(k) An animation image illustrates PTG F2 blades cutting a perfect F2 radicular preparation shape. ![]() (j) Dentin-loaded PTG F2 apical flutes prove the apical shaping is complete. If apical blades are nude of dentin shavings, this is a cue to progress to the next larger size (PTG F2) in order to confirm the apical shape. (i) The PTG F1 is used in a follow/brush motion to length. The PTG S1 and PTG S2 are used in a Brush/Follow sequence to length. ![]() (h) The PTG S2 carves away restrictive dentin in the middle third of the canal. (g) The PTG S1 carves away coronal third restrictive dentin from the inside out. (f) The ProGlider mechanical file (Dentsply Sirona Endodontics) may be used to expand the smooth, super-loose No. (e) The shaping goal is to smoothly “connect the dots” apically with the dots coronally. (d) Soon-to-be discovered apical constriction width is identified by 2 dots and the anticipated one fifth to one third of the coronal width (nature’s diameters for structurally successful teeth) is also identified by 2 dots. The most common maximally appropriate shape is produced with the F2 (25/08) Finishing file. (c) Starting with the answer-the appropriate gutta-percha conefit is vividly imagined. (a) Convex triangular “cutting” blades have made Rotary shaping highly efficient, while Gold technology has made shaping safe. The features, sequence, purpose, and motion of ProTaper Gold (PTG) (Dentsply Sirona Endodontics). The principles of The Challenge Testing essentially remain the same.įigure 1. You can substitute any rotary brand for my ProTaper Gold distinctions and any reciprocation brand for my WaveOne Gold distinctions. These are the file systems I helped design and know the most about. In this clinical article, the examples I use for Rotary vs Reciprocation are ProTaper Gold (PTG) and WaveOne Gold (W1G) (Figures 1 and 2). However, if you take the self-test that I suggest at the end of this article, your choice of Rotary vs Reciprocation will be self-evident, perfectly scientific, and all about your and your patients’ needs. This article is an invitation to be self-educated about your best way to produce endodontic preparations that can be easily obturated.Īs a disclaimer, please note that I am a co-inventor of ProTaper and WaveOne file systems ( Dentsply Sirona Endodontics). The goal of this article is to explore and explain these 3 critical distinctions of Rotary vs Reciprocation so that the clinician is aware of these differences, understands his or her options, and makes the best choice for his or her particular practice and patient needs. When I am asked the question “Rotary vs Reciprocation: How Do I Choose?” my answer is “Rotary and Reciprocation,” because the predictability of both methods is similar they are just different in sequence, purpose, and motion. The purpose of endodontics is to heal lesions of endodontic origin (LEOs) where they exist and prevent LEOs where they do not exist. ![]() If we are careful and do it right, nature does the rest. We have a direct relationship to endodontic predictability. Predictable endodontic success, therefore, depends on (1) our knowledge of what to do, (2) our skill set in doing what we need to do, and, finally and most essentially, (3) our willingness to do it right. We are a self-selected culture that yearns to be better and to be our best.Įndodontic success rarely depends on a dental lab or whether or not the patient even cleans his or her teeth! Endodontic success does depend on the thoroughness of cleaning, shaping, and 3-D obturation-the classic and time-tested Endodontic Triad. As dentists, we are built that way and that’s how we think. INTRODUCTION As a practicing endodontist and a clinical endodontic educator for more than 30 years, the most frequent question I am asked about technique is: “Is it predictable?” While every dentist wants his or her endodontic treatment to be easier, more efficient, simpler, and profitable, in the end, it is predictability that trumps all considerations.
