Assessment of undergraduate students in tooth extraction competence- A cohort study

Assessing competency in exodontia: A UK perspective

INTRODUCTION

Assessment ensures that undergraduate students and postgraduate trainees are providing optimal patient care. Numerous assessment methods are currently being used within the United Kingdom. Therefore, the purpose of this review was to provide an overview of the methods used to assess competency in exodontia and compare methods against criteria defined for good assessment.

MATERIALS AND METHODS

A systematic narrative review was carried out. Databases were electronically searched for published studies assessing the competence of undergraduate students and postgraduate trainees in exodontia up to October 2023.The validity, reproducibility, equivalence, feasibility, educational impact, catalytic effect and acceptability of each assessment method was considered.

RESULTS

In this review, 591 undergraduate students (n = 529) and postgraduate dental trainees (n = 62) had their competence in exodontia assessed. Undergraduate students were assessed on simple exodontia with forceps and elevators, whereas postgraduate trainees were assessed on the surgical removal of mandibular third molars. Only one study took place in a simulated dental environment, the remaining (n = 7) took place in a clinical environment. A range of formative and summative assessment methods were identified including structured clinical objective tests (SCOT), self-assessment, peer assessment and logbooks. Common marking criteria such as global rating and checklist scales were also highlighted.

CONCLUSION

This review highlights the lack of evidence to support one form of assessment and the lack of consensus on assessment within the United Kingdom. Further research related to this topic, alongside the opinion of trainees and trainers is required to improve assessments. This will maximise learning opportunities for trainees and translate to better patient care.

Self-perceived preparedness of new dental graduates from a Middle Eastern university

INTRODUCTION

Preparedness for independent clinical practice is a core goal of undergraduate dental education. The aim of this study was to evaluate the self-reported preparedness for the dental practice among new dental graduates from a University in the Middle East.

METHODS

Following ethics approval, a purposive sampling techniques were used to invite newly qualified dental graduates at a Middle Eastern University. A validated research instrument, namely the Dental Undergraduate Preparedness Assessment Scale (DU-PAS), was used to evaluate the self-perceived preparedness of the participants. Data collection was undertaken online using Google Forms and data were analysed to compute the descriptive statistics, reliability and demographic differences among the participants.

RESULTS

A total of 82 participants provided their response yielding a response rate of 68%. The participants included 49 males and 33 females. The overall reliability of DU-PAS was excellent. (α = 0.93). The participants included less than 40% of participants were able independently to prescribe medications, assess orthodontics needs and perform endodontic treatment on multirooted teeth. In addition, more than 65% indicated low confidence in evaluating new dental materials and products, interpreting new research findings and behavioural management of children.

CONCLUSION

The present findings identified strengths and weaknesses of new dental graduates from a Middle Eastern university. The participants were confident in basic clinical skills but lower confidence was reported for complex dental procedures. The findings highlight the learning needs of new dental graduates and can serve to inform the undergraduate curriculum to enhance the preparedness of future cohorts of dental graduates.

Radiographic Evaluation Factors That Influence the Decision of the Tooth Extraction Method

INTRODUCTION

A simple tooth extraction method usually involves using elevators and forceps to remove the tooth easily. In contrast, a surgical extraction method requires utilizing a straight handpiece to facilitate the tooth extraction, either removing bone or sectioning the tooth into pieces.

OBJECTIVE

In this research, we aim to diagnose a tooth radiographically before extraction and determine certain factors to observe which extraction method might be more feasible, either simple or surgical.

METHODOLOGY

This study followed a retrospective cross-sectional study design. The x-ray radiographs (periapical (PA) or panoramic) were collected from the R4 system in the university dental hospital for data collection. Different radiographic influencing factors were measured, such as bone density, bone level, endodontic involvement (RCT/post and core), crowned or remaining root, and root morphology. Statistical associations were performed using SPSS (IBM Corp., Armonk, NY) with a one-way ANOVA test.

RESULTS

There were 62 cases with 47 simple and 15 surgical extractions. There was a non-significant (p>0.05) association between the measured factors and the extraction method, either simple or surgical tooth extraction. Although bone density measurements showed a slight tendency toward PA lesions and simple tooth extraction.

CONCLUSION

There was no significant association between the factors and extraction methods. Future research is required to determine whether or not preoperative radiographic evaluation can influence the decision for the tooth extraction method.

Perceived confidence of dental students and new graduates in performing tooth extractions-An exploratory study

INTRODUCTION

The ability to perform uncomplicated tooth extractions is a core clinical skill in undergraduate dental education. The aim of this study was to evaluate pre-extraction assessment skills of dental students and interns and explore their self-perceived confidence in performing these tooth extractions.

MATERIALS AND METHODS

A cross-sectional survey investigated the self-perceived confidence to perform the extraction for a set of eight expert-rated cases. The participants were dental students at three different stages, that is, in Years 4 and 5 of the Bachelor of Dental Surgery (BDS) programme and interns. The participants were asked to rate the difficulty level of each of the eight tooth extraction cases. The self-perceived confidence of the participants to perform extraction of each was also explored. Finally, the participants were asked to identify the main reason for the perceived lack of confidence.

RESULTS

A total of 199 responded to the survey, yielding a response rate of 94.7%. The effect of grade of extraction (the expert rating of cases) and stage of education on difficulty ratings was assessed using a mixed three stage of education × 4-grade ANOVA, with response (Difficult = 1, Easy = 0) as the dependent variable. The results showed that there was a correlation between the stage of education and grade of extraction and affected the self-perceived confidence of the participants. Gender showed a significant impact with females categorizing significantly more cases as difficult. A three-way contingency table (counts of each confidence-level response by stage of education by expert rating of cases) suggests a statistically significant association between the three factors. Most participants identified limited clinical exposure as the main reason for their perceived lack of confidence.

CONCLUSION

The findings of this study show that a majority of the participants were able to recognize tooth extraction cases which were beyond the scope of their training stage with females reporting a lower confidence. Increased clinical exposure to a wider range of tooth extraction cases with varying levels of difficulty may contribute to improving the self-confidence of undergraduate dental students and interns.

Clinical experience improves academic outcomes in dental Oral surgery education

INTRODUCTION

This paper aimed to determine if the level of a dental student's clinical experience in oral surgery influences the student's oral surgery academic outcomes.

MATERIALS AND METHODS

The oral surgery clinical activity and academic outcomes for all students who completed their dental training in 2017, 2018, 2019 and 2020 from the University of Sydney were analysed for correlation.

RESULTS

The clinical activity performed by 313 students was recorded. There was a weak, but statistically significant, Pearson correlation between total dental extractions and academic outcomes (r = .243, p = <.001). The total number of dental extractions performed was the only statistically significant variable on academic outcomes with linear regression analysis (β = .227, p = .005; model R2  = .077). The increase of a student's clinical experience from less than 45 to more than 65 dental extractions raised their oral surgery academic results by an average of 6.4%. There were no academic benefits to earlier clinical experience.

CONCLUSION

An increase in experience with dental extractions resulted in an increase in oral surgery academic outcomes, plateauing at 65 dental extractions. There was no academic advantage to dental student's having earlier clinical experience.

An Educational Evaluation of Thiel Cadavers as a Model for Teaching Suturing Skills to Dental Students during the COVID-19 Pandemic

Suturing is an essential skill in dentistry and not one easily acquired. The COVID-19 pandemic prompted a change to the use of Thiel cadavers and online resources with the aim of improving skill acquisition using the best model available. This study investigated the utility of the Thiel cadaver for teaching suturing skills and the potential impact of the lockdown. Fifty-seven year 4 students attended a teaching session. Student views on this teaching were explored via a questionnaire survey and qualitative data collected from a focus group. Data were analysed using an inductive approach. The response rate was 53% (30 students) for the questionnaire with 9 students participating in the focus group. Independent feedback was provided by two members of the teaching staff. Online video resources were very well received by the students with 97% agreeing that it was useful preparation. Ninety percent (90%) thought that the cadaveric model was suitable for this teaching and realistic. Positive emergent themes from the focus group centred on the use of the cadaveric model and the positive and relaxed teaching and learning environment. Staff perceived this model as superior to previously used models. There were no reported negative pandemic impacts and the cadaver model was well received.
