Soft tissue diode lasers are becoming popular among clinicians due to their potential value in surgical procedures providing, surface sterilization, dry surgical field, and increased patient acceptance. Twenty-five patients with different soft tissue lesions were selected, and soft tissue diode laser was used for excision and wound healing was assessed by the visual method with photographs. No discomfort to the patient during and after the laser procedure was observed. In spite of using minimal local anesthesia, avoiding placement of sutures, and not prescribing any antibiotics, minimal bleeding, no edema, and good wound healing were observed. We conclude that laser treatments can be superior to conventional approaches with regard to easy ablation, decontamination, and hemostasis and are less painful during and after the procedure.

Lasers have been used in oral and maxillofacial surgery for decades. The first documented use of lasers in oral and maxillofacial surgery was published in 1977.[1],[2] The reason for this transition is due to the fact that many procedures can be executed more efficiently and with less morbidity using lasers when compared with a scalpel, electrocautery, or high frequency devices. Early lasers were bulky and historically used for major cases in operating theaters; but today, access to small, portable, office-based lasers with improved intraoral delivery systems have made it possible to treat even minor routine procedures in the clinic.[3],[4],[5],[6],[7],[8],[9],[10],[11],[12] The aim of this case report was to present the clinical effects of diode laser irradiation on oral soft tissues during oral surgery and to demonstrate wound-healing characteristics after laser surgery.

 Case Report

Twenty-five patients with different oral surgical indications are included in this report. All of the patients were indicated for oral surgical procedure with the diode laser. The maximum output power was up to 15 W yet operated up to 9 W and had a continuous as well as a pulsed mode. Soft tissue surgery was carried out with different power settings, continuous or pulsed mode, and the use of a contact (focussed) or non-contact (defocussed) hand piece. The surgical procedures were performed under topical or local anesthesia [Table 1]. All of the clinical cases were examined in the first 3 days, 1 week, 2 weeks, and 3–4 weeks after surgery. Post-operative complications such as pain, bleeding, swelling, sensory disturbances, and functional and/or mobility disorders, as well as wound-healing characteristics, were evaluated. Only two cases experienced mild hot feeling sensation, and swelling was absent in all cases except one patient who underwent vestibuloplasty and even developed mild paresthesia but that recovered within 2 months of surgery. All other cases healed uneventfully with minimal requirements of analgesics (predominantly with potent anti-inflammatory action than analgesics like ibuprofen 200–400 mg), while antibiotic dependency was also markedly reduced (except in the tongue right lateral border incisional biopsy case which later confirmed to be a neoplasm) because of the local sterile environment. Laser bandages of the surgical sites were attained in all the cases. The same is clearly visible in the pre-, intra-, immediate, and delayed post-operative pictures of the patients which are as follows [Figure 1] and [Figure 2].{Table 1} {Figure 1} {Figure 2}


One of the applications of lasers in dentistry is soft tissue surgery and ablation of lesions. The excision of exophytic lesions is one of these applications. The advantages of laser application are relatively bloodless surgery, minimal swelling, scarring and coagulation, no need for suturing, reduction in surgical time, and less or no post-surgical pain. Furthermore, the laser instantly disinfects the surgical wound and there is no mechanical trauma to the tissue.[1],[2],[3],[4] The unique specialties of diode lasers, such as sharp and definite cutting edge, hemostasis, and coagulation after surgery in addition to small size and better maneuverability during application, make them very effective and a useful alternative device in soft tissue surgery in the oral cavity in comparison to other laser types such as carbon dioxide laser (CO2) and erbium lasers. In all the cases, a definitive excision of the lesion was accomplished and good healing was observed. During the procedure, the patients did not experience any discomfort or pain and no post-operative pain was observed. Minimal bleeding during the procedure was observed. Minimal local or topical anesthesia was needed during the procedure, and there was no need for suturing the surgical wound. Post-operatively, there was no edema and good healing was observed after 1 month of the procedure. Laser-induced wounds because of a definite and clean wound generally heal with secondary intention and no scar formation. This is may be due to the minimal degree of wound contraction following laser irradiation, which occurs through induction and formation of a smaller number of myofibroblasts and collagen. All parameters of lasers are selected based on thorough knowledge of laser applications in medical and dentistry involving basis principles of laser physics, laser chemistry, and laser–tissue interactions, such as selection of wavelength power irradiance must be based on the presence of substrate specific chromophores. Also one should keep in mind always that intra-operative conditions give equal emphasis on post-operative healing events, which can easily be attained by carefully performing selective photothermolysis, where ever intended.[5],[6],[7],[8],[9],[10],[11],[12] All of these will ultimately result in faster, uneventful, and least medication-dependent wound healing with predictable final outcome, when compared with conventional-primitive scalpel or electrocautery or RF systems, which falsely proclaimed similar results at the same time and comfort.


The application of diode lasers has been recognized as an adjunctive or alternative approach in soft tissue surgeries. Laser treatments have been shown to be superior to conventional mechanical approaches with regard to easy ablation, decontamination, and hemostasis, as well as less surgical and post-operative pain in soft tissue lesion management.
