Introduction: Endodontic treatment include different phases like controlling the growth of microorganism, thorough cleaning and shaping and fluid tight seal. Sealer plays an important role in root canal treatment. Sealer fills the space between filling material and dentin. Sealer also acts as a lubricant. Sealer has ability to fill the spaces and prevent microleakege from the root canal. Mineral Trioxide Aggregate (MTA) is a calcium silicate based sealer which has high radiopacity, low solubility and good antibacterial activity.
Aim: To evaluate pushout bond strength of MTA as a root canal sealer.
Materials and Methods: In this systematic review, the studies were chosen based on inclusion and exclusion criteria. Studies which were published in English, studies with different years of publication were included. Studies which includes bond strength of MTA as endodontic sealer to dentinal wall were also included. Studies used in this review were invitro studies and clinical trials. Studies showing tissue toxicity, biocompatibility of MTA were excluded. Also, case reports and invivo studies were excluded. All abstracts as well as full texts were studied. PubMed/Medline, Web of Science, and Scopus were used for this study. Keywords used were “root canal sealer”, “pushout bond strength”, “MTA”. Total 18 articles were collected. But only five articles fulfilled the inclusion and exclusion criteria. So only five articles were included in this study and discussed in detail.
Results: According to the results of articles which were chosen for this study stated that MTA can be used as an endodontic sealer though it shows lesser pushout bond strength when compared with different newer sealers.
Conclusion: In this systematic review only one invitro study showed that Pro root MTA used as root canal sealer exhibits high pushout bond strength than other sealers like MTA Fillapex sealer and AH plus sealer. While MTA Fillapex show lesser pushout bond strength in comparison with other sealers like Pro root MTA sealer, AH plus, Endo CPM sealer. So this systematic review partially fulfills the hypothesis as it gives a utility of Pro root MTA as a root canal sealer.
