Recently, the range of treatment parameters of Variable Square Pulse (VSP) Er:YAG lasers has been significantly extended. With the latest Quantum Square Pulse (QSP) technology, minimally invasive treatments that require extremely high finesse are now possible. In addition, a new digitally controlled dental laser handpiece has been developed to help guide the laser light swiftly and accurately across the surface of treated tissues, thus allowing the practitioner to perform treatments involving otherwise unattainable patterns.
In this study, a digitally controlled dental laser handpiece was utilized to measure the ablation efficacy of the Er:YAG laser’s QSP mode. The QSP mode was found to have a considerably higher ablation efficacy (by a factor of 1.4) when compared to the standard “single” (non-quantized) Er:YAG laser pulses.
