Endodontics - 3 Questions
Formocresol is a commonly used fixative and disinfectant in endodontic treatment. It is known to produce tissue fixation by causing coagulative necrosis. This is the process by which the proteins within the tissue are coagulated or precipitated, leading to the death of cells due to dehydration and denaturation. The necrotic tissue is then replaced by a fibrous connective tissue, which is essential for the healing process in the periapical region following root canal treatment.
The primary cause of weakening in an endodontically treated tooth is the loss of sound tooth structure during the access cavity preparation and subsequent canal instrumentation. The extent of this preparation, particularly the removal of marginal ridges and cusps, significantly compromises the tooth's structural integrity.
Irreversible pulpitis is characterized by sharp, severe pain that continues even after the stimulus (such as cold) has been removed.
