Salivary profile of recovering drug users in Indonesia

To determine the salivary ph and buffering capacity in recovering drug abusers. it was a cross-sectional study with descriptive research design through a study conducted in 116 residents of rehabilitation center of the national narcotics bureau,lido,west java. salivary samples were analyzed using gc saliva-check buffer kit. the mean unstimulated salivary flow rate (ussfr) and stimulated salivary flow rate (ssfr) were 0.46±0.25ml/min and 1.3±0.70ml/min respectively (p<0001). 69.0% of residents had normal unstimulated salivary ph,95.6% of residents had normal stimulated salivary ph,and while 48.3% of residents had a relatively low salivary buffering capacity. this study showed that the residents had normal salivary ph values,but tend to had low buffering capacity. there are various factors that contribute to buffering capacity of saliva,including the protein,phosphate,and carbonate buffering system,salivary flow rate,the activity of carbonic anhydrase vi,and salivary gland condition. residents of rehabilitation center of the national narcotics bureau lido,west java showed had normal salivary flow rate,normal salivary ph,however had low salivary buffering capacity.
