ABSTRACT
The accuracy with which root canal space is sealed is a major determinant in the Endodontic success. Use of pressure-syringe to introduce root canal sealer in the root canal without gutta percha or silver cone represents a modification to current technique of obturation. This study investigates the sealing capabilities and adhesiveness of various root canal sealers with the use of pressure syringe technique. Apart from eliminating the use of solid core, pressure syringe technique can be used as a new obturation method since it showed better marginal sealability than the conventional technique.

In the present study, four restorative materials were used for the restoration of endodontically treated anterior teeth and their strength were compared with that of natural teeth. 100 freshly extracted Maxillary Central Incisors were used. The teeth were restored with Pin-retained amalgam-core buildups, Dowel-post with Glass ionomer-Amalgam alloy combination Cast Core build up. The natural tooth showed the maximum strength. Though some of the restorative materials showed promising results, none of them is able to show strength anywhere near to that of natural tooth.

Dental hypersensitivity is a very distinct and annoying clinical complaint. The treatment of dentinal hypersensitivity can be a serious problem in professional dental practice. Many studies have been undertaken and corresponding treatments suggested resulting in various degrees of relief for the patient who is afflicted and concerned that his pain will be further provoked by eating solid or liquid food or by drinking cold or hot beverages. This concern also may cause psychic tension which can reduce the threshold of tolerance to all external stimuli to lower than normal levels.
