| Abstract | ||||
| Aim: The aim of this study was to evaluate the effect of two concentrations of quercetin irrigant (2% and 6.5%) and 2% chlorhexidine (CHX) irrigant on root canal dentin microhardness. Materials and methods: The study was done on thirty human extracted teeth. Their crowns were removed at the cementoenamel junction (CEJ). They were categorized randomly into three groups in accordance with the type of irrigant used. Each group contained ten teeth. Group A: 2% quercetin irrigant. Group B: 6.5% quercetin irrigant. Group C: 2% CHX irrigant. The roots were sectioned in a longitudinal direction by a chisel into two halves. Each half was dipped in an acrylic resin. One half was used as a control to measure the microhardness without irrigation, and the other half of the same root was used as an experimental half to measure the microhardness after the application of irrigants for fifteen minutes. Microhardness was measured by a Vickers tester. Results: 6.5% quercetin irrigant (group B) was significantly the highest mean value of microhardness, followed by 2% quercetin irrigant (group A), while 2% CHX irrigant (group C) was significantly the lowest mean value of microhardness in all sections and overall. Conclusion: The microhardness of root canal dentin was increased after irrigation with 6.5% quercetin irrigant and also after irrigation with 2% quercetin irrigant, but to a lesser extent, whereas it was decreased after irrigation with 2% CHX irrigant. | ||||
