MOLARS, Dyandra Wirahana Hasan - 2106717682 - Coggle Diagram

- - - - This tooth are located laterally from both the maxillary second premolars of the mouth but mesial (toward the midline of the face) from both maxillary second molars.
    - - The crown is trapezoidal
      - Has 4 well-developed functioning cusps
      - The crown is relatively short
      - Usually 3 rooted
      - The distal Cementum Enamel Junction is relatively straight
    - - First Evidence of calcification: at birth
      - Enamel completed: 3-4 yr
      - eruption: 6 yr
      - Root Completed: 9-10 yr
  - - - The crown is trapezoidal and it has 4 cusp
      - The crown is shorter cervico-occlusally than that of the first molar, but the measurement of the crown buccolingually is about the same
      - 3 rooted which the root has the same height
      - Distolingual cusp is poorly developed and makes the development of the other three cusps predominate
    - - First evidence of calcification: 2 ½ yr
      - Enamel completed: 7-8 yr
      - Eruption: 12-13 yr
      - Root completed: 14-16 yr
  - - - Crown is shorter cervico-occlusally
      - root slope distally
      - has no lingual grove
      - The root are usually fused functioning into one root
    - - First Evidence Calcification: 7-8 yr
      - Enamel completed: 12-16 yr
      - eruption: 17-21 yr
      - Root Completed: 18-25 yr
- - - - Seventh tooth and second molar from the midline, in each upper quadrant of the permanent dentition
    - - 3 root
      - 4 cusp
      - The crown is shorter cervico-occlusally than that of the first molar
      - Distolingual cusp is poorly developed and makes the development of the other three cusps predominate
      - The mesial & distal outline are convex
    - - First Evidence of calcification: at birth
      - Enamel completed: 3-4 yr
      - eruption: 6 yr
      - Root Completed: 9-10 yr
  - - - The Cervical Line is relatively straight
      - The mesial root tapers apically from the cervix
      - Its design usually matches more closely the second mandibular molar in the number of cusps and occlusal design than it does the mandibular first molar. sometimes it has five cusp
      - has more than one root mostly two roots
      - Shows irregular development of the crown portion, with undersized or malformed roots
      - The root is usually shorter
      - The buccal cusps are short and round
    - - First Evidence of calcification: 8-10
      - Enamel completed: 12-16 yr
      - eruption: 17-21 yr
      - Root Completed: 18-25 yr
    - - The Mandibular Third Molar is a tooth that is laterally placed from both the mandibular Second molar and it is the last teeth in the mandibular arch. Also sometimes referred as "Wisdom tooth"
  - - - The sixth tooth from the midline in both mandibular sides and It is the largest and strongest tooth in the mandibular arch
    - - has 2 roots
      - largest tooth
      - Has 4 to 5 lobes
      - the crown is trapezoidal
      - Greater dimension of the crown mesiodistally
      - Shorter root trunk
      - three cusps may be seen:
    - - First Evidence of calcification: at birth
      - Enamel completed: 2 half-3 yr
      - eruption: 6-7 yr
      - Root Completed: 9-10 yr
