Purpose: This study aimed to assess the effect of a sequential augmented-reality tooth carving mobile application on the learning experience of users in practical training using tooth carving, focusing on maxillary central incisor carving.
Materials and Methods: The differences in the scores of tooth carving of maxillary central incisors between students taking a dental morphology course using the 2021 (existing two-dimensional practical training textbook) and 2022 (augmented-reality application) curriculums were analyzed. The scores were evaluated based on anatomical indicators, including mesiodistal and labiolingual length ratio, mesial and distal lengths, curvature of cervical line, inclination of axial plane, shape of mesial surface, shape of distal surface, shape of incisal edge, shape of cross-sections, and geometric shape scores of each surface. Mann-Whitney U test was used to evaluate the differences between the two groups in the SPSS statistical program.
Results: There was a difference in the tooth carving scores between the group that used the existing two-dimensional textbook and the group that used the augmented-reality tooth carving mobile application (P < 0.05). Moreover, significant differences were present in all subcategories (P < 0.05). The score of the group using augmented reality applications was higher than that of the traditional learning group.
Conclusion: This tooth carving augmented-reality mobile application can likely be utilized to guide learners through practical training involving maxillary central incisor tooth carving and help strengthen their competence. Further research is needed on the effect of augmented-reality mobile applications on learners, as well as on the evaluation of teeth other than the maxillary central incisors.
