Susceptibility to dental caries.

R R Steinman, J Leonora, J M Tieche

    Australian Dental Journal
    |August 1, 1979
    PubMed
    Summary

    The dental pulp significantly influences caries susceptibility, while saliva plays a minor role in caries resistance. Hormonal factors from salivary glands may affect pulpal activity and tooth decay.

    Area of Science:

    • Dental research
    • Caries susceptibility and resistance
    • Oral health

    Background:

    • Dental caries is a multifactorial disease influenced by tooth structure, bacteria, diet, and host factors.
    • The roles of the dental pulp and saliva in modulating caries risk are not fully elucidated.
    • Understanding these roles is crucial for developing effective caries prevention and management strategies.

    Purpose of the Study:

    • To evaluate the distinct roles of the dental pulp and saliva in determining caries susceptibility and resistance.
    • To investigate the influence of pulpal activity on caries development.
    • To identify potential salivary factors affecting pulpal activity in relation to caries.

    Main Methods:

    • The study employed a combination of endodontic treatment (to alter pulp status) and desalivation (to reduce salivary influence).
    • Carried out experimental manipulations to isolate the effects of pulp and saliva.
    • Evaluated changes in caries susceptibility and resistance following these interventions.

    Main Results:

    • Evidence strongly suggests the dental pulp plays a major role in caries susceptibility.
    • Pulpal activity was found to be modified by hormonal factors originating from the salivary glands.
    • Saliva demonstrated a comparatively minor role in providing resistance against caries.

    Conclusions:

    • The dental pulp is a key determinant of caries susceptibility.
    • Salivary gland secretions, potentially hormonal, influence pulpal activity and caries risk.
    • Saliva's contribution to caries resistance is limited compared to the pulp's role.
