Objective: To analyze the literature about the different classes of RR, as well as their relationship with the specialties of orthodontics and endodontics.

Methodology: In PubMed, Science Direct, Google Schoolar searched for information with combinations of the keywords: external RR, internal RR, orthodontic treatment, endodontic treatment, epidemiology, etiology, diagnosis, manifestations and treatment.

Results: Both external and internal resorption present preference to the upper central incisor teeth. In the external reabsorption both biological and mechanical factors intervene and in the internal reabsorption the mechanical factor prevails. Cone Beam Computed Tomography (CBCT) is the most accurate diagnostic method. The treatment of external RR will depend on its etiology and the dentist's diagnostic criteria, while stopping the internal resorption process ultimately requires endodontic treatment.

Conclusion: RR has a multifactorial etiology. A correct diagnosis is essential to select the appropriate treatment plan to stop the resorption process. The CBCT is the diagnostic tool of choice for its proven effectiveness. The Calcium-enriched Mixture Cement represents a good treatment option.
