Testing for a Fluoride Toothpaste Utilization Formula: Does Rinsing after Toothbrushing Affect Dental Caries Prevention?

Abstract

Background and Objective: Global levels of dental caries have declined since the introduction of fluoridated toothpastes, but caries prevalence is still seen to be increasing in developing nations. The actual utilization and effect of fluoridated toothpaste in caries prevention is difficult to assess. A Fluoride Toothpaste Utilization Formula, which considers the amount of toothpaste used during brushing, frequency of use, and a rinsing variable to quantify the effect of rinsing after toothbrushing, was proposed to be used to evaluate fluoride utilization. This study aimed to test the proposed fluoride utilization formula.

Methodology: A cross-sectional study was done in Malolos City, Philippines and carried out multi-stage sampling to identify household health managers from two barangays (n=108) as respondents. The respondents were interviewed on their basic oral health knowledge, attitudes, and practices. Oral examinations using the Decayed, Missing, and Filled Teeth (DMFT) Index were performed on family members present during the visit.

Results: Both barangays scored way below the ideal fluoride utilization composite score of 3.6. Practically all the respondents rinsed with water after toothbrushing. The rinsing habit would greatly alter the effect of fluoride, rendering fluoride utilization less optimal even though a more-than-necessary amount of fluoride toothpaste was regularly used.

Conclusion: The fluoride toothpaste utilization score is greatly affected by the variable assigned if rinsing is done after toothbrushing. Focus on a no-rinse toothbrushing regimen must be given in oral health education programs. Further evaluation of the formula, particularly the rinsing variable, must be done to properly quantify the effects of fluoride and assess the other factors associated in toothbrushing with fluoridated toothpastes.
