An In-Vitro Study Comparing the Effects of Three Different Intracanal Medications on Push-Out Bond Strength into the Dentinal Tubules of Root Canal

This study compared and assessed the adaptability of a premixed bioceramic sealer and the formation of a physical barrier between the filling material and the dentinal tubule penetration.Bio-C Sealer (Angelus, Londrina, Brazil), a Bioceramic Endodontic Sealer with the combination of MTA (Meta BioMed) Ceraseal and Cold fowable, polydimethylsiloxane based root canal sealer with nano silver (Prevest Denpro) Nanoseal-S.Materials and Methods: 45 wide roots, with single straight canals and formed apices, were endodontically prepared and divided into three groups (n = 15) according to the sealer used for the root canal lling: Group 1: Bio-C Sealer Group 2: Ceraseal MTA Group 3: Nanoseal-S.As controls, three samples were kept.After the canals were led, the samples were sliced and imaged under Scanning Electron Microscopy to analyse tubular penetration and sealer adaption.The Shapiro-Wilk, Levene, and Mann-Whitney tests were used to analyse the data (P0.05).Furthermore, in all three-thirds of the cases studied, Bio-C Sealer demonstrated better tubule penetration than Nanoseal-s and Ceraseal.
