Use of crack cocaine increases tooth loss

Purpose: To evaluate the occurrence of tooth loss among crack cocaine users. Methods: A cross-sectional study was conducted with 106 crack cocaine users and 106 controls matched for age, gender, and tobacco use. Data were collected on socio-demographic characteristics, drug use, use of dental services, dental caries, periodontal disease, and the outcome (tooth loss). Results: Crack cocaine users had a greater frequency of tooth loss (55.7% vs. 36.8%), severity of dental caries and periodontal disease and less use of dental services than the controls (P< 0.05). After adjustments, tooth loss was 46% more frequent among crack cocaine users (PR= 1.46; 95%, CI: 1.10-1.93) as well as significantly more frequent among non-whites, those older than 24 years of age and those with high dental caries severity. Occurrence of tooth loss was significantly higher among crack cocaine users. These findings can contribute to the planning and implementation of prevention strategies and oral health care for individuals with a chemical dependence.
