Answer |
| T/F: From the facial or lingual aspect, occlusal embrasures decrease
in relative size from anterior to posterior teeth. |
|
| T/F: Both sides of embrasures on a tooth will have a similar contour |
|
| T/F: From the facial or lingual aspect, the gingival/cervial
embrasures decrease in relative size from anterior to posterior teeth? |
|
| T/F: From the occlusal aspect, the lingual embrasure is normally
smaller then the buccal in posterior teeth? |
|
| T/F: From an incisal aspect, buccal and lingual embrasures are close
to equal in size in anterior teeth? |
|
| What does height of contour or crest of curvature mean? |
|
| As the contact area moves more cervically in the posterior arch, the
relative size of the incisal/occluso embrasure ____, while the relative
size of the cervical embrasure ____. |
|
| As the contact area moves more to the buccal in posterior teeth, the
relative size of the lingual embrasure becomes ____. |
|
| What is a marginal ridge? |
|
| Are marginal ridges normally bulkier in the anterior or posterior? |
|
| Where should the height of the marginal ridges be located in relation
to the adjacent teeth? |
|
| Why are the central developmental grooves of posterior teeth normally
aligned into one continuous valley? |
|
| T/F: The three major functions of human teeth are mastication,
esthetics, and phonetics. |
|
| T/F: The periodontium is the hard supporting tissues of a tooth. |
|
| T/F: The most primitive type of tooth crown is a double lobed/cone
conical shape. |
|
| T/F: A homodont has similarly shaped teeth that differ only in size.
|
|
| T/F: Animals with conical cusps can only perform up and down or
lateral movements with their jaws. |
|
| T/F: The periodontium will suffer if the dentist does not pay heed to
normal tooth form and alignment. |
|
| T/F: An iatrogenic imperfection is a naturally occurring one. |
|
| What is the name of the triangular shaped area between adjacent teeth
in the same arch cervical to the contact area? |
|
| What is the name of periodontuim that fills the interproximal space?
|
|
| What are the boudaries of the interproximal space? |
|
| The open space between the proximal surfaces of the two adjacent teeth
in the same arch, where they diverge facially or lingually, and incisally
(occlusally) or cervically from the contact areas is a/an ____________.
|
|
| Name the two embrasures seen when viewing the teeth from either the
facial or lingual aspects. |
|
| Name the two embrasures seen when viewing the teeth from the incisal
or occlusal aspect. |
|
| Which embrasure corresponds to the interproximal space? |
|
| T/F: The shape, length, and number of root branches are related to a
tooth's form and function. |
|
| Which tooth has the longest and strongest root in both arches? |
|
| Why are molars multirooted? |
|
| T/F: A tooth root is NOT directly related to crown form, placement in
the arch, and function. |
|
| T/F: Roots are widest toward cervical area and taper toward the apex.
|
|
| How many roots do anterior teeth and premolars normally have? |
|
| Although premolars normally have single roots, which premolar is an
exception? How many roots does that premolar have? What are the names of
the root branches? |
|
| How many roots do Maxillary Molars have? |
|
| How many roots do Mandibular Molars have? |
|
| T/F: The potential for breakdown of the periodontium is directly
related to tooth form and function. |
