Unit 305 - Oral Health Advice Flashcards
BPE score 0
healthy gums, no bleeding
BPE score 1
bleeding when probing, no calculus or defective margins
BPE score 2
calculus or plaque
BPE score 3
black band visible in deepest pocket
BPE score 4
black band not visible in pocket
a thin, transparent, sticky, soft film present on the teeth
plaque
inflammation of the gum
gingivitus
calcified plaque is also known as
tartar/calculus
streptococcus mutans is also known as
dental caries
the process of the enzymes in saliva repairing enamel
remineralisation
a healthy periodontium is described as
pink, tight gingival cuff, no deeper than 2mm pockets
‘acid attacks’ on the teeth cause
demineralisation
Stephan’s Curve defines the mouth being neutral at a PH of
7
the salivary gland located underneath the tongue at the back is called
the sub-mandibular gland
the salivary gland located at the front of the mouth underneath the tongue is called
the sublingual gland
the largest salivary gland in the mouth, located in the cheek, is called
the parotid gland
fluid containing water, inorganic ions (such as calcium, phosphates and digestive enzymes, antibodies, white blood cells)
saliva
reduced salivary flow is also known as
xerostomia (dry mouth)
xerostomia can be caused by (4)
dehydration, autoimmune disorder, age or certain drugs
too much saliva is known as
ptyalism
ptyalism can be caused by
pregnancy or parkinsons disease
two ways fluoride is introduced in to the body
topically or systemically
a tooth displaying too much white enamel with a mottled effect
enamel fluorosis
grinding of teeth
bruxism
chewing
mastication
worn occlusal surfaces of the teeth is known as
attrition
wearing at the neck of the tooth is known as
abrasion
abrasion can be restored with
fillings or early fluoride application
bad breath is also known as
halitosis
acid reflux or a high acid diet can lead to
erosion
white lesions on the soft tissues are known as
leukoplakia
made up of inorganic crystals arranged as prisms
enamel
part of the tooth which cannot experience sensitivity as there are no nerves or blood vessels
enamel
hydroxyapatite
main crystals in enamel
part of the tooth which cannot grow or repair as it is not a living tissue
enamel
part of the tooth which exchanges minerals with the oral cavity (such as fluoride)
enamel
the junction where enamel meets dentine
amelodentinal junction (ADJ)
ameloblast cells at the ADJ form
enamel
enamel is thickest ____ and most thinnest _____
enamel is thickest occlusally and thinnest at the neck
part of the tooth which is a living tissue and can transit sensitivity
dentine
part of the tooth which is yellowish and elastic
dentine
sensory endings from the cells forming dentine are known as
fibrils (found in hollow tubules)
formed by ondontoblast cells
dentine
ondontoblast cells are found
at the edge of the pulp chamber
dentine formed as part of the aging process
secondary dentine
caries produce quicker in dentine because
because of hollow tubes within
soft tissue enclosed by dentine
pulp
sensory nerves and blood vessels enter the pulp at
at the apical foramen
the pulp chamber is made more narrow by the formation of
secondary dentine
bone in the mouth which supports the teeth
alveolar bone
when a tooth is extracted the alveolar bone..
..gradually resorbs and disappears
the hard compact bone on the outer surface of the alveolar bone
lamina dura
the spongelike bone that blood vessels and nerves run through
cancellous bone
soft tissues surrounding the alveolar bone are called
alveolar mucosa
destruction of the alveolar bone occurs in
perio disease
____ attaches teeth to the alveolar bone
periodontal ligament
made up of protein called collagen
periodontal ligament
“shock absorber” for biting
periodontal ligament
healthy gingavae is (in appearance)
light pink with stippled surface
healthy gingavae has no more than a _mm gingival crevice
2mm
inflamed, red, shiny gingavae indicates
gingitivis
bacterial disease whereby mineralised tissues are demineralised to form cavities
dental caries (decay)
streptococcus mutans is also known as
dental caries
these produce weak organic acids as a by-product (eg. lactic acid)
dental caries
NMES stands for
non milk extrinsic sugars (added sugars)
sucrose, glucose and dextrose are examples of
NMES (non milk extrinsic sugars)
fructose in fruit is classed as
an intrinsic sugar
lactose is classed as
a milk extrinsic sugar
