LYRA, Luciana et al. Changes in salivary composition of chemically dependent subjects. Odontología Vital [online]. 2020, n.32, pp.63-70. ISSN 1659-0775.

Chemically dependent subjects may present relevant changes in the volume and composition of salivary fluid because the secretion of the salivary glands is controlled by the parasympathetic and sympathetic system. The aim of this study was to compare the salivary concentration of total proteins, amylase, urea, calcium, phosphate and flow rate between chemically dependent and non-chemically dependent subjects. Saliva flow rate, calcium, phosphate, total protein, amylase and urea concentrations were measure in both groups: chemical dependent group (n=27) and control group (n=27). Saliva samples, from the chemically dependents, were taken one day before the beginning of the detoxification treatment. Statistical analysis was undertaken using t-test. The salivary flow and the urea concentration did not present statistically significant difference between the groups.

However, total proteins, amylase, calcium and phosphate concentrations were statistically higher on the chemical dependents group. Saliva composition seems to be modified by the chronic use of alcohol and illicit drugs.
