I actually found that sdn was a good resource for this. In fact, if you search in google: “the school you’re interviewing at + Questions + interview + sdn dental” you’ll get actual questions from previous interviewees. Here’s an example: University of Maryland School of Dentistry
Additionally, search for things like “most common interview questions + sdn dental” to get an idea of the questions any school may ask, such as “why this school?” or “why dentistry?” The way I prepared is: I made answers to all of these. I opened a word doc and wrote them down. Answers should only be 1-3 thoughts/sentences long imo, but you should be able to expand on your thoughts if asked a follow up question. Don’t memorize answers word for word, but rather use the doc as a reminder of what you might say to a specific question, kind of like note cards when making a presentation.
