Frenectomy is a routine oral surgical procedure performed to excise an abnormal frenum attachment in order to enhance oral function and esthetics. Diode laser has become more popular than conventional scalpel methods, due to promises of decreased postoperative pain, less bleeding, and quicker healing.This review compares the effectiveness of diode laser-assisted frenectomy in relation to tissue healing, patient discomfort, and clinical outcomes in comparison to scalpel frenectomy. Pertinent randomized controlled trials (RCTs) and observational studies were examined.The results indicate that diode laser frenectomy is associated with less intraoperative bleeding and pain, and with similar long-term healing rates.
