In this data set, the numbers represent the number of children who have visited the dentist through the years 1997 to 2014. For my project, I plan to use the total number row for the ages 2 and over and 2 to 17 years of age since my research focuses on children. Over the years, it is significant that the number of visits have increased because children are clearly getting treated for their dental caries. This shows that children need to make a change in their diet and nutritional status to prevent paying high costs of dental care. The data set is approximately current even though it was conducted two years ago. The trustworthiness comes from the the website itself, cdc.gov. This website is known for providing credible and reliable information on the topic of health.

The data set presented in this journal shows the percent of dental caries present and the percent that are untreated from ages 4-5 and 6 years old. In addition, it focuses primarily on the provinces in South Africa. This data set could be useful for my project because it adds some variety by not just focusing on dental decay in America but rather somewhere else in the world. The data set was completed in 2007 which is not that recent and could interfere with the recency and usefulness of the data. As for trustworthiness, the data was published in an academic journal and this shows that the data was accurate enough to show how the number of untreated caries have decreased compared to the percent of caries there were in each province.
This table shows the different companies of fruit juices that children consume the most. The data focuses on fruit juices because it’s one of the drinks that is found to be the most cariogenic, or tooth decay causing. The usefulness of this data set comes from the percent of sugar added to the drink. Furthermore, sugar is known to cause dental decay and this data will be useful to the reader to see and compare the different types of fruit juices and how they are linked to dental health problems. This data set is trustworthy because it comes from an academic journal which shows that the information is reliable enough to utilize for my project. The numbers in the set are current since the study in the journal was published in 2016 and this shows that the information is recent enough to use as it will help the reader trust the information on a better level.
