OBJECTIVE THE AIM WAS TO EVALUATE THE EFFECT OF ER, CR: YSGG laser and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on surface micro-hardness of primary tooth enamel. MATERIALS AND METHODS A total of 30 freshly extracted caries free primary anterior teeth were cleaned and stored in 1% thymol. Teeth were embedded in acrylic resin such that only their buccal surfaces were exposed...

The objective of this literature review was to critically review the evidence available in the literature regarding the expediency of erbium family of lasers for root bio modification as a part of periodontal therapy. The literature search was performed on the Pubmed using MeSH words such as "lasers/therapeutic use, scaling, dental calculus, tooth root/anatomy and histology, ultrasonic therapy"...

background and aims. a proper bond must be created between the existing composite resin and the new one for successful repair. the aim of this study was to compare the effect of three mechanical surface treatments, using diamond bur, air abrasion, and er,cr:ysgg laser, on the repair bond strength of the silorane-based composite resin. materials and methods. sixty cylindrical composite resin spe...

NTRODUCTION In the past 100 years there has been extensive development of the mechanical cutting devices used in dentistry. However, while considerable progress has been made in this area of mechanical cutting, dental patients are still afraid of the noise and vibration produced by the mechanical action of the air turbine or ultrasonic scalers. From the end of the 20th century until now, there ...

BACKGROUND The erbium:yttrium scandium gallium garnet (Er:YSGG) laser differs from other laser techniques by having a faster and higher cure rate. Since the Er:YSGG laser causes an appropriate proportion of ablation and coagulation, it has advantages over the conventional carbon dioxide (CO2) laser and the erbium-doped yttrium aluminum garnet (Er:YAG) laser, including heating tendencies and exp...

Background: Acne scar is the most common complication in acne that occurs about 49% of individuals. Fractional resurfacing lasers such as CO2 laser and erbium-doped yttrium aluminum garnet (Er: YAG) have been widely used for treatment give satisfying results complications pain, hyperpigmentation, infection, prolonged erythema, scarring. erbium: scandium gallium YSGG) solves previous techniques'...
