Background: Methamphetamine (MAP) abuse is a significant worldwide problem. This prospective study was conducted to determine if MAP users had distinct patterns of tooth wear. Methods: Methamphetamine users were identified and interviewed about their duration and preferred route of MAP use. Study participants were interviewed in the emergency department of a large urban university hospital serving a geographic area with a high rate of illicit MAP production and consumption. Tooth wear was documented for each study participant and scored using a previously validated index and demographic information was obtained using a questionnaire. Results: Forty-three MAP patients were interviewed. Preferred route of administration was injection (37%) followed by snorting (33%). Patients who preferentially snorted MAP had significantly higher tooth wear in the anterior maxillary teeth than patients who injected, smoked, or ingested MAP (P = 0.005). Conclusion: Patients who use MAP have distinct patterns of wear based on route of administration. This difference may be explained anatomically.
