I copy here the link to the news published to day in www.confectionerynews.com about the legal battle between Wrigley and Perfetti over the “WTF” trademark.
Wrigley considers that “WTF” can somehow overlap or coincide with their well-known brand “Winterfresh”. I have no other news about this issue other than the one appeared in this article, so I better just invite you to read it here
I would like to sure with you today this article published by Confectionerynews.com about the effect of sugar free gum on gingivitis. In particular the study mentions xylitol and maltitol gums, not gums with other bulk sweeteners.
This is the link to the article: Gingivitis and chewing gum
and this is the link to the clinical study itself: International Journal of Dental Hygiene
One more study to add in the list of oral care benefits of the chewing gum.
