Cusps or no cusps--that is not the question.

P Kirveskari

    Journal of Oral Rehabilitation
    |October 1, 1979

    Summary
    This summary is machine-generated.

    Current dental views on tooth cusps vary, but evidence suggests their importance in oral health is diminishing due to cultural evolution. Restoring cusps or prophylactic grinding lacks a rational basis, advocating for minimal intervention.

    Area of Science:

    • Dentistry
    • Oral Health
    • Dental Morphology

    Background:

    • The significance of cusps in oral health is debated, with approaches ranging from meticulous restoration to prophylactic grinding.
    • Tooth cusp morphology and arrangement are linked to masticatory function and the swallow reflex.

    Purpose of the Study:

    • To evaluate the current understanding of cusp significance in oral health.
    • To assess the rationale behind cusp restoration and prophylactic grinding in modern dentistry.

    Main Methods:

    • Literature review and analysis of current dental practices and theories regarding occlusal morphology.
    • Evaluation of the impact of cultural evolution and industrialization on masticatory function and tooth wear.

    Main Results:

    Related Experiment Videos

    • The adaptive value of efficient mastication has decreased with cultural evolution, leading to reduced functional tooth wear.
    • Restoring cusps for maximum structural efficiency lacks a rational basis due to changed function.
    • Occlusal interferences can negatively impact the swallow reflex, suggesting a need for specific occlusal adjustments.

    Conclusions:

    • Prophylactic grinding of teeth lacks a rational basis due to altered oral environments and function.
    • It is advisable to remove only harmful occlusal factors and preserve natural tooth morphology whenever possible.
