Exam Review

  • posterior tooth to most likely ahve one pulp horn

    • mandibular first PM

  • In cervical cross section, the root of the mandibular canine is

    • broader mesiodistally on the facial side than on the lingual

  • slight inciso-cervical concavity on the labial crown surface of canines

    • mesiolabial developmental depression

  • occlusal view shape of tooth 14 (max first molar) = rhomboid

  • the root with the widest faciolingually = mesial root of mandibular 1st molar

  • occlusal view, mandibular first molars taper lingually

  • Which root of which tooth can extend beyond the crowns height of countour

    • Distal root of mandibular 1st molar

  • crown of maxillary canine

    • distal portion displays convexity

  • longest root of maxillary first molar is

    • palatal root

  • only premolars to not have a central groove

    • 3 cusp man. 2nd premolar and mandibular first premolar

  • in primary teeth, the first molar is replaced by the first premolar

  • the oblique ridge traverses across the tooth between the

    • Obtuse angle : DB + MD

    • Acute": MB + DL

  • The mesial proximal surface of a mandibular canine crown is almost parallel to the long axis of the tooth

  • The cusp of Carabelli occurs with sufficient frequency to be considered a normal variation in the permanent maxillary first molar and the primary (deciduous) maxillary second molar

  • mesiobuccal = mandibular 2nd molar aids in telling left from right 2nd molar, lies in mesiobuccal gingival 1/3

  • Which developmental groove in the mandibular 2nd molar runs in the same direction as the lingual groove

    • facial

  • mandibular 2nd premolar = only premolar with a central fossa

  • To tell maxillary first premolars apart = look for the mesial marginal ridge groove and the mesial crown concavity

  • In the mandibular arch, the greatest lingual inclination of the crown is seen in a permanent first premolar

  • The mandibular 2nd premolar and maxillary first molar taper towards the facial rather than towards the lingual

  • On maxillary canines, the middle facial lobe includes the cusp tip

  • The mesiobuccal groove doesn’t radiate out from the central fossa
