Capacidade de vedação dos seladores endodônticos biocerâmicos versus convencionais: revisão sistemática de estudos in vitro

Resumo original em inglês

O que aconteceu

Bioceramic sealers are contemporary bioactive endodontic biomaterials that have gained considerable attention because of their favorable physicochemical and biological properties, including bioactivity and biocompatibility. These characteristics may extend their function beyond passive sealing; however, studies comparing their sealing performance with conventional sealers have reported inconsistent findings.

To systematically review the available in vitro evidence comparing the sealing ability of bioceramic and conventional endodontic sealers.

A systematic literature search was performed in PubMed, Scopus, Web of Science, and Google Scholar to identify full-text in vitro experimental studies published in English between January 2000 and April 2026. The search strategy used the terms (sealing effectiveness OR sealing ability) AND (bioceramic sealers OR conventional sealers). Study selection was conducted in accordance with the PRISMA 2020 guidelines. Risk of bias was assessed using a structured assessment based on domains adapted from the Cochrane RoB 2 framework for laboratory studies.

O que encontraram

Twelve in vitro controlled laboratory studies involving 831 specimens met the inclusion criteria. Seven studies (58%) reported findings favoring bioceramic sealers, four studies (33%) favored conventional sealers, and one study (8%) found no statistically significant difference between groups. No consistent association was identified between obturation technique and sealing outcomes.

Por que isso importa

Most included studies reported superior sealing ability with bioceramic sealers compared with conventional sealers. However, the findings were not uniform across all studies. Further well-designed in vivo investigations are required to determine whether these in vitro observations translate into clinical benefit.
