– makes up the crown of the tooth
ENAMEL
enamel is the – substance in the body
hardest
The enamel is called –, a crystal that is translucent
hydroxyapatite
DENTIN is – the enamel
beneath
makes up the core of the tooth
dentin
The root portion of the tooth is covered by a thin tissue called –.
CEMENTUM
The PERIODONTAL LIGAMENT attaches the tooth to the – from the cementum surface
alveolar bone
smooth surfaces
Buccal, lingual and biting surfaces
Surfaces between the teeth
interproximal surfaces
target zone for cleaning
gingival
Methods of brushing developed because of materials that were –
available at the time
earliest brushes were made from
natural pig bristle
Bass method: Place the toothbrush on the – at an angle of 45°
gums
always start brushing at the –
back
prefer – brush head size
small
replace brush every –
3 months
Alternate tufts rotate in opposite directions
interplak
Brush head rotates in circular direction
rotadent
Brush head oscillates, one direction then opposite direction
Braun Oral-B
Brush head moves side-to-side laterally
sonicare
disadvantage of interplak’s alternating tuft rotation
gears can get clogged
The review of trials found that only – is better than manual toothbrushes at removing plaque and reducing gum inflammation, and is no more likely to cause injury to gums.
rotation oscillation (where heads rotate in one direction and then the other)
DSMPT
Distal surface on most posterior tooth
DSMPT also refers to interproximal surface adjacent to an–
edentulous (removable partial denture)
END tufted brushes Excellent for edentulous side (mesial & distal) of an abutment tooth, or –
isolated single tooth
– brushes for Distal surface of most posterior tooth
End tufted brushes
End tufted brushes Used for applying antimicrobial rinse, ACP paste or – paste to specific tooth surface
Rx fluoride
use an end tufted brush by – the area
sweeping
At one time, researchers thought rubber tip “stimulator” could – on the inner surface of the gingival sulcus
stimulate keratinized tissue
rubber tip “stimulator” Most –way to clean along tooth-gingival sulcus area
gentle
use rubber tip stimulator on Mesial & distal surfaces adjacent to –
extraction site
rubber tip stimulator is Especially good when tissue is – (eg., tooth brush abrasion)
irritated due to trauma
use Following periodontal surgery
rubber tip stimulator
use rubber tip stimulator Along –(eg., ortho band)
molar banded teeth
rubber tip stimulator MOST GENTLE WAY TO CLEAN ALONG the –
TOOTH-GINGIVAL INTERPHASE
rubber tip stimulator is – on every tooth
not intended to be used
use for furcation areas
rubber tip stimulator
rubber tip stimulator for – contoured crowns
overly
rubber tip stimulator are used for – areas of fixed bridges
embrasure
rubber tip stimulator for – of an orthodontically bander tooth
gingival margin
use a – motion for rubber tip stimulator
dragging
use – brush for single/double isolated teeth
sulcus
use sulcus brush for – arch
partially endentulous
use sulcus brush for – gingival margin
irregularly contoured
Areas of teeth most severely affected by gingivitis, going from most to least: interproximal
upper > lower
Areas of teeth most severely affected by gingivitis, going from most to least: buccal
upper > lower
Areas of teeth most severely affected by gingivitis, going from most to least: lingual
lower > upper
– of embrasure determines what interproximal tool used
size
Floss, wooden cleaners, Soft-Picks, floss threader
Type 1 embrasure
Interdental CYLINDRICAL brush, possibly “superfloss”, Go-between, & maybe the Go-Between Ultra
Type 2 embrasure
Interdental tapering brush, “superfloss”
Type 3 embrasure
