RESUMENObjetivoDeterminar el efecto de la aparatología ortodóntica fija sobre el flujo y viscosidad salival.Material y métodosSe evaluaron muestras salivales de 44 pacientes de ambos sexos entre 10 a 34 años de edad; de Trujillo, Perú, 22 de ellos recibieron aparatología ortodóntica fija y los otros 22 no la recibieron y sirvieron como control. Se obtuvieron muestras para la evaluación del flujo y viscosidad salival antes y al mes de instalada la aparatología ortodóntica fija. Para cuantificar el flujo salival se cronometraron cinco minutos para obtener saliva en un tubo de ensayo y luego hacer la medición empleando una probeta milimetrada de 10mL. Para medir la viscosidad se recolectaron 5mL de saliva y luego fue calculada mediante la fórmula de la viscosidad relativa (VR = tiempo de 5mL de saliva/tiempo para 5mL de agua) usando un viscosímetro. Para la comparación entre y flujo y viscosidad salival antes y al mes se empleó la prueba de Wilcoxon debido a que los datos no siguieron distribución normal; se consideró un nivel de significancia del 5%.ResultadosSe encontraron diferencias estadísticamente significativas (p < 0.05) en el flujo y la viscosidad salival entre antes y al mes de instalada la aparatología ortodóntica fija, apreciándose un aumento del flujo salival y una disminución de la viscosidad salival.ConclusiónEl uso de aparatología ortodóntica fija afecta el flujo y viscosidad salival al mes de su instalación.ABSTRACTObjectiveTo 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.
