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.
在两组各有29名吸毒者中，分别在戒毒治疗前（住院时）和戒毒治疗后（在MONAR中心）对牙周状况和口腔卫生进行了评估。对照组由29名非吸毒者组成。计算了Russel的PI指数和OHI - S指数。结果发现，PI和OHI - S的平均值在戒毒治疗前显著高于治疗后，且与对照组相比也更高。这两个指数的值都随着成瘾时间的延长而显著增加。作者得出结论，吸毒通过精神恶化导致忽视口腔卫生，而这是牙周变化的主要原因。
