Nice
Hello doctor, Can you please give me advise? A few days ago my upper molar was pulled out and near to this tooth I have a tooth with a zirconium crown. When I looked in mirror I found out that front part of this crown on side of my lips which used to be smooth now only has 1/3 of tooth smooth and seems like 2 millimeters thickness of my crown seems to be gone now. So I don't know what to do; is it possible to polish this crown to make smooth again? Or do I have to remove this crown? My tooth under this crown had a root canal and I hear that removing this crown is very difficult and can sometimes damage the tooth; is this correct?

Dear Dr,
Thank you very much for your interesting video. Pls help me: Which is better handpiece for this training (dental student): electric vs air-driven handpiece? Yours
We are using air driven handpieces for the dental students. Thanks for your comment!
@@UofUDentistryEducation Dear Dr.,
Thanks a lot your great info. It is very difficult for me to teach student how to control rpm using air-driven handpiece. So, we worry about their "cutting precision" and "quality of margin" in cavity preparation (preclinical training using typodont).
@@phanhung9622 We use an air-driven handpiece which helps the students, I feel, develop a better sense of handling and control. The electric handpiece has much greater torque and you can remove more tooth faster. I feel it is best for students to start with the air-driven.
@@UofUDentistryStudents Dear Prof. Thank you very much for your interesting procedure. May I have question: Do you evaluate under SEM (or others) to evaluate quality of final preparation by student using air-driven handpiece? Thanks
@@phanhung9622 The instructors are using their dental loops to evaluate the finished preparations.
