Stimulated salivary flow rate and oral health status

Abstract

This study examined the relationship between stimulated salivary flow rate and oral health status in an adult population. Multinomial multivariate logistic regression analysis was used to examine the associations of salivary flow rate with dental caries status and periodontal status at the individual level among 2,110 Japanese adults with ≥10 teeth. Then, a spline model was used to examine the nonlinear relationship between salivary flow rate and teeth with dental caries or periodontal disease in multilevel analysis. Odds ratios were calculated for a 1.0-mL/min reduction in salivary flow rate at a point. After adjusting for confounding variables, participants with a flow rate ≤3.5 mL/min had significantly higher odds ratios for high caries status, and participants with a flow rate ≤1.4 mL/min had a higher odds ratio for broad periodontal disease, than did those with a flow rate >3.5 mL/min. In spline models, the odds ratio for teeth with dental caries or periodontal disease increased with reduced saliva secretion. The present findings suggest that decreased saliva secretion affects both dental caries and general periodontal health status.

Quantification of the salivary volume flow rate in the parotid duct using the time‐spatial labeling inversion pulse (Time‐SLIP) technique at MRI: A feasibility study

“…There is great variability in the interindividual salivary VFR; the accepted range of a normal VFR for stimulated saliva production ranges from 2000 to 70,000 mm 3 /10 min. 2,28,29 The mean VFR in our human study was 8760 mm 3 /10 min and therefore within the reported range. Moreover, the VFR (minimum VFRmax: 2850 mm 3 /10 min) in all volunteers was higher than the minimum accepted VFR.…”

“…The mean VFR over 10 minutes, calculated from mean VFRmax, was 8760 mm 3 . There is great variability in the interindividual salivary VFR; the accepted range of a normal VFR for stimulated saliva production ranges from 2000 to 70,000 mm 3 /10 min . The mean VFR in our human study was 8760 mm 3 /10 min and therefore within the reported range.…”

Salivary nitric oxide, Simplified Oral Hygiene Index, and salivary flow rate in smokers and non-smokers: a cross-sectional study

“…The increase of salivary flow is much more effective in neutralizing and buffering food acids. The study by Shimazaki et al reveals that decreased saliva secretion affects both dental caries and general periodontal health status 21 . Ahmad et al also reported that hyposalivation due to the low saliva flow rate related to more caries in the aging population and significantly poor of the quality of life 22 .…”

Correlation of Unstimulated and Stimulated Salivary Flow Rate in Chronic Periodontitis

“…Though, the actual information regarding the conditions associated with the production of the saliva is limited. 5 Using the salivary flow rate, saliva's quantitative state is determined. The salivary flow rate is the measurement of production of the saliva in a given period of time by the salivary gland which is expressed usually in grams per minute or milliliters per minute (g/min or mL/min).…”
