J.R. DUNN, C.A. MUNOZ, R. KINZER, D. TAN, J. SY, and A. WILSON, Loma Linda University, CA, USA

Objective: This Clinical Trial evaluated the clinical performance of a new polychromatic high density composite resin (Esthet.X., L.D. Caulk) over a two year period.  Methods: Forty-three anterior and posterior restorations were placed in 27 subjects (25 at 2 Years). Following cavity preparation the teeth were etched, restored, and polished following manufacturer's instructions.  Marginal adaptation (MA), Anatomic Form (AF), color match (CM), secondary caries (SC) marginal discoloration (MD) and polishability (PO) were evaluated.  At two years, using a modified USPHS grading systems the following results were found in percentages (%) (BL=Base Line): Results:
MA AF CM SC MD PO

Alpha 54 64 84 88 53 52 100 100 100 96 47 100

Delta 0 0 0 0 0 0 0 0 0 0 0 0
Conclusions: At the 2-year recall:  1) categories AF, CM and SC were unchanged from baseline; 2) MA showed a decrease in restoration quality, 3) PO showed increase in the surface polish over time, and 4) Overall clinical performance is acceptable for routine clinical use.
