“…Consistent with previous studies, scalpel incisions are superior, with statistically significant increased tensile strength and histological maturation compared with laser incisions made without the use of any template. [1][2][3][4][5][6][7][8][9] With utilization of heat-conducting templates, wound healing after laser incisions more closely approximates scalpel incisions. The sapphire template approximated the metal templates in efficacy, but was slightly less effective than the scalpel incisions.…”

“…Unfortunately, laser use has been limited by the thermal damage produced, which has been shown to delay and/or impair wound healing. [1][2][3][4][5][6][7][8][9] The development of devices that reduce the wound healing delay after laser incisions is important for making laser incision surgery clinically practical. Various strategies, in addition to a multitude of studies using various wavelengths of light, 10,11 have been tried to limit this delay in wound healing.…”

We have previously shown a reduction in lateral thermal damage with acute studies of skin incisions made in vitro using heat-conducting templates. Here we examined the wound-healing response to laser incisions with heat-conducting templates and explored the use of an optically transparent template with the free electron laser (FEL) at 6.45 microm. First we evaluated the effects of a sapphire heat-conducting template on the lateral thermal damage of FEL incisions using in vitro human skin samples. Next we compared wound tensile strength and histological scoring of the healing of incisions created on the dorsal pelts of live rats with the FEL utilizing metal and sapphire heat-conducting templates and scalpel incisions. The animals were euthanized and the wounds were analyzed at postoperative days 7, 14, and 21. The depth and lateral thermal damage of FEL incisions on in vitro human skin were significantly reduced with the sapphire heat-conducting template. Nonstatistically significant differences in wound tensile strengths and histological scoring of wound healing were noted at days 7 and 14. By day 21, all of the incisions appeared similar. When the data from days 7 and 14 were combined, statistically significant differences were found for each of the templates (except the histological evaluation with the aluminum template) and the scalpel compared with laser incisions made without using a template. The use of metal or sapphire heat-conducting templates reduced the wound-healing delay of laser incisions seen at postoperative days 7 and 14.

“…The analysis of the literature shows that laser treatment represents a procedure with minimal short-and long-term morbidity [22][23][24]. The laser is also well accepted in paediatric patients [25]. The possible problems of such a tool are the inflammation in the incisional area, the control of thermal modifications, and the quality of excised tissues [26][27][28].…”

810nm, 980nm, 1470nm and 1950nm diode laser comparison: a preliminary “ex vivo” study on oral soft tissues

et al. 2015

The introduction of diode lasers in dentistry has several advantages, mainly consisting on the reduced size, reduced cost and possibility to beam delivering by optical fibers. At the moment the two diode wavelengths normally utilized in the dental field are 810 and 980 nm for soft tissues treatments. The aim of this study was to compare the efficacy of four different diode wavelengths: 810, 980, 1470 and 1950 nm diode laser for the ablation of soft tissues. Several samples of veal tongue were exposed to the four different wavelengths, at different fluences. The internal temperature of the soft tissues, in the area close to the beam, was monitored with thermocouple during the experiment. The excision quality of the exposed samples have been characterized by means of an optical microscope. Tissue damages and the cut regularity have been evaluated on the base of established criteria. The lowest thermal increase was recorded for 1950 nm laser. Best quality and speed of incision were obtained by the same wavelength. By evaluating epithelial, stromal and vascular damages for all the used wavelengths, the best result, in terms of "tissue respect", have been obtained for 1470 and 1950 nm exposures. From the obtained results 1470 and 1950 nm diode laser showed to be the best performer wavelengths among these used in this "ex vivo" study, probably due to their greatest affinity to water.

“…Photobiological effects of helium-neon (HeNe) and gallium-arsenide (GalAs) lasers and their interaction with the immune system are well defined [9]. LLL have a long history in wound healing [10][11][12][13][14][15][16][17][18][19]. Their effect on cellular [16,20] and inflammatory processes [21], such as rheumatoid arthritis and osteoarthritis, have already been reported [22,23].…”
