Investigation of surface roughness of composite fillings.

چکیده
Various grinders (diamond and carbide burs, and soflex disks) were used in polishing the composite filling surfaces. Polishing was carried out 10 minutes and 14 days after the material polymerization. The ground surface was then observed by a scanning electron microscope and the surface roughness expressed in [xm. Better surface polish and lower de gree of roughness were observed when polishing was performed 14 days after polymerization. Best results were obtained in specimens polished by soflex disks and diamond burs.

Investigation the Milling Strategies Effects on Machining of Convex Surfaces made of Glass/Epoxy Composite
In this study the effects of machining parameters such as shearing speed, feed rate, tool diameter and machining depth on different milling strategies i.e. 3D offset, spiral, raster and radial to produce the convex surface made of epoxy/glass composites is investigated. The effects of mentioned strategies on output parameters such as surface roughness and milling removal rate is also studied. T...
متن کاملComparative Evaluation of Surface Roughness of Three Different Composite Resins Following Polishing with a Two-Step Technique
Background and Aim: Nowadays, demand for same–color restorative materials, especially resin composites, is increasing. Access to the smooth surface with minimum level of surface roughness significantly results in more beauty, and the reduction of the accumulation of the plaque, gingival inflammation, and tooth discoloration. the aim of this study was surface roughness of three different composi...
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 کاملIn-vitro Comparison of the Impact of Four Types of Resin Composite on the Repaired Bond Strength and Surface Roughness After Sandblasting
Abstract Background and Aim: One of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. Since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. Considering the diverse composition of avail...
