Energy-dispersive X-ray Spectroscopy Analysis of Erbium, Chromium:Yttrium-scandium-gallium-garnet-treated Enamel Surfaces: An Study.

Aim And Objective: The present study evaluated the effects of erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser on the weight percentage of mineral content of enamel when etched at three different power settings.

Materials And Methods: Total 20 extracted molar teeth were taken as samples. Enamel slabs were prepared by sectioning the crown from the buccal and lingual aspect with a double-sided diamond disk at slow speed.

Comparative evaluation of microleakage after root-end resection by erbium, chromium: Yttrium-scandium-gallium-garnet (Er, Cr:YSGG) laser and carbide bur with or without placement of mineral trioxide aggregate: An study.

Background: Root-end resection followed by retrofilling is one of the prime requisites to avoid apical microleakage.

Aim: It comparatively evaluated the microleakage after root-end resection by erbium, chromium:yttrium, scandium, gallium, and garnet laser and carbide bur with or without placement of mineral trioxide aggregate (MTA).

Materials And Methods: In this study, 60 maxillary central incisors were decoronated and biomechanically prepared.

Comparative Evaluation of the Etching Pattern of Er,Cr:YSGG & Acid Etching on Extracted Human Teeth-An ESEM Analysis.

Introduction: Etching of enamel and dentin surfaces increases the surface area of the substrate for better bonding of the tooth colored restorative materials. Acid etching is the most commonly used method. Recently, hard tissue lasers have been used for this purpose.
