Abstract:
When the root canal is filled, the use of the adhesive resin-based sealant to form a strong bond with the dentin reduces microleakage of the apex, enhances the bending resistance of the tooth, and resists the mechanical damage of the pile preparation, thus improving the success rate of root canal treatment. However, during root canal treatment, the use of a rinsing agent may change the tissue structure of the dentin and the wettability of the dentin, thereby affecting the bonding strength between the resin sealing agent and the dentin. In this paper, the effects of a traditional root canal irrigant and several new rinsing agents on the bonding strength of resin sealant and dentin are reviewed. The results show that the traditional root canal rinsing agent NaClO is reduced as the final rinsing agent. The bonding strength of resin sealant to dentin; EDTA affects the biomechanical properties of root dentin, and the removal efficiency is low, which will affect the bond strength between the resin sealant and dentin. EDTA combined with NaClO as a final rinsing agent can improve the bonding strength. Chlorhexidine can also increase the bonding strength between the blocking agent and dentin and can be used as the final rinsing agent. The new rinsing agent MTAD has a negative impact on the resin sealing agent and dentin bond strength. QMix and maleic acid remove smear efficiency with dentin bond strengths greater than or equal to EDTA and can replace EDTA as the final rinse.
