  1. TOOTH MORPHOLOGY ANATOMICAL STRUCTURES

  2. Anatomical Structures • APEX – at or near the end of the root APICAL FORAMEN – opening in bone h through which nerves and blood vessels enter

  3. Anatomical Structures • FURCATION – dividing point of a multi-rooted tooth • Furca means “fork” • BIFURCATED – branched in two • ‘bi’ – means two (two roots) • TRIFURCATED – branched in three • ‘tri’ – means three (three roots)

  4. Anatomical Structures • GROOVE – a linear channel or line • Buccal groove – groove on buccal surface • Developmental groove – groove formed during development of the crown • Supplemental groove – shallow grooves radiating from developmental grooves; gives tooth a sort of wrinkle

  5. Anatomical Structures • LOBES – separate divisions that come together to form a tooth • CUSP –rounded or pointed mound on crown of a tooth • Cusp of Carabelli – 5th cusp found only on mesial lingual surface of max. 1st molars

  6. Anatomical Structures • Cingulum – convex area on the lingual surface of the anterior teeth, near the gingiva Formed from a lobe • Mamelons – 3 bulges on incisal edge of newly erupted centrals and sometimes laterals; (wear away in time) Formed from 3 lobes

  7. Anatomical structures • Fissure – a deep groove or cleft; usually the result of an imperfect developmental groove • Pit – small depression on surface of tooth; where fissures cross

  8. Anatomical structures • Pits and fissures • The areas on the tooth where decay usually begins Molars, especially 1st mol., should have sealants placed

  9. Anatomical structures Fossa – a shallow rounded or angular depression on a surface usually the concave areas of a tooth on the lingual or sometimes occlusal

  10. Anatomical structures • Ridge – a linear elevation of enamel • Ridge receives its name from location • Marginal ridge – elevations on mesial & distal • Oblique ridge – slanting ridge across occlusal • Triangular ridge – ridge or elevation that widens to middle of occlusal surface • Transverse ridge – union of two triangular ridges across occlusal surface

  11. The End
