    Aim: The objective of this study was to identify the Er:CYSGG laser etching with and without sealant chlorhexidine is an alternative to acid etching by bonded ceramic bracket to enamel surface. Materials and Methods: 42 upper premolars were assigned into four groups; Acid etching +ceramic brackets (AC), Laser etching+ ceramic brackets (LC), LC-CHX (laser etching+chlorhexidine sealant) and AC-CHX (acid etching + chlorhexidine sealant). An Universal testing machine (H50KT machine) were tested SBSs (shear bond strength). Scores adhesive remnant index (ARI) was assessed by a stereomicroscope. Two other teeth were not bonded and were examined with a SEM (scanning electron microscopic). Results: Statistical analyses presented that SBSs of laser radiation were highly significantly difference than that of acid etching, als.. Read More»
