Nerve injury: This is primarily an issue with extraction of third molars, but can occur with the extraction of any tooth should the nerve be close to the surgical site. Two nerves are typically of concern, and are found in duplicate (one left and one right): 1. the inferior alveolar nerve , which enters the mandible at the mandibular foramen ...
Coronectomy should be considered if there are signs that the patient is at a high risk of nerve damage during extraction: Lower wisdom tooth is shown to be close to the inferior alveolar canal radiographically: [6] Signs of narrowing or diversion of the canal; Roots are darkened/ Canal is interrupted; Interruption of lamina dura
Temporary filling-materials allow the creation of hermetic coronal-seals preventing from coronal microleakage (i.e. contamination of the root canal by bacteria); their presence over the entire time-period to fill the root canal and restore the tooth crown is mandatory, for increasing the probability of the endodontic-treatment success.
For example, the incidence of nerve injury in teens removing third molars is much lower than the incidence in patients 25 and older. [7] This risk increases 10 fold if the tooth is close to the inferior dental canal containing the inferior alveolar nerve (as judged on a dental radiograph). [8]
The most common treatment for recurrent pericoronitis is wisdom tooth removal. The risks of wisdom tooth removal are roughly proportional to the difficulty of the extraction. Sometimes, when there is a high risk to the inferior alveolar nerve, only the crown of the tooth will be removed (intentionally leaving the roots) in a procedure called a ...

In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
Infiltration analgesia is deposition of an analgesic (pain-relieving) drug close to the apex of a tooth so that it can diffuse to reach the nerve entering the apical foramina. [1] It is the most routinely used in dental local treatment.
