through the use of a 3D image, however, it is overkill to take a CBCT just to check

obturation. Thirty years ago, Boston University grad students were taught to use paper
point tests (see “Warm Vertical Obturation Technique” and/or “Summary of Schilderian

Techniques”) to determine the fWL. To this date, the author still checks the wet-dry

intersected point and adjusts the master cone accordingly prior to down-pack.
Additionally, a radiograph should be taken after the plugger has reached the targeted

depth (5-7mm from fWL) to determine if more down-packing is required, or if one can

proceed to back-filling. If a post is to be placed in the canal, only down-packing of the
GP is required to ensure a tight apical seal at the fWL without any need for back-fill

afterwards.

Dr. Schilder’s Remark:

Time in endodontics is the biggest enemy.
