triangular ridge - ANSWER ✓ An elevation of enamel that descends from the cusp
into the middle area of the occlusal surface
transverse ridge - ANSWER ✓ The union of two triangular ridges that produces
one ridge across the occlusal surface
oblique ridge - ANSWER ✓ Transverse ridge that crosses occlusal table obliquely
from mesiolingual to distobuccal on most maxillary molars
Cingulum - ANSWER ✓ Raised, rounded area on the cervical third of the lingual
surface
Mamelons - ANSWER ✓ three bulges on the incisal edge of a newly erupted
central incisor
developmental groove - ANSWER ✓ A groove formed by the union of two lobes
during development of the crown
Central groove - ANSWER ✓ Most prominent developmental groove on the
posterior teeth
supplemental groove - ANSWER ✓ Shallow, linear groove in the enamel of a
tooth. It differs from a developmental groove in that it does not mark the junction
of lobes; it is a secondary, or smaller, groove.
Fossa - ANSWER ✓ shallow depression
, gingival sulcus - ANSWER ✓ space between the free gingiva and the tooth
surface
interdental papilla - ANSWER ✓ sharp, pointed projection of gingival in between
the teeth
gingival margin - ANSWER ✓ The rolled border or crest of tissue surrounding the
crown portion of each tooth.
attached gingiva - ANSWER ✓ gingiva that tightly adheres to the bone around the
roots of the teeth
Periodontal Ligament (PDL) - ANSWER ✓ Ligament surrounding the teeth that
supports and attaches them to alveoli bony surface
Maxillary molars have how many roots? - ANSWER ✓ three
Mandibular molars have how many roots? - ANSWER ✓ 2 roots (mesial and
distal; root trunk is shorter than root trunk of maxillary molars)
Anodontia - ANSWER ✓ congenital absence of teeth
Hypodontia - ANSWER ✓ partial anodontia; the lack of one or more teeth
Supernumerary teeth - ANSWER ✓ Development of one or more extra teeth
Most common areas for 'extra teeth' - ANSWER ✓ Maxillary incisors, Maxillary
third molars, and Mandibular Premolar
Mesiodens - ANSWER ✓ Supernumerary tooth between two permanent maxillary
central incisors
Third Molar Malformations - ANSWER ✓ Maxillary third molars have the
greatest variation in crown shape
Peg Lateral Incisor - ANSWER ✓ when the laterals are smaller in size than
normal and are shaped like a peg
, Gemination (twinning) - ANSWER ✓ twin crown, but 1 root common pulp canal
twinning occurs more frequently in - ANSWER ✓ max. incisors or canines
fusion of teeth - ANSWER ✓ union of two independently developing primary or
secondary teeth
fusion always involves - ANSWER ✓ dentin
fusion is commonly found in - ANSWER ✓ mandibular anteriors
Shovel-shaped incisors are one of the most distinctive features of people from: -
ANSWER ✓ Asian, Indian, and Native American populations
Shovel-shaped incisors - ANSWER ✓ anterior teeth which on their lingual
(tongue) surface are concave with two raised edges that make them look like tiny
shovels
Hutchinson's Incisors result from - ANSWER ✓ mother passing syphilis to an
unborn child
Hutchinson's Incisors - ANSWER ✓ appear screwdriver shaped
Mulberry Molars- Congenital Syphilis - ANSWER ✓ Berry-like in shape on the
occlusal surfaces
Enamel hyperplasia - ANSWER ✓ increase of enamel tissue
Tuberculum - ANSWER ✓ extra lingual cusps
talon cusp - ANSWER ✓ accessory cusp that arises from the cingulum of an
incisor or canine
Tubercles on teeth - ANSWER ✓ small extra enamel projections
Microdontia - ANSWER ✓ abnormally small teeth
