    Facial and occlusal,
    Facial and cervical,
    cervical and lingual,

    Facial and cervical,
    it will be facial and cervical sa we can't see the occlusal embrasure from facial view.


    Max CI has maximum inclination facially
    from the sagittal view to the plane of occlusion.

    500
    5000

    please explain

    its a percentage based question..
    0.05% of F in 100
    ? in 1000000
    =0.05x1000000/100
    =500

    Enamel rods converge as they pass from the dentinoenamel junction toward the surface in the area of the
    a. cervical line of permanent teeth.
    b. cervical line of primary teeth.
    c. fissures.

    18.. As the mouth is opened widely, the articular disk moves in what direction in relation to the articular eminence?
    A Laterally
    B. Anteriorly
    C. Posteriorly
    D. Medially
    E. Superiorly

    articular disc moves anteromedially as the lat pt moves in tht direction..



    On the occlusal surface of a maxillary molar, the groove that representt the working path of the distofacial cusp of the mandibular molar is the
    1. central groove.
    2. facial groove.
    3. lingual groove.
    4. distal oblique groove.

    remember this mandi moves in distofacial direction during lat working side movement...n maxillary teeth moves in mesiolingual direction...

    The answer is osteosarcoma​

    Disrupted and disorganised periosteum may appear "hair on end " or "sunburst"
