Effect of acidity upon attrition–corrosion of human dental enamel
Journal of the Mechanical Behavior of Biomedical Materials, 2015Attrition-corrosion is a synthesized human enamel wear process combined mechanical effects (attrition) with corrosion. With the rising consumption of acidic food and beverages, attrition-corrosion is becoming increasingly common. Yet, research is limited and the underlying mechanism remains unclear. In this study, in vitro wear loss of human enamel was

Principal axis analysis of dental attrition data
American Journal of Physical Anthropology, 1979AbstractThe principal axis method is an age independent analysis method for dental attrition data which avoids many problems associated with earlier methods of analysis, correlation and regression. A principal axis equation is determined from the scatter of M1 on X and M2 on Y, and the slope of the equation can be used to indicate rate of wear.

In summary, the attrition rate for the recent dental school freshman classes has been reduced to 3 1/2 %. The national freshman enrollment of US dental schools can be expected to have approximately a 7% attrition rate by the time of graduation. The reasons for student withdrawal are evenly divided between personal and academic problems.

Dental attrition and degenerative arthritis of the temporomandibular joint
Journal of Oral Rehabilitation, 1981SummaryThe extent and rate of occlusal attrition in relation to degenerative arthritis of the temporomandibular joint were studied in 101 skulls representing early Aboriginal man in Australia. Joint degenerations affected 40% of the specimens and were associated with both the rate and extent of tooth attrition. Age, unaccompanied by tooth wear, was not

Reconstruction considerations for severe dental attrition
The Journal of Prosthetic Dentistry, 1980Alternative approaches toward the resolution of difficulties associated with severe attrition are offered. A clinical approach is advocated which first proves the acceptance of an increase in the occlusal vertical dimension before initiating definitive treatment. The various aspects of removable treatment are considered.

Relationships between age and dental attrition in Australian aboriginals
American Journal of Physical Anthropology, 1991AbstractTooth wear scores (ratios of exposed dentin to total crown area) were calculated from dental casts of Australian Aboriginal subjects of known age from three populations. Linear regression equations relating attrition scores to age were derived. The slope of the regression line reflects the rate of tooth wear, and the intercept is related to the

Dental Morphology, Proportions, and Attrition
2005Abstract The abundant dental remains from Dolní Věstonice and Pavlov consist of teeth present in the alveoli of the six associated skeletons, in the Pavlov 2 and 3 maxilla and mandible, and in the collections of isolated elements from Dolní Věstonice I and II and Pavlov I (Chapter 5).

Bite force and dentofacial morphology in men with severe dental attrition
American Journal of Orthodontics and Dentofacial Orthopedics, 1994Patients with severely worn dentition were interviewed and clinically examined, and only those were included who had no or minimal subjective symptoms or clinical signs of craniomandibular disorder. During a 14‐month screening period, only 7 patients fulfilled the inclusion criteria; all were men.

ABRASIVE PARTICLES IN TOBACCO PRODUCTS: A POSSIBLE FACTOR IN DENTAL ATTRITION
The Journal of the American Dental Association, 1995Tobacco products are known to cause oral soft-tissue lesions, but they may also directly affect the teeth. Abrasive particles contained in tobacco products may contribute to dental attrition. We studied tobacco samples from 16 brands of cigars, eight brands of snuff, four brands of chewing tobacco and several unprocessed tobacco leaves used as cigar ...

Analysis of dental attrition and mortality in the Medieval village of Tirup, Denmark
American Journal of Physical Anthropology, 2004AbstractNew directions and new questions raised in the study of health in the past justify this reanalysis of the pattern of dental attrition in the Medieval Danish population of Tirup. Dental attrition was scored on all permanent molars from the Tirup skeletal sample.
