Effect of individual structured and qualified feedback on improving clinical performance of dental students in clinical courses-randomised controlled study

Evaluation of anxiety-provoking situations related to clinical training in dental education

INTRODUCTION

The aims of this study were to evaluate the situations that cause anxiety in clinical training and to discuss the precautions that can be taken to reduce clinical anxiety in dental education.

MATERIALS AND METHODS

This multi-centred survey-based study was created through Google Docs, and 3rd, 4th and 5th grade dental students were included. The students were asked to rate their reactions on a 4-point Likert scale "not anxious" to "very anxious" for 27 questions related to academics, communication and interaction, diagnosis, dental treatments, deficiencies and mistakes in the treatments.

RESULTS

1332 students were reached, and 1320 students completed the questionnaire. Whilst extracting wrong tooth (3.53 ± 0.83), getting infected by patient (3.39 ± 0.85) and getting diagnosis wrong (3.31 ± 0.83) were identified as the 3 most anxiety-provoking situations, taking panoramic radiograph (1.48 ± 0.71) and communication with patients and dental assistants/nurses (1.76 ± 0.87; 1.64 ± 0.76) were identified as 3 situations that cause the least anxiety. Female students reported higher anxiety levels than male students in most of the questions (p < .05). A statistically significant difference was observed between the grades of the students (p < .05). 3^rd grade students showed statistically higher anxiety levels than higher grades in 16 out of 27 questions. No statistical significance was observed according to the status of the university (p > .05).

CONCLUSION

Questions related to diagnosis, delivery of the dental treatments, deficiencies and mistakes in the treatments caused higher anxiety levels amongst dentistry students. As experience and time in the clinical training increase, the anxiety level of the students decreases. Orientation programmes and establishing an effective communication between grades are recommended. Also, gender-based solutions must be taken into consideration.

Blended Learning on Blood Pressure Measurement: Investigating Two In-Class Strategies in a Flipped Classroom-Like Setting to Teach Pharmacy Students Blood Pressure Measurement Skills

For reliable blood pressure measurement, various potential sources of inaccuracies need to be considered to avoid incorrect decision-making. Pharmacy students should be sensitized and taught the skill accordingly. One strategy to teach students’ blood pressure measurement skills might be through a blended learning approach in a flipped classroom-like setting. With a randomized two-arm study among pharmacy students in their eighth semester, the required extent of in-class session in the scope of a blended learning approach in a flipped classroom-like setting was evaluated. Participants’ self-confidence and self-perceived proficiency were evaluated through a survey, and participants’ blood pressure measurement performance was assessed by objective structured clinical examination (OSCE). Participants’ satisfaction with, and perception of, the flipped classroom were also surveyed. The extended in-class activities did not result in a significantly higher increase of participants’ OSCE score and self-assessment score when compared to the brief in-class session. Both in-class sessions yielded a significant increase in the OSCE scores as well as in the self-assessment scores. Moreover, the teaching approaches were predominantly well-received by the students. The use of both flipped classroom-like approaches improved pharmacy students’ blood pressure measurement performance, though the brief in-class session was sufficient. Students’ self-confidence/self-perceived proficiency in blood pressure measurement skills increased similarly in both settings.

Comparison of different feedback modalities for the training of procedural skills in Oral and maxillofacial surgery: a blinded, randomized and controlled study

BACKGROUND

The feedback given to students plays an important role in their efficiency related to learning practical skills. In the present study, diverse feedback modalities have been investigated. Our hypothesis is that individualized and unsupervised video feedback can produce a similar learning experience as performing practical skills in an oral and maxillofacial surgery setting with conventional direct expert feedback (control group).

METHODS

This prospective, randomized, controlled, and blinded study compared direct expert feedback (DEF), individualized video feedback (IVF) and unsupervised video feedback (UVF). The participants were fourth-year dental students from University Goethe in Frankfurt. The students were assigned to one of the three feedback methods (n = 20 per group) using simple randomization. All participants watched an instruction video for an interdental ('Ernst') ligature and periphery venous catheterization. Next, the students were video recorded performing the tasks by themselves (pre-test). Following this, every student received feedback using one of the above-mentioned feedback modalities. The participants then performed the same task again while being video recorded (post-test) to measure the acquired competence. Six weeks later, the students participated in an objective structured clinical examination (OSCE) to evaluate their long-term knowledge retention. All examiners were blinded regarding the students' instructional approach and their affiliation in terms of the learning group.

RESULTS

For the interdental ligature, we found significant improvements in performance in each feedback modality group between the pre-test and post-test (p < 0.001). UVF had the strongest effect on performance time. The comparison between each group in the post-test showed no significant differences between the three groups.

CONCLUSION

This study showed that IVF and UVF can be considered an alternative or adjunct to conventional methods (i.e. DEF) when learning procedural skills in oral and maxillofacial surgery. However, DEF showed to be the most effective method of feedback and therefore preferable in teaching.

Self-Evaluation of Anxiety in Dental Students

Aim

The aim of the study was to analyze anxiety in female and male dental students related to their first procedure performed on a pediatric patient as part of their study curriculum.

Materials and Methods

The study was carried out in eighty-four 3rd year dental students (75.00% females and 25.00% males), aged 22-28 years. The participation in the research was anonymous and voluntary. The study was performed during clinical classes in pediatric dentistry where the students were supposed to perform simple prophylactic or therapeutic procedures on pediatric patients. To assess anxiety, a State-Trait Anxiety Inventory was used prepared by Spielberger et al. based on the American STAI questionnaire of 1970 that is composed of two-parts scales: the X-1 scale to assess anxiety as a state and the X-2 scale to assess anxiety as a trait. For statistical analysis, the Wilcoxon signed-rank test, Pearson's chi-squared test, and Mann-Whitney test as well as Statistica 10 programme were used.

Results

The results obtained from the first and second part of the questionnaire concerning anxiety as a state and as a trait showed high level of anxiety as a state in 51.19% of the students and as a trait in 32.14% and low level in 19.05% and 41.67%, respectively. The obtained results showed minimal and maximal values to be 24 and 71, respectively, for the STAI-1 scale (mean = 40.55), and 24 and 57, respectively, for the STAI-2 scale (mean = 41.75).

Conclusions

The results show that the anxiety level during clinical classes is relatively high in the studied population of students. Preparing the students to cope with stress resulting from treating the patients seems to be of importance. Such programmes should be implemented before the start of practical clinical classes. The acquired knowledge will be useful in further professional career.
