White and Brown spots in your teeth!! How is it managed?/ Dental Fluorosis..

FLUOROSIS

In general fluoride is a caries preventive agent
Fluoride is an electro-negative element acts similar to a double edged sword.
The reason is when the availability increases beyond adequate requirement results in toxicity.
This concept also suits for FLUORIDE intake.

WHAT IS FLUOROSIS?


Fluorosis is a developmental disturbance of enamel occurs due to excessive fluoride concentration over the ameloblasts (enamel forming cell) during formation.
The fluorosis causes changes in enamel and dentinal structures and also in fibroblasts cells that is necessary for gain of attachment .
Fluorosis involving the entire dentition

HOW IT WILL BE??

The fluorosed teeth severity ranges from white opacities in mild forms to severe brown pitted forms.
The severity increases only when  the exposure occurs during ameloblasts secretion and maturation.

WHAT ARE ALL THE CHANGE SEEN IN NORMAL VS FLUOROSED TEETH????

Fluorosis creates  a displeasing effect of the dentition particularly anteriors.
In fluorosed teeth  there is a greater hypo-mineralized  area in the subsurface region and also because of these increased porosities there will be lowering of the teeth demineralization resistance .
The inner dentinal layer also gets effected in severe cases  results in increased formation of certain lines(incremental lines) and their exposure leads to mechanical damage.
Hence the tooth will be more prone to decay.

HOW THE FLUOROSED TEETH GETS CORRECTED??

After management

There are different managements available for treating fluorosis.
  • Bleaching agents
  • Veneers (composite / porcelain)
  • Full coverage crowns
  • Combination technique includes Micro-abrasion,remineralizing paste, Home bleaching.

BLEACHING AGENTS:

Bleaching agents uses hydrogen peroxide(3.5%) or carbamide peroxide(10%).Most commonly used Mcinnes bleaching.
Soft tissue protection is done by your Dentist  to prevent any injury.
These agents remove the surface stains readily and sometimes causes tooth sensitivity .
To overcome tooth sensitivity , addition of potassium nitrate containing tooth paste throughout the bleaching therapy aids in desensitization.
ADVANTAGES:simple,low cost,safe to use in young permanent teeth,non-invasive technique.

VENEERS:

Veneers are tooth colored shell like material placed over the teeth after a mild preparation.
These  laminateveneers made of composite or porcelain.
Direct layering of composites can be done in single visit.

CROWNS:
In certain people the full coverage crowns can be given .
Using ceramic like material after a complete preparation all over the tooth .

MICRO-ABRASION:
Micro-abrasion uses acidic and abrasive agents (37% phosphoric acid and pumice mixture)
This technique is well suited for surface opacities whereas those inside the tooth structure well treated by bleaching agents.

COMBINATION TECHNIQUE:

It includes the combination of micro-abrasion,remineralizing paste and home bleaching techniques.
In this procedure the 0.2mm of minimal tooth structure reduced which is affected then the aplication of  remineralizing paste should be done.
In home technique involves the night bleaching tray with remineralizing paste placed into the mouth for certain weeks after the micro-abrasion during night.
For the application of remineralizing paste other than night bleaching ,should be placed all over the tooth surface and wait for dissolution for enhanced effect.
The reason behind is the components of the paste has remineralizing substances that absorbs hydrogen and increase the effect.
Remineralizing agents
