This study was conducted to investigate the effect of the newly introduced intracanal medicament (propolis) on the fracture resistance of root dentin compared to Triple antibiotic paste and Chlorhexidine.MethodThe root canals of mandibular premolars (n = 180) were instrumented and randomized into four groups; Group Propolis (PRP), Triple antibiotic paste (TAP), Chlorhexidine (CHX) and Control group (CNT) according to the medicament used. Teeth were incubated in 100% humidity at 37 °C for 3 days, one week and one month. After each period, teeth were subjected to a fracture resistance test. Two-way ANOVA and Tukey's post hoc pairwise test were used for statistical analysis.ResultsNo significant difference was found between different groups after 3 days and one week There was a significant decrease (P < 0.0001) in fracture resistance after one month for both TAP and PRP while the decrease was not significant for CHX and the control group.ConclusionUnder the conditions of this study, Propolis and TAP when used as intracanal medicaments adversely affects fracture resistance of root canal dentin, CHX is safe as an intracanal medication regarding the fracture resistance of root canal dentin
