Therapy of deep caries by transverse excited atmosphere pressure carbon dioxide laser: an in-vitro investigation

摘要

Abstract: Deep carious decay is still a problem for conservative dentistry. A prototype of a transverse excited atmospheric pressure carbondioxide laser (TEA-CO$-2$/-Laser) was used for testing the properties in selective ablation of softened carious dentin, artificially sclerosing the remaining dentin, and providing thermal damage for the pulp. Using low pulse frequencies of 1 or 2 Hz, pulse durations of 50 ns, and pulse energies of 5 J/cm$+2$/ the TEA-CO$-2$/-Laser seems to be able to solve the therapeutic problem. !6
