Comparison of four thermocycling techniques.
This investigation revealed no significant difference among the four thermocycling techniques. The use of a dye or an isotope was equally effective and penetrated the tooth/restoration interface to a similar degree. The extent of tracer penetration appeared to be independent of the dwell time in the thermal baths. All procedures involving thermal changes were more potent in demonstrating leakage than the noncycled method.
