Abstract

The aim of this study was to assess leakage of root canals obturated using different techniques: cold lateral condensation, warm lateral condensation (Touch’n Heat) and Thermafil. The experimental sample had 70 single rooted permanent teeth. Root canals were instrumented using step-back technique. The teeth were randomly assigned to three groups of 20 samples and obturated using experimental techniques. Ten samples were used as control samples. After a fifteen-day setting period in sterile saline, the samples were taken out, dried, covered by insulating varnish and placed in test-tube with dye. After seven days, the samples were subjected to demineralisation in nitrogen acid, dehidration in ethanol and submerged in methyl-silicilate, thus rendering them transparent. Dye penetration was then read using stereomicroscope. The results were processed by two-way analysis of variance with LSD post hoc test. The results indicate significantly lower dye-penetration in samples obturated using Touch’n Heat technique (0.63±0.35mm) and Thermafil (0.71±0.57mm), when compared to the sample obturated using cold lateral condensation (1.31 ±0.75mm).
