Stereomicroscope analysis of enamel surface after orthodontic bracket debonding.
After orthodontic brackets debonding, the remaining resin has to be removed. The purpose of this study was to determine the most efficient method as well as to introduce a new method of composite removal. The study was carried out on a sample of 30 premolars, extracted for orthodontic purposes. Brackets had been bonded using the Ortho One Bisco composite resin. After the removal of brackets, sa...
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...

متن کاملEnamel Surface Roughness after Orthodontic Bracket Debonding and Composite Resin Removal by Two Types of Burs
Objective: Increased enamel surface roughness following orthodontic bracket debonding leads to increased plaque accumulation and enamel decalcification. Therefore, different methods are employed to achieve smoother enamel surfaces after bracket debonding. This study compared enamel surface roughness following orthodontic bracket debonding and composite resin removal using white stone and tung...
متن کاملImpact of nanohydroxyapatite on enamel surface roughness and color change after orthodontic debonding
BACKGROUND The aim of this prospective in vitro study was to evaluate the effect of nanohydroxyapatite (nanoHAP) serum on the enamel surface roughness and tooth color stability after orthodontic debonding procedure. METHODS The crowns of 30 premolars were embedded in acrylic blocks with a 4 mm × 5-mm-sized window on the middle third of buccal surfaces. Primary roughness values were evaluated ...
