Relationship of hyposalivation and xerostomia in Mexican elderly with socioeconomic, sociodemographic and dental factors.

Abstract:

:We determined the prevalence of hyposalivation and xerostomia in older Mexicans (≥60 years), and its relationship with diverse factors. A cross-sectional study was realized in elderly subjects from Pachuca, Mexico. Chewing-stimulated saliva was collected under standardized conditions and salivary flow was measured; subjects were considered to have hyposalivation if their stimulated salivary flow was less than 0.7 mL per minute. Xerostomia was evaluated by asking subjects 'Does your mouth feel dry?'. Hyposalivation was present in 59.7%, and xerostomia in 25.2% of subjects. 16.5% of subjects had both conditions. Xerostomia was present in 27.7% of subjects with hyposalivation and 21.4% of subjects without hyposalivation, but the difference was not significant (p > 0.05). Thus, 68.3% of older Mexicans had xerostomia and/or hyposalivation. Factors associated with hyposalivation were: using fewer devices in oral hygiene, lacking social benefits for retirement/pension, living in a public retirement home, brushing teeth less than twice a day and lacking teeth without dentures. None of the factors included in this study were associated with xerostomia. We concluded that several variables studied were associated with hyposalivation, but none for xerostomia. Additional research should examine the amount of hyposalivation and factors associated with hyposalivation especially in elderly with increased risk for hyposalivation.
