Introducing a novel educational training programme in dental implantology for pregraduate dental students

INTRODUCTION

This study aimed to determine whether implant surgery procedures can be implemented in the dental curriculum by designing novel courses for students. Additionally, this study assesses the perception of these courses and how they can be established in the future.

MATERIALS AND METHODS

Students from the third to fifth years participated in a programme consisting of 4 modules according to their academic year. The modules taught theoretical and practical content as well as clinical references. After participating, the students completed two questionnaires with research questions (RQ1 = evaluation of the relevance and effects; RQ2 = impact of modules 3 and 4) to evaluate the programme. The questionnaires consisted of 52 statements, each rated on a 6-point scale (1 'totally disagree' to 6 'totally agree'). Cronbach's alpha analysis was used, and median values, interquartile ranges and Pearson correlations (p-value) were statistically calculated.

RESULTS

In total, 94 students completed the questionnaires. Cronbach's alpha exceeded 0.7 for all constructs except for one (skills training). The highest evaluated median was 6, and the lowest was 4.75. Pearson correlations were significant (<0.05) for perceived importance/lectures, perceived importance/tutor performance, lectures/skills training, skills training/tutor performance and tutor performance/lectures. Seventeen analysed free comments expressed strong interest in implantology courses for the curriculum. 88% of the students wished for more practical exercises in dental implantology during the curriculum or suggested expanding the programme in the future.

CONCLUSION

The programme was highly accepted among dental students. The students wished for more practice in the future to perform supervised procedures on patients.

INTRODUCTION

Following worldwide progress in digital technology, the utilization of advanced technology to update the concept and mode of education has become an important way to improve the quality and scale of talent training. Adoption of virtual reality technology has a positive effect on dental education. Virtual reality technology has been introduced into Chinese dental education nearly 10 years ago, and a holistic teaching system that employs virtual simulation technology to assist instructors in teaching and students in learning has gradually been formed.

MATERIALS AND METHODS

Based on the work of the West China School of Stomatology, Sichuan University, we introduced the necessity and advantages of the application of virtual simulation technology in talent training in dentistry and the status of this teaching system.

RESULTS

A virtual dental simulation teaching system was constructed and applied in China. Virtual reality technology was incorporated into the four elements of the teaching system. This reformed system carried out educational informatization in terms of the construction of a virtual simulation teaching platform, development of virtual simulation teaching resources, improvement of the student training model, and upgrading of teaching management.

CONCLUSION

The holistic teaching system implemented at the West China School of Stomatology, Sichuan University, highlights the successful incorporation of virtual reality technology into various aspects of dental education. The construction of this system reflects the deep integration of modern information technology and dental education, with the aim of helping dental educators promote teaching methods and management model in the future.

Evaluating the effect of digital technology on the learning of orthodontic cephalometric measurement

Background: This study aimed to evaluate the effectiveness of integrating digital technology into cephalometric measurement teaching. Methods: In total, 94 undergraduates of stomatology were recruited and randomly allocated to two groups. According to the cross-over design, both groups completed cephalometric measurements by the traditional hand-drawn method and digital technology (the Dolphin software) in different order. In the traditional hand-drawn method, students depicted the outline of the craniofacial anatomical structures on sulfuric transfer paper first, then marked the measurement points and completed the measurement of line spacings and angles; by digital technology, they marked the points in the software and adjust the automatically generated outlines of the structures to obtain the results. Two professional orthodontists were invited as instructors and their measurements were set as standards. An online questionnaire was also used to investigate students' attitudes toward digital technology being used in the cephalometric teaching process. Results: There were significant differences of students' measurements ( P 1-SNA<0.01, P 1-SNB=0.01 and P 1-L1-NB (mm)<0.01; SNA: sella-nasion-subspinale angle, SNB: sella-nasion-supramental angle, L1-NB (mm): the distance from the lower central incisor tip to the nasion-supramental plane) between the traditional method and digital technology. Besides, the results of most items by digital technology were closer to the standards than those by the traditional method, including five items with statistical significance ( P 2-SNB<0.05, P 2-L1-NB (mm)<0.01, P 2-FMA<0.05, P 2-FMIA<0.05, P 2-IMPA<0.01), while three items were the opposite ( P 2-SNA<0.05, P 2-ANB (mm)<0.01, P 2-NA-PA<0.01). The questionnaire showed more students preferred digital technology (33%) as a better teaching method than the traditional method (2%) and 72% of participants thought they had mastered 50-80% of cephalometric knowledge after the course. Conclusions: This study demonstrated effectiveness and acceptance of the course applying digital technology during the cephalometric teaching process.

Experience and perceptions of nigerian undergraduate dental students to virtual learning during the COVID-19 pandemic

Background

COVID-19 outbreak impacted negatively on teaching globally with traditional face-to-face teaching mostly affected.

Aim

This study evaluated the experiences and perceptions of Nigerian undergraduate dental students to virtual learning (VL) including perceived institutional challenges during the COVID-19 pandemic.

Subjects and Methods

This was a cross-sectional survey of 346 dental students from all 13 Nigerian dental schools. Data collection was done using an open/close-ended online questionnaire.

Results

The level of awareness and understanding of dental students to virtual learning was high (93.6%) and good (84.7%), respectively. About two-thirds (62.4%) of the students had a virtual learning classroom experience before the COVID-19 pandemic. Clinical students spent more time on the Internet and reported more confidence in the use of VL platforms than their pre-clinical counterparts during the lockdown (p < 0.05). More male students than their female counterparts felt that VL had less quality than traditional classroom teaching (p < 0.05). Similarly, male students showed more confidence in the use of VL online tools (p < 0.05). Institutional and self-perceived preparedness to VL was ranked low and moderate by the students, respectively. The high cost of data subscriptions, unstable Internet connectivity, and lack of other institutional facilities were perceived as challenges to effective VL by students. None of the identified variables predict effective VL.

Conclusions

Experiences of dental students and their preparedness to VL were moderate. The high cost of Internet subscriptions, unstable Internet connectivity, and low institutional facilities were major challenges to students' VL. None of the socio-demographic factors could successfully predict effective VL.

Evaluation on a teaching software for removable partial denture framework design

BACKGROUND

Removable partial dentures (RPDs) are widely used as a dental prosthesis and have a wide application scope.

OBJECTIVE

To explore the effect of using design software in the preclinical teaching of removable partial dentures (RPDs).

METHODS

Unreal Engine software was used to build the RPD framework design teaching and training software. All 131 undergraduate students majoring in stomatology in the class of 2018, Kunming Medical University, were randomly divided into three groups and received either traditional experiment teaching, flipped classroom teaching, or software teaching for RPD design. The application effect of the software in the preclinical teaching of RPD design was evaluated by analyzing the examination results and through the use of a questionnaire survey.

RESULTS

The differences in the theoretical examination scores among the traditional teaching group, the flipped classroom group, and the software teaching group were not statistically significant (P> 0.05), while the average design scores of upper Kennedy Class I and lower Kennedy Class II subclass II in the software teaching group were significantly higher than those in the traditional teaching group (P< 0.05). Overall, 75% of the students in the software teaching group reported that this teaching method could improve their learning initiative, a higher percentage than in the traditional teaching group (55.8%, P< 0.05). Meanwhile, 90.9% of the students in the software teaching group reported that the software could make RPD-related theoretical knowledge more visual and intuitive, and 93.2% of these students felt it was helpful for understanding the RPD three-dimensional (3D) spatial structure. These percentages were higher than those in the traditional teaching and flipped classroom groups (P< 0.05).

CONCLUSION

In the preclinical teaching of RPD design, software training helped the students better understand the 3D structure of RPDs and establish clear design ideas, and it may also be valuable for in-depth research and promotion purposes.

A Cross-Sectional Questionnaire-Based Survey on Blood-Borne Infection Control among Romanian Dental Students

Background and Objectives: According to the CDC estimates, 5.6 million healthcare workers worldwide are exposed to the risk of occupationally contracting blood-borne pathogens, including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and others. The aim of the present study was to assess the knowledge level on blood-borne infection control (IC) among Romanian undergraduate dental students. Materials and Methods: A cross-sectional, questionnaire-based survey with 21 items was conducted from May 2022 to June 2022. The study had α = 0.620 and Cronbach’s Alpha = 0.660. The Chi-square test was used for data comparison. The data were analyzed using IBM SPSS version 26 (IBM, Armonk, NY, USA), and p ≤ 0.05 was considered statistically significant. Results: The study sample included 207 subjects with a mean age of 21.38 (±1.9) years, 59.9% F (female), 40.1% M (male), 38.2% students from year II and 61.8% from year III. Most of the subjects did not have knowledge on the indirect mode of IC, the persistence of HBV, HCV, or HIV, or the existence of rapid tests (p < 0.05). PEP (post-exposure prophylaxis) was known as follows: HBV, 32.36% (67); HCV, 25.60% (53); and HIV, 36.71% (76); p < 0.05. Only 50.24% (104) had knowledge on the recommended testing moments (p = 0.019 by gender, p = 0.752 by year of study). The optimal time to access PEP was considered by 28.01% (58), p ˃ 0.05. Only 37.68% (78) strongly agreed that the one-hand covering technique of the needle was efficient in IC (p < 0.05). Conclusions: The evaluation of the knowledge regarding IC highlighted major gaps in the perception of the subjects, which underlined the need to implement sustained forms of continuing medical education on this topic.

Survey of student attitudes toward digital technology in practical technical dental education using the AR-Demonstrator-App

PURPOSE/OBJECTIVES

More and more creative applications are used in the field of dentistry for clinical practice, patient orientation, teaching, and learning, in order to awake the students' interest and to enable a deep learning and its retention. The aim of this study was to demonstrate the impact and the effectiveness of the current simulation laboratories on the practical dental education. For this purpose, a survey on a new developed "AR-Demonstrator-App" was conducted during the orthodontic technical courses in 2017, 2018, and 2020 in the Department of Orthodontics (C.G. Carus, TU Dresden, Germany).

METHODS

With this application, the students had the opportunity to see every single step with instructions on how to manufacture a removable orthodontic device in a compulsory technical course. At the end of these courses, the students were asked to anonymously fill out a printed questionnaire with 12 questions regarding the learning progress related to the app.

RESULTS

The yearly mean Likert scores and their bootstrapped 95% confidence intervals as well as the yearly median Likert scores suggest a very positive feedback about the use of the new application as an educational instrument. Despite the recognized predominant benefits of this app, the students concluded that they do not prefer the total replacement of the physical plaster casts and that a combination of conventional and computer-based education provided the optimum approach to acquisition of dental practical skills.

CONCLUSIONS

This survey indicates a generally positive attitude toward computer-assisted simulation systems, providing the facility for acquisition of knowledge and practical skills in a multimedia environment.

Curriculum setting and students' feedback of pre-clinical training in different dental schools in China-A national-wide survey

INTRODUCTION

Adequate time and effective training facilities are essential for undergraduate dental students participating in pre-clinical dental practice to ensure them providing safe treatment for patients in the future. The study aimed to explore the current status of pre-clinical dental training in China in relation to the curriculum setting and students' feedback of pre-clinical training in different dental schools and thus provide information for further standardise curricula.

MATERIALS AND METHOD

An online questionnaire was distributed electronically to undergraduates in 44 Chinese dental schools of different levels according to China Discipline Ranking (CDR). The questionnaire collected information in relation to the training hour and student to facility ratio of four main dental courses (cariology and endodontics, periodontology, prosthodontics and oral surgery), as well as the application and effect of virtual reality (VR) simulator in pre-clinical dental practice in different schools. Students' feedback was also collected.

RESULTS

A total of 565 valid questionnaires were recruited. Results of this cross-sectional survey show that training hour of periodontology course was the lowest, and oral surgery course showed most prominent shortage of facilities. The application of VR simulator amongst schools is uneven. Students from A and A+ level schools showed higher satisfaction with their pre-clinical courses and reported a more positive attitude towards the use of VR simulator than other students. (p < .05).

CONCLUSION

Pre-clinical dental training in China remained imperfect in insufficient training time, training facility and students did not have access to standard pre-clinical training and quality assurance. VR technique has potential values in pre-clinical dental practice in China.

Digital Undergraduate Education in Dentistry: A Systematic Review

The aim of this systematic review was to investigate current penetration and educational quality enhancements from digitalization in the dental curriculum. Using a modified PICO strategy, the literature was searched using PubMed supplemented with a manual search to identify English-language articles published between 1994 and 2020 that reported the use of digital techniques in dental education. A total of 211 articles were identified by electronic search, of which 55 articles were selected for inclusion and supplemented with 27 additional publications retrieved by manual search, resulting in 82 studies that were included in the review. Publications were categorized into five areas of digital dental education: Web-based knowledge transfer and e-learning, digital surface mapping, dental simulator motor skills (including intraoral optical scanning), digital radiography, and surveys related to the penetration and acceptance of digital education. This review demonstrates that digitalization offers great potential to revolutionize dental education to help prepare future dentists for their daily practice. More interactive and intuitive e-learning possibilities will arise to stimulate an enjoyable and meaningful educational experience with 24/7 facilities. Augmented and virtual reality technology will likely play a dominant role in the future of dental education.

SIGNIFICANCE

With disruptions intrinsic in digital dentistry's new state of the art, patient experience has improved. More restoration options are available delivering longer lifetimes, and better esthetics. Fresh approaches are bringing greater efficiency and accuracy, capitalizing on the interest, capabilities, and skills of those involved. New ways for effective and efficient inter-professional and clinician-patient interactions have evolved. Data can be more efficiently mined for forensic and epidemiological uses. Students have fresh ways of learning. New, often unexpected, partnerships have formed bringing further disruption - and novel advantages. Yes, digital dentistry has been disruptive, but the abundance of positive outcomes argues strongly that it has not been destructive.

Evaluation of the Knowledge and Attitudes of Dental Students toward Occupational Blood Exposure Accidents at the End of the Dental Training Program

Aims and Objectives:

This study was conducted to assess knowledge, attitudes, and behavior regarding occupational blood exposure accidents (OBEA) among dental students at the end of the whole dental education program.

Materials and Methods:

The survey was performed using a student self-administered questionnaire during July 2015 in the dental teaching hospital in Rabat. It was conducted on 117 dental students registered in the 5^th year. The results were analyzed by SPSS Software, Version 13.0. Univariate analysis was performed by descriptive statistics, and bivariate analysis was used to identify correlations between different variables.

Results:

Eighty-three students answered the questionnaire (participation rate: 70%). Most participants had incomplete knowledge about the management and the risks of OBEA. Thirty-five participants (42%) experienced at least one occupational exposure to patients' blood. Needle recapping has been the main cause of such injuries (41%). Most accidents occurred, respectively, in the oral surgery (51%) and the restorative dentistry (17%) departments. According to many participants, they had received insufficient education concerning this topic.

Conclusions:

More effective education on prevention and management of OBEA is highly recommended to reduce the prevalence of such injuries. Dental schools should set up a local management unit for following and supporting the exposed students.
