In our study, we used the scalpel Er:YAG laser 2940 nm and conventional surgery in the incisions wound in order to discover the advantage of using laser after oral soft tissue biopsy in terms of the haemostasis, duration of incision, local anesthetic and postoperative pain.
This study has been conducted in the Oral and Maxillofacial Surgery Department at Dentistry College /University of Bagdad and Oral and Maxillofacial Surgery Department in Al-Kindy Hospital between April 2017 and July 2017. Thirty patients have been enrolled and divided into two groups, each group consisted of fifteen patients. The first group requiring biopsy based on their indications for biopsy in the oral cavity, where the incision has been done using surgical blade No.17. The second group needed biopsy in the oral cavity based on their indications for biopsy, but here the incision has been made by using Er:YAG laser 2940 nm with the output power (5Watt) in Continuous wave operation in contact with the tip of bare fiber 250 micron. All the biopsies in the both groups were excisional and done under local anesthesia using infiltration technique.
