Patient John Allen is coming in for a root canal diagnosis on tooth #20. This is John's first time at an endodontist, and he describes pain when chewing and a constant dull pain for about a week.

1. What type of diagnostic testing will the dentist perform to determine the type of endodontic treatment required?
2. What tooth would be used as the control tooth during the diagnostic evaluation, and why is there a control tooth?
3. What type of pain control would the endodontist use during the procedure to help alleviate unwarranted stress and discomfort?
4. How would tooth #20 be completely restored, and which dentist would complete this procedure?

Diagnostic testing: The dentist will perform a combination of tests like percussion testing, palpation, thermal testing, and possibly use of an electric pulp tester or cold testing to evaluate the pulp's condition.

Control tooth: The control tooth typically used during diagnostic evaluation is the contralateral tooth (in this case, tooth #29) which is healthy for comparison and reference.

Pain control: The endodontist may use local anesthesia such as lidocaine to alleviate stress and discomfort during the root canal procedure.

Tooth restoration: Tooth #20 would be completely restored using a dental crown after the root canal treatment. A general dentist or prosthodontist would likely complete this restoration.
