ABSTRACT

The aim of this article was to establish the prevalence of root resorption in endodontically treated teeth, by means of cone-beam computed tomography (CBCT). Material and method. We analysed 609 endodontically treated teeth from patients who visited two private dental offices over a period of 3 years (2020-2023). We searched for any sign of root resorption, internal, external and apical. Results. The overall prevalence of root resorption in root canal treated teeth was 6.57%. Of these, 82.5% had apical periodontitis (AP). 67.57% were external apical inflammatory resorption, 21.62% were external cervical resorption and 18.92% were internal resorption. Conclusions. Root resorption of permanent teeth is an unfavourable condition, which can involve endodontically treated teeth. The most frequent form of resorption was external apical. Posterior teeth presented the highest percentage of resorptions. From the prognosis point of view, it is crucial that they are diagnosed in the early stages. CBCT has an invaluable role in accurately diagnosing this condition.
