Total cementum removal: a realistic objective?

T J O'Leary, A H Kafrawy

    Journal of Periodontology
    |April 1, 1983

    Summary
    This summary is machine-generated.

    Total cementum removal from periodontally involved root surfaces is not clinically realistic. Even after extensive scaling, residual cementum remained on all tested teeth, particularly in apical areas.

    Area of Science:

    • Periodontology
    • Dental Morphology

    Background:

    • Periodontal disease leads to attachment loss and necessitates root surface debridement.
    • Complete removal of cementum during periodontal therapy is often considered ideal but its feasibility is debated.

    Purpose of the Study:

    • To evaluate the clinical realism of achieving total cementum removal from periodontally involved root surfaces.
    • To assess if different scaling instruments impact residual cementum levels.

    Main Methods:

    • 36 periodontally diseased teeth were extracted and divided by age groups.
    • Teeth underwent 50 planing strokes with Jacquette scaler, Gracey curet, or Indiana University curet after calculus removal.
    • Histological analysis of decalcified, sectioned, and stained tooth surfaces was performed.

    Main Results:

    • None of the 34 evaluated teeth showed complete cementum removal from the tested proximal surfaces.
    • No significant difference in residual cementum was observed among the tested instruments.
    • Greater amounts of residual cementum were consistently found in apical regions of the root surfaces.

    Conclusions:

    • Total cementum removal from periodontally involved root surfaces is not achievable with current instrumentation.
    • The presence of residual cementum, especially apically, is a consistent finding regardless of instrument type.
    • Further research may be needed to understand the clinical implications of residual cementum in periodontal therapy.
