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 single root teeth and not adjacent to each other. The subordinated teeth were randomized into four groups, as follows: no treatment (C group), simple SRP (SRP group), Nd: YAG laser after SRP treatment (SRP+L group), and SRP after Nd: YAG laser treatment (L+SRP group)...

Erbium-doped yttrium aluminum garnet (Er3+:YAG) rods were inserted inside undoped tubes and grown into single-crystal fibers of a diameter of 300 μm using the laser-heated pedestal growth technique. Growth at various rates resulted in radially graded distributions of Er3+ dopant ions, as observed using laser-induced fluorescence imaging. Profiles of the refractive index were measured using cross-sectional reflectometry in a microscope. Dopant distributions and the corresponding index profiles were compared with thermal diffusion theory to determine the inter-diffusion coefficient of Y3+ and Er3+ ions at 2000°C, yielding an estimated value of D=(9...

Several techniques have been proposed to obtain a durable bond, and the efficacy of these techniques is assessed by measuring parameters such as bond strength. Laser has provided a bond strength as high as that of acid etching in vitro and has simpler use with shorter clinical time compared to acid etching. This study aimed to compare the efficacy of Er:YAG and Er,Cr:YSGG lasers for etching and bonding of composite to orthodontic brackets. No previous study has evaluated the effect of these particular types of laser...

When attempting to clean surfaces of dental root canals with laser-induced cavitation bubbles, the resulting cavitation oscillations are significantly prolonged due to friction on the cavity walls and other factors. Consequently, the collapses are less intense and the shock waves that are usually emitted following a bubble's collapse are diminished or not present at all. A new technique of synchronized laser-pulse delivery intended to enhance the emission of shock waves from collapsed bubbles in fluid-filled endodontic canals is reported...

Hyperhidrosis o`ccurs when the body produces sweat beyond what is essential to maintain thermal homeostasis. The condition tends to occur in areas marked by high-eccrine density such as the axillae, palms, and soles and less commonly in the craniofacial area. The current standard of care is topical aluminum chloride hexahydrate antiperspirant (10-20%), but other treatments such as anticholinergics, clonidine, propranolol, antiadrenergics, injections with attenuated botulinum toxin, microwave technology, and surgery have been therapeutically implicated as well...

Recall erythema is a phenomenon occurring when an area of epidermis treated with laser is later exposed to a trigger, most often sunlight or hot water, causing erythema in the zone of laser treatment after post-treatment erythema has already resolved. Radiation recall dermatitis is a more specific subtype of recall erythema in which an area treated with radiation is subjected to another exposure causing erythema in the area of previous radiation. Cases of recall dermatitis after laser treatment are extremely rare and have only been reported with diode neodymium-doped yttrium aluminum garnet lasers...
