Effect of CO2 laser irradiation on experimental fracture healing: a transmission electron microscopic study.

abstract：BACKGROUND AND OBJECTIVES:Nitrogen laser-induced fluorescence (LIF) spectra of sound tooth consists of two broad bands centered at 440 and 490 nm, with two apparent side bands on either side. In order to locate the exact peak position of these bands and to effectively utilize the LIF spectral signatures for detection o...
