We will compare the biological relationship between endodontics and periodontics with cases shown, explaining how to differentiate the diagnoses, and how to treat these conditions. Understand when and how to save these teeth and the use of diagnostic tools like the CBCT as well as their limitations to give your patients the most accurate prognosis for treatment.
