Kolkata: Scientists at a top-notch research institute in Durgapur have developed an easy-to-use, inexpensive kit to test the fluorosis level in the body so that one can take corrective measures before it causes teeth and bone deformity.
A team led by CSIR-CMERI scientist (surface engineering and tribology division) Dr Priyabrata Banerjee has developed the fluoride level detection kit that will soon be available in shampoo-like sachet. The sachets, to be priced around Rs 5 each, will contain two kits comprising two vials and a strip of colour-coded paper. While one vial will be empty, the other will contain a chemo-sensor liquid.
“All that a person has to do is spit into the empty vial, then pour the chemo sensor into it, close the vial and shake it vigorously. There will be an instant colour change, indicating the level of fluorosis in the body. If it is orange, it will indicate unsafe level of more than 1.5 ppm. Yellow indicates safe level of less than 1.5 ppm. The vial can be placed against the colour coded strip to match the colour and the fluorosis level it indicates,” Banerjee pointed out.
The Central Mechanical Engineering Research Institute (CMERI) is a leading mechanical engineering R&D institute under the aegis of Council of Scientific & Industrial Research (CSIR) that has developed technologies to provide societal solutions. The folurosis level detection kit is one such that has already been provisionally patented and technology tranferred to small scale industry for commercial production. The institute showcased this and other technologies at the 31st Indian Engineering Congress organised by the Institute of Engineers (India) in Kolkata recently.
“We expect the kits to be available in health stores in rural Bengal, particularly villages in Purulia, Bankura and Birbhum where fluorosis is a problem,” said Banerjee, who is the key inventor. Fluorosis can be dental, skeletal or non-skeletal and cause motteled teeth or deformity of limbs.
Banerjee’s team has also developed a chemo sensor station costing around Rs 2,000 each that will be placed at the primary health centres in fluorosis-affected districts where people can get the samples electronically verified.
“The salivary fluoride level detection kit is the latest technology that our scientists have come up with. The patent for this product was filed on November 18,” said CSIR-CMERI director Harish Hirani.
Another technology that the R&D institute demonstrated was a smart card operated and pluggable energy meter through which one can instantly measure the energy level of an electrical installation using a smart phone. “One only needs to have internet connectivity or bluetooth to link a smart energy meter with a smartphone,” said a scientist.
