Abstract

Many ways and techniques were used for subgingival calculus removal to be achieved, from scaling and root planning closed and opened technique, manual curettes, air abrasives, and finally dental lasers machines. Material and methods In this study, we will compare conventional ultra-sonic scaling and curettes to two laser groups using Er,Cr:YSGG 2780 nm. One group (LASER) using 25 mJ, 50 Hz, 50 μs pulse duration, 20 ms pulse period, 1.25 W average power, 500 W peak power W/A:80%/10%, and other group (LASER+) using manufacturer instructions: 47 mJ, 75 Hz, 50 μs pulse duration, 3.5 W average power, 940 W peak power, W/A 40%, 20%. Fifteen extracted teeth that have subgingival calculus was usedineachgroup. Results Showed no statistical difference between time in three groups, there was a statistical difference concerning the amount of calculus, group laser + showed least amount of calculus remaining. Root roughness showed statistical significant, the laser + treatment shows significant higher root values than the laser treatment as well as compared to conventional treatment. Laser scanning showed no statistical difference concerning root roughness. SEM showed con- ventional group with roughness and smear layer, laser group showed the most smooth surface, laser + showed the most rough
