Association between Tooth Loss and Opium Addiction: Results of a Community-Based Study on 5900 Adult Individuals in South East of Iran in 2015

BACKGROUND Like any other drug abuse, opium use is known to have detrimental effects on oral health. Oral hygiene neglect in opium users can lead to tooth loss resulting in further functional, esthetic, and dieting problems. Therefore, the aim of this study was to assess the association between tooth loss and opium addiction in a large-scale population. MATERIALS AND METHODS This study was part of an extensive study related to the risk factors of cardiovascular disease and conducted by the center for physiological research during 2012-2015 in Kerman. A total of 5900, 15-75-year-old individuals, were recruited by a single-stage random cluster sampling method. Factors including opium and smoking consumption, factors related to oral health, hygiene, and the number of missing teeth were examined. Data were collected through questionnaires, interviews, and physical examination. RESULTS Of 5900 individuals, 2662 (45.1%) were men and the rest were women, which 1011 individuals (17.1%) consumed opium. The prevalence of opium abuse was significantly higher in men. Regarding the oral dental indicators, the numbers of missing teeth (P < 0.001), decayed (P = 0.01), and the total index of decayed, missing, and filled teeth (P < 0.001) were significantly higher in addicts as compared to nonaddicts. The gingival index and community periodontal index scores were significantly lower in addicts. Addicted women had a higher prevalence of tooth loss. CONCLUSIONS Opium addiction is associated with higher tooth loss, especially, in women opium users. Dental practitioners and health politicians should pay special attention to the oral health of addicts before tooth loss occurs.
