Resumen
Introducción

En personas sanas, la velocidad de flujo salival o sialometría (VFS) puede afectarse por la edad, género y ritmo circadiano. No existe evidencia de la reproducibilidad de VFS no estimulada determinada en 5 minutos, en distintos momentos del día en un mismo individuo.

Objetivos

Determinar confiabilidad de VFS no estimulada medida en 5 minutos, reproducibilidad en el tiempo y relación con rango etario y género.

Metodología

Se determinó VFS durante 15 minutos en 42 individuos clínicamente sanos, con una mediana de 45.5 (30–65) años, entre 9 y 11 AM durante dos mañanas y entre 3 y 5 PM durante la tarde del segundo día de medición. La saliva se colectó en tubos separados durante 5 minutos y durante los 10 minutos restantes. El peso de las muestras fue expresado en ml/min. Los valores entre los grupos de estudio, se compararon mediante test t de Student, ANOVA y coeficiente de correlación de Spearman.

Resultados

VFS promedio fue de 0.623±0.329 y de 0.551 ± 0.289 a los 5 y 15 minutos respectivamente (p=0.001). VFS fue mayor en hombres a los 5 y 15 minutos (p=0.001). VFS en mujeres, disminuyó al aumentar la edad. No hubo diferencias en VFS a los 5 minutos (p=0.375) y a los 15 minutos (p=0.825), en distintos días y momentos del día, en un mismo individuo.

Conclusión

VFS colectada durante 5 minutos, en un mismo individuo, presenta valores constantes en distintos días y momentos del día.

Abstract
Introduction

In healthy persons, the salivary flow rate (VFS) or sialometry can be affected by the age, the gender and the circadian rhythm. There is no evidence of the reproducibility of the non-stimulated VFS determined in 5 minutes, in different moments of the day in the same individual.

Aim

To determine the reliability of the non-stimulated VFS measured in 5 minutes, its reproducibility over time and its relation with the age range and the gender.

Methodology

VFS was determined for 15 minutes in 42 clinically healthy individuals, with a median age of 45.5 (30-65), between 9 and 11 AM in two mornings and between 3 and 5 PM in the evening of the second day of measurement. The saliva was collected in 2 separated pipes, one for the first 5 minutes and one for the 10 remaining minutes. The weight of the samples was expressed in ml/min. The values between the groups of study were compared by means of the Student's t-test, ANOVA and the Spearman's correlation coefficient.

Results

The average VFS was of 0.623 ± 0.329 and of 0.551 ± 0.289 after 5 and 15 minutes respectively (p=0.001). VFS was higher in men after 5 and 15 minutes (p=0.001). VFS in women diminished as the age increased. There were no differences in VFS after 5 minutes (p=0.375) and after 15 minutes (p=0.825), in different days and moments of the day, in the same individual.

Conclusion

VFS collected for 5 minutes in the same individual presents constant values in the different days and moments of the day.
