Effects of Diode Laser Debonding of Ceramic Brackets on Enamel Surface and Pulpal Temperature.
AIM Debonding of ceramic brackets due to their high bond strength and low fracture toughness is one of the most challenging complications of orthodontic clinicians. Application of lasers might be effective in the debonding of ceramic brackets as they reduce bond strength of resins and, therefore, can eliminate the risk of enamel damage. However, the thermal effects of laser radiation on dental ...
متن کاملAssessment of enamel damage after removal of ceramic brackets.
INTRODUCTION Since the introduction of ceramic brackets, research has been performed to evaluate enamel damage caused during their removal. One problem in comparing treated and control groups is the absence of assurance that the surfaces were undamaged before the brackets were bonded and debonded, or that superficial treatment applied to the enamel could hinder damage detection. The aim of this...
متن کاملDebonding of ceramic brackets by Er:YAG laser
PURPOSE The objective of the present study is to evaluate the effects of Er:YAG laser debonding of ceramic brackets on the bond strength and the amount of adhesive resin remnant. MATERIALS AND METHODS Twenty human mandibular incisors were randomly divided into two groups of 10 and polycrystalline ceramic brackets (Transcend series 6000, 3M Unitek, Monrovia, CA, USA) were bonded on enamel surf...
متن کاملShear bond resistance and enamel surface comparison after the bonding and debonding of ceramic and metallic brackets
OBJECTIVE To evaluate, in vitro, the shear bond strength presented by three brands of polycrystalline ceramic brackets and one brand of metallic bracket; verify the adhesive remnant index (ARI) after the tests, and analyze, through scanning electron microscopy (SEM) the enamel surface topography after debonding, detecting the release of mineral particles. METHODS Sixty bovine lower incisors w...
متن کاملEnamel Surface Roughness after Debonding of Orthodontic Brackets and Various Clean-Up Techniques
OBJECTIVE This study aimed to evaluate enamel roughness after adhesive removal using different burs and an Er:YAG laser. MATERIALS AND METHODS The buccal surfaces of forty human premolars were sealed by two layers of nail varnish, except for a circular area of 3 mm in diameter on the middle third. The enamel surfaces were initially subjected to profilometry analysis and four parameters of sur...
