Iranian Researcher MHN Device to Find Calcified Root Canals in Tooth
“When the space inside the root canal is completely blocked by calcium tissue due to age or a disease, finding the canal becomes a serious problem for the dentist,” Mohammad Hossein Nekoufar, a specialist in root canal therapy, told ANA.
“To settle this problem, I designed a device that can find the microscopic holes carved in the bottom of the cavity by sending different types of alternating currents into the root,” he added, noting that the holes can be seen with neither a naked eye nor a microscope, and this electronic tool can find them for the dentist.
Nekoufar said that an agreement with a Chinese company has been made to commercialize the MHN device, adding that the company provided 10 dentists across the world with the device and they confirmed its good quality.
Earlier, in January, a knowledge-based company in Iran had also succeeded in manufacturing nanocomposite dental cement based on zinc phosphate with high anti-corrosion and antibacterial properties for tooth restoration.
“Nanocomposites are the latest generation of dental composites that enjoy higher strength and resistance than other composites,” Nazanin Farhadyar, the managing-director of the knowledge-based ‘Nano Pouyesh Yekta Nano’ company, told ANA.
“Conventional non-nano zinc phosphate cements are not antibacterial and are less hard than other cements due to their low thickness, but the nano zinc phosphate composite made in our company has high anti-bacterial and anti-corrosion properties and is used as a dental cement for orthodontics, bridges and restoration,” she added.
Development and production of nano materials, different types of special and custom nano catalysts, nano absorbents, nano fibers, natural polymer nano capsules, and metal nano oxides, and holding specialized courses in the field of commercialization of nano products, start-up of new nano technologies and safety of nano materials are other activities of the knowledge-based company.
