UCLA BDP Midterm UPDATED Exam
Questions and CORRECT Answers
types of teeth - CORRECT ANSWER - incisors (central, lateral), canines, premolars (1st
and 2nd), molars (1st, 2nd, 3rd)
dental quadrants - CORRECT ANSWER - maxillary right, maxillary left, mandibular
right, mandibular left
- four equal sections of the mouth, divided from the midline, and used by dentists to describe the
location of teeth
- "right" and "left" are in the perspective of the patient
anterior teeth - CORRECT ANSWER - - front teeth in the aesthetic area of the mouth,
including INCISORS AND CANINES
- primarily for cutting and tearing food
posterior teeth - CORRECT ANSWER - - back teeth in the mouth, including
PREMOLARS AND MOLARS
- primarily for grinding and crushing food during the chewing process
tooth crown - CORRECT ANSWER - - visible part of a tooth that you can see in the
mouth; part used for biting and chewing food
- primarily composed of enamel, which is the hardest substance in the human body
tooth root - CORRECT ANSWER - - part of the tooth that is below the gumline and holds
the tooth securely in the jawbone
- the surface is covered by CEMENTUM, a hard tissue that helps anchor the tooth to the jawbone
dentin - CORRECT ANSWER - - middle layer that makes up the main structure of a tooth
,- not as hard and provides support to the enamel while also transmitting sensation, such as
temperature changes and pressure, to the pulp of the tooth
universal numbering system - CORRECT ANSWER - - permanent teeth: numbered from 1
to 32
- upper right --> upper left (1-16) --> lower left (17-32) --> lower right
- most commonly used in the US
palmer notation - CORRECT ANSWER - - quadrant based
- start counting from the midline
federation dentaire international (FDI) - CORRECT ANSWER - - two-digit system
- 1st number = quadrant
1=UR, 2=UL, 3=LL, 4=LR
- 2nd number = tooth within quadrant
1-8
- most commonly used worldwide
(facial) labial surface - CORRECT ANSWER - surface of tooth next to the lips
(facial) buccal surface - CORRECT ANSWER - surface of tooth next to the cheeks
lingual surface - CORRECT ANSWER - - surface of tooth next to the tongue
- an alternative term for maxillary teeth is "palatal surface"
(proximal) distal surface - CORRECT ANSWER - side of the tooth away from the midline
(proximal) mesial surface - CORRECT ANSWER - side of the tooth toward the midline
, occlusal surface - CORRECT ANSWER - chewing or biting surface of posterior teeth
incisal surface - CORRECT ANSWER - chewing surface of anterior teeth
periodontium - CORRECT ANSWER - a complex structure composed of the tissues that
surround and support the teeth
anatomy of the periodontium - CORRECT ANSWER - gingiva, cementum, periodontal
ligament, alveolar bone
gingiva - CORRECT ANSWER - - covers the alveolar bone and the tooth root
- protects teeth and underlying bone against mechanical and microbial damage
periodontal ligament (PDL) - CORRECT ANSWER - - complex network of fibers
- surrounds the tooth root
- connects cementum to alveolar bone
periodontal probe - CORRECT ANSWER - - measures pocket depth
- colors in 3mm increments
universal curette - CORRECT ANSWER - - removes calculus and plaque supragingivaly
and subgingivaly
- can be used on all surfaces of the teeth
supragingival - CORRECT ANSWER - above the gingiva
subgingival - CORRECT ANSWER - below the gingiva
