Bottom Line: The results were statistical analyzed.Microscopic examination of Group 1 showed significantly higher percentage of RDIZ (P < 0.05) than Group 2.All-Bond 2 showed denser and wider RDIZ compared with the Panavia F.

ABSTRACT

Aims and objectives: The aim of this study is to compare and evaluate the thickness of resin dentin interface zones (RDIZ) obtained by luting carbon fiber post to intra-radicular dentin, either with All-Bond 2 bonding agent and C and B composite cement or Panavia F dentin-bonding system and Panavia F resin cement.

Materials and methods: Twenty single rooted mandibular premolars of similar sizes were prepared for the carbon fiber post after biomechanical preparation and obturation. They were divided into two groups, Group 1 and 2 of 10 samples each. Carbon fiber posts used for Group 1 samples were luted using All-Bond 2 and C and B cement. For Group 2 carbon fiber posts were luted using Panavia F dentin-bonding system and Panavia F resin cement. All the 20 samples were sectioned longitudinally and marked at three points on the length of the tooth from the dentin-core interface to the apex at 2 mm, 5 mm, and 8 mm to get coronal, middle, and apical areas, respectively. The formation and thickness (width) of the RDIZ at the marked areas was evaluated by scanning electron microscope using ×1000 magnification. The results were statistical analyzed.

Results: Irrespective of the adhesive systems used all specimens showed a RDIZ formation. Microscopic examination of Group 1 showed significantly higher percentage of RDIZ (P < 0.05) than Group 2. RDIZ morphology was easily detectable at coronal and middle areas of all specimens.

Conclusion: All-Bond 2 showed denser and wider RDIZ compared with the Panavia F.

Mentions: The sectioned surface of the sample was etched with 10% phosphoric acid for 15 s, washed for 30 s with tap water and then deproteinized for 30 s with 2% sodium hypochlorite. Each section was mounted on aluminum stubs and sputter coated with gold as shown in Figure 1. The formation and thickness (width) of the RDIZ or hybrid layer of the dentin-bonding systems were evaluated at the previously marked areas by scanning electron microscope using ×1000 magnification as shown in Figures 2 and 3. The results obtained were subjected to statistical analysis.
