[The condition of oral mucosa and periodontium in drug addicts].

The condition of the parodontium and oral hygiene were assessed in two 29-case groups of drug addicts before withdrawal treatment (hospital) and after it (in MONAR centre). The control group comprised 29 non-addicts. The PI index of Russel and OHI-S index were calculated. It was found that the mean value of PI and OHI-S was significantly greater before withdrawal treatment than after it, and in relation to controls. The values of both indices increased significantly with the duration of addiction. The authors concluded that drug-addiction through psychic deterioration leads to abandoning of oral hygiene which is the main cause of paradontal changes.
