Prognosis and Histological Diagnosis of Periapical Lesions treated by Periapical Surgery

Abstract

Abstract:

Background: The objective of this research was to investigate the samples obtained from periapical surgery and their histological diagnosis as well as their radiographic dimensions.

Material and methods: After performing tissue curettage, a total of 40 biopsies were taken during periapical surgery and subjected to histological examination, resulting in diagnoses of granuloma, cyst, or scar tissue. The size of the lesions was measured both before the surgery and after 1 year also. The progression was evaluated at a year mark post-surgery, following the criteria established by von Arx and Kurt. Statistical analysis included assessing inter-variable correlations using analysis of variance, followed by Tukey test, and determining the Pearson coefficient.

Results: The study involved 40 participants, consisting of 10 females and 30 males, with an average age of 35.4 years (ranging from 16 to 54 years). Among the samples, 18% were identified as apical scar, 72% as granulomas, and 10% as cystic lesions.

Conclusion: Cysts, along with large abnormalities, exhibit the least favorable progression, and the prognosis for periapical lesions is contingent upon the specific lesion type and its radiographic dimensions.
