Abstract Objective: To evaluate and compare the analgesic effects of caudal epidural administration of lidocaine (LIDO), caudal laser radiation and epidural lidocaine plus laser radiation in horses. Study design: A blinded, randomized, prospective, experimental cross-over study. Animals: Five healthy horses, 15.7 +/- 4.9 years of age, weighing 240 +/- 37 kg. Methods: The...

introduction: periodontitis is an inflammatory periodontal disease that leads to tooth loss. recently laser has been introduced as an alternative treatment for periodontitis. the aim of the present study was to compare the effect of erbium-doped yttrium aluminum garnet (er:yag) laser with ultrasonic scaler in patients with moderate chronic periodontitis. methods: in this randomized single-blind...

background: the effectiveness of low power lasers on incisional wound healing, because of confl icting results of previous studies, is uncertain. therefore, the aim of this study was to evaluate the effects of low-level helium-neon (he-ne) laser irradiation on wound healing in rat’s oral mucosa. materials and methods: sixty-four standardized incisions were carried out on the buccal mucosa of 32...

introduction: the aim of this study is to evaluate the effects of low-level neodymium-doped yttrium aluminium garnet (nd:yag) laser irradiation on orthodontic tooth movement and histological examination. methods: eleven male wistar rats (aged 10 weeks) were included. to produce experimental tooth movement in rats, 10 g force was applied to maxillary first molars with nickel titanium closed coil...

This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...

The statistics of the light emitted by two-level lasers is evaluated on the basis of generalized rate equations. According to that approach, all fluctuations are interpreted as being caused by the jumps that occur in active and detecting atoms. The intra-cavity Fano factor and the photo-current spectral density are obtained analytically for Poissonian and quiet pumps. The algebra is simple and ...

introduction: low back pain (lbp) is the most common musculoskeletal disease. monochromatic infrared photo energy (mipe) and low level laser therapy (lllt) are light modalities used to reduce pain and increase blood flow. the aim of this study was to compare the effects of the mipe and lllt in reducing functional disability and pain as well as improving lumbar range of motion (rom) in patients ...

The LLLT literature is large, with more than 1000 papers published on this topic. A problem in dissecting this literature is the variation in methodology and dosimetry between different studies. Not only have a range of different wavelengths been examined, but exposure times and the frequency of treatments also vary. The inclusion of sham-irradiated controls in clinical studies is an important ...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...
