ObjectiveTo determine the effect of orthodontic fixed appliances on salivary flow and viscosity.Material and methodsSaliva samples from 44 patients between 10-34 years old of both genders were assessed in Trujillo, Peru. Twenty-two of them received orthodontic fixed appliances and the other 22 did not receive then and served as control. Samples for the evaluation of salivary flow and viscosity before and one month after orthodontic fixed appliances placement were obtained. To quantify salivary flow, 5minutes was clocked to obtain saliva in a test tube and then make measurements using a 10mL test tube millimeter. To measure viscosity, 5mL of saliva was collected and calculated by the formula of the relative viscosity (VR = time of 5mL saliva/time to 5mL of water) using a viscometer. For comparison of salivary flow and viscosity before and a month after the Wilcoxon test was used because the data did not exhibit a normal distribution. A significance level of 5% was considered.ResultsStatistically significant differences (p < 0.05) in salivary flow and viscosity were found before orthodontic fixed appliances placement and one month after, showing an increase in salivary flow and a decrease in salivary viscosity.ConclusionThe use of orthodontic fixed appliances affects salivary flow and viscosity month after placement
