EndodonticsIf the main canal is well obturated and the tooth becomes asymptomatic, unfilled accessory canals often heal spontaneously. Immediate surgical intervention is not indicated unless symptoms persist or develop.

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.

Community DentistryThe Simplified Oral Hygiene Index (OHI-S) is a tool used to assess oral hygiene status by evaluating specific tooth surfaces. The teeth mentioned in option 1 include the lingual surfaces of the lower first molars (36, 46) and the facial surfaces of the upper incisors and canines (11, 16, 26, 31). These surfaces are typically assessed because they are representative of overall oral hygiene and are commonly affected by plaque accumulation.

AnatomyCerebrospinal fluid (CSF) rhinorrhea occurs when there is a leak of CSF through the nasal cavity, often due to a defect in the skull base. The ethmoid bone is the most common site for such leaks because of its thin structure and proximity to the nasal cavity.
