The Revelations of Volcanic Soil On Teeth.


The soil that is formed after the eruption of a volcano is called volcanic soil. Such soils are very fertile and good for agriculture purpose. However, there always exists a danger of future volcanic eruptions which can cost many lives. this type of soil constitutes 1% of the earth soils and nearly 10% of the human population reside in such soil. This shows that good amount of the worlds population has established their lives on volcanic soil.

Popular thinking is that fresh volcanic soils contain more of silica, potassium and fluorides. However, this soil gains more of organic content as it becomes older and dormant. There always exists a differing amount of soil mineral content in dormant and active volcanic soils.

The crops which are grown in volcanic soil possess the minerals and other elements which are native volcanic soil. These agents enter the human physiologic system which in turn may promote the health or cause deleterious health effects. This means that residing in the volcanic soils is always like encountering the double-edged sword.

In regard to dental health, popular thinking is that volcanic soils are rich in fluorides and the levels of this fluoride is high in fresh eruptions. People living in such areas may have the benefit of fluorides on their teeth in the form of caries prevention. But, there is possibility of occurrence of dental  and skeletal fluorosis. Fluorosis  happens when the levels of fluoride are beyond the optimum.  but, this may not be always true because as time passes after volcanic eruptions upper layer of soil florid levels may get reduced, thus we need have an individual soil study correlating with human and dental health

On the other hand, some literature shows that volcanic soils are deficient in selenium. This may contribute for the porosity of bones including jaw bones (Osteoporosis).

Chances of dental caries decrease with decreasing level of selenium in the body.  Since volcanic soils are relatively deficient in selenium there are lesser chances of selenium promoted dental caries. These discussions suggest that the opinion of volcanic soil on teeth are still unclear and cloudy.

Hence it is recommended to create awareness among the residents of volcanic areas and also the health officials, so that, soil,organic and inorganic content estimations are to be done. These estimations help to take necessary actions to combat the relevant heath effects.
