Abstract

Different approaches for painless, fast and localized laser treatment of dental hard tissue is a subject of continuing research for the scientists. Studies of dentine ablation with Er:YAG and Ho:YAG lasers have indicated several weaknesses of the surface preparation process expressed in melting, Assuring and slow material removal rates. Some modifications of these systems (Er, Cr:YSGG) were introduced in dental practice in combination with water spray in order to enhance the surface preparation by cooling the ablated region and increasing the ablation rate [1]. Applications of Ti-sapphire laser pulses with durations <50fs for ablation of dental tissue, followed by examination with ESEM and AFM are seldom reported in the literature [2].
