Artificial Caries Resistance in Enamel after Topical Fluoride Treatment and 445 nm Laser Irradiation

Figure 6

Mean real time temperature increment in the roof of the pulp chamber during the 445 nm laser irradiation (0.3 W 60 s and a dose of 90 J/cm²). The shaded area represents the time of laser irradiation on the occlusal surface. The peak temperature shown in this graph is lower than the mean of the maximums of 2.12°C; this is due to that the samples reach their maximum intrapulpal temperature at different times leading to a lower-averaged curve.
