Molars

Molars

  • Wider bucciology

  • Lingual pit

  • Oblique ridge is only on maxillary molars

  • Dilaceration - a bent root

Permanent maxillary 1st Molar

  • Has the largest crown of all of the molars

  • Where do we usually collect caculus on this tooth

  • Buccal groove - making a line right through the crown - have way to the CEJ

  • Even of the 5th cusps is not detectable, the lobe

  • The mesaial lingual cusp is larger and longer


Cusp of Carabelli

  • 3rd lingual susp

  • Has a groove that may not even be

  • CEJ cureveds more on the mesial side

  • All maxilaary teeth has three roots

  • The lingual side looks like a banna

  • the buccal side look like pliers from the buccal side

  • hypererupt- when a tooth keeps coming down because the occusal tooth is mmissing and not stoping growth

Maxillary Second Molars

  • Only has 4 developmental lobes

  • buccal groove is more towards the distal

  • from the lingual view dl cusp is smaller and shaper than ml cusp

  • has supplemental groove which gives the wrinkled look

  • all roots are smaller then max 1st molar

  • Sometime root fusion is common

Maxillary 3rd Molars

  • Roots are usually fuses on this tooth

  • can be heart shaped or rhoboidal shape

  • no oblique ringle present

Mandibluar Molars

  • Mand only has 2 roots

Man 1st Molar

  • Hardest working tooth

  • Prone to decay

  • 3 bucaal cusp, mb. db, d

    • mesial tallest, db middle, shortest

    • distal cusp has the shapest cusp

  • Crown tips towards the lingual

  • has a buccal belly

  • mesial root is longer and wider than distal root

  • bifurcated

  • pentagonal shaped - 5 sided

  • no transvere ridge

  • 5 development grooves

  • buccal pits are prone to decay

Mandilaur 2nd molars

  • mb and db is usually the same size

  • the ml and the dl cusp is usually the same size

  • the crown slants towards the lingual

  • mesial root is wider than distal root

  • smaller buccal belly and mesial ridge than 1st mand molar

  • makes a cross shaped pattern on the occusal surfaces

  • more supplemental grooves makes it look more wrinlked than 1st molar

  • usually has two pulp canals 2 in mesial 1 in the desial

Mandubilar 3rds

  • Pericornoitis
