Abstract

The objective of the current study is the comparative assessment of physico-chemical properties of two bioceramic-based root canal filling materials (the conventional TotalFill BC sealer and an experimental sealer (ICCRR Cluj-Napoca)) using different storage media. Forty monoradicular teeth were included in the study. The root canals were mechanical and antiseptically treated (using photodynamic therapy or classic irrigants), obturated using one of the two sealers and then stored in different media (saliva or bovine blood). Samples were embedded in resin, sectioned and analyzed using Fourier Infrared Transmission Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM). The interaction between TotalFill and saliva was weaker, while the experimental bioceramic sealer had a similar behavior in the two storage media, however, the interaction with saliva was stronger than the interaction with blood for the experimental sealer, but the results were not significant. Storage media can influence sealer adhesion to root dentin. Photodynamic therapy improves the adhesion of the root canal filling material..
