“…The photocoagulation technique is very effective and safe for the patient. The high-intensity laser treatment can be done using the diode or Nd:YAG, which are very appropriate for treating small or extensive lesions, but technical knowledge is very important, and the laser device should be used by an experienced trained professional [ 13 - 15 ]. In cases where the lesion is larger, they might require more than one laser application session [ 16 ].…”

Small vascular anomalies are commonly present on the lips and other areas of the oral mucosa. These lesions are also known as venous lake lesions, and they can be treated in many ways with surgical and non-surgical methods. Laser is an arising technique for this type of procedure and its use has been growing in dental practices in the last years. The technique that uses the diode laser delivers the energy in a non-contact treatment, leading to the coagulation of the lesion in a minimally invasive manner, and for this reason, there is less chance of developing scar formation. In this report, a 56-year-old female patient had a vascular lesion on her lower lip measuring about 3.0 mm in diameter. The patient reported having it for more than 10 years. A first approach using a high-power diode laser had already been done but with no success. At this time, the diode laser was used under local anesthesia, with a flexible quartz fiber held 2 to 3 mm from the lesion, using the continuous wave mode set, 1.0 W of power for 10 seconds, with an interval of 30 seconds to prevent heat damage to the adjacent tissue. The laser was applied until the lesion appeared white and with evidence of shrinkage. In this case, two rounds of irradiation were done. After a 30-day follow-up, the lesion was repaired with no signs of scars on the lip. The diode laser is an effective technique for treating this type of lesion, with many advantages, such as providing coagulation, excellent healing, no postoperative complication, and no need for suturing. Besides all, it is also a low-cost procedure, small lesions usually require only one appointment, and this treatment is also better accepted by the patients.

“…The majority of soft-tissue procedures performed with diode lasers have output power between 2.5 and 1.5 W, continuous wave, with fiber activation, and these parameters create adequate power to cut tissue, with the fiber always placed directly on the tissue surface (contact mode) [ 8 ]. On the other hand, the usage of pulsed mode in diode lasers is possible, even though they can lead to gingival fenestrations and bone exposure, caused by the lack of control over temperature rise in gingival tissue [ 9 , 10 ].…”

“…The lack of fiber tip activation also plays an important role, allowing direct energy-pigment interaction. This is achievable due to near-infrared wavelength and its affinity for melanin and other pigments, which leads to pigment removal without major damage to surrounding tissues [ 3 , 10 ].…”

This case report describes the efficacy and advantages of using a high-power diode laser in non-contact mode to remove racial melanin pigmentation from the oral mucosa in an aesthetically sensible area to reduce thermal damage and promote better postoperative results. In the presented case, the lesion was removed under local anesthesia in a single session using high-power diode equipment with circular movements over the lesion (10 seconds maximum for each irradiation cycle, with 30 seconds for thermal relaxation, for a total of two cycles), maintaining an average distance of 2-3 mm from the target tissue without fiber activation (continuous wave, 2 W, delivered by quartz fiber with 300 µ). The patient did not report immediate postoperative pain; however, analgesic use was recorded during the first day after the surgical procedure. The biological response and cosmetic results were satisfactory, with proper lesion removal and adequate cicatrization observed during a two-year follow-up period, without complications or compromise of periodontal tissue esthetics.

“…The treatment of this type of lesions is often required only for aesthetic reasons because are asymptomatic, especially if smaller than 1 cm and with a little risk of traumatization. Among the treatments proposed in the scientific literature, there are sclerotherapy or injections with sodium tetradecyl sulfate [10,11], cryotherapy with liquid nitrogen [12], photocoagulation therapy with neodymium laser (1064 nm) and a high-intensity diode laser [13][14][15].…”

The classification of vascular lesions of the oral cavity is complex. To simplify, these lesions can be divided into two large groups: neoplasms (mostly benign) and vascular malformations. Laser treatment of oral vascular lesions seems to be an excellent device, and different wavelengths have been reported in the literature. The purpose of this work is to document a case of vascular lesion of the lip, developed in a few weeks in an adult patient successfully treated with a minimally invasive technique with the use of diode laser 810 nm. A young adult female patient was referred for a labial exophytic lesion that continued to grow despite previous topical therapies prescribed by dermatologists. The first dermatologist diagnosed herpetic manifestation and the second diagnosed labial granuloma. The patient has been subjected to ultrasound examination, which confirmed the suspected diagnosis of the benign vascular injury. The patient underwent 3 photocoagulation sessions performed with 810 nm diode laser and after 2 months the lesion completely healed without scarring and without alteration of sensitivity. Lip diseases are often treated dermatologists, although the labial mucosa belongs to the oral cavity. Through the use of a safety device, this type of injury can be managed within the dental office, and so an opportunity for dental practice. The diode laser can be considered safe and effective in the treatment of vascular lesions of the lip.
