AI synopsis

What people are saying

Discussions reflect a nuanced view, with some posts noting the study's findings on increased tooth decay and methodological limitations, while others question the interpretation or relevance of the data. The tone varies from cautious acknowledgment to skepticism, with references to specific data such as the comparison between Calgary and Edmonton and mentions of the importance of ongoing research.

AgreementModerate agreement

Most discussions express slight agreement or acknowledgment of the study’s findings, particularly around the increase in dental caries after fluoridation cessation.

InterestModerate interest

The discourse shows moderate interest, with participants referencing specific data points and study limitations, indicating engagement with the scientific content.

EngagementModerate engagement

Posts demonstrate active engagement by referencing studies, sharing sources, and discussing implications, showing a desire to understand the topic deeply.

ImpactModerate impact

The group collectively recognizes the potential implications of the study, especially related to public health policies on fluoridation, suggesting perceived significance.

Abstract in brief

  • This study compares the impact of stopping water fluoridation on dental caries in Grade 2 children from Calgary (where fluoridation stopped in 2011) and Edmonton (where it continued), analyzing changes in tooth decay over time, especially on smooth surfaces where fluoride's effect is most significant.
  • The researchers found that overall primary tooth decay increased more in Calgary after fluoridation stopped, suggesting an adverse short-term effect, while trends for permanent teeth showed a possible early negative impact that needs further monitoring.
  • The study emphasizes the importance of ongoing data collection to better understand the long-term effects of fluoridation cessation on children's dental health.]

@nyscof @jwilcox79 @sjohn2000 A 2016 study that compared tooth decay in children in Calgary and Edmonton (which maintained fluoridation) from 2004-2014.

@dr_coffman @AlpacaAurelius They should focus on how tooth decay rates went down in the permanent teeth in Calagary in that study. "For all tooth surfaces among permanent teeth (Table 1a), there was a statistically significant decrease in Calgary, for the overall mean DMFS" https://t.co/OuOxoZVbfp

Measuring an increase in treatment for caries is not a good measure of a populations tooth decay. This is a variable that is modifiable. https://t.co/kwMbVCqBMe

In summary a lot of data clearly shows there is little to minimum advantages by adding chemicals to #YEG water to treat tooth decay... What we can educate on diet change, less soda drinks & cotton candy. We are exposed to Fluoride enough. Leave it out.✍️
