Abstract PDF PubReader ePub: Objectives
The present study aimed to evaluate the survival rate and clinical performance of class 1 composite restorations restored with the Filtek Bulk Fill composite material using either the bulk fill technique or the incremental technique at baseline (1 week) and at 3, 6 and 12 months of follow-up.
Materials and Methods
Forty-two patients with at least 2 carious teeth were selected. Following randomization, one tooth was restored with the Filtek Bulk Fill composite using the incremental fill technique, and the other tooth was restored with the same material using the bulk fill technique. Patients were recalled for follow-up at baseline (1 week) and 3, 6, and 12 months and evaluated using the FDI criteria.
Results
The data were analyzed using the McNemar χ² test. No statistically significant differences were found between the scores of teeth restored with either technique. At baseline and at 3, 6, and 12 months of follow-up; there were no significant difference in the clinical status of both groups of restorations.
Conclusions
Within the limitations of this study, using the bulk fill technique for restorations with the Filtek Bulk Fill material seems to be equally efficient to using the incremental fill technique.

The evaluation of color and color difference according to the layering placement of Incisal shade composites on the body composites of the indirect resin restoration: Su-Jung Park, Han-Young Lee, Myong-Yun Nah, Hoon-Sang Chang, Yun-Chan Hwang, Won-Mann Oh, In-Nam Hwang; J Korean Acad Conserv Dent 2011;36(1):37-49.

Abstract PDF PubReader ePub: Abstract Objectives:
The aim of this study was to evaluate the surface color of indirect resin restoration according to the layering placement of different shade of incisal composite.
Materials and Methods:
In this study, CIE L*a*b* value of 16 Body composite of Tescera ATL (Bisco, Schaumburg IL, USA) was measured by spectrophotometer (NF999, Nippon Denshuku, Japan), and compared to CIE L*a*b* value of Vitapan shade guide. Nine shade Incisal composite of Tescera ATL were buildup to 1 mm thickness on Body composites inlay block, and CIE L*a*b* value was measured. Incisal composite was ground to 0.5 mm thickness and CIE L*a*b* value was re-measured. Color difference between Body composite and Incisal composites layered on Body composite was calculated as a function of thickness.
Results:
Color difference between corresponding shade of Tescera Body composite and Vitapan shade guide was from 6.88 to 12.80.

L* and b*value was decreased as layering thickness of Incisal composite on Body composite was increased. But, a* value did not show specific change tendency.
Conclusions:
Surface color difference between Body composites and Incisal composites layered on Body composite was increased as the layering thickness of Incisal composite increased (p < 0.05).
