Popis: The purpose of this study was to evaluate performance in oral soft tissue surgery and the periodontal tissue interactions resulting from increasing the repetition rate of a pulsed-mode Er:YAG laser system from 10 to 30 pulses per second (pps). Five beagle dogs aged 2 or 3 years old were used in this study. The specific maneuvers were performed for a gingivectomy and the removal of melanin pigmentation. A trial Er:YAG laser, which is adjustable up to 30 pps of repeated rate, was used. As for gingivectomy, the output power was made under eight conditions (35 mJ–30 pps, 35 mJ–20 pps, 70 mJ–10 pps, 70 mJ–20 pps, with or without water). The irradiation condition for the removal of melanin pigment was set at 35 mJ–30 pps with or without water. The observation periods were immediately, 7 and 28 days. Specimens were made and observed under a light microscope. Procedures of the gingivectomy and removal of melanin pigmentation resulted in favorable healing, regardless of the irradiation conditions. Increasing the repetition rate up to the 30 pps with low power significantly improved the smoothness and morphology. The high-repetition-rate Er:YAG laser technology described is advantageous, compared with low-repetition-rate Er:YAG lasers, and is applicable in a variety of oral soft tissue surgical procedures.
