Sridhara KS, Mankar S, Jayshankar CM, Vinaya K - J Pharm Bioallied Sci (2014)

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: Results showed that the RDIZ (hybrid layer) at the coronal, middle, and apical areas formed by All-Bond 2 with C and B resin cement were denser when compared with the Panavia F bonding system and Panavia F resin cement [Table 1 and Graph 1].
