Influence of irrigation and laser assisted root canal disinfection protocols on dislocation resistance of a bioceramic sealer
Background: It is not yet clear how different irrigation protocols and intracanal laser irradiation affects bioceramic sealers. In this vitro study, we aimed to evaluate the dislocation resistance of a bioceramic root canal sealer after different laser-assisted disinfection protocols and irrigants. Methods: Sixty extracted human straight single- canal teeth were instrumented, and randomly divided into five experimental groups (n=10) according to the disinfection protocol used: group 1, conventional needle irrigation (CI) with sodium hypochlorite (NaOCl)+ethylenediaminotetraacetic acid (EDTA)+NaOCl ; group 2, Photon initiated photoacoustic streaming (PIPS) of NaOCl+EDTA+NaOCl ; group 3, NaOCl+EDTA+diode laser ; group 4, NaOCl+EDTA+photodynamic therapy (PDT) ; group 5, CI with NaOCl+EDTA+Chlorhexidine (CHX) ; and control group without any treatment. The root canals were filled with a bioceramic root canal sealer (BioRoot RCS) using the single-cone filling technique. After three weeks of storage, the samples from each canal thirds were transversely sectioned and the push-out test was performed. Results: The PIPS group showed the lowest dislocation resistance values in the coronal third (p>0.05), and no difference was observed among the other groups (p<0.05). The dislocation resistance in the middle and apical thirds was the highest in the diode laser group (p<0.05). Conclusion: Final root canal irradiation with diode laser led to improved dislocation resistance of the bioceramic sealer. PDT did not adversely affect the dislocation resistance of BioRoot RCS. The PIPS reduced the dislocation resistance values in the coronal third, but not in the middle and apical thirds.
