background: different factors such as impression techniques and materials can affect the passive fi t between the superstructure and implant. the aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant defi nitive casts. materials and methods: four internal hex implants (biohorizons ø4 mm) were placed on a metal maxil...

Introduction: A study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. Many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. The aim of this study is to evaluate reliability and validity of dental measurement made on dig...

This cross-sectional study empirically tested a theoretical model of pathways and inter-relationships among community, family, and individual determinants of childhood dental caries in a sample of 630, 6-year-old children from the Netherlands. Children's decayed, missing, and filled teeth (dmft) scores were extracted from dental records. A validated parental questionnaire was used to collect da...

OBJECTIVES Aerosols generated during dental procedures have been reported to contain endotoxin as a result of bacterial contamination of dental unit water lines. This study investigated the determinants of airborne endotoxin exposure in dental healthcare settings. METHODS The study population included dental personnel (n = 454) from five academic dental institutions in South Africa. Personal ...

This paper is based on a study of the acquisition of dental fricatives by advanced Pakistani learners of English. The results are analyzed in light of predictions of the speech learning model (SLM: Flege 1995) using Optimality Theory (Prince & Smolensky 2004). In Pakistani English, dental fricatives [θ ð] are substituted with dental stops [t̪ d̪]. The current study aims to find out if Pakistani l...

Introduction: The World Health Organization recognizes oral health as an integral part of public health and believes that untreated oral diseases may greatly affect the quality of life, especially in pregnant mothers who should maintain their health and their babies’ health. Objective: This study aimed to determine the effect of educational intervention based on a health belief model on ora...

Background and Aim: Hearing impairment is a leading challenge in the education of deaf children. Compared to normal children, hearing-impaired (HI) children have poor oral health due to a lack of communication skills and effective health educations. This leads us to search for a proper method to educate these children. The present study aimed to assess the effect of different educational method...

BACKGROUND In primary care dentistry, strategies to reconfigure the traditional boundaries of various dental professional groups by task sharing and role substitution have been encouraged in order to meet changing oral health needs. AIM The aim of this research was to investigate the potential for skill mix use in primary dental care in England based on the undergraduate training experience i...

A virtual reality (VR) haptic dental training system could be a promising tool for future dental education. One major challenge is to develop a virtual tooth model which similarly reflected a real tooth having multiple layers with different mechanical hardness in each layer. The multi-layered virtual tooth model was successfully constructed in our virtual system. The constructed model allows us...
