What is the order of distance of furcations from the cervical line? - ANSWER Distal -distance of furcations from cervical line M&lt;B&lt;D - You get further away the more distal you go The oblique ridge of the maxillary 1st molar develops which boundary of the central fossa? - ANSWER Distal boundary of the central fossa The obtuse corners of the maxillary 1st molar coincide with: - ANSWER The direction of the oblique ridge The center of the oblique ridge on a maxillary 1st molar is at the same level as the height of the: - ANSWER The marginal ridge The oblique ridge connects which cusps? - ANSWER ML and DF cusps The ML cusp of the maxillary 1st molar occludes in: - ANSWER The central fossa of the mandibular molars Greatest FL diameter of the crown for all teeth - ANSWER Maxillary 1st molar -think cusp of carabelli The closest in size FL vs. MD of any MAXILLARY POSTERIOR TOOTH. [could ask just posterior teeth which includes maxillary and mandibular] - ANSWER Maxillary 1st Molar Maxillary 1st molar has a wider MD width toward the ___ than the ___ - ANSWER lingual, facial The only cusp that is not a part of the molar cusp triangle of the maxillary first molar - ANSWER DL Largest and longest posterior cusp of the maxillary 1st molar is: - ANSWER ML of maxillary 1st molar Which tooth is most likely forced into the maxillary sinus during extraction? - ANSWER Maxillary 1st molar Which tooth has a distal concavity that can pose special problems in matrix placement? [Which tooth has the mesial concavity that can pose special problems in matrix placement?] - ANSWER Maxillary 1st molar Maxillary 1st PM Which tooth has a shorter DL groove: Maxillary 1st Molar or Maxillary 2nd molar? - ANSWER Maxillary 1st Molar Which cusp is the only one not a part of the molar cusp triangle of the maxillary 2nd molar? - ANSWER DL [Same as Maxillary 1st Molar] If the DL cusp is not present on the maxillary 2nd molar, you will have what shape? - ANSWER Three cusp type heart shape The roots of the maxillary 2nd molar tend to be - ANSWER Less divergent and have greater distal inclinations [as you move back you're running out of room so roots have to be squished together] The cross sectional outline at the cervical for maxillary 2nd molar is what shape? - ANSWER Triangular The groove pattern for mandibular 1st molar is what shape? - ANSWER Y or W or Dryopethicus pattern The occlusal outline of a mandibular 1st molar is what shape? - ANSWER Pentagon The smallest cusp of the mandibular 1st molar - ANSWER Distal cusp [#5] The largest cusp of the mandibular 1st molar What is the rank from largest to smallest cusp on the mandibular 1st molar? - ANSWER Mesio-facial (MF) MB&gt;ML&gt;DL&lt;DB&gt;D Which tooth has the LARGEST M-D crown dimension of ANY other tooth? - ANSWER Mandibular 1st Molar [Think of 3 buccal cusps] The only MANDIBULAR teeth that are wider MD than FL - ANSWER Mandibular molars The only POSTERIOR teeth that are wider MD than FL? [The closest in size FL vs. MD of any MAXILLARY POSTERIOR TOOTH] - ANSWER Mandibular Molars Maxillary 1st Molar Greatest M-D diameter of all molars - ANSWER Mandibular 1st Molar The largest FL crown dimension of ANY other MANDIBULAR tooth: The greatest FL crown dimension of ALL teeth: - ANSWER Mandibular 1st molar -Maxillary 1st molar has greatest FL diameter of all teeth (cusp of carabelli) The largest occlusal-cervical crown dimension of any mandibular molar? - ANSWER Mandibular 1st molar In relation to the ascending ramus, the facial surfaces of mandibular molars are located: - ANSWER medial to the border of the ascending ramus A key feature that differentiates a mandibular 1st molar and a 2nd molar is: How many for Mandibular 1st?
