Pulp temperatures after cold stimulation of normal and endodontic-treated teeth. A thermocouple probe was placed through the apical foramen into the pulp chamber of untreated and endodontic-treated teeth. (A) A cotton pellet saturated with EndoIce was applied to occlusal surfaces for 5 or 15 s, and changes in temperature were recorded. (n = 6/group). Data are presented as mean ± std dev of recorded temperature. **p < 0.01 and ***p < 0.001; One-Way ANOVA with Tukey’s post hoc test (B) Placement of the thermocouple probe in the pulp chamber was confirmed radiographically prior to cold stimulation.
