Evaluation of a New Thermoplastic Gutta Percha Obturation Technique Using 45Ca.

Abstract

This study evaluated the leakage following in vitro gutta percha obturation of 60 root canals using 3 techniques, both with and without use of sealer. The techniques were: lateral condensation; warm (vertical) condensation; and the new mechanical compaction (McSpadden) technique. Comparison of the techniques were made by evaluating horizontal sections of the teeth by radioautography after soaking the teeth in 45Ca. The difference between techniques was not statistically significant. Additionally, at only one level (1.4mm) in only one technique (compaction) did sealer show an improvement in seal at a statistical level of even p < 0.085. Since this cannot be considered statistically significant, factors which may have lead to the results are discussed. (Author)
