Aim: This study aimed to compare the effect of low-level laser therapy irradiation with two different wavelengths after osteotomy site preparation on the stability of dental implants. Materials and Methods: The current study is a double-masked, randomized clinical trial. A total of seven patients of age 25 to 55 years were assigned randomly into two groups. Group I: Osteotomy site irradiated with low-level laser therapy of wavelength 940nm. GROUP II: Osteotomy site irradiated with low-level laser therapy of wavelength 660nm. Implant stability was measured after implant placement using the Penguin RFA device. Bone formation was assessed with Cone Beam Computed Tomography. Results: The current trial results showed that low-level laser therapy aided in bone formation around the implants, but there is no significant difference between the two different wavelengths. Conclusion: Implant stability increased in both groups, but no difference is observed among the groups. Hounsfield units indicating bone formation improved in both the groups with no pronounced difference between the groups. All 14 implants were stable, thus indicating that low-level laser therapy aids bone formation, but the wavelength difference had no significant impact.

Canine Osteoarthritis

Background: Osteoarthritis (OA) is common in dogs and causes chronic pain that affects the quality of life and may not respond to analgesics.Objective: The objective of this study was to determine whether low-level laser therapy (LLLT) would improve the quality of life and help reducing systemic analgesics, in dogs with OA.Methods: Seventeen client-owned dogs diagnosed with OA and associated pain were included. The diagnosis of OA was confirmed by orthopedic and radiographic examination. Pain was evaluated in each dog with the canine brief pain inventory (CBPI), compiled by the dog owners, as well as with a visual analog scale (VAS) and the colorado state canine chronic pain scale, used by the clinician. The LLLT was performed weekly in each study dog, for a total period of 6 weeks. The CBPI was then repeated at 2, 4, 6, and 8 weeks after the first laser session, whereas the VAS was reassessed at weeks 2 and 6. The dogs were observed for the occurrence of laser-related side effects.Results: Both CBPI and VAS were significantly reduced after the first laser session (9.2 ± 3.8 and 5.2 ± 1.1, respectively) compared to pretreatment values (11.8 ± 3.6 and 7.6 ± 0.9, respectively; and p = 0.018 and p < 0.001, respectively) and continued to decrease over time until the end of the therapy. Based on these results and improved function, as assessed by the orthopedic surgeon, the pharmacological analgesic therapy was reduced by the clinician at week 2 in 13 of 17 dogs. Laser-related side effects were not observed.Conclusion: This retrospective report provides a basis for future investigations, needed to clarify whether laser therapy may be beneficial to treat canine OA-associated pain. The preliminary findings are promising and suggest that LLLT may help reducing the analgesic administration and improving client satisfaction and the quality of life of dogs with OA.

The aim of this study is to assess the histological efficiency of low level laser therapy (LLLT) with respect to the acceleration of bone regeneration after surgical treatment of intrabony defects. Twenty patients with intrabony defects, aged between 20-45, non-smokers, good health condition present at the time of the surgery, were randomly divided in two groups, control, ten parients, and test group, ten patients. Informed consent was obtained. Each patient presented at least one periodontal defect treated by bone allograft. The test group received postsurgical treatment with low lever laser therapy (LLLT). The equipment used was OsseoPulse AM300, at an intensity of 20mW/cm2, for 20 minutes per day, for 21 consecutive days. The control group received no treatment with LLLT. The bone formation was evaluated in both groups at baseline and 6 months postoperative by the means of tissue biopsy followed by a histological analysis. The histological study of the test samples at 6 months after regeneration showed bone formation without inflammatory cells and occasional nonviable bone consistent with regenerating bone. No evidence of the grafted material was present. The histological study suggests that in 6 months there was new bone formation in the defects treated with LLLT. Clinical data indicate the possibility of more rapid wound closure and subsequent healing in zones treated with LLLT as compared with control.
