Geographic comparisons of the incidence of dental erosion: a two centre study.

This study revealed that the premolars in both arches are most commonly afflicted with erosion. The same results were obtained in an earlier study conducted by Sognnaes, Wolcott & Xhonga (1972) and Xhonga, Wolcott & Sognnaes (1972) evaluating the erosion pattern on extracted teeth. These findings should be helpful in further investigation into the aetiology and treatment. Educational, epidemiological and preventive concerns derive from a study establishing the dental erosion frequency on a large population sample (approximately 600 individuals and 1500 teeth). The comparative results for both locations used will provide a more significant basis for future studies of a similar nature.
