New organic toothpaste may inhibit harmful bacteria ByDTI SEOUL, South Korea: A Seoul dentist has developed an all-natural tooth- paste that aims to reduce the health risks posed by Streptococcus gordo- nii, an oral bacterium that initiates dental plaque formation. Once in the bloodstream, which it may enter though bleeding gingivae, for exam- ple, the bacterium also causes blood clots, which can lead to life-threat- ening conditions such as infective endocarditis,heartattackorstroke. South Korean dentist Dr Hyung-Joo Moon, head of the Moon Dental Hospital in Seoul, recently obtained the patent for his bacteria-inhibiting organic formula from the Korean Intellectual Property Office. Conven- tional toothpastes mainly focus on combating two major oral bacteria, Streptococcus mutans and Porphy- romonas gingivalis, which are both associated with tooth decay and per- iodontal disease. However, inspired by a joint study by the Royal College of Surgeons in Ireland and the Uni- versity of Bristol, which found that S. gordonii can trigger an infection of the inner lining of the heart when entering the bloodstream, Moon started developing a toothpaste that especially inhibits the growth of thesebacteria. “Endocarditis is a serious disease treated only by surgery or strong antibiotics, which is becoming more difficultduetogrowingantibioticre- sistance. Considering this, using my toothpaste will reduce the risks po- tentially caused by the bacterium,” MoontoldtheKoreaTimes. The toothpaste’s anti-inflammatory ingredients include neem and cas- tor oil, herbal extracts made from psyllium seed, Japanese star anise, and Japanese cornelian cherry. “Un- like most other toothpastes that use artificial chemical preservatives, this toothpaste is only composed of natural, organic compounds, which greatly reduces the risk of side ef- fects,”Moonsaid. As the oral mucosa is very suscepti- ble to absorbing harmful substances into the body, it is especially impor- tant to use natural ingredients for oral care products, he emphasised. Tested among his patients, the toothpaste’s formula proved to help relieve inflammation, as well as sore gingivaeandtoothache. The toothpaste is not available for purchase yet, but Moon is working onreleasingittomarketsoon. implant tribune Dental Tribune Middle East & Africa Edition | 6/201617
