摘要：Different Dental Caries Patterns among Smelter Workers with Dental Erosion: Shingo FUKAYO, et al. Department of Hygiene and Public Health, Teikyo University School of Medicine —Objective: The objective of this study was to describe the characteristics of dental caries among smelter workers with mild dental acid erosion. Subjects and Methods: A cross-sectional survey of 350 male workers at a copper-mine smelter in Japan revealed 28 cases of mild dental erosion. 26 subjects aged 40 yr and over were compared for their caries pattern with noncases in the corresponding age groups. Results: Although the number of overall DMFT (decayed, missing or filled teeth) was similar in the two groups (mean ± standard error, 14.7 ± 1.1 and 14.7 ± 0.4, respectively), site-specific DMFT had a different pattern: DMFT was significantly (p=0.012) less for maxillary anterior teeth among the cases (1.4 ± 0.3) compared with the non-cases (2.5 ± 0.1). The caries prevalence pattern of the non-cases was similar to that reported in the general population. Conclusion: The different caries pattern among the workers who had developed dental erosion indicates that low-level but consistent exposure to acid could have changed the risk for dental caries, possibly through the interactions of environmental acid and the pH-buffering action of saliva.
