Abstract

BÖKEN KIR E. The Effect of Triton, a Novel Irrigation Solution, on the Push-Out Bond Strength of Epoxy Resin-Based and Calcium Silicate-Based Root Canal Sealers. Hacettepe University Faculty of Dentistry, Department of Endodontics, Specialization Thesis, Ankara, 2026. This study evaluated the effect of Triton, a novel irrigation solution, on the push-out bond strength of epoxy resin-based and calcium silicate-based root canal sealers. A total of 90 extracted human single-rooted teeth were used in the study. Specimens were divided into two main groups based on the final irrigation protocol: Triton and conventional irrigation (n=45). Each main group was further subdivided into three subgroups based on the root canal sealer used: AH Plus (Dentsply, USA), MTA Fillapex (Angelus, Brazil), and CeraSeal (Meta Biomed, South Korea) (n=15). Root canals were prepared to size F4 using the ProTaper Gold rotary file system (Dentsply Maillefer, Switzerland). The corresponding irrigation protocols were applied, and the final irrigation solutions were activated with an EndoActivator (Woodpecker-Dte, China). After obturation with the assigned root canal sealers, coronal and middle root sections were obtained from each specimen. Push-out bond strength testing was performed on a universal testing machine (Lloyd LRX, England), and failure modes were evaluated under a stereomicroscope (Olympus, SZ-61, Japan). Data were analyzed using appropriate statistical methods. No statistically significant differences were observed between the Triton and conventional irrigation protocols in the coronal and middle sections of the AH Plus, MTA Fillapex, and CeraSeal groups (p>0.05). A statistically significant difference among root canal sealers was observed only in the coronal section of the conventional irrigation group (p=0.003), attributable to the comparison between the AH Plus and MTA Fillapex groups. MTA Fillapex exhibited lower bond strength values. A significant difference between the coronal and middle sections was observed only in the MTA Fillapex subgroup of the conventional irrigation group (p=0.047). Cohesive failure was the primary failure mode across all groups. Within the limitations of this study, the Triton irrigation solution performed comparably to the conventional irrigation protocol in terms of the push-out bond strength of root canal sealers. In addition, AH Plus and CeraSeal tended to exhibit higher bond strength values than MTA Fillapex, and cohesive failure was the predominant failure mode in all groups.
