Cirugía endodóntica en el tratamiento de lesiones periapicales. Revisión bibliográfica.

Abstract

Conventional endodontic therapy usually has high success rates. However, some periapical lesions are refractory and do not regress. In this case, endodontic surgery may be indicated. The objective of the research was to identify the types of endodontic surgery techniques in the treatment of periapical lesions. The research was documentary, and was carried out under the parameters of a systematic literature review. The publications that were included in the results were located in the electronic databases Science Direct, PubMed, Scopus, SciELO and LILACS. In total, 20 articles published between 2010 and 2022 were included in the review. Eight of them were systematic reviews with meta-analysis, six systematic reviews without meta-analysis, five retrospective cohort studies, and one clinical trial. All about periapical surgeries, some measured the success rate, others focused on the study of materials that stimulate periapical bone regeneration. The techniques used to perform endodontic surgeries will depend on the clinical objective. They can range from surgical drainage to apical resection and retrograde filling. The scientific literature has a clear tendency to consider MTA as the most effective material used in periapical surgery to stimulate bone regeneration. Other important accessory aspects in endodontic surgery is the use of visual magnification, surgeries being more effective when supported by a tool of this type.
