Comparative evaluation of effect of chloroquick irrigating solution on push-out bond strength of endoseal mineral trioxide aggregate and endosequence root repair material when used as furcal perforation repair material: An in vitro study

AIM: The purpose of this study was to comparatively evaluate the effect of Chloroquick irrigating solution on push-out bond strength of Endoseal mineral trioxide aggregate (MTA) and endosequence root repair material (ERRM) when used as furcal perforation repair materials. MATERIALS AND METHODS: Forty human extracted mandibular molars were collected. A standardized endodontic access cavity was prepared in 40 samples, and intentional perforation of 1.32 mm in diameter was created on the pulpal floor. Teeth were randomly divided into four groups: Group A: EndoSeal MTA with irrigation, Group B: ERRM with irrigation, Group C: EndoSeal MTA without irrigation (Control group), and Group D: ERRM without irrigation (Control group). The samples were subjected to universal testing machine then examined under a stereomicroscope at × 40 to determine the nature of the bond failures. RESULTS: EndoSeal MTA with Chloroquick irrigating solution irrigation showed the highest push-out bond strength (MPa) with a statistically significant difference among all the groups (P = 0.003). The majority of the samples exhibited cohesive and mixed types of failures. CONCLUSION: Chloroquick irrigating solution irrigation has no adverse effect on the push-out dentin bond strength of Endoseal MTA and ERRM.
