title: A new approach to restoring root-end cavity preparation in surgical endodontic procedures--a scanning electron microscopy study.
abstract: While many different restorative materials are now available for filling root-end preparations in surgical endodontic therapy, each one has drawbacks. The current study suggests that a flowable composite resin, cured by a high-power curing light in 10 seconds, may be the material of choice. The significance of coating the resected root surface with a dentin-bonding agent is also discussed.
