EndodonticsWhen moderate extrusion of obturating material and sealer beyond the apex occurs, it is undesirable for several reasons. While it does not necessarily mean the prognosis is poor, there is a higher likelihood of postoperative discomfort due to the potential for chemical irritation of the periapical tissues. Additionally, if the sealer is not resorbed, it may cause a foreign body reaction, and gutta-percha extrusion can sometimes lead to severe periradicular reactions. The best approach in such a case is to obturate the remaining canal up to the point of obstruction and observe the patient's symptoms and healing response.

contain fibers from the masseter muscle, which is located more anteriorly and
plays a different role in mastication.
