MODULE 14 Flashcards
the anatomical area of teeth, usually covered by enamel
crown
the whole crown area above the neck, above the cementoenamel junction
anatomical crown
a portion of the anatomical crown that is visible or exposed in the oral cavity
clinical crown
part of the tooth between the root and the crown
the neck
the neck is also called as the
dental cervix
the __ is below the gingiva and is anchored to the bone
the root
the center portion of the root known as the
root canal
found below the cementoenamel junction and is covered with cementum.
anatomical root
portion of the anatomical root that is exposed/embedded in the bone
clinical root
the hardest and most mineralized substance of the body
enamel
the four major tissues that make up the tooth
enamel, dentin, cementum, and dental pulp
inorganic and organic material in enamel
96% inorganic, 4% water and organic material
the normal color of enamel
light yellow or grayish white
enamels primary mineral
hydroxyapatite
hydroxyapatite is a
crystalline calcium phosphate, primary inorganic component of the teeth
the substance between enamel or cementum and the pulp chamber
dentin
ang nag form sa dentin
odontoblasts
the formation of dentin is known as
dentinogenesis
dentin is made up of
70% inorganic 20% organic 10% water
microscopic channels in dentin called as
dentinal tubules
a layer of dentin produced after a root formation and continues to form with age
secondary dentin
layer of dentin created in response to stimulus, such as cavities and tooth wear
tertiary dentin
what is dentinal hypersensitivity
sharp pain in the tooth caused by exposed dentin and open dentinal tubules
a specialized bone like substance covering the root of a tooth.
cementum
cementum is made up of
45% inorganic, 33% organic 22% water
cementum is excreted by
cementoblasts
part of the tooth where the periodontal ligament attaches to
cementum
the central part of the tooth filled with soft connective tissue
dental pulp
This tissue contains blood vessels and nerves that enter the tooth from a hole at the apex of the root
dental pulp
portion of the dental pulp contained within the pulp chamber or crown cavity of the tooth.
coronal pulp
part of the dental pulp contained within the apical or root portion of the tooth.
radicular pulp
the specialized tissues that both surround and support the teeth
the periodontium
tissues of the periodontium
gingiva, cementum, periodontal ligaments, alveolar bone
the thickened ridge of bone that contains the tooth sockets (dental alveoli) on the jaw bones that hold teeth.
alveolar bone
curved part of each alveolar process on the jaw is called
alveolar arch
a region of compact bone adjacent to the periodontal ligament
lamina dura
alveolar bone is made up of
67% inorganic 33% organic
compact bone is also called as
cortical bone or cribriform plate
dense bone in which the bony matrix is solidly filled with organic ground subtance
compact bone
tiny spaces in the compact bone that contains osteocytes or bone cells
lacunae
the layer that directly surrounds the tooth sockets,
alveolar bone proper
the area of the bone that directly comes into contact with the root of a tooth
alveolar bone proper
highly vascularized and contains red bone marrow
trabecular bone (spongy bone)
what gives a trabecular bone is spongy appearance
trabeculae
a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within
periodontal ligaments
It forms the line where the cementum (that covers the root) meets the enamel.
dental cervix
