Summary

Skeletal fluorosis affects aluminum workers with prolonged fluoride exposure. Early detection is challenging due to non-specific symptoms and imaging limitations, necessitating quantitative assessment methods.

Area of Science:

  • Occupational Health
  • Skeletal Biology
  • Toxicology

Background:

  • Aluminum workers face occupational exposure to fluoride.
  • Skeletal fluorosis is a potential health risk associated with fluoride exposure.
  • Current diagnostic methods for skeletal fluorosis have limitations.

Purpose of the Study:

  • To investigate the incidence and characteristics of skeletal fluorosis in aluminum workers.
  • To evaluate the relationship between fluoride exposure duration/degree and fluorosis development.
  • To highlight diagnostic challenges and the need for improved assessment methods.

Main Methods:

  • Clinical and radiological investigations of 2,258 aluminum workers.
  • Categorization of workers based on duration of fluoride exposure (≤5 years, 6-32 years, retired).

  • Introduction of a semiquantitative assessment for early fluorosis detection.

    • Main Results:

    • A 20.2% incidence of fluorosis was observed, with most cases in pre-stages (O and OI).
    • A strong correlation was found between fluorosis occurrence and the time and level of fluoride exposure.
    • Only 1.05% of cases met Roholm's criteria for Stage I fluorosis, indicating early disease stages.

    Conclusions:

    • Skeletal fluorosis is prevalent in aluminum workers, particularly in its early, less defined stages.
    • Diagnosis is complicated by non-specific symptoms and limitations of current radiological techniques.
    • There is a critical need for quantitative methods to accurately assess osteosclerosis and bone alterations in skeletal fluorosis.
