The natural teeth group (NTG) included the teeth used by the class of 2021, and the artificial teeth group (ATG) assessed the artificial teeth (LikeReal, Porto Alegre, Brazil) used by the class of 2022. The teeth were visually and radiographically observed, and the errors were divided according to the location in the crown or in the root. Errors in the crown included perforation, damage to the marginal ridge, fracture, and remnants of gutta-percha. Errors in the roots included overfilling, obturation at the apex, obturation > 2 mm short of the apex, voids, instrument separation, ledge, and root fracture.
