Apical root resorption: classification, diagnostic approach, therapeutic management

In clinical practice, cases of root resorption in one or more teeth are often encountered. In primary teeth, this condition is not clinically significant; however, in permanent teeth, it is an abnormality. This descriptive review will address all parameters related to the pathological condition of apex root resorption, including its etiology, prevalence, diagnosis, clinical significance, therapeutic approach, and classifications proposed by various authors over time. These classifications are linked to the etiology, location, and histological features of apex root resorption. In contrast, therapeutic management is associated only with the cause of its onset. This study aims to provide clinicians with a tool to distinguish among various pathological entities and manage them effectively. Accurate diagnosis and proper prognosis are crucial for guiding the practitioner toward personalized management and appropriate treatment.
