Periapical surgery.

J M Hirsch, U Ahlström, P A Henrikson

    International Journal of Oral Surgery

    Summary
    This summary is machine-generated.

    Periapical surgery outcomes depend on factors like lesion extent and root filling quality. Histopathology of biopsies did not predict healing success in this study.

    Area of Science:

    • Dentistry
    • Oral Surgery
    • Endodontics

    Background:

    • Periapical surgery is a common endodontic procedure to treat persistent periapical lesions.
    • Predicting healing outcomes after periapical surgery is crucial for patient management and treatment planning.

    Purpose of the Study:

    • To evaluate the influence of preoperative, operative, and postoperative factors on healing after periapical surgery.
    • To assess the impact of different surgical techniques on treatment success.
    • To determine if histopathological diagnosis of biopsied tissue correlates with healing outcomes.

    Main Methods:

    • Retrospective study of 572 teeth treated with periapical surgery.
    • Statistical analysis using the AID method and conventional cross-classification.

  • Evaluation of factors including lesion extent, operation method, root filling quality, patient age, and bone status.

    • Main Results:

    • Key factors influencing healing included lesion extent, surgical technique, surrounding bone quality, orthograde root filling quality, patient age, and buccal marginal bone.
    • Surgical method was significant in large lesions with inadequate root fillings and in treating inflamed cysts.
    • Histopathological diagnosis of biopsied tissue showed no definitive prognostic value for healing.

    Conclusions:

    • Healing after periapical surgery is multifactorial, influenced by various clinical and radiographic parameters.
    • The choice of surgical technique and the quality of root canal obturation are critical for successful outcomes, especially in complex cases.
    • Histopathological findings from biopsies do not reliably predict the healing potential of periapical lesions.
