ABSTRACT
Fifty-six teeth were initially instrumented, with the use of seven irrigants or irrigant combinations, and filled with radioactive albumin. The study then showed the relative ability of three final endodontic procedures (copious reirrigation with saline solution, drying with paper points, and reassuring patency of the canal with the final instrument) to remove the albumin. Even after copious irrigation, each additional procedure removed statistically significant amounts of albumin. Alternating an organic solvent and an inorganic solvent did appear to leave the canal system in the optimal condition for final cleansing procedures. The study then correlated the relative efficiency of irrigation alone versus instrumentation plus irrigation in removing the remaining albumin from the canal systems. Reinstrumentation plus copious irrigation removed significantly more albumin than copious irrigation alone.

Two case reports are presented to illustrate the effectiveness of cold in localizing the offending tooth in difficult diagnostic situations where painful pulpitis is present. A review of the literature reveals that there are several proposed theories concerning the mechanisms by which cold relieves the painful symptoms present in some cases of irreversible pulpitis. The hydrodynamic theory seems to provide the most feasible explanation of the events that occur.

A case report illustrates an esthetic temporary restorative technique for use during the stabilization period after vertical root extrusion. A polycarbonate crown was adapted to the stabilized root and anchor system with acid-etch composite resin material. This restoration withstood a five-month stabilization period and provided both function and a good esthetic appearance.
