The dental pulpal histology was studied experimentally in rabbits after the inferior alveolar neurovascularity damage and nerve graft. The results revealed that the dental vitality was gradually repaired at different intervals after the inferior alveolar neurovascularity damage. In the early damaged period the pulpal blood vessels were reduced in number and some of them were swollen and permeable, in the late period the structure of the microvascular system became normal and abundant. The pulpal architecture was altered in the initial stage and with the tendency to repair gradually. The pulpal axon degenerated in early stage and reinnervated later. The authors indicate that there are no evident affections for dental pulpal tissues whatever the inferior alveolar neurovascularity is damaged and repaired. This has an important clinical value to define the dental pulp vitality in mandibular subapical osteotomy and tumor resection.

D008340	Mandibular Nerve	A branch of the trigeminal (5th cranial) nerve. The mandibular nerve carries motor fibers to the muscles of mastication and sensory fibers to the teeth and gingivae, the face in the region of the mandible, and parts of the dura.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D003782	Dental Pulp	A richly vascularized and innervated connective tissue of mesodermal origin, contained in the central cavity of a tooth and delimited by the dentin, and having formative, nutritive, sensory, and protective functions.

D003791	Dental Pulp Test	A diagnostic aid used in evaluating the physical health of teeth. It involves using a tool that transmits hot or cold temperatures, or electric currents to a tooth's surface. The sensitivity to hot or cold or to the currents on a tooth can determine if there are problems with that tooth.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016067	Nerve Transfer	Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.

D061221	Trigeminal Nerve Injuries	Traumatic injuries to the TRIGEMINAL NERVE. It may result in extreme pain, abnormal sensation in the areas the nerve innervates on face, jaw, gums and tongue and can cause difficulties with speech and chewing. It is sometimes associated with various dental treatments.
