Estudio piloto sobre el diagnóstico y factores relacionados con la hiposialia en pacientes con xerostomía en una clínica universitaria / Pilot study on diagnosis and related factors to hyposialia in xerostomic patients at a university clinic

La xerostomía es una sensación subjetiva de boca seca que puede acompañarse de disminución de la cantidad de saliva o no. La hiposialia es la disminución del flujo salival medido mediante una sialometría. El objetivo del estudio fue definir el porcentaje total de pacientes con hiposialia real en un grupo de pacientes con xerostomía y analizar las diferencias existentes entre los pacientes con xerostomía asociada a hiposialia y los pacientes con xerostomía subjetiva. 28 pacientes que referían xerostomía formaron parte del estudio entre noviembre y marzo de 2020-2021 en la Policlínica de la Universidad Europea de Madrid. Se completó una exhaustiva historia médica, se cumplimentaron tres cuestionarios: Xerostomy Inventory, Perceived Stress Scale y OHIP-14, y se realizó una sialometría no estimulada durante cinco minutos. El análisis de los datos se realizó con el paquete estadístico Stata IC v. 14. El 82% del total de los pacientes que referían boca seca eran mujeres con una edad media de 59,14 años. Menos de la mitad de los pacientes (46%) presentaban hiposialia objetivada mediante la sialometría. Había más pacientes portadores de prótesis dentales en el grupo que sufría de hiposialia respecto al grupo con flujo salival normal. Ambos grupos mostraron un número similar de enfermedades y medicamentos xerostomizantes. En cuanto a los cuestionarios cumplimentados, no hubo diferencia significativa en los resultados de ambos grupos. (AU)

Xerostomia is a subjective sensation of dry mouth that may or may not be accompanied by a decrease in the amount of saliva. Hyposialia is the reduction in salivary flow measured by a sialometry. The aim of the study was to define the total percentage of patients with true hyposialia in a group of patients with xerostomia and to analyze the differences between patients with xerostomia associated with hyposalia and patients with subjective xerostomia. 28 patients who referred xerostomia were part of the study between November and March 2020-2021 at the Polyclinic of the European University of Madrid. A comprehensive medical history was fulfilled, three questionnaires were completed: Xerostomia Inventory, Perceived Stress Scale, and OHIP14, and unstimulated sialometry was performed for five minutes. Data analysis was performed with the Stata IC v. 14. 82% of the total patients who reported dry mouth were women with a mean age of 59.14 years. Less than half of the patients (46%) had hyposialia as evidenced by sialometry. There were more patients with dental prostheses in the group suffering from hyposialia compared to the group with normal salivary flow. Both groups showed a similar number of xerostomizing diseases and drugs. Regarding the completed questionnaires, there was no significant difference in the results of both groups. (AU)

Pilot study on the diagnosis of and factors related to hyposialia in patients with xerostomia at a university clinic

Xerostomia is a subjective sensation of dry mouth that may or may not be accompanied by a decrease in the amount of saliva. Hyposialia is a reduction in salivary flow, as measured by sialometry. The aims of the study were to establish the total percentage of patients with actual reduced saliva flow (hyposialia) in a group of patients with perceived reduced saliva flow (xerostomia) and analyse the differences between patients with xerostomia associated with hyposalia and patients with subjective xerostomia. 28 patients with xerostomia were part of the study between November and March 2020-2021 at the Polyclinic of the European University of Madrid. A comprehensive medical history was prepared, 3 questionnaires were completed (Xerostomia Inventory, Perceived Stress Scale and OHIP- 14) and unstimulated sialometry was performed for 5 minutes. Data analysis was performed with the Stata IC v 14 statistics program. 82% of the total patients who reported dry mouth were women, with a mean age of 59.14 years. Less than half of the patients (46%) had hyposialia as evidenced by sialometry. There were more patients with dental prostheses in the group suffering from hyposialia compared to the group with normal salivary flow. Both groups showed a similar number of xerostomising disorders and drugs. There were no significant differences between either group regarding the completed questionnaires. (AU)
