A fully automatic navigation assistant for root canal therapy? What may initially sound like robo-doc treatment or treatment by remote control will take endodontics a significant step forward on the way to sustainable, reliable preparation. Cases presented in this article illustrate how digital endodontic assistance systems will revolutionise everyday treatment in the future.

Many years ago already, the anatomy of root canals was described as showing variability and being of a complex nature. According to Vertucci, the mandibular first premolar has one canal at the apex in 74.0% of teeth, two canals at the apex in 25.5% and three canals at the apex in 0.5% of teeth.

The need for an endodontic skill set within the profession is higher than it has ever been. Culturally and socially, there have been significant changes in patient perception to the news that a tooth is in trouble, where the solution is either root canal treatment or removal. I am old enough to have treated patients who needed the replacement of complete dentures that were a “wedding gift” in their youth. As a gesture of goodwill to the bride in waiting, wholesale extractions and the provision of complete dentures were gifted to ensure the absence of dental problems or expense throughout their new found love.

Completely disinfecting the canal system is challenging when all factors are considered. If we are looking at the nano level there are approximately 76,000 dentinal tubules per square millimetre of dentine. Each of which can harbour a colony of bacteria. Then there may be inaccessible anatomy such as lateral canals, apical deltas or fins.

The mechanical and biological objectives of shaping root canals were beautifully described by Herbert Schilder in 1974. As relevant today, in the era of automated canal preparation techniques, as they were in the days of hand preparation techniques, these objectives provide the rationale for the designs, tapers and tip sizes of modern-day endodontic instruments. Shaping the root canal facilitates 3-D irrigation and cleaning of the root canal system of all pulp tissue, bacteria and their related by- products. Importantly, shaping the root canal provides the resistance form and facilitates filling the root canal system.
