12 Months Results of Bond Strength and Endogenous Enzymatic Activity of Radicular Dentin Obturated With Bioceramic Sealer.

The results showed that bioceramic sealers should guarantee better results in radicular dentin bond strength, without altering the endogenous enzymatic activity. The heat produced during the root canal obturation might reduce the internal enzymatic activity but, in association with bioceramic sealers, after 12 months, it produces higher bond strength. Heat reduces the difference between the two adhesive systems. ER technique and aging increase enzymatic activity. Aging tends to increase bond strength, especially in traditional sealers groups associated with ER protocol.
