Analysis of adhesive interface in root canals irradiated by Er,Cr:YSGG laser after luting a fiber post.

This study evaluated the effect of Er,Cr:YSGG laser on the root canal dentin after luting a fiber post. Twenty-four bovine teeth roots were prepared using NiTi instruments and filled with Sealer 26 and gutta-percha. Post spaces were prepared and roots were distributed according to dentin treatment (n = 8): 2.
