ANATOMY-DRIVEN ENDODONTICS
It is often said that the root canal system functions like a “roach motel”—microorganisms check in but don’t easily check out. That said, endodontic success rates can be significantly enhanced when we prioritize disinfection especially within anatomically complex systems. The presence of lateral radiolucencies can serve as valuable guides, allowing the clinician to map out the egress of irritants.
In this particular case, a conservative shaping protocol (17/04) was utilized and focused on optimized chemical debridement. Extensive anatomy was uncovered. However, no mechanical scouting or instrumentation of lateral anatomy was attempted—these areas were addressed via GentleWave®’s mechanisms of action, which facilitate effective irrigation, cleaning, and disinfection of uninstrumented anatomies.
Our Key Takeaways:
• Root canal anatomy governs treatment outcomes; the more comprehensively we address it, the more predictable our results.
• While vertical sealer surplus can often be controlled by the clinician, lateral surplus is more variable and largely anatomy-dependent.
• Clinically, patients are less concerned with radiographic evidence of sealer surplus and more focused on pain relief and long-term tooth retention. Importantly, it is the sealer—not gutta-percha—that provides the critical seal.
• That said, clinicians must remain vigilant regarding anatomical regions where sealer surplus could affect adjacent neurovascular structures. (See the post by .agambhatnagar dated Friday, July 18: “When Puffing Can Be Dangerous” for further discussion.)
Exceptional casework by our professional partner, Dr. Scott Hetz, exhibiting complete healing at the 1-year continuing care appointment, and demonstrating that sealer surplus is irrelevant to the outcome of the case. NOTE: In our practice, disinfection will never be overrated.
