“…Recently, it has also found use in perioral aesthetics, such as in wrinkles or vascular lesions. Regarding oral soft tissue pathologies, the laser has found various uses over the years, as a device to make biopsy samples, or it can be used for the ablation of keratotic lesions or to photocoagulate vascular lesions or in photobiomodulation [1][2][3][4].…”

Continuously evolving laser devices can be used in various fields; they are an alternative to the traditional cold blade surgery to perform biopsies of oral soft tissues. The aspect focused on in this paper is the possibility to use the 445 nm diode laser (Eltech K-Laser srl, Treviso, Italy) in complete safety, by evaluating its thermal effects during microscopy. A histological evaluation of the alteration of the peri-incisional edges on 10 samples was realized. All excisional biopsies were related to clinically unsuspected lesions and performed by the same expert operator. The surgical procedure was performed with the same laser parameters and the same pathologist evaluated the thermal effect on the samples. An average value of the detected tissue alteration was calculated; the average damage of the epithelium was 650.93 μm, while in the connective tissue it was 468.07 μm. In all the cases a clear diagnosis was possible, and no clinical complications were observed; so, the 445 nm diode laser proved to be a device that can be safely used for biopsies of clinically unsuspicious lesions. Due to the small number of cases, this in vivo preliminary experience needs to be extended.

“…In addition, it caused an increase in tissue temperature (100% duty cycles, 79 • C; dT/dt, 7.43 • C) to the level enabling effective coagulation thereof. It can be applied in the treatment of shallow vascular lesions on mucous membranes, for which other laser systems are also used [34,35]. The diode lasers used most frequently in these cases are the lasers ranging from 800 nm to 980 nm as such wavelength is within one of the three absorption peaks for haemoglobin [29,36].…”

Background: Lasers are widely used in medicine in soft and hard tissue surgeries and biostimulation. Studies found in literature typically compare the effects of single-wavelength lasers on tissues or cell cultures. In our study, we used a diode laser capable of emitting three components of visible light (640 nm, red; 520 nm, green; 450 nm, blue) and combining them in a single beam. The aim of the study was to assess the effects of laser radiation in the visible spectrum on tissue in vitro, depending on the wavelength and pulse width. Methods: All irradiations were performed using the same output power (1.5 W). We used various duty cycles: 10, 50, 80 and 100% with 100 Hz frequency. Maximum superficial temperature, rate of temperature increase and lesion depth were investigated. Results: Maximum superficial temperature was observed for 450 + 520 nm irradiation (100% duty cycle). The highest rate of increase of temperature was noted for 450 + 520 nm (100% duty cycle). Maximum lesion depth was observed in case of three-wavelength irradiation (450 + 520 + 640 nm) for 100, 80 and 50% duty cycles. Conclusions: The synergistic effect of two-wavelength (450 + 520 nm) irradiation was observed in case of maximum temperature measurement. The deepest depth of lesion was noted after three-wavelength irradiation (450 + 520 + 640 nm).

“…The laser treatment of oral vascular lesions seems to be an excellent device, and different wavelengths have been reported in the literature. In a recent study, the Neodymium laser was used to successfully treat 93 patients with labial lesions, without any collateral damage, with a maximum of 2 sessions [14]. Bacci et al performed laser therapy sessions on 59 patients with labial vascular pathologies, performing only 6 cases of additional treatments with negligible side effects [13].…”

“…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.
