Survival of teeth with external cervical resorption after Internal and External Repair: A Systematic Review.

Abstract

Background: To analyze the survival rate of teeth affected by invasive cervical resorption after internal and external repair.

Material and methods: A search was conducted in PubMed/Medline, Web of Science, Embase, Scopus, the Cochrane Library, and gray literature at the DANS Easy Archive until September 2023. The selected studies were subjected to risk assessment of bias, and the quality of evidence was assessed using the Newcastle Ottawa Scale. The GRADE was used to analyze the certainty of evidence.

Results: Three articles were included in this study. The Heithersay classification was used in all included studies. Only one study has reported on the Patel classification. Different results associated with the survival of treated invasive cervical resorption elements have been reported. Two studies reported a higher survival rate in externally repaired teeth than in internally repaired teeth. Only one study reported greater survival of theeth with external cervical resorption rate in the treatment with internal repair. The studies showed strong evidence and the certainty of the evidence was classified as very low.

Conclusions: Failure rates were low in dental treatments with invasive cervical resorption for both repairs, with external repair being more promising and showing the highest survival rate in the follow-up period of at least one year. Key words:External cervical resorption, external repair, interal repair, survival rate, dental treatments.
