    Summary

    Surgical removal and microscopic examination revealed that sinus tracts from periapical lesions are typically lined with granulation tissue, though stratified squamous epithelium is also observed.

    Area of Science:

    • Oral pathology
    • Dental surgery

    Background:

    • Periapical lesions can lead to the formation of sinus tracts, which are pathways extending to the alveolar mucosa.
    • Understanding the histological nature of these tracts is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To investigate the histological characteristics of sinus tracts originating from periapical lesions.

    Main Methods:

    • Surgical excision of sinus tracts extending from periapical lesions to the alveolar mucosa.
    • Microscopic examination of the excised tissue specimens.

    Main Results:

    • Sinus tracts examined were found to be lined with stratified squamous epithelium in some cases.
    • More frequently, the lining of these sinus tracts consisted of granulation tissue.

    Conclusions:

    • Sinus tracts associated with periapical lesions exhibit variable histological linings.
    • Granulation tissue is the predominant lining, but stratified squamous epithelium can also be present.
