Discomfort Following Oral Biopsy Comparing Laser and Punch Biopsy

Oral biopsy is essential for diagnosing mucosal lesions such as oral lichen planus (OLP). Laser surgery offers a minimally invasive alternative to traditional techniques, but thermal effects may impact healing and postoperative comfort. The aim of this study was to compare the degree of clinical healing and postoperative discomfort between laser and punch scalpel biopsy techniques in patients with OLP. This was a single-center, parallel-group, noninferiority, randomized, blinded, controlled trial. One hundred and twelve adults with clinically and histologically confirmed OLP were randomized and allocated into two groups. Test group (diode laser) and control group (punch scalpel).
