Brief Summary:
Evaluation of Resin Composite Posterior Restorations Using Modeling Resin Insertion Technique versus Conventional Composite Placement Technique in Class I Lesions Randomized Clinical Trial
Detailed Description:
Statement of the problem In a restorative procedure an important objective is to obtain restorations with smooth surfaces Surface roughness has a major influence on plaque accumulation secondary caries and gingival irritation Further it may directly influence wear behavior and the marginal integrity of composite restorations A roughened surface of a resin composite restoration is also likely to be stained by exogenous sources such as coffee tea or red wine leading to the discoloration of the material
One of the main drawbacks of sculpting composite restorations is that some materials are sticky reducing the ease of handling and insertion of the material into the tooth cavity Some materials readily adhere to the composite instruments thus limiting reestablishment of the shape and anatomical contour of the tooth As a result the application of lubricants on the composite instrument such as modeling liquidsresins between the layers of composite have been proposed
Rationale Modeling resins can be directly applied between the layers using a brush or can be used as a lubricant on manual instruments In both the aforementioned techniques the ease of instrumentation during the placement of esthetic restorations is superior compared to the traditional restorative techniques Moreover any pores or gaps on the surface of the composite placed by means of the layering technique can be easily resolved Hence the modeling resin facilitates the reduction of defects in the body of the restoration and aids in improving the mechanical properties
Although these methods are widely used a potential shortcoming is that these techniques may adversely affect the physical and surface properties of the resin composite However it is unknown whether different compositions of adhesives or modeling agents may affect the surface microhardness surface roughness and color stability of composites over time
