Chronic medication use does not increase caries risk in all patients
Summary
Subjects
The subjects were South Australians over 60 years of age (from Adelaide and Mt. Garbier), with a mean age 75 years (SD 7 years); 57.4% were male. The sampling strategy described in a previous study was not described in this article. Baseline and 2-year data were collected in 1991 and 1993 respectively. In 1996, 5-year data were collected.
Exposure
Chronic (5-year) medication use.
Main Outcome Measure
The change in the caries index (coronal and root).
Main Results
The mean net caries increment was 2.23 (SD 3.32) decayed/filled surfaces. The mean adjusted caries increment (AdjCI) was 2.65 (SD 3.14). The mean AdjCI was higher, but not significantly, among those taking β blockers or antiasthma drugs and lower among users of anxiolytics/hypnotics or nonsteroidal anti-inflammatory drugs. For root surface caries, the mean net caries increment was 1.90 (SD 3–23) and the mean AdjCI was 2.21 (SD 2.83)
