Laboratory study of fluoride impregnated toothpicks
Scandinavian Journal of Dental Research
|December 1, 1981
Summary
Wooden toothpicks can be impregnated with sodium fluoride (NaF) for fluoride delivery. Rapid fluoride release from these toothpicks into saliva suggests potential for clinical applications in dental caries prevention.
Area of Science:
- Dental materials science
- Fluoride chemistry
- Preventive dentistry
Background:
- Fluoride toothpastes and rinses are effective in preventing dental caries.
- Novel methods for fluoride delivery are continuously being explored to enhance caries prevention strategies.
Purpose of the Study:
- To investigate the feasibility of using wooden toothpicks as a vehicle for fluoride delivery.
- To quantify the uptake and release kinetics of fluoride from impregnated toothpicks.
Main Methods:
- Wooden toothpicks were immersed in sodium fluoride (NaF) or amine fluoride solutions.
- Fluoride uptake was measured, and release into water and artificial saliva was monitored.
- Fluoride concentrations in saliva during simulated use were analyzed.
Main Results:
- High initial rates of fluoride uptake were observed, with clinically relevant amounts achieved in approximately 5 minutes.
- Rapid fluoride release occurred when toothpicks were exposed to water or saliva.
- Salivary fluoride concentrations ranged from 0.1 to over 50 parts/10^6 F, depending on the impregnation method.
Conclusions:
- Fluoride-impregnated toothpicks demonstrate efficient fluoride uptake and release characteristics.
- The study highlights the potential clinical utility of fluoride-delivering toothpicks for caries prevention.
- Further research into the clinical application of these fluoride-impregnated toothpicks is warranted.
