Results of a new in vivo method of measuring occlusal wear in bruxists

The reduction of bruxism using contingent EMG audible biofeedback: a case study

This report describes the use of EMG biofeedback to reduce bruxism in an 18-year-old woman. The behaviour was severe and not responsive to standard dental treatment. In addition to psychometric measures of affective status, objective measures of both the frequency and intensity of bruxing incidents were made, and a 4-week intervention conducted. On the bruxing and affective measures significant improvements were noted, as were reductions in associated pain and dysfunction.

Assessment of occlusal tooth wear in vervet monkeys by reflex microscopy

A biostereometric method was used to assess the tooth wear of monkeys fed either on one of two Western-type diets, which differed in their refined carbohydrate, fat and fibre contents, or on a combination of the two diets. Certain patterns of wear as a function of diet were observed but these could not be explained adequately in terms of diet roughness alone.
