BACKGROUND The objective of this study was to investigate the stress distribution in the bone around zygomatic and dental implants for 3 different implant-retained obturator prostheses designs in a Aramany class IV maxillary defect using 3-dimensional finite element analysis (FEA). MATERIAL AND METHODS A 3-dimensional finite element model of an Aramany class IV defect was created. Three diffe...

OBJECTIVE To determine the prevalence and severity of dental fluorosis, as well as factors associated with its occurrence, in seven cohorts of children before and after the implementation of a fluoridated salt program in 1991. MATERIAL AND METHODS A cross-sectional study was carried out in 1,373 children aged from 6 to 12 years in Campeche, Mexico. Data were collected by means of a questionna...

PURPOSE To assess California dental hygiene educators' perceptions of an application of the American Dental Hygienists' Association's (ADHA) advanced dental hygiene practitioner model (ADHP) in medical settings where the advanced dental hygiene practitioner collaborates in medical settings with other health professionals to meet clients' oral health needs. METHODS In 2014, 30 directors of Cal...

A combination of the increasing costs associated with providing a complex clinical program and an ever-reducing education-based income finds dental schools throughout Australia continuing to face serious financial risk. Even more important is the growing workforce crisis in academic staffing faced in almost all dental schools as the impact of the widening gap between private practice incomes an...

Dental personnel planning is important in formulating policy in dental education, dental public health programs, and dental care delivery systems. The purpose of this literature review is to illustrate the use of dentist-to-population ratios, need-based models, and demand-based models in the determination of appropriate supply of dental personnel. A historical perspective is provided that demon...

Three-dimensional computer models of dental arches play a significant role in prosthetic dentistry. The microfocus X-ray CT scanner has the advantage of capturing precise 3D shapes of deep fossa, and we propose a new method of measuring the three-dimensional morphology of a dental impression directly, which will eliminate the conversion process to dental casts. Measurement precision and accurac...

Concurrent with the decline in dental caries has been an increase in the prevalence of dental fluorosis, a side-effect of exposure to greater than optimal levels of fluoride during amelogenesis. The mechanisms that underlie the pathogenesis of dental fluorosis are not known. We hypothesize that genetic determinants influence an individual's susceptibility or resistance to develop dental fluoros...

Background: Health utilization inequality is a major concern for health policymakers. Equality in utilization of services is very important for having a healthy society. The aim of this study was to describe inequality in dental care utilization in Iran, Therefore, concentration index, its curve, and the predictors of inequality in utilization of dental services and their spending were calculat...
