Objective: The aim of this study was to compare the scanning electron microscopic (SEM) morphology of root canal walls instrumented manually and mechanically with and without the application of Er:YAG laser. Methods: Single-rooted, human, extracted teeth were cut at the cementoenamel junction....
Objective: This in vitro study evaluated the effects of Nd:YAG and Er:YAG lasers on reducing dentin permeability by sealing opened tubules. Background Data: According to hydrodynamic theory, dentine hypersensitivity occurs when dentin is exposed with tubules opened. Consequently, a painful...
Objective: The aim of this study was to examine the effect of He-Ne and nitrogen lasers on the apoptosis of PMN in normal versus burn patients. Background Data: Nitrogen and He-Ne laser exposure increases the apoptotic death rate for human macrophages. Inflammation is a major consequence of...
Objective: The objective of this study is to investigate the effect of low-power gallium-arsenide laser treatment on the patients with shoulder pain. Backround Data: Low-energy laser therapy has recently been popularized in the treatment of various rheumatologic, neurologic, and musculoskeletal...
Objective: This study aimed to describe, through morphologic and cytochemical analysis, the healing process of wounds submitted (or not) to laser therapy (λ685 nm) or polarized light (λ400–2000 nm). Background Data: There are many reports on different effects of several types of...
Objective: A 325-nm ultraviolet (UV) laser was tested for effectiveness in the detection of incipient carious lesions on teeth. Background Data: The combination of early detection with new intervention methods and caries management will be the preferred dentistry of the future. Methods: Carious...
Objective: The aim of this study was to provide a retrospective analysis of treatment that combines the laser and the endoscope. Background Data: Previously, surgeons faced many complications arising from endoscope-assisted surgery in the region of the forehead. In order to reduce the incidence...
Objective: The objectives of this study were to observe morphological changes of root canal walls and to evaluate the capability of Er,Cr:YSGG laser for preparation of curved mandibular incisor root canals in vitro . Background Data: There are no published reports on the use of Er,Cr:YSGG laser...
Objective: The aim of this study was to test if a conclusion in a systematic review of low-level laser therapy (LLLT) for osteoarthritis from the Cochrane Library was valid and robust. Background Data: Health policy decisions often rely on conclusions from the Cochrane Database of Systematic...
Objective: This study was conducted to analyze the effect of different irradiances of low-level laser therapy (LLLT) on angiogenesis after partial rupture of Achilles tendon of rats. Background Data: . . . Methods: Ninety-six animals were divided into three groups subject to treatment during 3,...
