Endodontic Considerations: Physiology of the Accessory Canals of the Dental Pulp

Abstract

Access to endodontic therapy by the general population is often limited by the high expense of these procedures (i.e., sometimes requiring the expertise of a dental specialist in Endodontics). The segments of the endodontic apparatus (i.e., periapical complex, accessory canals, and root canal space) with their unique qualities as to spacial relationships, composition of microbial flora, immunological considerations, and host factors, function together leading to the success of initial endodontic treatment or subsequently to its failure and need for retreatment. Sealing of accessory canals can directly impact endodontic success whether being filled passively during root canal therapy, healing them with a “dentinal bridge”, or approached surgically in a preventive or retreatment mode. Regeneration and repair of periapical alveolar bone and periodontal ligament signals a clinical success while absence of these healing factors constitutes an endodontic failure. Unless they are sealed passively during instrumentation or obturation, accessory canals can spread microbial infection to the root canal space and/or periodontal structures.
