Hard dental tissues laser welding: a new help for fractured teeth? A preliminary ex vivo study.

Hard dental tissues laser welding: a new help for fractured teeth? A preliminary ex vivo study. Laser Ther. 2018 Jun 30;27(2):105-110 Authors: Fornaini C, Merigo E, Poli F, Rocca JP, Selleri S, Lagori G, Cucinotta A Abstract Background and Aim: An important surgical goal is to provide a first intention wound healing without trauma produced by sutures and for this aim in the past several methods have been tested. The aim of this ex vivo preliminary study was to demonstrate the capacity of a 1070 nm pulsed fiber laser to treat the dental fractures by enamel and dentine melting with the apposition of hydroxyapatite nanoparticles as filler. Methods: Out of thirty freshly-extracted human third molars, decay-free, twenty-four cylinders of 5 mm thickness were obtained to perform the test.The device used was a 1070 nm Yb-doped pulsed fiber laser: this source has a maximum average output power of 20 W and a fixed pulse duration of 100 ns, while the repetition rate ranges from 20 kHz to 100 kHz. The samples were divided in three groups (a, b, c) of eight teeth and each specimen, with the two portions strictly placed side by side, was put inside the box and irradiated three times, the first and the second at 30 kW and the last at 10 kW peak power (average powers of 60 and 20 W).The repetition rate was maintained at 20 kHz for all the tests as well as the speed of the beam at 10 mm/sec.The samples of the group a were irradiated without apposition, in the group b ...

CONCLUSION: A trend toward increasing use of intravitreal anti-VEGF injections for DME treatment was observed in Korea. However, the frequency of dosing and monitoring was lower in clinical practice versus major clinical trials, which may have led to the less-than-favorable improvements in visual outcomes.

Pattern hair loss is a common diagnosis in clinical dermatology affecting a substantial number of patients, leading to severe psychological and social impact in both men and women. Whereas low-level laser therapy (LLLT) has been known to stimulate cellular activity, there is considerable skepticism from the dermatology community on its use to promote hair growth due to lack of controlled studies, limited understanding of mechanisms, and inadequately defined treatment parameters. For this reason, we sought to examined published clinical trials to clarify uncertainties and determine whether the breadth of evidence supports l...

Huidi Tchero, Christian Herlin, Farid Bekara, Sergiu Fluieraru, Luc TeotIndian Journal of Dermatology, Venereology, and Leprology 2019 85(3):248-257 Hidradenitis suppurativa is a chronic inflammatory condition that affects skin regions bearing apocrine glands. Although hidradenitis suppurativa is difficult to treat and cure, the currently available treatments are directed toward managing the lesions and associated symptoms. This review presents an evidence-based outline of the available treatment options. We searched four electronic databases and extracted data from retrieved studies for qualitative or quantitative analys...

CONCLUSION: Laser therapy for LS caused minimal patient discomfort during the treatment, with no adverse effects, and demonstrated better efficacy than in the control group, with significant improvement lasting up to 6 months. Laser therapy is a promising option for patients not responding to topical corticosteroid therapy or patients wishing to reduce long-term corticosteroid maintenance use.

CONCLUSIONS In operative treatment of AO, swelling aspiration+subcutaneous pruning is the best operative treatment, and botulinum toxin A injection is the best in non-operative treatment. Overall, the effect of surgical treatment was more significant than that of non-surgical treatment. PMID: 30982056 [PubMed - in process]

AbstractFractional 1550-nm erbium-glass (Er:Glass) laser therapy is effective in inducing hair regrowth. Combining fractional Er:Glass laser therapy with topical minoxidil may yield therapeutic benefits for patients with androgenetic alopecia (AGA). To compare the efficacy and safety of fractional Er:Glass laser used in combination with topical 5% minoxidil versus 5% minoxidil alone for the treatment of male AGA, 30 men with AGA were randomized to 24  weeks of split-scalp treatment using fractional Er:Glass laser and 5% minoxidil on one side (combined therapy) or 5% minoxidil alone on the other side (monotherapy). The...

AbstractSeveral therapeutic strategies have been proposed to optimize the conventional treatment of fractures. Photobiomodulation (PBM) appears to help reduce pain and control inflammation, and it also accelerates bone repair. This systematic review aimed to evaluate the effectiveness and safety of PBM with low-level laser therapy (LLLT) in the bone fracture healing process. We included randomized controlled trials (RCTs) comparing the effects of PBM with those of any other intervention in adults with lower or upper limb bone fractures. The primary outcomes investigated were pain reduction, radiographic healing, and advers...

Erica S. Tarabadkar† and Michi M. Shinohara*† Division of Dermatology, University of Washington, Seattle, WA, United States Skin directed therapies (SDTs) serve important roles in the treatment of early stage cutaneous T-cell lymphoma (CTCL)/mycosis fungoides (MF), as well as managing symptoms and improving quality of life of all stages. There are now numerous options for topical therapies that demonstrate high response rates, particularly in early/limited MF. Phototherapy retains an important role in treating MF, with increasing data supporting efficacy and long-term safety of both UVB and PUVA as ...
