OBJECTIVES OF FINISHING & POLISHING

·         Adequate adaptation
·         Continuity of the restoration margins with the tooth.
·         Optimum restoration contour
·         Proper occlusal contact
·         Surface free of any scratches /irregularities, to make it biologically acceptable
A restoration that is well finished & polished promotes oral health especially at the gingival margins by preventing the accumulation of food debris &pathogenic bacteria, thereby minimizing gingival inflammation, secondary caries, & periodontal destruction. A rough surface contains microscopic pits in which food particles lodge &encourage galvanic action, which leads to tarnish & corrosion. A surface becomes reflective only when the surface imperfections are below 1mm, as this is below the resolution of wavelength of light.
