The effect of the dental tip length on the bactericidal effect of NCP mounted with dental tips. (A) The capillary tips (originally 4.5 cm in length) were cut into 1.5, 2, 2.5 and 3.5 cm, and mounted on NCP device. S. mutans inoculated on solid medium was treated with the NCP for 1, 3, 5 min. At 24 h after the treatment, the photographs showing a clear zone were taken, and the size of a clear zone was measured. (B) The microcapillary tips (originally 4 cm in length) were cut into 3 and 3.5 cm, and mounted on NCP device. The S.mutans on solid medium was subjected to NCP treatment for 1, 3 and 5 min. At 24 h after the treatment, the photographs showing a clear zone were taken, and the size of a clear zone was measured.
