Background

Researchers have reported rampant caries among methamphetamine users. The authors investigated the prevalence of dental disease and associated risk behaviors in methamphetamine users compared with those in heroin users.

Methods

This pilot project was a cross-sectional study of an ongoing cohort of young adult injection-drug users (IDUs) in San Francisco. Participants completed an oral health questionnaire administered by a research assistant, and dentists performed clinical examinations to record the participants' data in terms of scores on the decayed-missing-filled surfaces (DMFS) index, presence of residual roots, scores on an oral hygiene index and whether any salivary hypofunction was observed.

Results

The prevalence of dental disease among 58 young adult IDUs was strikingly high compared with that in the U.S. general population; however, the authors found no difference in the level of dental disease between users of methamphetamine and users of heroin. The mean DMFS score and number of decayed surfaces exceeded 28 in both groups.

Conclusions

Although the authors detected no difference in dental disease between methamphetamine and heroin users, they found a high prevalence of caries and caries-associated behaviors in the sample of young adult IDUs.

Clinical implications

Given the high level of dental disease observed in this population of young adult IDUs, one next step may be to explore the feasibility and effectiveness of providing low-intensity preventive measures (such as distribution of chlorhexidine rinses or xylitol gum or application of fluoride varnishes) through outreach workers.
