    • DB

    • MB

    • ML

    Correct Answer
    A. ML
    Explanation
    The correct answer is ML, which stands for mesiolingual. The mesiolingual cusp is the largest and longest cusp on the maxillary molars. It is located on the inner side of the tooth, towards the front (mesial) and towards the tongue (lingual). This cusp is important for chewing and grinding food, as it helps in the breakdown of food particles.

    Rate this question:

  • 3. 

    Molar crowns incline towards which surface?

    • Lingual

    • Buccal

    • Mesial

    • Distal

    Correct Answer
    A. Lingual
    Explanation
    Molar crowns incline towards the lingual surface. This means that the crown of the molar is tilted or slanted towards the inner or back side of the mouth. The lingual surface refers to the surface of the tooth that is closest to the tongue. This inclination helps with the chewing and grinding of food, as well as providing support and stability to the tooth.

    • ML

    • MB

    • DL

    • DB

    Correct Answer
    A. MB
    Explanation
    The largest mandibular molar cusp is the MB (mesiobuccal) cusp. This cusp is located on the mesial and buccal aspect of the mandibular molar, making it the largest and most prominent cusp on the tooth. It is responsible for the initial contact during chewing and plays a crucial role in the mastication process.

  • 5. 

    ____________ molars are trifuracted.

    Correct Answer
    Maxillary
    Upper
    Explanation
    Maxillary molars refer to the molars located in the upper jaw. The term "trifurcated" means that these molars have three roots. Therefore, the correct answer is "Maxillary, Upper" as it accurately describes the specific type of molars that are trifurcated.

    Rate this question:

  • 6. 

    Match the following terms associated with maxillary first molars

    • #3 & #14

    • #2 & #15

    • No cusp of Carabelli

    • Cusp of Carabelli

    • DB to ML Oblique ridge

    • 5 functional cusps

    • 4 functional cusps

    Correct Answer(s)
    A. #3 & #14
    A. Cusp of Carabelli
    A. DB to ML Oblique ridge
    A. 4 functional cusps
    Explanation
    The maxillary first molars typically have a cusp of Carabelli on the mesiolingual (ML) cusp (#14). Additionally, they have a prominent oblique ridge running from the distobuccal (DB) cusp to the ML cusp. In terms of functional cusps, maxillary first molars have four functional cusps, which include the mesiobuccal (MB), distobuccal (DB), mesiolingual (ML), and distolingual (DL) cusps. Therefore, the correct matching terms for #3 and #14 would be Cusp of Carabelli, DB to ML Oblique ridge, and 4 functional cusps.

  • 7. 

    Which types of teeth are the exception to having a height of contour on the buccal cervical third and lingual middle third?

    • Lower first molars

    • Lower second premolar

    • Upper second premolar

    • Upper first molars

    Correct Answer
    A. Upper first molars
    Explanation
    The types of teeth that are the exception to having a height of contour on the buccal cervical third and lingual middle third are Upper first molars. Typically, the height of contour (the greatest bulge or widest point on a tooth) is found on the buccal cervical third for posterior teeth and lingual middle third for most teeth. However, upper first molars have a unique anatomy with significant cusps and occlusal surfaces that can alter the typical pattern of contour heights.

    • Offset central groove

    • Straight central groove

    • #18 & #31

    • #17 & #30

    • No transverse ridges

    • Parallel transverse ridges

    Correct Answer(s)
    A. 4 cusps
    A. Straight central groove
    A. #18 & #31
    A. Parallel transverse ridges
    Explanation
    Mandibular second molars typically have 4 cusps, a straight central groove, and parallel transverse ridges. Additionally, they are located at positions #18 and #31.

    Checkmark all of the terms associated with maxillary second molars:

    • #2 & #15

    • #3 & #14

    • Rectangle

    • Rhomboid

    • 5 functional cusps

    • 4 functional cusps

    • No cusp of Carabelli

    • Cusp of Carabelli

    • DB to ML oblique ridge

    Correct Answer(s)
    A. #2 & #15
    A. Rhomboid
    A. 4 functional cusps
    A. No cusp of Carabelli
    A. DB to ML oblique ridge
    Explanation
    Maxillary second molars typically have two roots, referred to as #2 and #15. The shape of the crown of these molars is rhomboid. They have four functional cusps, meaning that these cusps are involved in the chewing and grinding of food. There is no cusp of Carabelli present on maxillary second molars. Additionally, these molars have a distinguishing feature called the DB to ML oblique ridge, which extends diagonally from the distobuccal cusp to the mesiolingual cusp.
