The Tubular Penetration Depth and Adaption of Four Sealers: A Scanning Electron Microscopic Study

Figure 2

The tubular penetration depth of sealers. Many gaps could be found between the Cortisomol and the canna walls (Figures 2(a1) and 2(a2)). iRoot SP was cylinder-shaped and partially homogenous. There were some gaps between iRoot SP and dentinal tubules walls (Figures 2(b1) and 2(b2)). AH-Plus was spherical and homogenous. There was a good connection between the fillings and dentine tubules and little gaps were in existence (Figures 2(c1) and 2(c2)). RealSeal SE was cylinder-shaped and most homogeneous. It had a tight junction with tubules walls and no obvious gaps were observed (Figures 2(d1) and 2(d2)). The red arrows indicate the area that was zoomed in.
