Evaluación del Inventario de Xerostomía en relación al flujo salival en los pacientes que asisten a la Clínica del Adulto Mayor de la Facultad de Odontología de la Universidad Santo Tomás de Bucaramanga

Abstract

Introduction: Xerostomia is considered as the dry mouth sensation that may appear in conjunction with decreased salivary volume. Objective: To evaluate the inventory of xerostomia in relation to salivary flow in patients attending the elderly clinic of the school of Dentistry of the Universidad Santo Tomás de Bucaramanga. Methods: An evaluation study of diagnostic technology was carried out in the patients of the Senior Adult Clinic, evaluating the sociodemographic variables, the inventory of Xerostomia and Burning Buccal and the test of stimulated and unstimulated salivary flow (sialometry). An informed consent was applied and statistical analysis was performed in STATA 14.0. Results: 66.99% of the participants were women, the average age of the group was 67.4 years and the majority of the population belonged to Stratum 3 (36.89%). In stimulated and unstimulated salivary flow tests, the level most frequently presented was normal. The average of the Xerostomia inventory score was 22.6 DS of 7.82 and the median was 21with RI (17-28). There was a negative correlation (-0.2112) between the Xerostomia score and the unstimulated salivary flow (P = 0.03).In addition, the cutting point of the xerostomia inventory with greater ROC (0.67) was 22 in the very low non-stimulated salivary flow test and the Sialometría test with greater area under the curve (0.71) was the very low unstimulated salivary flow. Conclusions: From the score 22 in the inventory of Xerostomia, could discriminated as a screening test of the presence of xerostomia and then suggest the test Sialometría considering the classification of salivary flow normal and very low, as a diagnostic test.
