Area of Science:

  • Oral Health
  • Dental Caries Prevention
  • Pharmacokinetics

Background:

  • Fluoride's crucial role in preventing dental caries is well-established.
  • Understanding fluoride elimination from the oral cavity is complex.
  • Accurate modeling aids in optimizing fluoride delivery for caries prevention.

Purpose of the Study:

  • To simulate the physiological process of fluoride elimination from the oral cavity.
  • To calculate fluoride concentrations in saliva and dental plaque over time.
  • To validate a computational model against in vivo findings.

Main Methods:

  • Developed a Pascal program for simulation on IBM-compatible microcomputers.
  • Input parameters included fluoride amount, salivary stimulation, and flow rates.
  • Modeled intestinal absorption and excretion, and plaque diffusion.

Main Results:

  • The program calculated time-dependent fluoride concentrations in saliva.
  • Dental plaque fluoride levels were determined via diffusion modeling.
  • Simulated results closely matched in vivo experimental findings.

Conclusions:

  • The developed computational model effectively simulates oral fluoride dynamics.
  • This simulation provides valuable insights into fluoride's behavior in the oral cavity.
  • The model supports research and application in dental caries prevention strategies.
