Longevity of endodontically treated teeth and restored with metalics and of glass fiber post: an integrative literature review

Abstract

OBJECTIVE: Review the literature in an integrative way, regarding a clinical longevity of endodontically treated teeth restored with fiberglass and metallic pins and with fixed crowns, based survival factors and failure mode. METHODOLOGY: A search was carried out in the Lilacs and Pubmed databases, with the following descriptors: dental restoration (dental restoration; restauración dental), dental pins (dental pins; pins dentales), clinical study (clinical study; estudio clínico). The inclusion criteria were: articles that addressed the variables of clinical longevity, survival rate and failure mode of metallic pins and fiberglass, in Portuguese, English and Spanish, published between 2010 and 2020, such as clinical trials with or without randomization and systematic reviews with or without meta-analysis. And, the exclusion criteria were: narrative literature reviews, clinical cases, in vitro and silico studies , letters to the editor and opinion articles. RESULTS: Combining the search methods, 06 articles were identified, of which 04 articles were randomized clinical trials and 02 articles were systematic reviews. The included studies show a high level of scientific evidence. FINAL CONSIDERATIONS: The present integrative literature review, regarding the clinical longevity of teeth endodontically treated and restored with metal and fiberglass pins, observed that the clinical results are still conflicting in relation to the factors of survival and failure mode. And that, the remaining coronary structure seems to be more important for the success of the rehabilitation than the material of the pin, however the supporting evidence is limited.
