introduction: periodontal diseases are considered as some of the most common reasons of teeth loss, which occur due to the aggregation of microbial plaque and other precipitations on the dental surfaces . in this study, the scaling effect using manual tools, ultrasonic machine and erbium-doped yttrium aluminum garnet (er:yag)laser on the connection of the human gums connective tissue cells on t...

The sensitivity of a force sensor based on photo-elastic effect in a monolithic Nd-YAG laser depends strongly on the geometrical shape and dimensions of the laser medium. The theoretical predictions of sensitivity are in good agreement with first results obtained with a plano-concave cylindrical crystal of (4×4) mm and some values reported by other groups. However, for small size of the laser s...

BACKGROUND This study examined the effect of roughening of the root surface using an erbium-doped yttrium aluminum garnet (Er: YAG) laser on the binding strength of teeth undergoing root canal treatment. MATERIAL AND METHODS Ninety single-rooted teeth were used and assigned randomly to 9 groups (n=10 each). Root canals were prepared using the FlexMaster rotary system. An Er: YAG laser was appli...

Introduction: Our aim was to compare two types of lithotripter including holmium: YAG laser and pneumatic one in transurethral ureterolithotripsy (TUL) for the management of ureteral calculi ≥1 cm. Methods: 112 patients with ureteral calculi more than 1 cm were selected in randomized order for pneumatic or holmium: YAG laser transurethral ureterolithotripsy (56 patients in each group). Ultrason...

An unusual case of endobronchial Kaposi's sarcoma causing right middle and lower lobe atelectasis is reported. The lesion was successfully removed with Nd-YAG laser photoresection.

An Er: YAG laser is a near infrared laser with a wavelength of 2.94m. This wavelength is identical to the peak wavelength of the light most readily absorbed by water. When used on living tissue with a sufficient water content, this laser causes a rapid evaporation of the water in just the most superficial layer of tissue, without greatly affecting the tissue in the neighboring area. The present...

Lasers represent a real quantum leap forward in the treatment of our patients, including the paediatric patient. The US Food and Drug Administration (FDA) gave approval for the use of the Er: YAG laser in 1997 for both hardand soft-tissue procedures. The erbium doped (erbium particles placed within the YAG crystal) crystal of Yttrium-AluminumGarnet’s (Er:YAG) development and success has made th...

We report a case of rapid progression of carcinoma of the penis, in a 90-year-old man, one year after yttrium-aluminum-garnet (YAG) laser therapy. This patient had received YAG laser ablation for well-differentiated, verrucous, squamous cell carcinoma of the penis at the age of 89, and was found on physical examination to have local recurrence. The recurrent tumors were surgically resected, and...
