Demineralized enamel grooves were exposed to an acid gel at pH=5 for 3weeks after irradiation with a KrF excimer laser with a wavelength of 248nm (total energy dose= 172 J/cm2) er with the second harmonic wave of a Q-switched Nd:YAG laser with a wavelength of 532nm (totai energy dose=100JIcm2), The mineral distributions were assessed quantitatively by transversal microradiography. Compared with...

introduction dentine hypersensitivity is a common clinical problem in dental practices. so several methods such as, nd: yag laser have been used to treat this problem. previous studies reported that nd:yag laser irradiation on root surface makes some thermal changes, like dentine melting and some other side effects which are related to power of laser irradiation. the aim of our study was to com...

BACKGROUND To report the negative effect of Nd: Yag (Neodymium-doped: Yttrium Aluminium Garnet) laser capsulotomy on the intraocular pressure (IOP) and the trabeculectomy bleb integrity, in a small series of eyes, both trabeculectomised and pseudophakic, following the laser application for the management of posterior capsular opacification (PCO). METHODS This is a retrospective, non-comparati...

OBJECTIVE Our research aimed to detect the efficacy of non-surgical periodontal treatment with Nd: YAG laser and scaling and root planning (SRP) for chronic periodontitis. METHODS We recruited chronic periodontitis patients who have more than four teeth with clinical pocket depth of 4-8 mm. These teeth were distributed in four different zones within the oral cavity. Moreover, the teeth were s...

BACKGROUND Acne scarring is treatable by a variety of modalities. Ablative carbon dioxide laser (ACL), while effective, is associated with undesirable side effect profiles. Newer modalities using the principles of fractional photothermolysis (FP) produce modest results than traditional carbon dioxide (CO(2)) lasers but with fewer side effects. A novel ablative CO(2) laser device use a technique...

BACKGROUND Axillary hyperhidrosis is a common but difficult-to-treat condition with major social, labor, and emotional consequences. OBJECTIVE The aim of this study is to present the Nd-YAG laser as a safe and effective option for the treatment of axillary hyperhidrosis. MATERIALS AND METHODS From January 2002 to April 2007, 17 patients (15 women and 2 men) with axillary hyperhidrosis were ...

Intratracheal combustion of a fiberoptic bronchoscope and an endotracheal tube occurred during the treatment of severe tracheal stenosis with the neodymium-YAG laser. This recognized hazard of CO2 laser surgery has not been reported previously with the use of the Nd-YAG laser. Fire hazard is inevitable when a laser is used in the airway, but the risk can be diminished. Rapid removal of the burn...
