Nuclear analysis accurately measures fluorine in teeth, revealing higher concentrations in healthy incisors than molars. This research aids in understanding dental tissue fluorine distribution.

Area of Science:

  • Nuclear Physics
  • Biomaterials Science
  • Dental Research

Background:

  • Fluorine is crucial for dental health, strengthening enamel and preventing decay.
  • Accurate measurement of fluorine content and distribution in dental tissues is essential for understanding its effects.

Purpose of the Study:

  • To quantify fluorine concentration and depth distribution in human dental tissues using nuclear analysis.
  • To compare fluorine levels between different types of healthy teeth and between healthy and pathological teeth.

Main Methods:

  • Utilized high-energy proton beams for nuclear reactions to detect alpha particles and gamma rays emitted from fluorine nuclei.
  • Employed a proton probe (500 µm diameter) for precise measurement of fluorine distribution in dental enamel and cross-sections.

  • Achieved high sensitivity (0.1 mg/g) and depth resolution (0.1–0.3 µm) for fluorine atom analysis.

    • Main Results:

    • Systematic increase in fluorine concentration observed in healthy incisor enamel (1–3 mg/g) compared to molar enamel (0.5–1 mg/g).
    • Demonstrated the capability to determine depth distribution of fluorine atoms up to 5 µm within dental tissues.
    • Established a basis for comparing fluorine content in healthy versus pathological dental samples.

    Conclusions:

    • Nuclear analysis provides a sensitive and precise method for evaluating fluorine in dental tissues.
    • Incisors exhibit higher natural fluorine concentrations than molars, suggesting potential differences in their susceptibility to demineralization.
    • The findings contribute to a better understanding of fluorine's role in dental health and disease.
