Objectives: Methamphetamine (MA) is a widely used illicit drug and a nationwide public health concern. Although dental complications are consistently reported among MA users, yet limited nationally representative studies on the associations between MA use and oral health currently exist. Methods: Using the National Health and Nutrition Examination Survey 2009-2014, we analyzed 8,762 respondents aged 30-64 years who had completed a periodontal examination. MA use was self-reported; periodontitis, untreated caries, and missing teeth were assessed by calibrated dentists. Descriptive statistics as well as multivariable regression analyses were performed. Data were weighted to yield representative estimates of the US adult population. Results: Overall 7.8 percent of US adults aged ≥30 years had ever used MA. Ever-use prevalence was higher among males, whites, and individuals below the federal poverty level. Established MA users had a higher prevalence of untreated dental caries (36.6 percent), any periodontitis (54.8 percent), and severe periodontitis (12.2 percent) than those who had never used MA. The prevalence of any periodontitis was higher among current MA users (PR: 1.31; 95% CI: 1.05-1.62) than those who never used MA. Prevalence of untreated dental caries was higher among current MA users (PR: 1.53; 95% CI: 1.10-2.13) and established users (PR: 1.21; 95% CI: 1.02-1.48) than never users. Taking MA orally and/or through injection was associated with higher odds of severe periodontitis than orally only (AOR: 3.72; CI: 1.79-7.75). Conclusions: MA users had a higher prevalence of periodontitis and dental caries. Continued research assessing the relationship between MA use and oral health can inform clinical interventions and management of dental diseases in MA users.

BackgroundCocaine is the second most abused illicit drug in the United States. To date, no study has examined the association between cocaine use and oral health with a nationally representative sample. Our study examined the association between cocaine use—singly and with other substances—and oral health outcomes, including periodontitis and untreated caries, among US adults.MethodsData for 11,753 individuals, aged ≥30 years, who completed a periodontal examination, in the 2009 to 2014 National Health and Nutrition Examination Survey (NHANES) were analyzed. Descriptive analyses and multivariable binary logistic regression analyses were conducted on weighted data.ResultsOverall, 17% (20.5 million) of US adults aged ≥30 years had ever used cocaine, with higher likelihood seen among males, non‐Hispanic whites, and those living in poverty. Current cocaine use prevalence was 2.6% (3.2 million). By number of co‐used substances, the odds of having any periodontitis were higher among cocaine users who consumed ≥3 other substances (adjusted OR = 2.47; 95% CI = 1.15 to 5.30) when compared with solely cocaine users. By type of substance co‐used, odds of having untreated caries were greater among those reporting cigarettes (adjusted OR = 1.94; 95% CI = 1.21 to 3.11) or methamphetamine (adjusted OR = 5.40; 95% CI = 1.92 to 15.14) usage. Odds of any periodontitis were higher among those reported ancillary cigarette use (adjusted OR = 2.84; 95% CI = 1.60 to 5.04) compared with cocaine‐only users.ConclusionsIn addition to a positive association between periodontal disease, dental caries, and cocaine use, select co‐usage elevated the risk of oral disease. Patients should be screened for and counseled regarding substance abuse to facilitate a successful quit.
