Lateral vs. Vertical: What Say You?

“Pure lateral or vertical compaction rarely occurs. The vectors of force applied during obturation techniques are an integrated blend of forces and result in composite of forces that are neither true vertical or lateral.” [Pathwyas of the Pulp-7th Ed.]

So, I guess we all pretty much use the same combined obturation technique. Downward force of finger-/hand-spreaders or pluggers and the resultant force moving the obturation material laterally. Some of you have asked me for a demonstration of my obturation technique:

After complete shaping and cleaning, I fit a sealer-coated master cone to 0.5-1mm short of the apex. I then use a heat source (Calamus Dual) and a series of 2-3 pluggers (S-Kondensers) to perform the down pack. Finally, I use the Calamus Dual again to back-fill to the level of canal orifice.

    Dr. E. Those are beautifull shapes. Can you describe or show how you achieve them?

      I start by creating a straight line access which for me it means opening the access cavity large enough to have all the canal orifices on the pulpal floor (not on the walls, creating a “mouse-hole” effect). I use mostly ProTaper and ProFile 0.04 ISO rotary files. I never use any file larger than an F2 in ProTaper series and as I continue with the apical enlaregment, I only use ProFile system (usually sizes 35 or 40/0.04 in MB’s and DB canals and 45 or larger in the P canals of the upper molars). I create and maintain a glide path throughout the entire procedure and use copious amount of irrigation solutions.

    Great work! I love the videos that you post.
