Inferior dental plexus
Inferior Dental Plexus
The Inferior Dental Plexus is a complex network of nerves located within the mandible, primarily responsible for the innervation of the lower teeth. It is a part of the trigeminal nerve system, specifically the third division known as the mandibular nerve.
Anatomy[edit | edit source]
The Inferior Dental Plexus is formed by the inferior alveolar nerve, a branch of the mandibular nerve. It enters the mandible through the mandibular foramen, running through the mandibular canal and giving off branches to the lower teeth and gums. The plexus also includes the mental nerve, which exits the mandible through the mental foramen to supply the skin and mucous membrane of the lower lip and chin.
Function[edit | edit source]
The primary function of the Inferior Dental Plexus is to provide sensory innervation to the lower teeth. This includes the perception of pain, temperature, and pressure. It also supplies the gums and the skin of the lower lip and chin.
Clinical Significance[edit | edit source]
Understanding the anatomy and function of the Inferior Dental Plexus is crucial in various dental procedures, such as root canal treatment and dental implant placement. Damage to the plexus during these procedures can result in numbness or pain in the lower teeth, gums, and chin.
