  1. ORAL ANATOMY UNCLASSIFIED//REL TO NATO/ISAF

  2. Oral Anatomy • Function of mouth • External mouth • Internal mouth • Oral vestibule • Oral cavity proper • Tongue • Salivary gland CFHSTC Clin Perio Crse 0013

  3. Functions of mouth The first part of digestive system wherein mastication occur. It receives food (ingestion) and break up the food into smaller pieces (digestion). Takes part in respiration as well as in speech production Lastly it conveys emotion

  4. External Mouth • Composed primarily of the upper and lower lips • Lips separate from the skin by vermillion border

  5. External Mouth Naso-labial fold Philtrum Upper lip Commissure Oral fissure Vermillion border Mento-labial fold Lower lip

  6. Internal Mouth Divided into 2 parts: • Oral vestibule • Oral cavity proper

  7. The Oral vestibule A slit like space bounded: Laterally by cheek and lips Medially by the buccal and labial surfaces of the upper and lower teeth Posteriorly by the retromolararea

  8. The Oral vestibule • A- attached gingiva • B- free gingiva • C- upper labial frenum • D- mucobuccalfold • E- interdentalPapilla • F- cheek • G- oral vestibule • I- mucolabialfold

  9. The Oral vestibule Upper buccal frenum Lower buccal frenum

  10. The oral cavity proper Bounded: Laterallyby palatal and lingual surfaces of the upper and lower teeth Superiorly by the palate (hard & soft) Inferiorly by the tongue and or the floor of the mouth Posteriorly by the isthmus of fauces

  11. Internal Mouth

  12. Incisisve papilla Palatine Rugae Median palatine raphe Maxillary tuberosity Superior boundary- Palate Fovea Palatina

  13. Ventral surface of the tongue Lingual Frenulum Sublingual fold Inferior boundary- floor of mouth Sublingual caruncle

  14. The tongue Composed of: Anterior 2/3 (body)and Posterior 1/3 (root) Presence of lingual papillae: Filiform papilla Fungiformpapilla* Foliate papilla Circumvallate papilla * (* that contains taste buds )

  15. Palatopharyngeal arch Uvula Isthmus of fauces Posterior boundary

  16. Salivary Glands • Parotid Gland: • the largest of the 3 salivary gland • Located anterior to the ear, extending from the cheek bone up to the lower jaw • Parotid or Stensens’ duct opens at the oral vestibule opposite upper second molar 2. Submandibular gland: • Located at the floor of the mouth posteriorly • Whartons’ duct opens at the sublingual caruncle 3. Sublingual gland: • Located at the floor of the mouth anteriorly • The numerous ducts of SL gland open at the sublingual fold
