The parotid flow rate, buffering capacity and inorganic components in
saliva from 17 children with juvenile recurrent parotitis (JRP) in per
iods free of symptoms and in healthy controls of the same number, sex
and age were analysed after gustatory stimulation with 1%, 2% and 6% c
itric acid. There was a great individual variation in all analysed var
iables in the JRPs, as well as in the controls. The now rate, the buff
ering capacity of saliva and the ion concentration of phosphate were s
ignificantly lower for the JRP-children than for the controls, while t
he 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.
