Effect of Endodontic Treatment Procedures on Canal Shape and Mechanical Properties of a Tooth

Endodontic treatment procedures induce changes in tooth structure and may shift stress distributions in treated roots that make them more prone to fracture. This chapter discusses mechanical properties and changes in dentin characteristics and shape of the root canal caused by root canal therapy. Moisture, irrigants, medicaments, obturation materials, temperature rise, and canal taper may induce these changes.
