Morphology of Human Deciduous Mandibular Molar teeth

  1. 1. Deciduous Dentition Mandibular Molar Dr. Rooban Thavarajah
  2. 2. Mandibular First Molar  No resemblance to any teeth; primitive Dr. Rooban Thavarajah
  3. 3. Buccal        Mesial outline straight -little constriction @ cervix Distal outline converges; short distal side No DG but a depression seen Large MB cusp Mesial outline is flat Distal is more convex to buccal cusp Bifurcation is close to cervical line Dr. Rooban Thavarajah
  4. 4.  Lingual     Crown, root converge lingually on mesial surface, opposite on distal surface. DL cusp rounded ML – sharp and long MMR well developed Dr. Rooban Thavarajah
  5. 5.  Proximal    No resemblance to any teeth Mesial is extremely bulbous in cervical 1/3 Distal is more uniform Dr. Rooban Thavarajah
  6. 6.  Occlusal        Rhomboidal in shape MB line angle prominent ML cusp – largest, well formed, widest Mesiobuccal ridge pronounced May have short buccal groove, Lingual groove Central groove 3 pits (in 2 fossa) Dr. Rooban Thavarajah
  7. 7.  Roots     2 roots bifurcated Flat and broad flared Mesial root has a longitudinal groove Distal root is shorter and thinner Dr. Rooban Thavarajah
  8. 8. Dr. Rooban Thavarajah
  9. 9. Mandibular Second Molar       Similar to 1st permanent molar but small Typical constriction at cervix 5 cusps MB, DB, D ML, DL Mesiobuccal and Distobuccal groove separates the 3 buccal cusp Lingual groove separates the 2 lingual cusps Buccal cusps equal in size ~ lingual cusps Dr. Rooban Thavarajah
  10. 10.  Proximal   Roots are twice as long as the crown     Similar to permanent molar Long, slender and flared Mesial root may have a longitudinal groove Distal root –no groove Occlusal  Rectangular in shape Dr. Rooban Thavarajah
  11. 11. Dr. Rooban Thavarajah
