Special Health Care Skills Flashcards
What is odontology?
study of the anatomy, diseases, and growth of the teeth
What are dentitions?
sets of teeth (a primary / deciduous and permanent/succedaneous)
What are teeth buds? How do little teeth form?
44 teeth buds at birth, these buds erupt into teeth
when a child is 2-3 years old, all 20 primary teeth erupt, these erupt to form permanent teeth
What are the four main sections of the tooth?
crown, root, cervix, apex
Is the crown visible in the mouth? What is protecting it?
CROWN: tooth visible in the mouth, protected by enamel
Where is the root located? Is it visible? What does it do?
ROOT: tooth below gingiva (gums), not visible, anchors the teeth in the jaw
What is the cervix?
neck, area where enamel (crown) meets cementum (root)
What is the apex?
tip of the root of the teeth, contains an opening called the apical foramen (nerves and blood vessels enter through tooth)
What four tissues are each tooth made out of?
enamel, cementum, dentin, pulp
What is enamel?
the hardest tissue in the body, covers the outside of the crown, calcium & phosphorus
What is cementum?
hard, bonelike tissue that covers the outside of the root
What is dentin?
makes up the main bulk of the tooth, under cementum and enamel, living tissue
What is pulp?
soft tissue inside, made up of blood vessels and nerves
What is periodontium?
structures that support and structure the teeth
What is the alveolar process?
bone tissue of the maxilla and mandible, contains sockets for each tooth
What is the periodontal ligament?
suspends the teeth in the sockets
What is the gingiva?
made of epithelial covered with mucus, cover the alveolar process
What are the four main types of teeth?
incisors, cuspids (canines to tear food), bicuspids (premolars), molars (largest and strongest teeth))
How many maxillary (upper) and mandibular (down) primary/deciduous teeth are there?
10 of both
Are there bicuspids in premolars?
NO.
What is the Universal/National Numbering System?
abbreviated form for identifying the teeth
How does the UNS work for primary teeth?
teeth identified by A to T (maxillary is A - J and mandibular is T - K)
AB________ IJ
TS _________ LK
How does the UNS work for secondary teeth?
1________16
32_________17
1-8: maxillary right
9-16: maxillary left
17-24: mandibular left
25-32: mandibular right
How does the Federation Dentaire International System work for secondary teeth?
maxillary right: 1
maxillary left: 2
mandibular left: 3
maxillary right: 4
(molars start at 8, incisors at 1 for every quadrant)
