[Dental and mouth mucosal findings in drug addicts]

100 drug addicts and 116 alcoholics, who were compared with 100 non-addicts of corresponding age, exhibited an extraordinarily intensive manifestation of dental caries, expecially at the cervical region. This observation appears to be partly a result of drug-induced changes in metabolism as well as the concomitant asialia and xerostomia and predominantly a result of poor oral hygiene and dental care. These latter ones fell proportionally with the disintegration of social status. Drug addicts show rather frequently fractures and fissures of partially distroyed teeth as a result of bruxism. 78% of the investigate drug addicts suffered from profound inflammatory parodontopathy, 42% showed pigmentation of the gingival and/or buccal mucosa. The dental surgion should pay attention to the possible danger of an hepatitis infection.
