    Area of Science:

    • Dentistry
    • Oral Pathology
    • Dental Materials Science

    Background:

    • Root caries is an emerging dental health problem.
    • Understanding the detailed histopathology of root caries is crucial for effective management and prevention strategies.

    Purpose of the Study:

    • To investigate the detailed histopathology of naturally occurring root caries.
    • To characterize the histological zones and features of root caries lesions.
    • To evaluate the utility of different microscopy techniques in studying root caries.

    Main Methods:

    • Fifty extracted human teeth with root caries were longitudinally sectioned.
    • Transmitted light microscopy, polarized light microscopy, and microradiography were employed.
    • Sections were examined with and without quinoline imbibition to enhance visualization.

    Main Results:

    • A distinct lesion body was observed in all examined root caries cases.
    • Light microscopy, especially with quinoline, revealed similar features to microradiography.
    • A structureless area below the lesion body was noted in 77% of cases with quinoline imbibition.
    • Partial radiopaque surface layers were present in nearly 80% of sections.

    Conclusions:

    • The study provides a detailed histopathological description of natural root caries.
    • Quinoline imbibition enhances the visualization of root caries lesion extent and features.
    • Findings contribute to developing model systems for evaluating root caries interventions.
    • This research supports the development of strategies to address the increasing prevalence of root caries.
