Oral Hygiene Products Flashcards
The visible part that extends above the gum (gingiva)
Crown
Sits in the upper or lower jawbone, remains invisible until recession of the gum exposes some root surfaces
Root
Boundary between root and crown
Neck
The mucosa that covers the upper and lower jaws, and surrounds the neck of the teeth.
Gingiva
- Soft connective tissue containing nerves and blood vessels from the root canal
- Dentin forming cells are found in this area
Dental Cavity or Pulp Cavity
3 Substance for a Tooth to resemble Bone:
Enamel
Dentin
Cementum
- White outer part
- Hardest substance in the human body preventing the tooth from wearing away under pressure of chewing
- Contains Calcium Hydroxyapatite which starts to dissolve below pH 5.5
Enamel
What impacts enamel hardness and strength
Demineralization & Remineralization
- Yellowish bone-like layer surrounding the dental cavity which forms the largest portion of the tooth.
- More porous, softer, more sensitive, and more susceptible to decay and wear if exposed.
- Less dense than enamel
Dentin
- Special connective tissue that covers the dentin at the root.
- Binds the roots of the teeth firmly to the gums and jawbone, and anchored in the jaw by the periodontal ligament.
Cementum
Components of saliva that acts as a buffer
Carbonic Acid & Bicarbonate
[TRUE OR FALSE] Acidulated Phosphate Fluoride promotes remineralization and prevents demineralization.
True
Sticky, colorless film of bacteria and sugars that form on the teeth
Plaque
- Disease resulting in the breakdown and destruction of the enamel due to demineralization
- Tiny Bone Holes on the surface of the teeth
Dental Caries or Tooth Decay
- Hardened plaque that causes yellowish-brown discoloration to the teeth.
- Calcified plaque which can form beneath the gums. It can irritate the gum tissues
Dental Calculus or Tartar
- Main cause of teeth loss
- Infection of the gums that can progress to affect bone that surround and support the teeth
Gum Disease
Brief episodes of sharp well-localized pain when subjected to various stimuli.
Nangingilo
Tooth Sensitivity
- Intrinsic Discoloration
- Spots or small area on the teeth contrasting with the rest of teeth color.
Dental Stains or Teeth Discoloration
Oral malodor, due to food, alcohol, tobacco, or disease
Bad Breath or Halitosis
Normal pH of saliva
6.7 - 7.4
[TRUE OR FALSE] Only children below 8 years old can develop fluorosis
TRUE
Does not flow out of an open container if no pressure is used and can “stand up” on the brush
Bingham Plastic
Stays viscous until force is applicable; viscosity reverts to original high value when shear force is removed.
Pseudoplastic (Shear Thinning)
It is less soluble than hydroxyapatite. Which is necessary for remineralization.
Fluorohydroxyapatite
Allowable total fluoride for 2 yrs and above
850 - 1150 ppm
Allowable total fluoride for 6 yrs and above
1500 ppm
