38
Enamel covers the portion of the tooth known as the ____ and cementum covers the portion of the tooth know as the ____
Anatomic crown, anatomic root
39
the relatively white, protective external surface layer of the anatomic crown. It is highly calcified or mineralized and is the hardest substance in the body. Its mineral content is 95% calcium hydroxyapatite
Enamel
40
the dull yellow external layer of the anatomic root. The _______ is very thin, especially next to the part of the root where the crown joins with the root
Cementum
41
junction between the enamel covering the anatomic crown and the cementum covering the anatomic root.
Cementoenamel junction
42
Another name for the CEJ, surrounds the neck of the cervix.
Cervical Line
43
hard yellowish tissue underlying the enamel and cementum, and makes up the bulk of the inner portion of each tooth crown and root.
Dentin
44
the inner surface of the enamel where enamel joins dentin. This junction can be best seen on a radiograph
dentinoenamel junction DEJ
45
he inner surface of cementum where cementum joins dentin
cementodentinal junction
46
soft, nonmineralized connective tissue containing a rich supply of blood vessels and nerves located in the cavity or space in the center of the crown and root called the pulp cavity. Formative, sensory, nutrative
Pulp
47
The pulp cavity has a coronal portion toward the crown
pulp chamber
48
Portion of the pulp that is within the roots
Pulp/root canal
49
Hole that nears the the root tip.Nerve and blood vessels enter the pulp canals.
Apical Foramin
50
Which tooth junctions are NOT normally visible on a handheld intact tooth?
Dentinoenamel dentinocemental dentinopulpal
51
Which mineralized tissue is the hardest?
Enamel
52
What tissue forms the outer boundary of almost all of a pulp chamber?
Dentin
53
Which of the following is (are) functions of the pulp?
-Sense pain -Provide nutrition to dentin -Produce new dentin
54
the supporting tissues of the teeth in the mouth, including surrounding alveolar bone, the gingiva, the periodontal ligament, and the outer, cementum layer of the tooth roots
Periodontum
55
the portion of the upper (maxillary) or lower (mandibular) bones that surrounds the roots of the teeth
Alveolar bone
56
Part of the soft tissue in the mouth that covers the alveolar bone of the jaws and is the only part of the periodontium that is visible in a healthy mouth.
Gingiva
57
Gingiva that is firmly bound to the underlying alveolar bone and is called
attached gingiva
58
Marginal gingiva, which is a collar of thin gingiva that surrounds each tooth and, in health, adapts to the tooth but provides access i
Free gingiva
59
space between the free gingiva and the tooth,
Gingival Sulcus
60
the edge of the gingiva closest to the biting or chewing surfaces of the teeth
Gingival margin
61
tooth is in the mouth, the amount of the tooth that is visible in the oral cavity (i.e., not covered with gingiva) `
clinical crown
62
the portion of the tooth that is not visible since it is covered with gingiva
Clinical Root
63
Compare the clinical crown & root of a partially erupted tooth of a 10 year old compared to the anatomic crown
Clinical crown of 10 year old is much shorter than anatomic crown. The clinical root is is much longer than the anatomic root since more is covered by gingiva.
64
Which statement(s) is (are) likely to be true on a person with a barely erupted tooth 9?
The clinical crown is smaller than the anatomic crown. The clinical root is larger than the anatomic root.
65
Which statement(s) is (are) true regarding a tooth on a person who has lost most of the bone and gingiva surrounding the tooth?
Clinical crown longer than anatomical Clinical root is smaller than anatomic.
66
Structures of periodontium
-Alveolar bone -PDL -Gingival margin -Attached gingiva
67
The periodontal ligament attaches the alveolar bone to what tooth tissue?
Cementum
