“…Tooth morphology is the study of the anatomy and morphology of permanent and deciduous teeth (Obrez et al, ), and is usually taught in the initial years of dental courses (Kilistoff et al, ; McHanwell, ). Dental surgery students, as well as dental hygienists, technicians and nurses, study detailed tooth morphology as it aids in recreating lost tooth structure for clinical work and also assists in dental laboratory work (Abu Eid et al, ; de Azevedo et al, ; Bakr et al, ). Furthermore, knowledge of anatomical features of the teeth also helps understanding their normal anatomy and interactions, as well as identifying developmental anomalies and pathologies (Obrez et al, ; Bakr et al, ).…”

Tooth morphology has a pivotal role in the dental curriculum and provides one of the important foundations of clinical practice. To supplement tooth morphology teaching a three‐dimensional (3D) quiz application (app) was developed. The 3D resource enables students to study tooth morphology actively by selecting teeth from an interactive quiz, modify their viewpoint and level of zoom. Additionally, students are able to rotate the tooth to obtain a 3D spatial understanding of the different surfaces of the tooth. A cross‐over study was designed to allow comparison of students’ results after studying with the new application or traditionally with extracted/model teeth. Data show that the app provides an efficient learning tool and that students’ scores improve with usage (18% increase over three weeks, P < 0.001). Data also show that student assessment scores were correlated with scores obtained while using the app but were not influenced by the teaching modality initially accessed (r2 = 0.175, P < 0.01). Comparison of the 2016 and 2017 class performance shows that the class that had access to the app performed significantly better on their final tooth morphology assessment (68.0% ±15.0 vs. 75.3% ±13.4, P < 0.01). Furthermore, students reported that the 3D application was intuitive, provided useful feedback, presented the key features of the teeth, and assisted in learning tooth morphology. The 3D tooth morphology app thus provides students with a useful adjunct teaching tool for learning dental anatomy. Anat Sci Educ 00: 000–000. © 2018 American Association of Anatomists.

“…Therefore, good knowledge of dental anatomy is paramount in clinical practice (McHanwell, ). To restore the aesthetics of the smile, the professional must possess technical‐scientific knowledge about the current composites, artistic sense, dexterity, and manual ability (Rubinstein and Nidetz, ; de Azevedo Rde et al, ; Patil et al, ; Bakr et al, ). Without this knowledge, it is not possible to practice dentistry, which aids in restoring damaged or lost teeth and dental function.…”

“…In addition to scientific knowledge, the student must possess an ability to develop the manual skills necessary for the practical application of this knowledge (McHarg and Kay, ; Eid et al, ). There is a wide variety of teaching techniques that any teacher can adapt to his/her teaching style, the characteristics of the students, and the classroom (Eid et al, ; de Azevedo Rde et al, ; Magne, ; Bakr et al, ).…”

Knowledge of dental anatomy is of great importance in the practice of dentistry, especially in oral rehabilitation, because without this knowledge, professional practice is not possible. Dental carving plays a major role in training dental students as it develops their manual dexterity. This randomized controlled trial aimed to evaluate the influence of didactic-theoretical reinforcement on the theoretical and practical knowledge of dental anatomy of preclinical students by examining the quality of the anatomical restorations performed by these students before and after a didactic-theoretical reinforcement. For the evaluation of theoretical knowledge, a questionnaire with closed questions about dental anatomy was used. To evaluate the effect of didactic reinforcement on dental carvings, two groups of 15 preclinical students were assessed. Experimental group (G1) received a three-hour theoretical tutoring on dental anatomy, while the control group (G2) did not. The dental carving scores obtained by the two different groups were compared using Student's t-test. Cohen's d was used to estimate the effect sizes between groups. The frequency of correct answers given for each theoretical knowledge question was compared in each group using Fisher's exact test. T-test was also used to compare the means of the two groups' final scores of theoretical evaluations. To compare these final scores obtained in both carving and theoretical tests, a principal component analysis was performed with different items assessed in each test to obtain factor loading scores and a final weighted score, where factor loadings were considered for each item. Weighted scores were compared using t-test. Also, scores obtained during the head and neck course were assessed and compared using t-test. Spearman's correlation test was used to assess the correlation between scores obtained prior to the anatomy course and scores obtained in the dental carving exercise. The theoretical evaluation revealed no significant difference between the grades (mean ± SD) of G1 (85.1 ± 6.6%) and G2 (86.2 ± 9.1%) with the grades of a baseline test that was previously obtained when students submitted to the study (P = 0.725). Regarding the tooth carving assessment, the dental carving quality by students of G1 has significantly improved, except for tooth #23 (P = 0.096). Theoretical reinforcement of dental anatomy seems to improve the students' carving performance but does not enhance their knowledge about dental anatomy.

“…Previous studies have claimed that the main advantages of digital resources include unrestricted access to information regardless of place and time, thus allowing exible study time. 23,24 Interestingly, the average score of dental gypsum sculpture improved signi cantly (by 4.39 points) for students who matriculated in 2016, but the mean theoretical assessment score was no different than that for students who matriculated in 2014. Similar to our results, Alzahrani et al 25 revealed that dental carving scores were higher for students of the experimental group taught by new methods, but the mean theoretical knowledge scores did not improve signi cantly compared with those for the traditional lecture group.…”

Background: The tooth morphology course is an important basic dental course. However, it is difficult to fully reflect the three-dimensional (3D) morphological characteristics of tooth structure in two-dimensional pictures in traditional textbooks. The aim of this study was to assess the effect of 3D-printed plastic model teeth in the teaching of tooth morphology. Methods: Twenty-two undergraduate students who matriculated at the School of Stomatology, the Fourth Medical University, in 2014 and 23 who matriculated in 2016 participated in the study. Each student who matriculated in 2016 was given a full set of fourteen standard 3D-printed plastic model teeth for use during the learning process, and an anonymous questionnaire was used to evaluate the usefulness of the 3D-printed plastic model teeth from the perspective of the students. Results: There was no significant difference between the two groups in the scores of the theoretical examination or the total score. However, for the score of the sculpted gypsum teeth, the students who used the 3D-printed plastic model teeth in their studies scored significantly higher (P=0.002). More than 90% of the students thought that the 3D-printed plastic model teeth were of great help or were very helpful for mastering the anatomy of teeth and for carving the gypsum teeth. Conclusion: Standard 3D-printed plastic teeth can effectively assist students in learning tooth morphology by transforming two-dimensional pictures and descriptions in the textbook into a 3D conformation, effectively promoting students' learning and mastery of tooth morphology and structure. Additionally, the results suggest that 3D-printed plastic model teeth are of great help to the students in mastering and improving their carving skills.
