The implementation of an implant dental curriculum in U.S. dental schools has been consistently increasing from 33 percent in 1974 to 97 percent in 2004. Among these, only 51 percent have clinical components implemented. A survey of students conducted in 2004 at New York University College of Dentistry (NYUCD) showed an inadequacy in clinical implant restoration experience by graduation. This p...

Background: The coronavirus disease 2019 (COVID-19) is transmitted through saliva and respiratory aerosols. Concerns among dental clinicians over cross-contamination are among the main challenges currently present in the dental profession. This study aimed to assess dental students’ distress level and attitude towards their professional future following the emergence of the COVID-19 pandemic. ...

The fundamental factors in the diagnosis in the orthodontic treatment are the spacing condition, tooth size, arch form and its dimensions. Plaster model analysis is a time-consuming procedure. Dividers, calipers, and Boley gauges have provided the standart of measurement against which newer methods have been evaluated [1]. Various scanning techniques, including laser scans, structured light, de...

High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...

Ensuring a small enough failure probability is important for the design and selection of restorative dental ceramics. For this purpose, the two-parameter Weibull distribution, which is based on the weakest link model with infinitely many links, is usually adopted to model the strength distribution of dental ceramics. This distribution has been thoroughly validated for perfectly brittle material...

We explore the determinants of dental ill-health as measured by the occurrence of caries. A recursive bivariate probit model that was derived from health production and demand theory is employed to model caries, while taking account of dental care use. The data are from a follow-up questionnaire used in a longitudinal study of the Northern Finland 1966 Birth Cohort, with respondents aged 31 (n ...

Diabetes and salivary gland dysfunction are major factors that induce dental caries in experimental animals, but there are no reports analyzing the association of dental caries and salivary glands in an animal model of diabetes mellitus (DM). To clarify the initial development of dental caries and preceding salivary gland disorder, we performed a histopathological analysis on teeth and salivary...

OBJECTIVE To explore a) the relationship between parents'/guardians' dental anxiety and oral health literacy and b) those between these variables and background and oral health-related characteristics. METHODS Survey data were collected from 187 parents/guardians (81% female; average age 37 years). Dental anxiety was measured with the Dental Anxiety Scale - Revised (DAS-R) and oral health lit...

The objective of this study was to demonstrate the feasibility of using micro-CT scan of dental impressions for fabricating dental restorations and to compare the dimensional accuracy of dental models generated from various methods. The key idea of the proposed protocol is that dental impression of patients can be accurately digitized by micro-CT scan and that one can make digital cast model fr...
