Low level laser therapy and hair regrowth: an evidence-based review

Cardiac rehabilitation is one of the main achievements of cardiology and physical rehabilitation medicine in the second half of the 20th century. Based on the methodology of evidence-based medicine, cardiac rehabilitation in a short time evolved from a “fictional” “alternative” unproven treatment direction to completely uncontested and proven multidisciplinary programs. This article presents contemporary findings on cardiorehabilitation and analysis of evidence-based experimental and clinical studies of low-level laser therapy efficiency in patients with ischemic heart disease. Aim. To search for evidence-based investigations on application of low-level laser therapy for rehabilitation of patients with ischemic heart disease and to analyze their major propositions and recommendations.Materials and methods. PEDro, EMBASE, PubMed and Cochrane library electronic databases were searched for randomized clinical trials, systematic reviews, meta-analyses and clinical protocols using the key words within 2000–2019 years. Results and discussion: experimental and clinical investigations were carefully considered and the following findings were analyzed: action mechanisms of low-level laser therapy, its positive influence on myocardial remodeling, infarction area reduction, restenosis prevention and presented cardioprotective effect. More attention was focused at clinical evidence-based studies on application of photobiomodulation in order to increase the efficacy of surgical and percutaneous myocardial revascularization, and in non-invasive cardiology and physical rehabilitation medicine. Conclusion: regular analysis of performed studies and realization of new evidence-based investigation should be conducted to evaluate the efficiency of low-level laser therapy in rehabilitation of patients with ischemic heart disease.

The purpose of this study was to evaluate whether Low-Level Laser Therapy (LLLT) improves the healing of the implant surgical site with clinical and biochemical parameters.Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to two groups - the control group and the test group. The test group received laser energy at a power of 2J/cm 2 with a total of 4-6J energy over each implant. Clinical parameters (Implant Stability Quotient, probing index, modified sulcus bleeding index)and osteoprotegerin (OPG) were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months).The test group showed significantly higher implant stability quotient compared to thecontrol group at 2 weeks(57.93±3.95 and 35.67±3.08; p<0.01) and 3months(58.86±3.75 and 67.06±3.78; p<0.01). A significant rise in OPG levels of the test group(686.30±125.36pg/ml at baseline and 784.25±108.30pg/ml at 3months;p<0.01) was seen contrary to significant decline in the control group (839.50±249.08pg/ml at baseline,415.30±78.39pg/ml at 3months;p<0.01). Within the limitations of the study, the study suggests that the healing of peri-implant hard and soft tissues may be enhanced with the use of LLLT as an explicit modality during the post-operative period.
