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.
