title: Clinical evaluation of a posterior resin composite: 3-year results.
abstract: OBJECTIVE
  To clinically evaluate a resin composite.
  
  
  METHODS
  Sixty restorations were inserted at a ratio of 1:3 in Class I and II preparations in molars. Caulk Prisma AP.H/Prisma Universal Bond resin composite restorative system was placed. All the restorations were evaluated using the USPHS system and M-L indirect scale; 6, 12, 24 and 36 month recalls were compared to baseline.
  
  
  RESULTS
  Color, interfacial staining, secondary caries, marginal integrity and surface texture (Alfa = 89%, 94%, 97%, and 100% respectively) were essentially unchanged from baseline for all restorations. One restoration failed due to secondary caries. Two were assessed with Charlie (C) ratings for marginal defects and one for wear. Direct wear analysis (Alfa = 12%) was significantly changed from the baseline. Indirect mean estimated wear measurements for each recall period, adjusted for baseline, were 21 +/- 18 microns, 54 +/- 29 microns, 67 +/- 29 microns, and 98 +/- 43 microns respectively. The wear of AP.H was characteristically linear (g2 = 0.987) for composites whose mean filler particle size approaches 1 micron or less.
