Over the years, there has been a great deal of discussion about how best to restore endodontically treated teeth, especially with regard to the need for a post. Some clinicians maintain that the role of a ferrule is more important than that of the post, while others feel strongly that posts enhance the survival of endodontically treated teeth.
Studies of patients ≤20 to ≥40 years of age have shown that both pulp chamber size and root canal diameter decrease as people age. Such changes may also result from carious lesions, deep restorations and periodontal disease.
Pivotal for successful treatment, profound anesthesia prior to endodontic therapy is not always easy to achieve, especially in the lower molar area.
