Tooth ankylosis refers to a fusion between a tooth and underlying bony support tissues. In some species, this is a normal process that occurs during the formation or maintenance of the dentition. [1] By contrast, in humans tooth ankylosis is pathological, whereby a fusion between alveolar bone and the cementum of a tooth occurs.
They then enter the alveolar canals on the infratemporal surface of the maxilla, and, passing from behind forward in the substance of the bone, communicate with the middle superior alveolar nerve, and give off branches to the lining membrane of the maxillary sinus and gingival and dental branches to each molar tooth from a superior dental ...
The inferior alveolar nerve (IAN), a branch of the trigeminal nerve (cranial nerve V), is a nerve that runs through the mandible (lower jaw) and supplies sensation to all the lower teeth, the lip and the chin. The lower teeth, and in particular the lower wisdom teeth, can therefore be in close proximity to this nerve.
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.
These high risk wisdom teeth can be further assessed using cone beam CT imaging to assess and plan surgery to minimise nerve injury by careful extraction or undertaking a coronectomy procedure in healthy patients with healthy teeth. [9] The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk ...
It branches from the infraorbital nerve within the infraorbital canal [1] [2] at around the midpoint of this canal and enters the canalis sinuosus.It passes through towards the nose before passing inferior-ward and ramifying [2] into branches which innervate the upper/maxillary incisor and canine teeth; [1] [2] it usually innervates all the anterior teeth.
The management depends on the type of injury involved and whether it is a baby or an adult tooth. If teeth are completely knocked out baby front teeth should not be replaced. The area should be cleaned gently and the child brought to see a dentist. Adult front teeth (which usually erupt at around six years of age) can be replaced immediately if ...
Pulp capping is a technique used in dental restorations to protect the dental pulp, after it has been exposed, or nearly exposed during a cavity preparation, from a traumatic injury, or by a deep cavity that reaches the center of the tooth, causing the pulp to die. [1]
