Giving a lecture to dental residents

I received the following email ten minutes ago:

Hi Dr. (my last name),

 

Just wanted to confirm you will be giving a lecture to dental residents today 3:30-5pm room 309 Brauer Hall.  Topic is Pharmacology of IV Anesthetic Agents

 

thanks and see you at 3:30.

Hmm ..... strangely, this is not on my calendar. If I had agreed to give a lecture at the dental school I think I would have remembered. I also don't recall ever having earned a degree to be qualified to be addressed as "doctor." I am not sure if I will go or not. Maybe I will give the lecture and in return I will get a free dental check up.
