Root canal retreatment is traditionally consider an “all or none” treatment approach. Meaning, all restorative and obturation material must be removed from the entire root canal space of all roots regardless of individual periapical health. In contrast, surgical endodontics is not viewed as an “all or none” approach. It is a generally accepted that only the diseased root(s) should be addressed via root end resection and root end filling. Knowledge gained from CBCT imaging has introduced a new reasonable treatment option for endodonticaly treated teeth presenting with post treatment disease. This new concept allows the clinician to make predictable treatment decisions based on the periapical status of an individual root(s) rather than make assumptions about the tooth as a whole. A “selective root retreatment” combines the approach of an orthograde retreatment with the selectivity of a retrograde surgical root resection. It is being suggested that retreatment could be limited to a single root or roots clearly demonstrating periapical pathology while leaving the root(s) with no visible or perceived pathology untouched.

I thought Dr. Nudera's presentation was well laid out, very thoughtful and engaging describing his rationale for selective root retreatment, would highly recommend it to others who do endo retreatments. It definitely opened my eyes and gave me more options to think about when treating my own patients who need endo retreats.
