Abstract
Introduction
Radiographic findings in periradicular areas are repeatedly associated with infected root canal systems. Although non-odontogenic lesions in teeth are reported to be low, they often mimic periapical pathoses, and consequently, histopathologic examinations after surgical revisions are nurtured.
Methods
Biopsies submitted to the College of Dentistry between 2003 and 2021 were reviewed. Clinicopathological characteristics were collected, including age, sex, medical history, location, sensibility tests, and clinic impressions from each specimen. Histopathologic diagnosis and gross description were also part of our database.
Results
A total of 72,055 pathology reports were reviewed, of which 10,031 lesions (13.9%) met the criterion of being intraosseous lesions at the periradicular area. Among those 10,031 lesions, 7.94% (n=796) were of non-endodontic origin, 7,153 were documented as non-vital, and 2.36% (n=169) of these non-vital teeth were diagnosed with a non-endodontic origin. A total of 5,707 lesions were obtained from surgeries within the periapical tissues, primarily performed by endodontists (94.02%). Non-endodontic lesions were reported in 1.09% of the cases. Odontogenic keratocyst (OKC) was the most common non-endodontic diagnosis, followed by nasopalatine duct cyst and benign fibro-osseous lesion, respectively.
Conclusions
Pathologic findings of the periradicular tissues are not always from endodontic origin. The probability of encountering non-endodontic lesions is almost 8%. Even in clinically reported teeth with Pulp necrosis, 1-3% of biopsies were confirmed as non-endodontic lesions.
