What are the technological requirements for online dental education?

Okay, so I’m a professor at a dental school and we’re looking into expanding our program to include more online learning, maybe even a fully online option down the line. But honestly, I’m a bit clueless when it comes to the tech side of things. It’s not just about Zoom lectures, is it?

What kind of platforms are best suited for delivering dental curriculum? I’m thinking about things like interactive anatomy modules, simulations for procedures (like fillings or extractions), and even ways for students to practice diagnosing from radiographic images.

What kind of hardware and software are absolutely essential for students to have? Are we talking high-end computers with specific graphics cards? Should we provide them with tablets pre-loaded with relevant apps? And what about internet bandwidth – what’s the minimum acceptable speed for things to actually work smoothly?

Also, what about faculty training? We’ve got some professors who are digitally savvy, and others who… well, let’s just say they struggle with email. What kind of resources are available to help us train our faculty in using these new technologies effectively? We need to make sure they’re comfortable and confident delivering instruction online.

And finally, what about security? We’re dealing with sensitive patient data (even in simulated scenarios), so how do we ensure that all of this is secure and HIPAA compliant? What kind of encryption and security protocols do we need to have in place? We don’t want any data breaches!
