ABSTRACT
Aim:
Background: Laser is an advantageous system that can be used in different medical applications, and one of them is hard tissue handling in operative, periodontal, and maxillofacial. Aims: This study aimed to compare the efficiency of Er, Cr: YSGG laser, and handpiece bur in bone cutting by histological examination.
Material and methods:
Materials and methods: This was an ex vivo study using the bone specimens from the sheep as samples, different ER, CR: YSGG laser parameters will be used (2.5W, 20Hz/4W, 20Hz/6W, 20Hz) versus slow hand piece to make osteotomy. After histopathological processing, the length, width, length-to-width ratio, precision, and carbonization of laser osteotomy will be examined under a light microscope
Results:
Results: ER, CR: YSGG lasers can be considered practical, effective, and easy for bon incisions. The histological results showed high incision quality with the Er, Cr: YSGG laser system, versus slow speed handpiece. The quality of laser incision at 4W, 20HZ is the best among the parameters p<0.001.
Conclusions:
Conclusion: The Er, CR: YSGG laser if used properly with appropriate parameters is very effective alternative device in oral osteotomy.
