Students' appraisal of a preparedness model for the provision of oral health care during a pandemic.

BACKGROUND: The COVID-19 pandemic has impacted the provision of oral health care worldwide, prompting the discussion of preparedness. This study aimed to perform an initial appraisal of the usability, spatial representation, and clarity of a newly developed preparedness model from the perspective of senior undergraduate dental students at the University of British Columbia, Vancouver, Canada, enrolled in the 2020-21 academic year. Answers were analyzed thematically via an inductive coding process between March and June 2021. RESULTS: All the 111 students in years 3 (#55) and 4 (#56) appraised the preparedness model, generating more than 200 pages of text. Four main themes were identified across the essays: streamlined depiction, information-based approach, adaptability to an ever-changing situation, and room for improvement. Although the majority of students appraised the model as being useful in fostering information-seeking behaviour, few students disagreed with the model's portrayal and made further suggestions. CONCLUSIONS: Preparedness models can better guide oral health care providers during a health crisis such as a pandemic. The recently developed preparedness model was appraised as useful by senior undergraduate dental students, although alternative portrayals of the model were suggested. A comprehensive assessment of the newly developed model (and of its variations) is warranted to better support oral health care service delivery during a pandemic.

The structural and functional connectivity neural underpinnings of body image.

How we perceive our bodies is fundamental to our self-consciousness and our experience in the world. There are two types of interrelated internal body representations-a subjective experience of the position of a limb in space (body schema) and the subjective experience of the shape and size of the limb (body image). Body schema has been extensively studied, but there is no evidence of the brain structure and network dynamics underpinning body image. Here, we provide the first evidence for the extrastriate body area (EBA), a multisensory brain area, as the structural and functional neural substrate for body shape and size. We performed a multisensory finger-stretch illusion that elongated the index finger. EBA volume and functional connectivity to the posterior parietal cortex are both related to the participants' susceptibility to the illusion. Taken together, these data suggest that EBA structure and connectivity encode body representation and body perception disturbances.
