- what is the succadaneous tooth for primary tooth 7 1? - -lower left central
incisors
- what is the succadaneous tooth for primary tooth 6 2? - -upper left lateral
incisor
- what is the succadaneous tooth for primary tooth 7 5? - -lower left 2nd
molar
- what is the succadaneous tooth for primary tooth 5 4? - -upper right 1st
molar
- the relationship between the maxillary and mandibular teeth when they
are in fully closed positioned is called? - -occlusion
- how are the permanent teeth number in the universal/national system? - -
1-32
- how many molars are in the permanent dentition - -12
, - 1. what are the two surfaces that are proximal surface? - -mesial and
distal surface
- Which permanent teeth are non- succadaneous? - -Molars (6-7-8)
- What tooth number is the adult mandibular left 1st molar? - -6
- What are the characteristic of primary dentition? - -Relatively large pulp
chambers
- Which premolar has 2 bifurcated roots? - -Maxillary first premolar
- The permanent dentition period begins at about 12 yrs of age when? - -the
last primary tooth is loss
- What is the standard for normal occlusion? - -Centric occlusion
- The tooth surface closes to the tongue on both anterior and posterior teeth
is the? - -Lingual surface
- Are there 4 premolars in the primary dentition? - -no
- Which tooth number system is used most often in Canada? - -International
standard organization system
- The crown of the tooth that is divided crosswise with the division being
parallel to the occlusal or incisal surface of the tooth has what division? - -
Occlusal third, middle third, and cervical
- Define the term contact area what are the 3 purposes of a proper contact
area between teeth(4pts) - -Contact area is the area of the mesial or distal
surface of a tooth that touches the tooth next to it in the same arch. the
purposes are: 1.prevents food from being trapped between the teeth 2.
Stabilizes the arches 3. Protects the interproximal gingival tissues from
trauma during chewing.
- Describe angles classification of malocclusion regarding the position of the
molars and cuspids(6pts) (molar #6 maxillary guide) - -Class 1- normal
relationship with molars, the anterior teeth are malpositioned
Class 2-distoclusion (overbite)occurs the mandible is in an abnormal distal
relationship to the maxilla
Class 3-mesioclusion(underbite) occurs when the body of the mandible is in
an abnormal mesial relationship to the maxilla.
- the upper teeth are set in? - -maxilla
