Clinical and Microbiological Evaluation of Laser Assisted New Attachment Procedure (LANAP) Using Nd:Yag vs. Diode Laser in the Management Of Stage II Periodontitis

A free running, pulsed, 1064 nm wavelength-specific ND:YAG laser will be used. A thin 300 μm laser fiber optic will be placed parallel to the root surface, allows easy access into deep periodontal pockets. The initial pass with the laser is known as Laser Troughing, and it is done with a micro-short duration pulse, with a 4.0 watt power, 150 μs duration in pulsed mode and 20Hz frequency. Ultrasonic scaler will be then used to remove calculus. The second pass is carried out with 650 μs pulse duration, 10-30 seconds for each tooth, 4.0 watt power and 20HZ frequency, to improve the ability to generate a fibrin clot. The fibrin clot is then compressed. Relieving the occlusion is the last step of the LANAP protocol.

"Diode laser (Biolase) with 940 nm wavelength, a thin flexible fiber-optic cable 300 μm attached with a power average set at 0.5-1.5 watt will be used.~The first pass laser troughing is done using a thin flexible fiber-optic cable 300 μm placed parallel to the root surface, attached with a power average set at 0.5-1 watt, in continuous mode. Ultrasonic scaler will be then used to remove calculus which present on the root surface. The second pass is carried out with 1-1.5 watt power in continuous mode, 10-30 seconds for each tooth, and, to improve the ability to generate a fibrin clot. The fibrin clot is then compressed in order to enhance the healing"

Scaling and root planing (SRP) using ultrasonic device at a moderate setting and with the appropriate tips and curettes will be also used where indicated and time spent in SRP on each tooth will not be restricted.
