Salivary characteristics of diabetic children.

Salivary components may suffer variations that can be detected by chemical determinations. The aim of this work was to determinephysical and biochemical characteristics of the saliva of a group of diabetic children compared to those of a control group. Relation tooral health indices was also determined. Twenty diabetic children (3-15-years-old) and 21 control children (5-12-years-old) wereincluded in this study. Total proteins, sugars and calcium were determined by colorimetric methods, and glucose, urea, α-amylase andacid phosphatase by enzymatic methods. Our results demonstrated that acidic pH, diminished salivary flow rate and excess foam areusually present in saliva of diabetic children. Total sugars, glucose, urea and total proteins were greater in diabetic patients thancontrols, while calcium values were decreased. These differences were confirmed by the discrimination test. Diabetic children havehigher DMFT-dmft-deft and DMFS-dmfs-defs values compared to those of the control children despite their lower sugar intake. Somesalivary components in addition to the diminished flow rate could be involved in the characterization of the oral health state of diabeticchildren.Key Words: diabetes, children, saliva, oral health.
