28 NEWS Dental Tribune Middle East & Africa Edition | 4/2017 Indian walnut fruit beneficial in preventing periodontitis By DTI SEOUL, South Korea: Ethanol ex- tracts of the fruit of the Terminalia chebula tree, commonly known as Indian walnut, may be an effective means to prevent oral inflamma- tion and bone resorption, new findings of a South Korean study have suggested. is a plant T. chebula found throughout South East Asia. The properties of various extracts of its fruit have been widely studied and include antioxidant, antibacterial, anti-fungal and antiviral effects. Consequently, T. chebula is one of the most commonly used plants in traditional medicines on the In- dian subcontinent. In the study, the researchers inves- tigated the effect of an ethanol ex- tract of T. chebula in the treatment and prevention of periodontal dis- ease. The antibacterial effect was analysed using the disc diffusion method, and the anti-inflammato- ry effect was determined by molec- ular biological analysis of cultured cells mediated by bacteria associ- ated with dental plaque formation. In addition, the prevention of os- teoclastic bone resorption by the plant extract was explored using osteoclast formation and pit for- mation assays. The findings showed that the plant extract suppressed the growth of harmful oral bacteria and re- duced the induction of inflamma- tory cytokines and proteases while not showing cytotoxic effects. Moreover, it inhibited osteoclast formation in osteoclast precur- sors, thereby contributing to the prevention of bone resorption, the researchers found. In light of the findings, ethanol extracts of T. chebula may be an effective botanical chemopre- ventive agent that can modulate bacteria-induced inflammatory factors involved in gingivitis and periodontitis, the researchers con- cluded. However, further studies are needed to isolate and identify the beneficial chemical constitu- ents in the extract that could be exploited for pharmaceutical use, such as in mouthwash and other oral hygiene products. The study, titled “Use of ethanol extracts of Terminalia chebula to prevent periodontal disease in- duced by dental plaque bacteria”, was published on 16 February in the BMC Complementary and Al- ternative Medicine journal. Owing to its various health-promoting properties, Terminalia chebula is called the “King of Medicine” in Tibet. Researchers have now assessed the plant’s use in the prevention of periodontitis.

Each kit meets the specific needs of the different MAP System users (novice or accustomed general practitioner, endodontist and dental surgeon). The MAP Needles now come with colored plastic plungers according to their respective diameter, for easier use and size identification. The MAP System provides a unique and efficient method, enabling any dentist to place MTA or other endodontic repair materials with precision and no waste.
