The smear layer should be removed at the end of instrumentation.

What is the concept of enlarging the coronal third of the root canal prior to working length determination?

Well-controlled diabetics are good candidates for endodontic treatment.

Should you obturate the canal when there is no more pain but the canal is still weeping?

Endodontic treatment of a mandibular central incisor is challenging because the most common variation is having two canals.

How many canals does a mandibular molar usually have

A dialysis patient is best treated the day after herodialysis because of:

The WL is 19 mm and the initial apical file is size 15. Using the rule of thumb that the MAF is 3 sizes bigger than the initial file, write below the size and length of the MAF

How does a tooth with irreversible pulpitis respond to percussion:

Pain in reversible pulpitis is immediate, momentary and quickly dissipates upon removal of the stimulus.

Employs the tip of the index finger or a cotton tip, with light pressure, to examine tissue consistency and pain response.
