21
Q

Is the mesial marginal ridge normally larger or smaller than the distal marginal ridge?

A

mesial is normally longer

22
Q

What is the crest of curvature?

A

the greatest bulge on the buccal surface (or height of contour). This bulge is located on the cervical ridge of permanent molars (2nd)

23
Q

What are Mamelons?

A

are three small bulges or tubercles on the incisal edges of newly erupted incisors

24
Q

Can you easily find mamelons?

A

They are usually rubbed off on adult dentition

25
Q

What are perikymata?

A

are the numerous, minute horizontal ridges on the enamel of newly erupted permanent teeth

26
Q

What is an occlusal sulcus of a tooth?

A

a broad V-shaped depression or valley on the occlusal surface of each posterior teeth running mesiodeistally between buccal and lingual cusps

27
Q

fossa means

A

despression

28
Q

define groove

A

linear channel often found between cusps in the depth offthe sulcus and between ridges

29
Q

Purpose of a groove?

A

to serve as escape ways as the lower jaw moves, partially chewed food squirts out through the grooves towards the tongue and cheek

30
Q

developmental grooves

A

separate cusps and other major portions of a tooth formed from the developmental lobes

31
Q

central groove

A

on posterior teeth separating buccal from lingual cusps

32
Q

buccal groove

A

separates mesiobuccal and distobuccal cusps on mandibular molars

33
Q

mesiobuccal groove

A

separates mesiobuccal cusp from distobuccal cusp on mandibular molars

34
Q

distobuccal groove

A

separates distobuccal cusp from smallest distal cusp on mandibular molars

35
Q

lingual groove

A

between the mesiolingual and distolingual surface on mandibular molars, don’t typically extend into onto lingual surface on maxillary molars

36
Q

buccal groove

A

between mesiobuccal and distobuccal cusps that does not normally extend onto the buccal surface on maxillary molars

37
Q

supplemental grooves

A

are additional occlusal grooves that are NOT developmental. Not normally given a specific name because they do not occur in same areas of same teeth

38
Q

mesial and distal fossa

A

are shallow depressions on posterior teeth within the occlusal table

39
Q

pit

A

is at the depth of a fossa where teh central groove joins the fossa grooves

40
Q

distobuccal developmental groove

A

runs toward the distobuccal line angle of the tooth

41
Q

Where would you find central fossa?

A

on most 3-cusped premolars and molars

42
Q

lingual fossa is found where?

A

on anterior teeth, its shallow and broad located on the lingual surface

43
Q

define caries

A

tooth decay

44
Q

what is the proper name for tooth decay aka cavities?

A

caries

45
Q

Where are the ‘carious pits and fissures’ most likely to be located?

A

1) depth of deep grooves and pits on occlusal surface of posterior teeth
2) i buccal grooves that extend onto the buccal surface on mandibular molars
3) in lingual grooves that extend onto the lingual surface of maxillary molars
4) on the lingual surface of maxillary incisors where the lingual fossa joins the cingulum

46
Q

root trunk

A

is like a trunk base, is partof the root of a multirooted molar or 2-rooted premolar next to the cementoenamel junction

47
Q

furcation

A

is the place on a multirooted tooth where the root trunk divides into separate roots

48
Q

Furcation: difference between bifurcation and trifurcation?

A 
bifurcation= two rooted teeth
trifurcation= 3 rooted teeth
49
Q

What is a furcal region?

A

it is the region or space between two or more roots, found apical to where the roots divide off the root trunk

50
Q

In general, the amount of curvature is greater or lesser on the mesial surface than on a distal surface of the same tooth

A

greater

51
Q

What tooth has the greatest amount of mesial curvature?

A

central incisors
