Researchers are collecting primary oral health data using the caries index DMFT. They collected data from a 9th grade classroom. There was a total of ten students who turned in their parental consent to participate in the study. The following DMFT scores were obtained: 1, 2, 5, 20, 5, 2, 6, 3, 4, 5 What is the grouped frequency, using intervals of 5 (1-5, 6-10, 11-15, and 16-20), for the second grouping?

A school district contracts with a local dental hygienist to begin a caries prevention program after a national report has indicated that the state had the highest tooth decay in the nation based upon DMFS indices. The dental hygienist is asked to develop a pit and fissure sealant and fluoride varnish program in all elementary schools in a rural district for children in grades K-5. This culturally diverse population consists primarily of children from lower socioeconomic status (SES) families. The only prior program in the schools was annual dental education conducted by the school nurses, based upon their assessment that the oral hygiene of the school children is poor. The concentration of fluoride in the water is 0.3 ppm and a previous fluoridation campaign was unsuccessful. The DMFT and dft will be measured at the baseline with plans to repeat the measures annually to monitor the effectiveness of the program. 3. All of the following are important risk factors for development of dental caries in this population EXCEPT one. Which one is the EXCEPTION?
