Dye leakage study: comparing conventional and new techniques.
Abstract
The purpose of this study was to compare the degree of dye penetration of Thermofil and Simplifill to standard lateral condensation using AH26 plus. Forty-five human maxillary incisors were instrumented and obturated with three different methods: Rotary Profile with the Thermofil method and AH-26 Plus sealer, Rotary Lightspeed with the Simplifill method and AH-26 Plus sealer, and hand file with lateral condensation and AH-26 Plus. An additional 45 teeth were used as positive controls in three separate but corresponding groups, and another 15 were in negative control group. Apical leakage was measured and evaluated on both the internal canal surfaces and the obturation material itself. The results showed that there was a significant difference between the control and obturated groups but no significant difference between any obturation groups.
