Pilot study on dental erosion in a Norwegian electrolytic zinc factory

Abstract

In 12 workers in a Norwegian factory using electrolytic methods to extract zinc, a relationship was found to exist between degree of erosion, number of teeth affected and the length of service. The prevalence of caries, abrasion and attrition was not higher than in comparable population groups. The correlation between diagnosis of erosion based on clinical examination, and diagnosis based on evaluation of color slides was good.
