Video Demonstration

Introduction: Demonstration of the access cavity preparation procedures to dental students is challenging due to the limited operating field and detailed nature of the procedures. It is especially difficult to visualize how instruments are functioning inside the pulp space. The aim of this study was to develop and compare two different views of video demonstration in teaching access cavity preparation. Materials and Methods: Two videos of access cavity preparation were filmed, showing occlusal view of a whole tooth (WT) and sagittal view of a sectioned tooth (ST). Using quasirandomization, third year dental students (n=57) were divided into two groups to watch either one of the videos. The perception and performance of both groups were compared using Mann-Whitney U test and Fisher exact test. Results: At baseline, group WT (n=29) and group ST (n=28) were not significantly different in terms of operative scores (p=0.330). After watching the videos, the basic understanding of the theories were similar between both groups. However, ST responded more positively towards the helpfulness of the video in visualizing the inner anatomy of the tooth and in implementing the procedures (p<0.05). ST also completed the exercise within a shorter time (p<0.001). Nevertheless, the quality of the prepared access cavities was not significantly different between groups. Conclusion(s): Using sagittal view of sectioned tooth in video demonstration of access cavity preparation can improve students learning and performance speed. We highly recommend showing the sagittal view of sectioned tooth in video demonstration of access cavity preparation.

Crucial Assumption

Reports of experiences of ownership over a fake hand following simple multisensory stimulation (the ‘rubber hand illusion’) have generated an expansive literature. Because such reports might reflect suggestion effects, demand characteristics are routinely controlled for by contrasting agreement ratings for ‘illusion’ and ‘control’ conditions. However, these methods have never been validated, and recent evidence that response to imaginative suggestion (‘phenomenological control’) predicts illusion report prompts reconsideration of their efficacy. A crucial assumption of the standard approach is that demand characteristics are matched across conditions. Here, a quasi-experiment design was employed to test demand characteristics in rubber hand illusion reports. Participants were provided with information about the rubber hand illusion procedure (text description and video demonstration) and recorded expectancies for standard ‘illusion’ and ‘control’ statements. Expectancies for control and illusion statements in synchronous and asynchronous conditions were found to differ similarly to published illusion reports. Therefore, rubber hand illusion control methods which have been in use for 22 years are not fit for purpose. Because demand characteristics have not been controlled in illusion report in existing studies, the illusion may be, partially or entirely, a suggestion effect. Methods to develop robust controls are proposed. That confounding demand characteristics have been overlooked for decades may be attributable to a lack of awareness that demand characteristics can drive experience in psychological science.

Mesh Technique

Abstract Development of retro muscular space with transversus abdominis release has reached maturity in endoscopic surgery. Next-level reconstruction is adaptation to parastomal hernia repair alone or in conjunction with another abdominal wall hernia repair. We aim to present this extraperitoneal modified mesh technique based on the Sugarbaker principle with video demonstration and share clinical data and results from twenty-four patients operated with this technique within two years from the spring of 2019 to the spring of 2021. 77% patients had para-colostomy hernia and 41% of the patients had accessory repairs for midline or opposite flank hernia. 18% had prophylactic mesh at index operation, 27% were recurrent parastomal hernia and ostomies were formed median 32 months prior to parastomal hernia repair. 72% of the patients were operated robotically and 28% laparoscopically. Median follow up at time for presentation will be 17 months.
