Abstract
Introduction: This study was done to evaluate the effect of different intracanal medicaments on root canal dentine microhardness.
Method: Three intracanal medicaments were used in this study: Propolis , Calcium hydroxide and Chlorhexidine to evaluate their effects on microhardness of dentine in single rooted , human anterior teeth with a single canal. The medicaments were placed for three, seven and twenty one days. Samples were divided into three groups according to the intracanal medicaments used. Vickers microhardness tester was used to measure the surface hardness of the dentin of all specimens.
Results: The comparison of microhardness between the three intracanal medicaments on root canal dentin over the study period showed statistical significant difference (p < 0.001) in all groups where chlorhexidine showed the highest mean values, followed by propolis and finally calcium hydroxide group. The largest decrease was demonstrated between day 7 and day 21 time period.
Conclusions: All the three internal medicaments decrease dentin microhardness in endodontically treated-teeth by time.
