The gigantiform salivary calculus.

G Isacsson, N E Persson

    International Journal of Oral Surgery
    |April 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Gigantiform salivary calculi can grow large, with one 3.6 cm calculus found in the Wharton duct. Microorganisms throughout the stone, including its nucleus, are a key factor in the formation of these large salivary stones.

    Area of Science:

    • Oral pathology
    • Microbiology
    • Biomineralization

    Background:

    • Salivary calculi (stones) vary greatly in size.
    • Gigantiform salivary calculi are rare, exceptionally large formations.
    • Understanding their etiology is crucial for diagnosis and treatment.

    Observation:

    • A 3.6 cm gigantiform salivary calculus was surgically removed from a 48-year-old man's Wharton duct.
    • The calculus was analyzed using histology, microradiography, and scanning electron microscopy.
    • Microorganisms, primarily thread-like, were identified throughout the calculus structure.

    Findings:

    • Histology revealed a homogeneous central nucleus and peripheral lamellation.
    • Microradiography showed dense mineralization in the nucleus and alternating mineral content in the periphery.

  • Scanning electron microscopy confirmed these structural and mineral distribution patterns.

    • Implications:

    • The presence of microorganisms, even within the calculus nucleus, is a significant etiological factor.
    • This finding aids in understanding the pathogenesis of large salivary calculi.
    • Further research into microbial roles in salivary stone formation is warranted.
