8. What is preventive dental material?
Preventive is derived from the word preventio it means
forestalling to act before hand hider.
Preventive dental materials are tools and products used
to prevent cavities and tooth decay.
9. Why are they used?
To prevent caries, or pathogen.
To prevent tooth decay.
To prevent disease and injury.
10. Types of preventive dental material
Invasive dental material : are material that are used after the
caries for treatment in order to preventive the caries which are
damaged the root cannel( it prevents RTC), e.g. pit and fissure
11. What are dental sealant?
• Are thin liquid coating painted on to the chewing surface of your
(premolars and molars).
• Ones applied, dentist cures and hardens the sealant to shield and
protect your teeth from harmful cavity causing bacteria.
13. Dental sealant made up
Manufactures uses a couple different materials to make sealants,
including medical grade:-
1. Resing (plants and synthesis).
2. Glass ionomers (glass powder and combined with water soluble
15. Resin-based sealants
May or may not contain filler particles or fluorides.
The setting reaction can be automatic(auto-polymerised) or ( light-
Retention rates 2%-80% better than the GIC sealants.
Low viscosity resin-based.
17. Glass ionomer sealant
Can adheres directly to tooth substance.
Release fluoride over time.
Less sensitive to moisture contamination than resin-based
Retention is a major problem with GIC sealant.
Sealants should not be placed on partially erupted (i.e., once there
is gingival tissue on the crown).
Teeth with cavitation or caries of the dentin.
Wide and self cleansable pit and fissure.
Pit and fissure that have remained carious free for 4 year or longer.
• Non invasive dental material: are materials that are used before
caries for protection such as tooth pastes with fluorides, mouth
25. Tooth paste and its functions
Component and composition of tooth pastes
Colloidal binding agent: sodium agnate methyl cellulose.
And its function prevent separation of component in the tube during the
Humectants: ( dilutes) glycenin and its function reducing water loss by
Preservatives: used inhibited bacteria growth.
DETERGENTS: major contributor to teeth cleaning process.
Should be tasteless, nontoxic, non-irritant, produce large volume
of non gigging foam.
Sodium lauryl sulfate ( SLS).
Sodium lauryl sarcosinate.
Anticaries active: fluoride ions reduce the incidence of carious
lesion by reducing the acid solubility of tooth enamel.
Extended consumption of large volumes of fluoridated toothpaste
can result in fluorosis.
Fluoridated toothpaste can be either acutely toxic if swallowed in
Although in several studies whitening toothpaste show improve
tooth color they have side effect.
The most significant one is enamel and dentin abrasion which in
turn leads to increased tooth sensitivity.
37. What does fluoride do?
Every day, your enamel ( the protective outer layer of your tooth) gains and
loss minerals. You loss minerals when acids –formed from bacteria, plaque
and sugars in your mouth- attack your enamel( this process is called
You gain minerals like fluoride, calcium and phosphate when you consume
food and water that contain.
You can also get purchase fluoride tooth pastes and mouth wash( this
process is called re mineralization).
A dentist can also applied fluoride to your teeth in form of:-
1) Foam:- which they will dispense into a custom tray, than the
place over your teeth.
• 3. Gel:- which they will either paint on your teeth or dispense in
41. Which age is fluoride intake most
Infant and children between age of 6 month up to 16years need
an appropriate amount of fluoride.
42. Does adult benefit from fluoride?
Yes, adults can benefit from fluoride.
If you have:-
Dry mouth:- certain medications( allergic medication)
side effect of some health care condition.
Gum disease: which exposes your teeth and gums to bacteria
and increase your risk of decay teeth .
45. Mouth washes and its function
1. Active agent –anti-caries, antimicrobial.
2. Solution - water, alcohol-preservative.
Children younger than the age of 6 year should not use mouth wash unless
directed by a dentist, because they may swallow.
47. Tooth brushes
Tooth brushes are made of natural or nylon bristles.
Nylon bristles are better than natural bristles, for the remain straight, stiff for long time and dry out
Types of nylon bristles :-
49. Hard tooth brushes
1. Firm or hard bristles can acutely wear away at your tooth
enamel ( the teeth‘s protective layer ), which is something that can not
be replaced. Damaged tooth Enamel can result I n more bacteria sticking to
your teeth which can result in decay. Hard tooth brushes can also damages
your gums. Causing the gum line to recede, resulting in your teeth
becoming more vulnerable to decay.
52. Soft tooth brushes
Soft brushes should be used for prevention abrasive wear of tooth
structure: also, soft tooth -brushes are actually more affective at
removing food and plaque build up than hard bristles tooth brushes,
and they are gentler you the teeth and gums. Soft-bristled brushes
are best for removing plaque and debris from your teeth and along the
gum line as they are not abrasive enough to cause erosion to the
64. Dental floss and its function
forms of dental floss
Polishing of the tooth surface during removal of plaque and debris.
Removal of adherent plaque and food debris from interproximal.
67. Interdental brushes
They are cone shaped or cylindrical brushes made of bristles
mounted on a handle.
68. Non toxic for patient dentist and staff.
Non irritating to oral cavity and tooth tissues.
