          Abstract

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

          Os componentes salivares podem sofrer variações que podem ser detectadas por análise química. O objetivo desse trabalho foi determinar as características físicas e bioquímicas da saliva de um grupo de crianças diabéticas comparadas a um grupo controle. A relação com a saúde oral também foi determinada. Vinte crianças diabéticas (3-15 anos) e 21 crianças do grupo controle (5-12 anos) foram incluídas nesse estudo. Quantidade total de proteínas, açúcares e cálcio foram determinadas por métodos colorimétricos e glicose, uréia, a-amilase e ácido fosfórico por métodos enzimáticos. Nossos resultados demonstraram que o pH ácido diminuiu o fluxo salivar e o excesso de espuma são normalmente encontrados na saliva de crianças diabéticas. O total de açúcares, glucose, uréia e proteínas foram maiores em pacientes diabéticos do que no controle enquanto o cálcio diminuiu. Essas diferenças foram confirmadas pelo teste de discriminação. As crianças diabéticas têm maiores valores de DMFT-dmft-deft and DMFS-dmfs-defs quando comparadas àquelas do grupo controle apesar do menor consumo de açúcar. Alguns componentes salivares e a diminuição do fluxo salivar podem estar envolvidos na caracterização da saúde oral das crianças diabéticas.

            Effects of glycemic control on saliva flow rates and protein composition in non-insulin-dependent diabetes mellitus.

            The objective of this study was to determine whether improvements in the level of diabetic control in a group of subjects with poorly controlled non-insulin-dependent diabetes mellitus influence salivary output and composition. Repeated whole unstimulated and stimulated parotid saliva samples were collected from diabetic patients attending an outpatient diabetes education program and a matched nondiabetic control group. Saliva was analyzed for flow rates, parotid protein concentration and composition, and amylase activity. Subjective responses to questions about salivary hypofunction were tested. There were no significant differences in whole unstimulated and stimulated parotid flow rates or stimulated parotid protein concentration and composition between diabetics and the control group. Amylase activity was higher in diabetics and decreased with improved glycemic control. Subjects reporting taste alterations had higher mean blood glucose levels than subjects with normal taste sensation. Poorly controlled non-insulin-dependent diabetes mellitus has no influence on saliva output, although amylase activity may be elevated, and there may be taste alterations.
