Epi Dental Fluorosis

hypoplasia and hypomineralization: which is qualitative and which is quantitative

hypoplasia: quantitative

mineralization: qualitative

Dental fluorosis is alteration in tooth caused by excessive fluorosis during?

appears as diffuse __ white opacity

tooth development, bilateral

most important determinates of fluorosis

Fluorosis is a __ condition

Quantity and timing

dose response

More important etiologic factor: spikes or exposure?

Constant exposure

What is the most sensitive stage for development?

early maturation stage of enamel

Where is fluorosis most common?

2nd molars in primary dentition

Dean’s fluorosis index

Score corresponding to clinical apperance of second most severly affected tooth in mouth

Geographic location based on mean of all scores

Fluorosis confied to only incisal edges of anterior reeth and cusp tips of posterior

snow capping

Fluorosis risk index

Age specific exposures to fluoride sources and development of fluorosis

Two classifications

• Formation during first year of life

• Third thru sixth years

In general, Primary tooth fluorosis is __ and _ than fluorosis in permanent dentition

less prevalent and less severe

Prevalence of fluorosis __ from 30’s to 2020, with the largest ?

increased, largest increased in suboptimal fluoride group

most dental fluorosis in US is

mild

Excess fluoride during enamel maturaiton leads to ?

excess retention of protein

Tooth wear is

non-carious, pathological loss of tooth tissue (physical injury like AAA, or erosion)

Tooth erosion

Etched away from tooth surface by acid or cehlation WITHOUT bacterial involvement

Erosion: lesion is usually?

what surfaces usually for vomiting vs carbonated bev

shallow, broad smooth, polished, scooped out depression on enamel surface (usually adjacent to DEJ)

Vomit: lingual

Carbonated; labial

Prevalence of dental erosion increases with?

Age

__% of american children age 13-19 had dental erosion in at least one tooth and up to 80% of adult

46%

Besides age, what else increases erosion risk?

males, higher weight

Dental fluorosis prevalence has increased in both __ and _ areas

fluoridated and non fluoridated

Non fluoridated community rates of fluorosis

Fluoridtated community rates

10-40%
