Low Level Laser Therapy

A pilot study to assess the efficacy and feasibility of PBMT for pain control in patients undergoing a TKA and are discharged the same day from an ambulatory surgery center.

Orthodontic treatment is often prolonged, requiring years to achieve desirable outcomes. The prolonged duration of treatment increases the risk of complications such as root resorption, periodontal damage, and patient non-compliance. To address these concerns, various methods have been explored to accelerate orthodontic tooth movement, including pharmacological agents, mechanical vibration, corticotomies, and minimally invasive techniques like Micro-Osteoperforations (MOPs) and Low-Level Laser Therapy (LLLT). Micro-Osteoperforations (MOPs) have gained popularity as a minimally invasive technique that enhances bone remodeling by inducing a localized inflammatory response, thereby accelerating tooth movement. Studies have shown that MOPs can effectively stimulate the expression of cytokines, increasing osteoclastic activity and facilitating rapid orthodontic tooth movement. However, the extent of its effectiveness varies among individuals, necessitating additional interventions to maximize efficiency. Low-Level Laser Therapy (LLLT), also known as photobiomodulation, is another promising adjunct in orthodontics. LLLT has been reported to enhance cellular activity, promote osteoblastic and osteoclastic function, and improve tissue healing, leading to accelerated tooth movement. Several studies suggest that LLLT alone can expedite orthodontic treatment, but its combination with MOPs has not been extensively explored. This study aims to compare the rate of orthodontic tooth movement between MOPs alone and MOPs combined with LLLT. By evaluating these two techniques, this research seeks to determine whether LLLT enhances the effectiveness of MOPs in accelerating tooth movement. The findings of this study could provide valuable insights into optimizing orthodontic treatment duration while minimizing potential risks and discomfort for patients.

Impacted lower third molar extraction is one of the most commonly performed dental procedures in daily practice. However, this is considered a relatively invasive procedure. During the surgery, dental surgeon must reflect a full-thickness flap, remove bone to expose the tooth, section and deliver the tooth. As a result, after surgery, patients often experience many complications, from swelling, pain, jaw tightness, etc. to alveolar bone loss, periodontal problems distal to the second molar, etc. Therefore, clinicians are always looking for additional therapies to minimize complications, helping patients have a more comfortable experience after wisdom tooth surgery. To date, placing grafting materials such as bone or other biological materials (growth factors, platelet-rich plasma, platelet-rich fibrin) into the tooth socket has been shown to be able to preserve the alveolar crest after extraction. However, these materials require preparation time, are costly, and have the risk of infection related to bone grafts. Meanwhile, low-level laser therapy (LLLT) is known as a safe, non-invasive therapy that can affect cell metabolism without causing tissue damage. This therapy has been widely applied in many fields of medicine in general and in dentistry in particular. Low-level lasers have been studied to help reduce swelling, pain, and jaw tightness after impacted lower wisdom teeth surgery. In vitro or in vivo studies evaluating the healing effect of low-level lasers have given very positive results. However, there is still a lack of scientific evidence to prove the healing effect of low-level lasers on human tooth extraction sockets. The study we conducted is a scientific study, in the field of Dentistry. This study aimed to evaluate the effectiveness of low-level laser on soft tissue and bone healing after surgical extraction of impacted lower third molars in a group of Vietnamese population.

Tooth extraction may be an unpleasant and painful experience for children, Post-extraction wound healing. Low-level laser therapy (LLLT) is a widely used adjuvant treatment for wound healing, resulting in both an increase in cell number and an increase in cell metabolism. HA it is an important component of the extracellular matrix and a constituent of the neural, connective, and epithelial tissues.

It was designed as a single-center, prospective, randomized controlled study. The study consists of two groups. Both groups of patients will receive a conventional home based exercise program. In addition to the conventional exercise program, patients in the first group will also receive low-level laser therapy (LLLT). If the laser group is found to be superior at the end of the study, the patients who only received the exercise program will be recalled and administered LLLT. Patients who meet the inclusion criteria will be enrolled in the study. Sample size calculations were based on data from a previous study by Alghadir et al. Using a mean of 3.25 and a standard deviation of 2.61 for the WOMAC pain subscale, the number of participants was calculated with 95% power and a 5% significance level. As a result, it was determined that at least 29 patients would be included in each group. Written informed consent will be obtained from each patient before enrollment. Randomization will be performed according to the order of patient admissions. Patients will be evaluated before treatment, and at the 1st and 3rd months post-treatment. The dosage of laser application was selected based on the recommendations of the World Association for Photobiomodulation Therapy (WALT). Patients will be treated 5 sessions per week for 2 weeks. The treatment will be applied using the BTL SMART 4000 laser device at a wavelength of 835 nm and a dose of 10 J/point. The conventional home based exercise program includes: range of motion (ROM) exercises, stretching, strengthening, relaxation and aerobic exercises. The program will begin with ROM, stretching, relaxation, aerobic, and isometric strengthening exercises. After one week, concentric and eccentric strengthening exercises will be added using elastic bands. The home exercise program will be performed 3 days a week, each exercise in 3 sets of 10 repetitions and 2 minutes of rest between sets. Aerobic walking at a moderate pace for 30 minutes will be recommended. Each patient will be shown and taught the exercises to be performed at home, and will also be provided with illustrated instructions. The home based exercise program will continue for 12 weeks. Patients will be contacted by phone weekly during the first month, and then every two weeks thereafter, to assess their adherence to and continuation of the home based exercise program. Before starting treatment, demographic information will be collected, medical history will be taken, and a physical examination will be performed. Pre-treatment evaluations include: * Measurement of height, weight, and calculation of body mass index (BMI) * Femoral cartilage thickness and quadriceps muscle thickness measurement via ultrasound * Determination of the Sonographic Thigh Adjustment Ratio (STAR) * Application of the SARC-F screening test; those scoring over 4 will undergo whole-body muscle mass measurement * Handgrip strength (HGS) measurement using a Jamar hand dynamometer * Five-times chair stand test (CST) * Timed Up and Go (TUG) test * Six-minute walk test * Visual Analog Scale (VAS) for pain * Western Ontario and McMaster Universities Arthritis Index (WOMAC) * Short Form-36 (SF-36) quality of life questionnaire Post-treatment evaluations (At the end of the 1st month and at the end of the 3rd month) include: * Calculation of body mass index (BMI) * Femoral cartilage thickness and quadriceps muscle thickness (USG) * STAR index calculation * Handgrip strength using Jamar dynamometer * Five-times chair stand test * Timed Up and Go test * Six-minute walk test * Visual Analog Scale (VAS) for pain * WOMAC * SF-36 Quality of Life Questionnaire

Diabetic foot ulcers (DFU) are among the late complications of DFU, defined as skin lesions that involve the dermis to deeper structures, such as muscles and bones. Although preclinical studies have demonstrated the effects of GaAs 830 nm in diabetic wounds, no clinical studies have been performed, revealing the need for more in-depth analyses to identify the effects and ideal parameterization of PBM with GaAs 830 nm wavelength in the treatment of diabetic ulcers, improving quality of life, as well as to understand the therapeutic feasibility, time required for healing and recurrence rates of these lesions. Experimental, randomized, controlled, double-blind study, with blinding applied to the evaluator and participants. A total of 136 volunteers will be recruited for the research, carried out at the Integrated Center of Medical Specialties (CIEM) - Polyclinic.
