introduction: post-endodontic treatment pain is a relatively common condition which needs analgesics for patient’s pain relief. low-level laser therapy (lllt) is suggested as a non-pharmacological and non-invasive treatment for dealing with painful conditions. the purpose of this study was to evaluate the pain relief effect of lllt after endodontic treatment. methods: eighty patients randomly r...

The ability to modify the character of fluorescent emission by a laser-controlled, optically nonlinear process has recently been shown theoretically feasible, and several possible applications have already been identified. In operation, a pulse of off-resonant probe laser beam, of sufficient intensity, is applied to a system exhibiting fluorescence, during the interval of excited-state decay fo...

BACKGROUND AND AIMS Our hospital has used LLLT in the treatment of athletes since 1990. We had a good result about LLLT for sports injuries. However, few articles have attempted to evaluate the efficacy of LLLT for sports injuries. The aims of this study was to evaluate the efficacy of LLLT for sports injuries. Materials (Subjects) and Methods: Forty one patients underwent LLLT in our hospital....

Lymphoedema Service, Wolverhampton; Module Leader of Lymphoedema Degree at Compton Hospice and Trainer and Director of Leduc UK Laser has been used for the management of lymphoedema and other conditions for many years. Since attending the Australasian conference in Adelaide in 2002, laser treatment has appealed to the author as an adjunctive therapy. Due to the absence of the UK ‘CE’ mark, it c...

Low level laser therapy is defined to supply direct biostimulative light energy to the cells .It has been reported that low-level semiconductor diode lasers could enhance the wound healing process. The periodontal ligament is crucial for maintaining the tooth and surrounding tissues in periodontal wound healing. Low-level semiconductor diode lasers have been used in low-level laser therapy ,the...

KANJ, HOUSSAM. Circuit-Level Modeling of Laser Diodes. (Under the direction of Dr. Michael B. Steer.) In all semiconductor laser diodes the thermal, electrical, and optical characteristics are integrally related. In this work, a new approach to the modeling of laser diodes that integrates electrical, optical and thermal effects is presented. Also, it is demonstrated how physical device models b...

The use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. This review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

Low Level Laser Therapy (LLLT) uses a light source that generates extremely pure light, of a single wavelength(1). The effect is not thermal, but rather related to photochemical reactions in the cells. LLLT was introduced as an alternative non-invasive treatment for OA about 10 years ago, but its effectiveness is still controversial(2). A Cochrane review of LLLT in osteoarthritis included five ...

Low-level laser therapy (LLLT) is a newly developing technique in dentistry, although it has been used among medical, dental, physiotherapy, and veterinary professions in some parts of the world for decades. LLLT can offer tremendous therapeutic benefits to patients, such as accelerated wound healing and pain relief. There is much to be learned about the mechanisms, recognition of the therapeut...
