[Analytic measurement of the solubility of the enamel surface exposed to acid and morphometric study of the resulting erosion in rat incisors treated with aluminum].

Their method of examination is based on the area analytical examination of scanning electromicroscopic photographs made of the enamel surfaces corroded with acid. By means of their method the area distribution of the enamel surfaces has been determined on which no detectable changes were formed after the acid action. The results obtained that way have also been compared with the results of analytical measurements. Their examinations were performed on uppar incisors of rats treated with aluminium.
