9.An Experimental Study on Renal Tissue Damage of Rabbit According to Neodymium-YAG Laser Energy.
Korean Journal of Urology 1985;26(6):585-589
Neodymium YAG (Nd-YAG) laser is a new instrument for the treatment of various urologic disorders where coagulation is necessary but still limited in cases. It avoids many of the side effects of electrocoagulations. Nd.YAG Iaser is a safe and effective modality, reducing blood loss, shortening operation time and preserving functional integrity on remaining renal tissue. In this experiment, to investigate the Nd-YAG Laser effect to renal tissue and the adaptation to renal surgery were aimed. We made the experimental study on renal tissue damage according to the change of irradiation time and power of NJ-YAG laser. The following results were obtained; After irradiation of Nd-YAG laser, renal tissue damage was noted on 30 Watt, 3 seconds and 5O Watt, 1 second, and the degree of renal tissue damage was increased with in creasing of laser power and time. A 2mm depth injured renal tissue was noted on 150-250 Joules, which coagulates the vessel with several mm diameter. Judging from the results of this experiment it may be believed that Nd-YAG laser can be adaptable to renal surgery in bleeding control without severe renal tissue damage.

Submerged implants require secondary surgical uncovering of implants after healing period of 3 - 6 months. In surgical methods, there are surgical scalpel, tissue punch, electro-surgical, and laser-used uncovering, and laser-used uncovering, and so forth. The objectives of this study are investigation and assessment of 1) thermal change in clinical application for uncovering of HA-coated implant and pure titanium implant irradiated by pulsed Nd-YAG. CO2, and Er-YAG laser. 2) surface change of cover screws after irradiation using laser energy. The temperature of apex & side wall of implants were recorded at 10sec, 20sec, 30sec after 30sec irradiation to implant healing screw; 1) pulsed Nd-YAG laser; 2W, 20pps, contact mode 2) CO2 laser; water-infused & non-water infused state, 2.5-3.5W, contibuous mode, noncontact mode 3) CO2 laser; non-water-infused state, 3W, superpulse, noncontact mode 4) Er-YAG laser; (1) non-water infused state, 10pps, 60mj, contact mode (2) water-infused state, 10pps, 60mj, 80mj, 101mj, contact mode According to the results of this study, pulsed Nd-YAG laser is not indicated because of increase thermal change and pitting of metal surface of implant cover screw. By contrast, CO2 laser & Er-YAG laser are presumed to indicate because of narrow range of thermal change & near abscence of thermal damage of metal surface. Dental laser is thought to be much helpful to surgical procedure when it is used as optimal power and time condition considering characteristics and indications of each laser. Further research is needed to verify that these techniques are safe and beneficial to implant success.
