Abstract
INTRODUCTION: Antacids and acid suppressants (i.e., proton pump inhibitors and histamine2-blockers) are commonly used by individuals with heartburn and gastroesophageal reflux disease (GERD). Frequent heartburn and breakthrough symptoms of GERD have been shown to contribute to dental complications. The aim of this study is to compare the likelihood of erosive tooth wear (ETW) among users of antacids or acid suppressants. METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES, 2003-2004) to identify a nationally representative sample of adults (age ≥ 18) who underwent an oral health exam by trained dental examiners. Self-reports of use of antacids and prescribed acid suppressants were collected by trained personnel during a home interview and used to classify individuals into groups. Erosive tooth wear was defined in NHANES using Smith and Knight's Tooth Wear Index modified by Millward, et al., which rates the severity of ETW from 0 (sound tooth surface) to 3 (complete loss of enamel). Erosive tooth wear was evaluated for 40 tooth surfaces; 24 proximal (facial or incisal) and 16 distal (lingual or occlusal) surfaces. Erosions were categorized based on location and severity. We used weighted linear and logistic regression to compare means and estimate the prevalence of erosions for each group. Estimates were adjusted for age, sex, and race/ethnicity. RESULTS: NHANES ETW data were available for 4,414 adults; antacid users (n = 595), acid suppressant users (n = 386), and non-users (n = 3,433). The mean number of assessable tooth surfaces varied between groups (P > 0.001). Erosive tooth wear was more prevalent among those who reported the use of antacids or acid suppressants compared with non-users, however the difference was not statistically significant (P = 0.06). The percent of patients with ETW on at least one distal tooth surface was higher for antacid and acid suppressant users (P = 0.01). In addition, acid suppressant users had a higher prevalence of extensive tooth wear (P = 0.007). CONCLUSION: Individuals using antacids or acid suppressants (potentially for control of acid-reflux symptoms) are associated with a higher rate of dental complications, as suggested by the prevalence of erosions on distal tooth surfaces. In addition, extensive erosions were more common among users of acid suppressants than non-users. Emphasizing the importance of following recommendations from the American Dental Association for routine dental care may be particularly important for these individuals.
