Biological aspects and treatment of external replacement resorption: literature review

Paela Monisa Rocha da Silva, Edson Dias Costa Junior

Replacement external root resorption consists in the replacement of dental structure into bone tissue. The current consensus is that there is no relevant therapy for that process. A Literature review focused on therapeutic protocol used on traumatized teeth and its effects about the replacement external root resorption is presented. For this purpose, English scientific articles were attached by using the data bases Pubmed Central, Scopus, Embase Medline, Ovid and Cochrane, with the keywords: Tooth Resorption, Root Resorption, Tooth Injuries, Root Canal Therapy, Ankylosis. Studies demonstrated that ankyloses and the replacement external root resorption were developed in dental surfaces independently from the medicine used on the root’s interior. Teeth treated with calcium hydroxide and gutta percha showed greater predominance of bone deposition. Intracanal corticosteroids showed promising results, where it was observed favorable repair and having less rates of replacement external root resorption. Articles that relate interceptive attempts against the replacement resorption process were not founded. Despite its frequency, attempts to control the installed process are relevant, considering that the treatment absence results on the worst consequence as possible, the tooth loss.

Keywords: Root Resorption. Tooth Resorption. Tooth Injuries. Root Canal Therapy. Ankylosis.
