“…They have shown increasing resistance to root fracture and a highly relevant success factor for the longevity of future restoration of endodontically treated teeth. 33,34 Post-space cleaning must be implemented regardless of the endodontic sealer used for canal obturation. 35 To ensure that the presence of the smear layer did not have positive or negative effects after post-space preparation, 17% EDTA and 5.25% NaOC1 irrigation solutions, respectively, were used to remove it.…”

“…This study was approved by the Research Ethics Committee of the Ribeirão Preto School of Dentistry, University of São Paulo (CAAE: 61010022.8.0000.5419). The sample calculation was made by using the SigmaPlot v.12.00 program (Systat Software, San Jose, CA) based on parameters from previous studies [31][32][33][34]. A probability level of α = 0.05 and a statistical power of 0.9 were considered, with an estimated minimum number of 10 specimens for each group for bond strength tests, failure pattern and analysis of the adhesive interface.…”

“…Endodontic treated teeth are often restored with intraradicular posts due to excessive loss of coronal structure caused by caries, previous restorations, or fractures [1][2][3] . The retention of fiberglass posts inside the root canal depends on their characteristics such as length, diameter, and type of surface (serrated cylindrical, smooth cylindrical, conical, and double conic), as well as the type of cementing material 1,4,5) , technique used to insert the cementing material into the root canal 5,6) , and integrity of the adhesive interface 3,[7][8][9][10][11][12] .…”

“…The literature has demonstrated the maladaptation at the adhesive interface between the post, resin cement and root dentin of restorations performed with fiberglass posts in endodontically treated teeth 3,[9][10][11]25,26) . This has been found especially in root canals with oval or flattened cross-section 10,11,25,26) since the lack of compatibility between the diameter of the root canal, and the fiberglass posts leads to the formation of a thicker film of resin cement around the posts 25,27) thus compromising their adaptation to the dentin walls and BS [26][27][28] .…”
