Micro-CT Evaluation of Four Root Canal Obturation Techniques

Figure 3

2D axial cross-sections and 3D reconstruction in the root canal filled teeth using different obturation techniques ((a–d) lateral condensation using 0.02 master cone; (e–h) lateral condensation using 0.04 master cone; (i–l) matched single-cone technique; (m–p) matched single cone-mediated ultrasonic activation). In the 3D figures, filling materials (gutta-percha/sealer) are in the orange color, and gaps/voids in the filling materials are in the yellow color.
