Tooth form and function

The arrangement of the teeth within the dental arches is known as:

• Occlusion

• Alignment

• Articulation

• Arrangement

The relationship of the dental arches when tooth contact is made is :

• Alignment

• Articulation

• Occlusion

• Retrusion

Which dental arch is wider, larger and has more esthethics embedded in it ?

• Maxillary arch

• Mandibular Arch

• Both dental arches

• When arches are in occlusion

From the proximal aspect in maxillary teeth, the least deviation in tooth alignment as compared the longitudinal axis is :

• Central incisor

• First premolar

• Lateral incisor

• Second premolar

From the proximal aspect in mandibular teeth, the least deviation in tooth alignment as compared the longitudinal axis is :

• Lateral incisor

• Central incisor

• First premolar

• Canine

An imaginary line that extends from the cusp tip of the mandibular canine along the facial cusp tips of the posterior teeth resulting in an anteroposterior curve is:

• Curve of Jaffar

• Curve of Spee

• Curve of Wilson

• Curve of Monson

From the frontal view, an imaginary curved line connecting the facial and lingual cusps of the posterior teeth is known as:

• Curve of Monson

• Curve of Anderson

• Curve of Wilson

• Curve of Spee

Which groove here is continous in all the teeth?

• Central groove

• Marginal ridge

• Central fossa

• Central pit

What is the primary function of the Plane of Occlusion?

• To maintain a flat surface for tooth contact

• To permit simultaneous functional contact in more than one area of the dental arch

• To align the teeth in a straight vertical line

• To ensure that teeth contact their namesakes in the opposing arch

In terms of tooth contact areas, what tends to happen as you move posteriorly in the mouth?

• Contacts appear at the same level on each tooth

• Contacts appear higher on each tooth

• Contacts appear lower on each tooth

• There are no significant changes in contact areas
