Scanning microscopy of cervical erosion.

J M Brady, R D Woody

    Journal of the American Dental Association (1939)
    |April 1, 1977
    PubMed
    Summary

    Cervical erosion affects 5.3% of dentists, with premolars most impacted. Two distinct erosion patterns suggest different underlying causes, one more destructive than the other.

    Area of Science:

    • Dental Science
    • Oral Pathology

    Background:

    • Cervical erosion is a significant dental concern.
    • Understanding its prevalence and characteristics is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To investigate the prevalence and patterns of cervical erosion in a cohort of dentists.
    • To characterize the morphology of cervical erosion lesions using advanced imaging techniques.

    Main Methods:

    • Examination of dentitions from 900 dentists for cervical erosion.
    • Creation of epoxy resin models from silicone impressions of eroded surfaces.
    • Analysis of models using scanning electron microscopy and light microscopy on cross-sections.

    Main Results:

    • Observable erosion found in 5.3% (48 individuals) of the dentists.
    • Most severe erosion occurred on first premolars (62%), followed by second premolars (19%), cuspids (12%), and first molars (6%).
    • Two distinct erosion patterns identified: angular and deep (68%) and rounded and shallow (32%).

    Conclusions:

    • Cervical erosion presents with varied prevalence and specific tooth site predilection.
    • The identified distinct erosion morphologies suggest the involvement of at least two different etiological mechanisms.
    • Further research into these mechanisms is warranted for effective prevention and management strategies.
