1. Blood Supply of the
Jaws and Teeth
By : Ayaan Maqsood

3. Arties carry blood from
the heart to the tissues
of the body.

4. The principal arteries which
supply the head and neck
are the common carotid
arteries.

5. At about the level of hyoid
bone each common carotid
artery divides into an
external carotid artery and
an internal carotid artery.

6. Internal carotid artery
supplies the tissues of the
cranium and the eyes.

7. External carotid artery, with
its many branches,
supplies the exterior of the
head, the face and much of
the neck.

8. External carotid artery, just
above its division from the
common carotid artery
gives off the lingual artery
which supplies the tongue.

9. Just above the origin of
lingual artery, it gives off
another branch, the facial
artery, which supplies the
soft tissues of the side of
the face.

10. At about the level of the
lower part of the ear, the
external carotid divides
into its two main terminal
branches, the maxillary
artery and the superficial
temporal artery.

11. Maxillary artery through
various branches supply
the bones of the jaws, the
teeth and their supporting
tissues.

12. Important branches of Maxillary
artery are :-

13. Inferior alveolar artery
supplies mandible and the
mandibular teeth.
Enters to mandible through
mandibular teeth.

14. Posterior superior artery
Supplies the maxilla and
the roots of the last
maxillary molar tooth.
Bone and teeth including the
first bicuspid.

15. Palatine artery supplies the
soft tissues of the hard
palate, gingival tissue on
the palatine or lingual side
of the maxillary teeth.
Emerges into the roof of the
mouth through the Greater
palatine foramena.

16. Infraorbital artery supplies
incisors and cuspids of the
maxilla.
