Caries prevalence in heroin addicts.

The aim of the study was to determine the prevalence of caries in patients who are heroin addicts and the effects of salivary flow and saliva pH on its prevalence. The study included 200 subjects (100 subjects diagnosed with heroin addiction as the test group and 100 subjects taking no addictive substances as the control group). In both groups, saliva status was established by determining flow rates and pH of stimulated and unstimulated saliva.
