  • 27. Inf dental nerve does not occupy a single canal, but is plexiform in arrangement. It is also joined, directly, or thru its plexiform branches, by rami entering the bone as parts of neurovascular bundles, derived from attached muscles such as masseter. Such ‘accessory’ dental nerves ramify particularly in a plane lateral to the molar teeth, and their common occurrence accounts for the incomplete abolition of pain by inf. dental nerve block - Carter and Keen 1971
  • 28. The nerves which supply the incisor teeth form an elaborate plexus on the external aspect of the mandible after emerging from the mental foramen and before they re-enter the bone. - Starkie and Stewart 1931
