Prevalence of dental fluorosis and associated risk factors in school children from Kanyakumari district, Tamil Nadu - Paper published in the Indian Journal of Dental Research
This paper published in the Indian Journal of Dental Research describes the findings of a study that aimed at assessing the oral health status of 11-15 year old school children from Kanyakumari district. The survey focused on determining the prevalence and severity of dental fluorosis along with assessing the various risk factors involved. Nearly 12 million of the 85 million tons of fluoride deposits are found in India. It is therefore not surprising that dental fluorosis is endemic in 15 states of India. The highest rates of endemicity have been reported from Andhra Pradesh, Haryana, Karnataka, Punjab and Tamil Nadu.

A total of 1800 children  from all the nine blocks of Kanyakumari district from 6th to 10th standard were examined using type III examination. Dental fluorosis was present 15.8% of the study population and varied from as low as 1.4% to as high as 29.4% in different areas. There was a significant difference in dental fluorosis levels between rural and urban residents.

The report recognises that most groundwater quality problems are anthropogenic in origin, caused by a combination of over-exploitation and infiltration of wastes. Inadequate infrastructure and resources mean that waste generated by cities and industrial areas is not properly collected, treated and disposed, thus leading to grondwater contamination.
