The effect of occlusal disorders on root canal treatment procedures

Several aspects of temporomandibular disorders, including occlusal parafunction, mal-occlusion, bruxism and clenching may affect decision-making and treatment outcomes in single teeth that require root canal treatment. Occlusal disorders may have an impact on pulp biology, resulting in calcific metamorphosis, pulp necrosis or apical periodontitis. In addition, occlusal stress and trauma may affect tooth structure, resulting in crack propagation and vertical root fracture. Finally, an increasing percentage of teeth are affected by external cervical root resorption. The aim of this lecture is to provided up-to-date insights in a relatively unforeseen clinical issue that potentially affects endodontic diagnosis and treatment planning.
