The use of dental implants has become a mainstay of rehabilitative and restorative dentistry. With an impressive clinical success rate, there remain a few minor clinical issues with the use of implants such as peri-implant mucositis and peri-implantitis. The use of laser technology with implants has a fascinating breadth of applications, beginning from their precision manufacturing to clinical uses for surgical site preparation, reducing pain and inflammation, and promoting osseointegration and tissue regeneration. This latter aspect is the focus of this review, which outlines various studies of implants and laser therapy in animal models. The use of low level light therapy or photobiomodulation has demonstrated its efficacy in these studies. Besides more research studies to understand its molecular mechanisms, significant efforts are needed to standardize the clinical dosing and delivery protocols for laser therapy to ensure the maximal efficacy and safety of this potent clinical tool for photobiomodulation.

A retrospective study was carried out on 2509 patients with heamorrhoid in which heamorrhoid grade 2, 3 and 4 were 26.8%; 67.5% and 5.7%, respectively. The rate of patients with the circumferential haemorrhoid was 23.2%. All patients received haemorrhoidectomy by laser CO2 and monitored within 1-6 years by direct consultation and survey paper. The results have shown that the technique had a little intraoperative bleeding, little complication, complete outcome and less relapese. The study concluded that the haemorrhoidectomy by laser CO2 was effective and safe method.

Recently, various modalities for noninvasive reduction of adipose tissue, including cryolipolysis, radiofrequency, low-level laser therapy, and high-intensity focused ultrasound, have become available. Among these modalities, cryolipolysisis can selectively target certain tissues rich in lipids. Many preclinical and clinical studies have established the safety and efficacy of cryolipolysis for noninvasive body contouring. However, it can lead to serious adverse effects when performed by untrained clinicians. Thus, to promote the proper and safe use of cyolipolysis, we have summarized the history, basic principles, and adverse effects of cyolipolysis.

Both acquired bilateral nevus of Ota-like macules (ABNOM) and nevus of Ota are characterized by the presence of dermal melanocytes. There are no differences in the method of treatment, however, postinflammatory hyperpigmentation (PIH) develops more often in ABNOM than in nevus of Ota following treatment. We investigated the differences in the development of PIH after treatment between ABNOM and nevus of Ota, and the histopathologic differences in the PIH. A total of 82 patients with ABNOM (n=47) and nevus of Ota (n=35) were treated with Q-switched alexandrite laser and followed up 2 weeks and 3 months later. Biopsies were performed on lesional skin before treatment. The distribution and the amount of melanin pigments were visualized with Fontana-Masson stain, and the distribution and the depth of melanocytes were measured by GP-100 (NK1-beteb) stain. Clinically, there was more erythema and PIH in ABNOM than in nevus of Ota. Histopathologically, intradermal melanocytes were clustered in groups and dispersed perivascularly in ABNOM, while melanocytes were scattered evenly throughout the dermis in nevus of Ota. Both groups show that when there is a statistically significant number of melanocytes in the perivascular area, erythema and PIH occur after laser therapy. In conclusion, indirect vessel injury in addition to perivascular clustering melanocytes might be considered the cause of increased PIH after treatment in ABNOM.

There are several methods for the treatment of herpetic neuralgia, but there is no method that results in complete remission. Laser has lately come into use to reduce several acute or chronic pains. In order to determine the degree of pain relief by lasers, 26 patients of herpetic neuralgia were irradiated with both He-Ne and Ga-Al-As lasers twice to theree times per week and the results were analysed using visual analogue scale. The results were as follows. 1) The improving rate after 15 irradiations of laser was 63% 2)The highest improving rate(24%) was shown after one irradiation of laser(p<0.05). 3) Only one patient above age 60(3.8%) developed postherpetic neuralgia. 4) There was no significant differenc of effects of LLLT between above and below age 60. These results suggest that LLLT is non-invasive and simple method which was effective not only in controlling the herpetic neuralgia but in perventing the postherpetic neuralgia.

Low-level laser or light therapy (LLLT) was used to accelerate wound healing without the use of thermal effects in the early days. Although the exact mechanism of LLLT is still unclear, it has been recognized as a photobiomodulation process. Today, LLLT is being credited as a non-invasive treatment modality, and in particular, being widely applied in the field of dermatology. In this review, we summarize the basic principles and clinical applications of LLLT to provide an up-to-date guidance on its practical and safe uses. Further studies are needed to elucidate the mechanism of action of LLLT in various indications, and to determine the wavelength and dose for optimal clinical use.

In the present study, we evaluated the effect of CGM on osteogenic differentiation of cultured osteoblasts, and determined whether combination treatment with LLLT had synergistic effects on osteogenic differentiation. The results indicated that CGM promoted proliferation, differentiation, and mineralization of osteoblasts at the threshold concentration of 10 µg/ml; whereas, CGM showed cytotoxic properties at concentrations above 100 µg/ml. ALP activity and mineralization were increased at concentrations above 10 µg/ml. CGM in concentrations up to 10 µg/ml also increased the expression of osteoblast-activated factors including type I collagen, BMP-2, RUNX2, and Osterix. The CGM (50 µg/ml) and LLLT (80 mW for 15 sec) combination treatment group showed the highest proliferation levels, ALP activity, and mineralization ratios. The combination treatment also increased the levels of phosphorylated forms of p38, ATF2, PKD, ERK, and JNK. In addition, the osteoblast differentiation factors including type I collagen, BMP-2, RUNX2, and Osterix protein levels were clearly increased in the combination treatment group. These results suggested that the combination treatment of CGM and LLLT has synergistic effects on the differentiation and mineralization of osteoblastic cells.

Low level laser therapy (LLLT) is a therapeutic method which regulates the biological behavior of cells with light. The effects of LLLT consist of promotion of tissue repair, inhibition of inflammation, and relief of pain by promoting or inhibiting the cell proliferation, increasing or decreasing the release of some bioactive substances. Therefore, LLLT is also known as photomodulation. At present, there are many relevant experimental studies of LLLT abroad, and they are also used clinically. This article reviews the effect of LLLT on wound healing.
