As the dental pulp is a highly vascularised and innervated region of the tooth, it is the site of origin for most pain-related sensations. [12] The dental pulp nerve is innervated by one of the trigeminal nerves, otherwise known as the fifth cranial nerve. The neurons enter the pulp cavity through the apical foramen and branch off to form the ...
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 ...
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]
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.
It is a branch of the inferior alveolar nerve. It provides motor innervation the mylohyoid muscle, and the anterior belly of the digastric muscle. It provides sensory innervation to part of the submental area, and sometimes also the mandibular (lower) molar teeth, requiring local anaesthesia for some oral procedures.
The mandibular nerve (V 3) carries sensory information from the lower lip, the lower teeth and gums, the chin and jaw (except the angle of the jaw, which is supplied by C2-C3), parts of the external ear and parts of the meninges. The mandibular nerve carries touch-position and pain-temperature sensations from the mouth.
The greater palatine nerve is a branch of the pterygopalatine ganglion. This nerve is also referred to as the anterior palatine nerve , due to its location anterior to the lesser palatine nerve . It carries both general sensory fibres from the maxillary nerve , and parasympathetic fibers from the nerve of the pterygoid canal .
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
