Caries, better known as cavities, is one of the most common diseases of the teeth. The calcified tissue becomes demineralized, resulting in a cavity. In severe cases the tooth’s pulp is exposed and sometimes it becomes infected or abscessed. For a review of teeth, see our Lab Manual.
The factors responsible for caries are not well understood but soft foods and carbohydrate-rich diets have been implicated. Apparently foods that stick to the teeth, particularly processed carbohydrates (like corn that has been ground and cooked), encourage certain bacteria to flourish and produce acids that break down the tooth. Tables 1a and 1b shows the number and percentages of children, adolescents, and adults by the type of cavities they had.
Procedure
Review and graph the data.
Analyze the data for what it reveals about the health of each community.
Use the information on this page and what you have learned from the data to answer the questions listed below.
*ALL DATA IS ADDED AS FILES, PLEASE CHECK.*
Key
#C represents the occurrence of each type of cavity out of the total number of cavities for each group. For example, of all the cavities that occurred in Hardin Village adult males (371), 92 of those cavities were occlusal.
%C represents the percentage of each type of cavity in relation to the total number of cavities for each group. For example, of all the cavities that occurred in Hardin Village adult males (371), 24.8 percent of them (92) were occlusal.
#N1 represents the number of individuals with each type of cavity. For example, of all the Hardin Village adult males who had cavities (55), 36 individuals had occlusal cavities.
%N1 represents the percentage of individuals who had each type of cavity in relation to all individuals in that group. For example, of all the Hardin Village adult males who had cavities (55), 65.5 percent of them (36 individuals) had occlusal cavities.
*BELOW ARE THE QUESTIONS YOU ARE RESPONDING TO, PLEASE MARK WITH NUMBERS WHEN RESPONDING(1. 2. 3. 4.)*
Questions
Answer the following questions (answers must be in complete sentences and I expect at least 2-3 sentences for question 4):
What do you notice about the distribution of cavities in children?
What do you notice about the frequency of total cavities between the two groups?
What conclusions could you draw from this data and the information you have been given?
Write down any other observations you have about this data set.
Below is an example of what my classmate responded DO NOT COPY ANY OF IT. This is just for reference.
What do you notice about the distribution of cavities in children?Children aged 5 to 19 years old from low income families are twice likely to have cavities compared with children from higher income.
What do you notice about the frequency of total cavities between the two groups?Although dental cares are preventable, they remain the most common disease of children aged 6 to 11 years.
What conclusions could you draw from this data and the information you have been given?The sooner children get dental checkups, the healthier their mouths will be. Early checkups prevent cavities and tooth decay. Having this disease can be really painful, trouble concentrating among others.
Write down any other observations you have about this data set.Tooth decay in children is caused by bacteria in the mouth this bacteria make a sticky substance called plaque that can eat away a tooth enamel.
