The Role of Modern Technologies for Dentin Preservation in Root Canal Treatment

Attempting exploration at the expense of dentin tissue to reveal anatomical variation is still a common practice in root canal treatment, mainly because it relies on bi-dimensional radiographic images and clinical assessments to comprehend root morphology and root canal anatomy. The main purpose of this chapter is to understand the role of technological advances in finding the appropriate resources and maneuvers to (a) completely treat root canal anatomy avoiding residual intracanal infection, (b) balancing the size of the access cavity and the degree of root canal enlargement with the requirements of irrigation methods to achieve optimum disinfection, and (c) preserving root dentin during instrumentation to maintain the mechanical integrity of the root, minimizing the risk of fractures, all of them considered relevant causes of endodontic treatment failure.
