introduction: the aim of this study was to evaluate and compare the scanning electron microscope (sem) of indirect composite conditioned by erbium-doped yttrium aluminum garnet (er:yag) laser, neodymium-doped yttrium aluminium garnet (nd:yag) laserand carbon dioxide (co2) laser. methods: 18 indirect composite blocks (gc gradia da2, japan) with 15 × 10 × 10 mm dimensions were made. the bonding s...

Objectives: Palmoplantar warts are a challenge to treat. Standard treatment methods include electrocautery, radiofrequency ablation and cryosurgery, carbon dioxide laser, Erbium-doped Yttrium Aluminum Garnet which ablative, invasive, have downtime. Non-ablative lasers like pulsed dye laser long-pulsed Neodymium: Yttrium-Aluminum-Garnet (Nd: YAG) been tried earlier for the of overcome these defi...

statement of problem: the achievement of a good and durable dentin/composite resin bond is an important task in restorative dentistry. the application of acid conditioners and dentin bonding agents is an accepted method to enhance this bond strength. pretreating of dentin surface by laser irradiation seems to be a supplemental way to obtain better results, since lased dentin is more roughened a...

The Nd-YAG laser has good tissue penetration and coagulation effects thus has become an important weapon for photoresection of tracheobronchial obstructive lesions since 1980.Treatment of benign lesions including benign tumors and scar tissues using the Nd-YAG laser has good results. In the treatment of malignant tumors however, it has a lower effectivity rate when compared to benign lesions. F...

BACKGROUND Hirsutism means excessive terminal hair growth in a female in male pattern distribution. Perception of hirsutism is subjective. Permanent laser hair reduction is a slow process taking many sessions and tracking of improvement parameters is tedious. Hence, a lot of confusion still exists regarding the type of laser most beneficial for treatment. AIM The aim of this study was to comp...

graphene oxide was prepared using modified hummers method. stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. nd: yag pulsed laser was applied to prepare reduced nanofluids. experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (go) in ethylene glycol. the enhancement ratio of...

introduction: dentine hypersensitivity (dh) is characterized by a short sharp pain arising from the exposed dentine, in response to a thermal, evaporative, tactile, osmotic or chemical stimulus. the aim of this study was to evaluate the efficacy of nd:yag laser therapy and desensitizing gel (sensikin®, laboratorios kin s.a., barcelona, spain) in treatment of dentine hypersensitivity. methods: a...

BACKGROUND Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-a...
