Tooth Morphology Flashcards
During lateral movement of the jaw, this tooth acts as a guidepost with its antagonist
Upper Canine
In this tooth the distal fossa is generally larger than the mesial fossa
Lower second premolar
This tooth has a pit on its buccal surface whihc is at increased risk of caries
Lower First Premolar
This too has the mesial surface more deeply gooved than the distal and shows a concavity in the cervical region
Upper First Premolar
Crown set an angle to root, producing convex labial profile drom cusp to apex. Often has enamel exteding furhter apically on labial side than on lingual side
Lower Canine
In this tooth, the lingual cusp is displaced distally. A small groove often runs from the mesial pit on to the mesiolingal surface
Lower First Premolar
The crown is by far the largest of the 4 incisors. Being almost as wide as it is long
Upper Central
Usually, this tooth only has four cusps of similar size, The occlusal surface is almost square
Lower Second Permanent Molar
This tooth is diamond shaped, with the longer diagonal extednign from the mesio-buccal to the disto-palatal cusp
Upper First Permanent Molar
The cusps are similar in width and height, due to reduction in size of the buccal cusp
Upper First Premolar
The lingual surface has two pronounced marginal ridges. Sometimes, where the ridges meet at the cervix, they enclose a depression or fossa
Upper Lateral Incisor
Looking at the crown from the mesial and distal aspects, it appears as wedged shaped and leans lingually. There are faint marginal ridges and a small cingulum
Lower Lateral Incisor
The disto-palatal cusp is greatly reduced, and may be asbent. Thus making the shape of the crown more triangular
Upper Second Permanent Molar
