Figure 2: An image showing the apical, middle, and coronal sections of a tooth obturated by (a) single-cone technique (in the apical and middle images, well-obturated canals with no significant voids are seen, whereas in the coronal image, a void is seen between the gutta-percha cone and the sealer), (b) thermoplasticized technique (in the apical image, a void is seen in between the gutta-percha and the sealer; in the middle image, a void is seen in between the gutta-percha itself; and in the coronal image, no voids are detected)
