among adolescents is a common event that impacts substantially on quality of life. The purpose of this paper is to explore the role of race in the tooth pain experience and associated care-seeking.

Design: A cross-sectional questionnaire survey was conducted on 14-18 years from four different public schools in Kuala Lumpur.

Background: The successful outcome of endodontic treatment depends on controlling the intra-radicular microbial biofilm by effective instrumentation and disinfection using various irrigants and intracanal medicaments. Instrumentation alone cannot effectively debride the root canals specially due to the complex morphology of the root canal system. A number of antibiotics and surfactants are being widely used in the treatment of biofilms however, the current trend is towards identification of natural products in disinfection.

Although there is clinical applicability of the palatal rugae as an identification tool in forensic odontology, controversy exists whether the palatal rugae patterns are stable or variable. The greater the genetic component, the higher the probability that palatal rugae patterns are stable. The aim of this study was to compare the palatal rugae morphology between full siblings and the proportion of variability due to genetic component.

Background: Palatal rugae are asymmetric ridges of connective tissue located behind the incisive papilla over the anterior hard palate. They serve as stable superimposition landmarks to assess tooth movement in orthodontics and as identification aids in forensic odontology. However, the stability of palatal rugae remains controversial.

Background: In 2012, nearly 4000 children in Malaysia were referred to hospital pediatric dental services due to dental caries. Recent research has reported the effectiveness of dental home visits in preventing caries development in young children. Dental home visits (DHVs) are described as an ongoing relationship between the dentist and their patients, providing all aspects of a preventive oral health care program in the presence of the parents at home.
