Abstract
Introduction
autism spectrum disorder is a neurodevelopmental condition that affects the establishment of bonds and communication. Dental care is more difficult for people with this disorder, because in addition to communication difficulties, non-cooperation with respect to oral hygiene and continuous use of medication are common. Greater predisposition to caries, as well as alterations in the flow and concentration of salivary proteins were reported in these individuals.
Objective
considering that sex can affect salivary flow and protein concentration, our objective was to analyze these parameters in the saliva of children with autism.
Material and method
total unstimulated saliva was obtained from 12 boys and 12 girls aged between 5 and 15 years, with the aid of a catheter, after 2 hours of fasting and oral hygiene. Salivary flow was determined by estimating the mass of saliva. Total protein was determined in the supernatant obtained after centrifugation at 10,000 x g, for 10 minutes, by the Lowry method, with bovine albumin as standard. The results are expressed as mean and standard deviation. The data were submitted to the Shapiro-Wilk and Mann Whitney tests, with a significance level of 5%.
Result
salivary flow values for boys (0.3555 ± 0.24 ml/min) and girls (0.2522 ± 0.1727 ml/min), and protein values for boys (1.430 ± 0.7480 mg/mL) and girls (1.075 ± 0.3702 mg/mL) were not significantly different between sexes.
Conclusion
in children with autism spectrum disorder, sex does not influence unstimulated flow and salivary protein values.
