    Summary

    Generalized scleroderma causes significant morphological and mineral changes in teeth, including altered calcium, phosphorus, and magnesium levels. These findings highlight dental implications of systemic sclerosis.

    Area of Science:

    • Oral pathology
    • Rheumatology
    • Biomineralization

    Background:

    • Generalized scleroderma is an autoimmune disease affecting connective tissues.
    • Dental manifestations in scleroderma patients are not fully understood.
    • Scleroderma can impact mesenchymal tissues, potentially affecting tooth structure.

    Purpose of the Study:

    • To investigate morphological and microanalytic changes in teeth from patients with generalized scleroderma.
    • To identify specific alterations in hard dental tissues due to scleroderma.
    • To analyze the elemental composition of dentine in scleroderma patients.

    Main Methods:

    • Morphological examination of longitudinal and cross-ground tooth sections using light and scanning microscopy.
    • Microanalytic examination of longitudinal tooth halves utilizing X-ray microprobe analysis.
    • Analysis of teeth extracted for stomatological reasons from individuals with generalized scleroderma.

    Main Results:

    • Morphological changes of mesenchymal origin were observed in the hard tissues of teeth.
    • Significant deviations in calcium and phosphorus content were detected.
    • Absence of magnesium in dentine and a distinct decrease in the calcium-phosphorus ratio were noted.

    Conclusions:

    • Generalized scleroderma induces significant morphological alterations in tooth hard tissues.
    • Scleroderma affects the mineral composition of dentine, notably reducing calcium and phosphorus levels and eliminating magnesium.
    • These dental changes underscore the systemic impact of scleroderma on mesenchymal tissues.
