A histopathological study was performed on the tooth pulp of mongrel dogs after cavity preparation using the conventional high speed method (control group) and the newly developed Er:YAG laser system (laser group, output energy: 100 mJ, 150 mJ, and 200 mJ/pulse). All samples were divided into two groups (deep cavity and shallow cavity) according to the remaining dentin thickness (RDT) and histopathologically evaluated. After 1, 2, 4, 7 and 28 days postoperatively, there was no histopathological difference between the control group and the laser group. Er:YAG laser irradiation with three different output energies made little difference in the degree of pulpal damage. In the deep cavities, damage of the pulp was more remarkable than the shallow cavities in all groups. The efficacy of cutting rate in the laser group was not very different from the control group.
