[Testing of dental enamel hardness by an in vivo method].
The authors studied the microhardness of sound enamel in healthy persons, with in vivo measurements by the Vickersdiamond, used in earlier tests. The evaluation of the impressions was done by a modificated image-analysis method. The method by Fosse et al, for in vivo microhardness measurements can bring good results in practice according to the investigations. The image-analysis makes the evaluation essentially easier. The intraindividual use of this method in longitudinal examinations eliminates the sources of error occurring at horizontal comparisons.
