Sealing performance of a universal adhesive in the root canal: evaluation at six and twelve months

The primary purpose of a post is to retain the coronal restoration in an endodontically treated tooth that has suffered an extensive loss of crown structure. The success of posts depends of the quality of the bonding between the post, resin cement and root dentin. The adhesive system is a key factor in ensuring immediate and durable sealing and long-term retention. Our study is designed to evaluate the sealing of a canal with fiber post anchor after using universal adhesive system Prime&Bond active with the two strategies, total-etch-and-rinse or self-etch comparing with an etch-and-rinse adhesive, Prime&Bond XP. The non-destructive measurement of fluid flow through endodontically treated teeth with fiber posts was followed repeatedly during a one year aging period. The results show that the universal adhesive gives the same results regardless of its strategy of use and these results remain stable at 6 and 12 months.
