Effects of calcium hydroxide and propolis intracanal medicaments on bond strength of resin-based endodontic sealer as assessed by push-out test.
The aim of this study was to investigate the effects of calcium hydroxide (Ca(OH)2) and propolis intracanal medicaments on bond strength of AH Plus to root dentin. After chemomechanical instrumentation using Revo-S rotary system, three groups of root canal specimens were prepared: 10 root canals were left untreated as controls (G1), 10 received Ca(OH)2 intracanal medicament (G2), and another 10 received propolis intracanal medicament (G3). Canals were obturated with AH Plus and gutta-percha. After bond strength evaluation using micro push-out test, data were analyzed using ANOVA and Tamhane's test (p=0.05). At coronal and middle thirds, there were no significant differences in bond strength among the three groups (p>0.05). At apical third, G3 was significantly superior to G2 (p<0.05) and G1 (p<0.05), but there was no significant difference between G2 and G1 (p>0.05). Therefore, when AH Plus was used as the sealer in endodontic treatments, its combined use with propolis as an intracanal medicament seemed to result in favorable sealer-dentin interfacial bond strength.
