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.
