BDS III lectures
Dr S. Singh

2. Blood supply Gingiva have a rich blood supply derived from 3 sources
Supraperiosteal vessels
Periodontal ligament vessels
Alveolar crest vessels
These link in the gingiva to form capillary loops in the CT papillae and drains in to the regional lymph nodes

4. Lymphatic drainage
From mandibular gingival lymph nodes  cervical  submandibular  submental
From maxillary gingival lymph nodes  deep cervical lymph nodes

5. Nerve supply Derived from branches of the trigeminal nerve
A number of nerve endings is identified in the gingival CT
Tactile corpuscles
Temperature receptors
Pain receptors
