Week in Review: New perio system | Is water fluoridation effective? | Kids' dental fear

Dear DrBicuspid Member,

Periodontitis classification has gotten its first update in 20 years. A new staging and grading system for periodontitis is one of the highlights of a June 21 publication by the American Academy of Periodontology. The publication also features the first classification for peri-implant diseases. Learn more here.

The dental community generally praises the merits of fluoride, but how effective is water fluoridation at preventing caries? Pretty effective, according to the results of a new study that investigated the association between community water fluoridation and dental caries occurrence. Read more here.

Not all endodontic files are equal when it comes to reducing pain after root canal treatment. A new study found that patients reported less pain after being treated by one type of nickel-titanium file. See which endodontic system came out on top here.

Finally, family structure may partly influence whether children experience dental fear and anxiety, according to the results of a new study. Researchers found that children with siblings feared the dentist more than only children. Read why they think this is the case here.
