Avaliação de relação pH, fluxo salivar e amilase salivar em pacientes com diabetes tipo II.

Abstract

Diabetes mellitus is a metabolic disease characterized by high blood glucose levels due to changes in insulin action and / or secretion and can act as a modifying factor in oral cavity diseases, causing salivary flow, pH and salivary amylase oscillations, affecting protective capacity of saliva, which can cause an increase in number of cavities, periodontal disease, among others. This study aimed to evaluate the relationship of type II diabetes with variations in pH, salivary flow, salivary amylase and was performed with 94 people, where 44 belonged to the diabetic group and 50 to the non-diabetic group. Both groups were cared by the family health program in Patos, Paraíba. Saliva collection was performed using the modified Navazesh method with stimulated flow, where pH, salivary flow and salivary amylase activity were analyzed. It was observed, according to the results obtained, that the diabetic group had a mean age of 62.66 ± 1.90 years and the control group of 36.10 ± 1.90 years. Regarding the distribution by gender, in the diabetic group, 61.36% were females and 38.63% to the male gender. In the control group, the female gender presented a percentage of 62% and the male gender 38%. The capillary glycemia of the diabetic group was significantly higher (205.5 ± 13.04 mg / dl) than the control group (100.9 ± 1.27 mg / dl). The salivary flow of the diabetic group (0.50 ± 0.05 mL / min) was not significantly different in relation to the control group (0.53 ± 0.03 mL / min). The pH of the diabetic group (7.0 ± 0.08) was not significantly higher than the control group (6.9 ± 0.05), as well as salivary amylase from the diabetic group (743.4 ± 18.63 U / Dl) also did not present significant changes in relation to the control group (769.8 ± 1.07 U / dl). Thus, it was concluded that diabetes does not lead to salivary changes in these parameters.
