surface of a posterior tooth.
●● Cusp
Answer: Found on the incisal edges of canines,
●● Cusp
Answer: a premolar usually has two of these on the buccal and lingual
surfaces.Mandibular second premolar may sometimes have three of
these.
●● Cusp Of Carabelli
Answer: Only found on the maxillary first molars
●● Cusp of Carabelli
Answer: only found on tooth #3 and #14
,●● Cusp of Carabelli
Answer: The fifth cusp, located on the mesial-lingual surface of many
maxillary first molars.
●● Cusp
Answer: Maxillary first and second molars and mandibular second
molars usually have four of these
●● Fossa
Answer: irregular depressions or concavities on the surface of anterior
and posterior teeth
●● Central Fossa
Answer: the depression or concavity found in the central portion of the
occlusal surface of molars
●● Ridge
Answer: The linear elevation on the surface of a tooth.
●● Marginal Ridge
Answer: The rounded boarder of enamel that forms the mesial and distal
boundaries of the occlusal surface of molars and premolars
,●● Marginal Ridge
Answer: the mesial and distal boundaries of the lingual surfaces of
incisors and cuspids.
●● Triangular Ridge
Answer: a ridge on a molar or premolar that descends from the tips of
the cusp towards the central part of the occlusal surface.
●● Transverse Ridge
Answer: the ridge formed by two triangular ridges that extend across the
surface of posterior teeth.
●● Oblique Ridge
Answer: Ridge crossing the occlusal surface of only maxillary molars in
an oblique direction
●● How many major fossa's are there
Answer: 4
lingual Fossa
Central Fossa
Mesial and Distal triangular fossa
●● Lingual Fossa
, Answer: depression or concavity found on the lingual surface of
mandibular and maxillary incisors located between the mesial and distal
marginal ridges
●● Triangular Fossa
Answer: located on the occlusal surface of the molars and premolars
distal to the mesial marginal ridge and mesial to the distal marginal ridge
●● Triangular Fossa
Answer: are always bordered by three developmental ridges one of
which is the marginal ridge named according by there location
●● Developmental Grooves
Answer: major grooves or lines between the ridges of a tooth named
according to there location
●● Supplemental groove
Answer: grooves that are less distinct, shallow linear depression on the
surface of teeth and are supplemental to developmental grooves , do not
mark he junction on primary parts of a tooth
●● Spillway
Answer: a shallow depression adjacent to a developmental groove
located on the occlusal surface of posterior teeth, originating in the
