Abstract
Predictable endodontic success has increased sharply due to the formulation and practice of three basic principles of endodontic treatment. First is the proper diagnosis of pulpo-periradicular disease and forming a treatment plan determining the need for endodontic therapy. Second is the biomechanics or instrumention of the root canal space during which thorough debridement and preparation to receive a filling material is accomplished. The third is the obturation of the canal to produce an hermetic seal impervious to tissue fluids and bacteria. Fulfillment of these three basic principles offers a high degree of success, although some cases still fail. There have been many explanations to try to account for these failures. Two of the most accepted reasons are lack of an hermetic seal and incomplete debridement of the root canal system. These lead to continued pulpoperiradicular pathology. If, after all possible non-surgical root canal therapy fails, and further sealing of the root canal is required, then surgical access to the apical for amen is required. Even after all conventional and surgical root canal therapy, failures still exist as evidenced by continuing pulpoperiradicular disease. These failures are attributed to the inability of the reverse filling material to properly seal the apical constriction (preparation). A variety of materials and evaluation methodologies has been used with no one material producing an impervious seal in every situation. Continued study of retrofill materials and evaluation methods is necessary in quest of the "perfect" seal. This study has evaluated the sealing ability of zinc-free amalgam, Diaket, glass ionomer cement with silver particles and glass ionomer cement with resin using the electrochemical analysis of apical leakage.
