Damascus-SANA
With efforts and perseverance, and based on the saying “An ounce of prevention is better than a pound of cure,” an integrated work of a dentist and engineer succeeded in creating a smart electric toothbrush capable of self-detecting cavities.
Dr. Lina Al-Refai explained in a statement to SANA reporter that this brush serves as a home warning of the necessity of visiting the dentist before any feeling of pain, which saves the patient severe pain in addition to saving large financial costs such as the price of nerve fillings and dental implants.
For her part, the engineer, Duha Zara, indicated that inside the brush there is a device consisting of an electrical circuit that depends on the difference in electrical resistance between the enamel of the healthy tooth and the injured one, as it applies an electric voltage of 5 volts to the surface of the enamel, and it issues orders stating the presence or absence of caries, pointing out that the teeth consist of a structure A monolith of hydroxyapatite crystals which serves as an insulator or semi-electrical insulator.
Regarding the mechanism of action of the brush, the team said that as soon as it touches the healthy tooth, a green light appears. But if the tooth is infected, the device gives an audible alert, in addition to changing the color of the light to red, which helps the patient to know that he has a dental problem that requires an early visit to the doctor.
At the end of last year, the Ministry of Internal Trade and Consumer Protection granted the project a patent after it was evaluated by the Faculties of Dentistry and Mechanical Engineering at Damascus University as the first in the world. It also won the second prize in both the Excellence Competition and the Bright Inventor Competition.
It is noteworthy that the smart electric toothbrush project was among the pioneering youth projects hosted by the first pioneering investment forum “Opportunity 2022” organized by the National Union of Syrian Students and the Young Entrepreneurs Association “SIA”.
For his part, the Chairman of the Board of Directors of the Young Entrepreneurs Association, Louay Al-Munajjid, indicated that the association’s goal is to stimulate the pioneering energies of Syrian youth by unleashing their latent creative forces and providing them with knowledge and skills to enter the labor market and linking them with financing institutions to complete their projects easily and easily.
