Impact of the Haptic Virtual Reality Simulator on Dental Students’ Psychomotor Skills in Preclinical Operative Dentistry

One of the current trends in dental education is to empower dental students on a global platform using advanced technology. Haptic virtual reality simulation (HVRS) is a relatively new technology in the field of teaching and learning operative dentistry. This study aims to assess the impact of haptic virtual reality simulation (HVRS) on dental students’ psychomotor skills acquisition in preclinical operative dentistry. Class I cavity preparations (CP) were performed at baseline by 21 novice dental students on plastic teeth. Duration of CP was recorded and cavity features were evaluated and scored. Then, students were exposed to HVRS training on CP. Another Class I CP was performed by each student on plastic teeth after HVRS training, then evaluated, and the duration was recorded. There was a statistically significant decrease in CP performance time after HVRS training (p < 0.001) and an increase in the mean total marks of CP after HVRS training (p < 0.001). The change in the students’ performance in the CP displayed a statistically significant improvement after HVRS training in smoothness of the pulpal floor (p = 0.047), pulpal floor direction (p = 0.029), buccal, lingual, and mesial wall direction (p = 0.004, p = 0.025, p = 0.002), mesial and distal wall smoothness (p = 0.01, p = 0.001), internal line angle (p = 0.024), and internal point angle (p = 0.029). Overall improved performance in psychomotor skills was found after HVRS training. It could be beneficial to incorporate HVRS training early in pre-clinical operative dentistry courses as an adjunct to conventional phantom head training.

Dental Students’ Didactic and Psychomotor Skills Performance in Dental Anatomy and Preclinical Operative Dentistry Courses in a Saudi Governmental School

Background. Knowledge and psychomotor skills are essential in dental education. The aims were to (1) investigate the correlation between dental students’ didactic and psychomotor skills performance in the dental anatomy and preclinical operative dentistry courses and (2) explore the impact of gender on students’ performance in both courses. Materials and Methods. A retrospective cohort study was performed on dental students’ (164 students; 72 males and 92 females) dental anatomy and preclinical operative courses scores of the same class over 2 years (2018–2020). Didactic and practical scores were collected. The didactic scores included examinations. Practical scores included tooth wax carving for the dental anatomy course and class II cavity preparations and restorations for the preclinical operative. Student’s t-test and ANOVA were used to analyze the difference between the didactic and psychomotor skills scores of both courses and genders. Pearson’s correlation coefficient was used to explore correlations ( p < 0.05 ). Results. Moderate, positive, and significant correlations were found between didactic scores in both courses and between dental anatomy’s didactic and psychomotor skills. A weak, positive, and significant correlation existed between the preclinical operative didactic and psychomotor silks ( p < 0.05 ). Females’ didactic performance was significantly better than males. Gender had a significant, positive, and moderate correlation in the dental anatomy course, but moderate-weak in preclinical operative ( p < 0.05 ). Conclusion. Students’ didactic and psychomotor performance correlations in dental anatomy and preclinical operative courses were positive. The correlation was moderate and weak and varied by course. Gender had a significant impact on student performance and varied by procedure and courses investigated.

Association of Class Attendance and Test with Grades Attained in BDS Final Professional

OBJECTIVES: The purpose of this study was to verify the association of class attendance percentage, and regular test marks of each taught subject in BDS final year with marks obtained in final examination. METHODOLOGY: Class attendance and test performance records of all participants were obtained from the college authority, and the final professional examination marks sheet issued by UHS was obtained from the college office. Potential confounders like age, gender and parents’ occupation were also recorded for each student. Pearson’s correlation coefficient test was applied to verify the association of class attendance and class tests marks percentage for different subjects taught with final marks. Multivariate analysis was undertaken by adjusting for confounders in the model. RESULTS: This study found significant correlation between each taught subject class test marks with final marks obtained in each respective subject of the final year. Class attendance of each taught subject had weak, insignificant association with final marks except in one subject i.e., Operative Dentistry. CONCLUSION: Class test marks are a stronger predictor of final examination marks than class attendance percentage.

A MOVE STRUCTURE MODEL FOR DENTISTRY RESEARCH ARTICLE ABSTRACTS: A GENRE-BASED STUDY OF VARIATIONS AND SIMILARITIES IN EIGHT DENTISTRY SUBDISCIPLINES

The abstract is one of the most important sections in a research article (RA) because it is the first section researchers read to determine whether it is relevant to their research. The abstract provides an overview or summary of the entire article. In the dentistry discipline, the RA abstract can either be structured using headings or written as a summary. However, subdisciplinary investigations of intradisciplinary (within the same discipline) variations of move structures in dentistry RA abstracts are lacking. This study aimed to investigate the prototypical rhetorical move structure realizations of 119 English RA abstracts in eight dentistry disciplines: Oral Sciences, Periodontics, Restorative Dentistry, Endodontics, Operative Dentistry, Prosthodontics, Oral and Maxillofacial Surgery, and Orthodontics. It also aimed to investigate whether there are any intradisciplinary variations and/or similarities between the eight dentistry subdisciplines in terms of move sequence and length. The findings showed a lack of intradisciplinary variations in the rhetorical four-move structure (Purpose-Method-Result-Conclusion) across the eight dentistry subdisciplines. The Introduction/Background move was not present in all the dentistry subdisciplines; therefore, it is optional in five subdisciplines but conventional in the Oral Sciences, Endodontics, and Oral and Maxillofacial Surgery subdisciplines since its occurrence exceeded 60 per cent of investigated RA abstracts of those subdisciplines. The analysis of the move lengths indicated the importance of the Methods and the Results moves in dental research discourse because each move constituted over 25 per cent of text space. The findings revealed the importance of drawing learners’ attention to the research gap when establishing the context for a study. Future studies may employ the proposed move-analysis model for RA abstract analyses in other academic disciplines.

Is the number of procedures completed a valid indicator of final year student competency in operative dentistry?

Introduction Concerns regarding the preparedness of dental graduates often focus on the number of procedures undertaken before qualification.Aims To assess the validity of numerical requirements in determining whether a student has sufficient competency to graduate.Materials and methods In total, 50,821 observations of student activity while on the restorative clinic, for two integrated student cohorts (n = 139), were continuously recorded using the LiftUpp system from their third year to graduation. Analysis of data determined the most frequent type, location and difficulty of the direct restorations provided.Results Four groups of students, categorised by the total number of restorations they provided, were identified. Those with the most restorations (70+) had a statistically significantly greater experience in restoring different tooth surfaces, in different quadrants, on different patients than those with the least (40-49). However, increased numbers did not correlate with increasing difficulty, suggesting that students simply became more adept at easier procedures.Discussion Using a derived measure of 'consistency', it was observed that increased performance consistency was not correlated with greater overall experience. Furthermore, only 4% of students were 100% consistent in their performance in their final year.Conclusions These data suggest that a 'numerical requirements' approach cannot be used, in isolation, as a valid measure of the competency of an individual. Further work is needed to validate consistency as a holistic measurement to characterise the performance of graduates.

The Status of Theme in Research Article Abstracts in Seven Dentistry Subdisciplines: A Text-Based Study of Intradisciplinary Variations and Similarities in Thematic Choices and Thematic Progression Patterns

A research article (RA) abstract provides an overview or summary of the whole research. It is one of the most important sections in an RA since it is the first section researchers read to decide if the article is relevant to their research or not. Researchers need to know the intradisciplinary (within the same discipline) variations and similarities in the choice of Theme and thematic progression (TP) patterns in RA abstracts in their discipline. Several studies have investigated variations and similarities in the use of Theme across disciplines. To the best of our knowledge, there is a lack of studies investigating intradisciplinary variations in the use of Theme in RA abstracts of dentistry subdisciplines. As epistemological differences exist between the various dentistry subdisciplines, it is pertinent to examine if there are intradisciplinary variations in the construction of Theme in the subfields of dentistry. The present study aims to investigate if there are any intradisciplinary variations and similarities in the use of Theme and TP patterns across seven dentistry subdisciplines: oral sciences, periodontics, endodontics, operative dentistry, prosthodontics, oral and maxillofacial surgery, and orthodontics. The study is framed by Halliday’s systemic functional linguistics’ approach to language and Daneš’s model for TP patterns. The findings revealed intradisciplinary significant differences between the subfields of dentistry in terms of the use of Theme types at p < .05 (p-value=0.0294), while there were no significant differences in the use of TP patterns and thematic markedness. Various interesting linguistic features characterizing the subdisciplines were found, although no significant interdisciplinary differences were found between dentistry RA abstracts and the findings reported in the literature of other disciplines. Finally, implications for novice dental researchers attempting to write an RA abstract are presented.
