Online Assessment Platforms: What is on Offer?

Web-based digital assessment platforms offer several benefits for educational providers. The aims of this study were to evaluate digital assessment platforms suitable for design, delivery and quality assurance of assessments in dental education to facilitate informed choices by educational providers. The study was based on an online cross-sectional survey. A questionnaire was designed to include relevant details of providers, types of assessments offered, post-assessment psychometrics, remote proctoring, integration with digital learning platforms faculty training, and indicative costs of services. Following a google search, 25 potential providers of digital assessment software were identified and contacted by email. Ten companies responded to the questionnaire. All providers, except one, reported extensive experience in delivering high-stake assessments for programs in dentistry, medicine and allied health professions. All companies confirmed availability of a wide variety of assessment formats and also offer remote proctoring either directly or through third parties. Indicative costs of different assessment platforms were also provided. This paper underscores the need for dental institutions to make informed decisions when choosing the most appropriate digital assessment platforms to suit their educational needs. It also provides a snapshot of services offered by commercial providers of assessment platforms. The Association for Dental Education in Europe can serve as a central hub to guide dental institutions on making informed choices for suitable assessment platforms to address their needs

ChatGPT-A double-edged sword for healthcare education? Implications for assessments of dental students

Introduction: Open-source generative artificial intelligence (AI) applications are fast-transforming access to information and allow students to prepare assignments and offer quite accurate responses to a wide range of exam questions which are routinely used in assessments of students across the board including undergraduate dental students. This study aims to evaluate the performance of Chat Generative Pre-trained Transformer (ChatGPT), a generative AI-based application, on a wide range of assessments used in contemporary healthcare education and discusses the implications for undergraduate dental education. Materials and Methods: This was an exploratory study investigating the accuracy of ChatGPT to attempt a range of recognised assessments in healthcare education curricula. A total of 50 independent items encompassing 50 different learning outcomes (n = 10 per item) were developed by the research team. These included 10 separate items based on each of the five commonly used question formats including multiple-choice questions (MCQs); short-answer questions (SAQs); short essay questions (SEQs); single true/false questions; and fill in the blanks items. Chat GPT was used to attempt each of these 50 questions. In addition, ChatGPT was used to generate reflective reports based on multisource feedback; research methodology; and critical appraisal of the literature. Results: ChatGPT application provided accurate responses to majority of knowledge-based assessments based on MCQs, SAQs, SEQs, true/false and fill in the blanks items. However, it was only able to answer text-based questions and did not allow processing of questions based on images. Responses generated to written assignments were also satisfactory apart from those for critical appraisal of literature. Word count was the key limitation observed in outputs generated by the free version of ChatGPT. Conclusion: Notwithstanding their current limitations, generative AI-based applications have the potential to revolutionise virtual learning. Instead of treating it as a threat, healthcare educators need to adapt teaching and assessments in medical and dental education to the benefits of the learners while mitigating against dishonest use of AI-based technology

Effectiveness and Student Perceptions of Haptic Virtual Reality Simulation Training as an Instructional Tool in Pre-Clinical Paediatric Dentistry: A Pilot Pedagogical Study

Simulation training for invasive dental procedures is a core component of the pre-clinical dental curriculum. Besides conventional mannequin-based simulators, dental schools are now incorporating haptic virtual reality simulation (HVRS) devices to facilitate the transition of students from the simulated dental learning environment to the clinical settings. This study aimed to assess student performance and perceptions of HVRS training as a pedagogical tool in pre-clinical paediatric dentistry. After practicing the primary molar pulpotomy procedure on plastic teeth, participants were randomized into test and control groups. Test group students performed the same procedure on a HVRS device, namely the SIMtoCARE Dente®. Subsequently, both the test and control group students attended another conventional pulpotomy simulation session where the quality of their access outline and pulp chamber deroofing steps were evaluated on plastic teeth. After the control group students also experienced the HVRS, all study participants completed a perception questionnaire on their experience. No significant differences were found between the study and control group students for the quantitative parameters assessed. Although the students regarded HVRS to be a useful adjunct to support their pre-clinical training, an overwhelming majority of the students did not consider HVRS to be a replacement for conventional pre-clinical simulation training

The use of aesthetic paediatric full coverage restorations among paediatric dental practitioners: an international survey

Despite the recent growing evidence in support of prefabricated zirconia crown use as a successful option in managing grossly carious anterior and posterior primary teeth, the use of such crowns remains controversial within the paediatric dental profession. This study aims to assess the use of aesthetic full coverage paediatric restorations among paediatric dentists worldwide, with emphasis on aesthetic prefabricated zirconia crowns. This was an online cross-sectional survey questionnaire study comprising of 38 multiple-choice questions disseminated worldwide through the contact lists of national, regional and international paediatric dental organisations and social media platforms. The survey was completed by 556 respondents thus achieving power, with 391 (70.3%) females and 165 (29.7%) males. The respondents were from 55 different countries spread across six continents. The use of aesthetic full coverage restorations was reported by 80% (n = 444) of the respondents. For restoring anterior teeth, participants mainly used either composite strip crowns (94.4%, n = 419) or zirconia crowns (73.6%, n = 327), while those who used aesthetic crowns for restoring posterior teeth mainly used zirconia crowns (68.2%, n = 303). Within the limitations of this study, the results have shown a wide use of full coverage aesthetic restorations, including the use of zirconia crowns, of primary teeth within this international sample of practicing dentists.Scopu

A Diagnostic Accuracy Study of Laser Doppler Flowmetry for the Assessment of Pulpal Status in Children's Permanent Incisor Teeth

Introduction: The aim of this study was to assess whether laser Doppler flowmetry is more accurate than the conventional pulp sensibility tests (electric pulp test and ethyl chloride) in assessing the pulpal status of permanent anterior teeth in children and to identify the laser Doppler flowmetry’s Flux cut-off threshold. Methods: A cross-sectional diagnostic accuracy study with randomization was performed and included 74 participants (8- to 16-year-old children). Participants had 1 maxillary central or lateral incisor with either a completed root canal treatment or an extirpated pulp and a contralateral tooth with vital pulp. Outcome measures included the sensitivity, specificity, and predictive values as well as the repeatability of all tests. Results: A significant difference between the Flux values for teeth with vital and non-vital pulps was found. The cut-off ratio for laser Doppler flowmetry was 0.6, yielding a sensitivity of 53% and a specificity of 33%, which were lower than the values of the electric pulp test (sensitivity = 83.8%–94.6% and specificity = 89.2%–97.6%) and ethyl chloride (sensitivity = 81.1%–91.9% and specificity = 73%–81.1%). The repeatability of laser Doppler flowmetry, electric pulp testing, and ethyl chloride were 0.85, 0.86, and 0.81, respectively. Conclusions: Laser Doppler flowmetry was unable to differentiate between teeth with vital and non-vital pulps. The results of this study showed that there was a high probability for false results. Further development of laser Doppler flowmetry in assessing pulpal blood flow would be required before it could be recommended for clinical use, especially in children

Effect of dental trauma management resources on dental practitioners' confidence and knowledge: A pilot cross-sectional study

Background/Aim: The knowledge of standardized care guidelines is critical to the confidence of practitioners in managing dental trauma. Therefore, the aim of this study was to assess the awareness, use and impact of the International Association of Dental Traumatology guidelines, and the online Dental Trauma Guide on general dental practitioners' self-reported confidence and knowledge in managing traumatic dental injuries in the primary and permanent dentitions. Materials and Methods: A cross-sectional, pre-piloted, 27-item self-administered questionnaire survey was distributed electronically to general dental practitioners' working within five member states of the Gulf Cooperation Council countries (Kingdom of Bahrain, Kingdom of Saudi Arabia, Kuwait, Oman, and Qatar) between September and December 2020. Data were collected and analysed using descriptive statistics and Wilcoxon Signed Rank test analysis for relevant comparisons. Results: A total of 294 respondents completed the survey, with the majority being from the Kingdom of Saudi Arabia (47.4%) and Qatar (27.3%). A lack of evidence-based knowledge in managing traumatic dental injuries was evident among more than half of the respondents. Respondents who were cognizant of the recent International Association of Dental Traumatology guidelines (2020) and those who use the Dental Trauma Guide routinely demonstrated a higher self-reported confidence level in managing both simple and complex primary dentition trauma, as well as simple traumatic dental injuries in the permanent dentition (p <.05). Conclusion: This survey highlights critical deficiencies in the knowledge of a large number of the respondents in the management of dental trauma which is likely to cause irreversible long-term patient effects.Open Access funding provided by the Qatar National Library

Use of the Hall technique by specialist paediatric dentists: a global perspective.

Background The Hall technique (HT) is popular with UK paediatric dentists (PDs). Global PDs perception/use of HT is unknown.Aim To investigate global PDs opinions/use of HT.Materials and methods A cross-sectional questionnaire of 26 questions was sent to specialist PDs across the globe.Results Responses of 709 PDs from six continents were obtained. The majority (n = 654, 92.32%) had heard about HT but only 50.6% (n = 358) used it, with wide country variations. Respectively, 37.5%, 31.5% and 31% were neutral, against or supportive of HT when they initially heard about it. Only 17% of HT users said it was always the treatment of choice for non-pulpal asymptomatic carious primary molars (NPACPMs), 62% would take a pre-operative radiograph, 65% would consider using high speed drills before HT, 63% would never consider HT under general anaesthesia, 56% would use HT under N2O sedation. Finally, in a clinical scenario of a NPACPM in a cooperative 6-year-old, 75% of PDs would choose conventional restorative methods over the HT.Conclusion The HT is recognised, but not used, by an outright majority of PDs across the globe. Identifiable barriers such as lack of training, perception as substandard dentistry and perceived lack of evidence reduced its use

Alternatives to root canal treatment: Tooth autotransplantation

Although endodontic treatment is successful in most instances, some severely compromised teeth cannot be maintained in the long term. In children and adolescents, dental trauma can sometimes result in such severe damage to the tooth and supporting structures that tooth loss becomes inevitable. Also, a realistic long-term assessment of the prognosis of root canal treatment is required to be made when this treatment is carried out in a young patient, especially when the treated tooth has incomplete root development and a compromised crown/root ratio. Root fractures are often the medium term outcome of such root canal treated teeth. It is imperative that clinicians involved in the care of children with such injuries and faced with these clinical dilemmas undertake an interdisciplinary planning approach, which would give the patient a sustainable, biological long-term functional and aesthetic outcome. Autotransplantation is one such approach that should be considered to replace young permanent teeth where the long-term prognosis of endodontic management is not considered favourable. This chapter covers the rationale, indications, step-by-step treatment approach, and interdisciplinary planning that is required for a successful outcome of autotransplantation
