Title: Effects of diode laser irradiation on dental pulps in rats
Author: C. Guler, H. Alan, P. Demir, N. Vardi

Abstract: OBJECTIVES: To evaluate the effects of different power densities of diode laser on dental pulps in rats.
BACKGROUND: In this study, we used the maxillary central incisors (n=80) of the 40 adult male Wistar albino rats.
METHODS: Rats were randomly divided into four groups according to power densities of diode laser (n=10). Histopathological changes in pulp and height of odontoblast layer were examined . All data were compared statistically using Mann‒Whitney U (Bonferroni) test, p<0.05.
RESULTS: G2 displayed slight histolopathologic alterations such as odontoblast cell disorganization and irregularities in cell extensions. Alterations were more prominent in the G3 than G2. Although the lowest odontoblast layer was measured in the G4, the difference in height of odontoblast layer among the groups was not found to be statistically significant.
CONCLUSION: It was concluded that the use of diode laser caused changes at the cellular level in histological examination and may induce the formation of tertiary dentin by influencing the secretory activity of odontoblasts. As long as used in accordance with the recommended procedure, the diode laser can be safely used in dental hard tissues (Tab. 1, Fig. 4, Ref. 15).
