Nasopalatine Nerve Block
Anesthetise the soft and hard tissue of the maxillary anterior six teeth - from canine one side to
canine other side.
Technique - approximately 1,5 cm posterior to the alveolar crest between the central incisors -
posterior to the incisive papilla; depth less than 10mm and inject 0,3 - 0,5 ml




Submental Space
Anterosuperiorly: mental symphysis (Apex)
Posteroinferiorly: Hyoid bone (Base)
Superolaterally: Anterior bellies of digastric muscles
Floor: mylohyoid muscle
Roof: superficial fascia containing platysma
What type of infection might the submental space be involved in?
It may be involved in infections of mandibular incisors causing a swelling at the point of chin.

Submandibular Space
Boundaries of submandibular space
1) lateral: superficial fascia and body of manble
2) medial: mylohyoid muscle
3) superior: mylohyoid line of mandble and mylohyoid muscle
4) inferior: hyoid bone
What are the contents of the submandiblar space?
(1) the submandibular gland
(2) lymph nodes
(3) the hypoglossal nerve
(4) the nerve to the mylohyoid
(5) the facial artery and submental branch.

Where might infection occur in order to effect the submandibular space?
Infections emanate from mandibular molars that have their roots located below the mylohyoid line
