Salivary factors in children with recurrent parotitis. Part 1: Salivary flow rate, buffering capacity and inorganic components.
The parotid flow rate, buffering capacity and inorganic components in saliva from 17 children with juvenile recurrent parotitis (JRP) in periods free of symptoms and in healthy controls of the same number, sex and age were analysed after gustatory stimulation with 1%, 2% and 6% citric acid. There was a great individual variation in all analysed variables in the JRPs, as well as in the controls. The flow rate, the buffering capacity of saliva and the ion concentration of phosphate were significantly lower for the JRP-children than for the controls, while the concentration of chloride, sodium and copper were raised (p < 0.01-0.001). No statistical differences were found for the pH, the calcium, the potassium, the magnesium and the zinc concentrations. The results suggest a longterm effect on the parotid saliva in the JRP-cases due to the disease.
