I had to make the same decision--I was admitted to both schools as well. I ended up picking Maryland.
I believe that both schools will give you excellent clinical experience and make you into a great dentist. I felt that Maryland was in a safer neighborhood than Temple, and I liked that many students lived walking distance from campus (unlike Temple where they all seemed to talk about a ~30 minute commute). Plus, I mean, you saw Maryland's facility--amazing.
Do you happen to be from Pennsylvania or Maryland? The financial difference for in state vs out of state tuition could definitely bias your decision! I'm from Florida, so... I'm going to be super in debt no matter where I end up, so money wasn't a deciding factor for me.
Let me know what you decide on! 🙂
