Classification of Fluorosis Stains on Tooth


Dental Fluorosis definition – It’s outlined because the Hypoplasia or Hypomineralization of the Teeth or Dentin of the teeth produced via Power Ingestion of over the top quantities of fluoride all the way through the duration of teeth building.

The age at which Fluorosis can have an effect on the growing tooth levels between – 22 months to 5-7 years of age.

In easy phrases, Dental Fluorosis is whitish, yellowish to brownish discoloration of tooth because of overexposure of growing everlasting tooth to fluoride. Most often Fluorosis isn’t destructive however only a beauty fear. Fluorosis is brought about via when the growing tooth are uncovered to fluoride all the way through growing levels – under 8 to ten years of age. Already erupted tooth can’t be suffering from extra publicity to fluoride.

What’s the Superb Fluoride ranges in Consuming water via Age:

  • Delivery to six months – No longer required

  • 6 months to a few years – 0.25 mg/day for <0.3 ppm

  • 3-6 years – 0.50 mg/day (<0.3 ppm) and zero.25 mg/day (0.3 to 0.6 ppm)

  • 6-16 years – 1 mg/day (<0.3 ppm) and zero.50 mg/day (0.3 to 0.6 ppm)

What’s the Superb quantity of Fluoride in Toothpaste for Youngsters:

  • 0.3 to 0.5 grams of Fluoride can also be swallowed whilst brushing
  • The utmost threshold for Fluorosis is 0.03 to 0.1 mg F/kg

There are 4 Indices which might be used measure Dental Fluorosis:

  • Deans Fluorosis Index
  • Group Fluorosis Index (CFI)
  • Enamel Floor Index of Fluorosis
  • Fluorosis Chance Index

Deans Fluorosis Index Classification- 

  1. Standard – Easy, shiny, light creamy-white translucent teeth floor
  2. Questionable – A couple of white flecks or white spots (Chalk like) often known as as Mottled Teeth
  3. Very Gentle – Small opaque, paper white spaces masking not up to 25% of the teeth floor
  4. Gentle – Opaque white spaces masking not up to 50% of the teeth floor
  5. Average – All teeth surfaces affected, marked put on on biting surfaces, brown stain is also provide
  6. Critical – All teeth surfaces affected, discrete or confluent pitting, brown stain provide

Group Fluorosis Index (CFI)-

This is a amendment of Deans Index the place a numerical price is given to every class, which comes in handy in comparative research. It’s accomplished at the foundation of the quantity and distribution of person ratings, a group index for dental Fluorosis (Fci) can also be calculated via the formulation. 

Fci = Sum of (selection of people) / selection of people tested

Enamel Floor Index of Fluorosis (TSIF)

It’s used to measure the superiority and Severity of Fluorosis which is very important to Public well being. This is regarded as to be extra delicate in figuring out mildest varieties of fluorosis as in comparison to Deans Index. This can be utilized in each number one and everlasting dentition. 

  • 0 – No proof of Fluorosis
  • 1 – Particular proof of Focal white spaces not up to one-third of teeth
  • 2 – White house a minimum of 1/3 however not up to 2/3
  • 3 – A minimum of 2/3 of visual floor 
  • 4 – Teeth staining along with any of the above
  • 5 – Discrete pitting w/o staining
  • 6 – Discrete pitting with staining 
  • 7 – Confluent pitting (fused), huge spaces of teeth is also affected or lacking

Fluorosis Chance Index

Utilized in Analytic research which is used to spot chance elements for fluorosis. It divides the buccal and occlusal surfaces of every teeth into 4 zones in line with the age at which calcification starts. 

  • Magnificence 1 – formation started in 1st 12 months of lifestyles
  • Magnificence 2 – formation started 3-6 years of lifestyles

Mechanism of Motion of Fluorosis:

As we all know Fluorosis is brought about because of extra consumption of Fluoride all the way through the developmental levels of teeth building. The supply of extra Fluoride can also be from any of the next resources – 

  • Extra Fluoride in Consuming water (Maximum not unusual)
  • Extra use of Fluoride toothpaste
  • Eating meals or beverages produced from fluoridated water
  • Extra use of Fluoride pills

Because of extra consumption of Fluoride ends up in injury of the secretory ameloblast leading to adjustments noticed at the Teeth floor. It ends up in porosity in Teeth because of both exchange in composition of Teeth matrix or because of a disturbance of the mobile processes all the way through the maturation of teeth. This is named as Mottled Teeth which is characterised via minute white flecks or yellow or brown spots or irregularly scattered over the skin of the teeth.

Mottled Teeth could also be Categorised via Al Alousi et al into 6 sorts as follows: 

  • Kind A: White house not up to 2 mm
  • Kind B: White house greater than 2 mm
  • Kind C: Brown house not up to 2 mm
  • Kind D: Brown house greater than 2 mm
  • Kind E: Horizontal white traces
  • Kind F: Horizontal brown traces

The tooth maximum regularly suffering from Fluorosis are Dog and Pre Molars/ in conjunction with 2d and third molars. The decrease incisors are those which might be hardly affected whilst the deciduous tooth are the very hardly affected teeth.
