Temperature rise in pulp horns of maxillary CT (group 1). Temperature rise after application of hot plate and grinding the occlusal surface, respectively. Arithmetic mean values as well as their standard deviations are displayed. The short line within the rectangle shows the median. The upper and lower limits of the rectangle correspond to the 25th and 75th percentiles, respectively. Minimum and maximum values are marked with a + -symbol. The mean values of the individual pulp positions are displayed: pulp position 1: n = 13, pulp position 2: n = 13, pulp position 3: n = 6, pulp position 4: n = 9, pulp position 5: n = 5. a) Heat application by means of hotplate: measurement of intra-pulp temperature increase by 5.5°C. b) Selective grinding of supra-pulp occlusal surfaces. c) Intra-pulp temperature increase after ending the grinding process. d) Intra-pulp cooling phase: measurement of timespan until reaching the base temperature of 22°C.
