A researcher conducts a study in which 200 persons with oral cancer and 200 without oral cancer are identified. Following getting their informed consent, information is collected about past exposure to a group of variables (such as alcohol and tobacco usage, amount of pizza eaten and the oral burns sustained from eating hot pizza) suspected of being responsible for the oral cancer. What type of study is this?

As part of a research methods course, a DH student decides to monitor all allied health science students (nursing, public health and hygiene) on campus to determine how many students have obtained their Hepatitis B vaccine series. The DH student looks that the allied health students medical records submitted at the beginning of the semester This BEST describes which of the following principles of research?

As part of an alternative spring break project, 5 DH students were funded by the IHS to participate in a dental screening project on a Native American reservation. The students join a staff of 3 RDHs and 2 DMDs. The students are expected to conduct smoking cessation education for adult members of the reservation for 2 days and conduct oral health screenings for the remaining 3 days.

On the student's 1st day, the entire group spends 8 hours in a calibration session so that they would consistently score equivalently when conducting the screenings. The calibration training ensures what?

The students are expected to conduct smoking cessation education for adult members of the reservation for 2 days and conduct oral health screenings for the remaining 3 days.

One of the goals of the screening is to determine the periodontal health of the adult members of the reservation. What is the BEST index for assessing periodontal status in this situation?

A director of a community based center needs documentation on the oral hygiene status of the adult population receiving care at the clinic. The director seeks to collect data that can be understood by both dental and non-dental professionals. What is the BEST way to evaluate overall oral hygiene status in this population?

Today, caries are mostly evident where in the permanent teeth for children?

There is higher prevalence of root caries in males and African Americans. The prevalence of root caries tends to decrease with age.

Which of the following statements about utilization of dental services is incorrect?

A new patient comes into your office and you do a comprehensive exam. The patient came to your office because you offer free x-rays and whitening with new patients. The chief complaint is the yellow-ness of her teeth and does not have any health or other oral health concerns. Upon your assessments, you find multiple sites of BOP on the Maxillary Right along with deeper probing depths. You also find a round, red lesion with a white halo on the buccal mucosa adjacent to #20. You take an FMX and impression for the whitening trays as well as treatment plan SRPs on the UR quad. You plan a re-eval 4 weeks after the SRP.

Your treatment plan of SRPs is an example of what?

You are employed as a public health RDH in a local health department and are about to develop the first oral health unit in the department. You are asked to plan, implement, and evaluate a school-based educational and preventive program for selected high schools in the school district. Your plan includes classroom education and the use of a mobile dental van to provide screenings, cleanings, sealants, fluorides, and referrals to dental homes. Data will be collected using the DMFT index.

The index used to collect data will be helpful in assessing which of the following?

You are employed as a public health RDH in a local health department and are about to develop the first oral health unit in the department. You are asked to plan, implement, and evaluate a school-based educational and preventive program for selected high schools in the school district. Your plan includes classroom education and the use of a mobile dental van to provide screenings, cleanings, sealants, fluorides, and referrals to dental homes. Data will be collected using the DMFT index.

Five years after starting this program, you contact the students that initially participated in this program and conduct a DMFT. You compare the DMFT results to the DMFT results you gathered when you first began your program. You do this research in order to see if your services were beneficial to this population. What type of epidemiological research are you conducting?

You screened 500 students in the school district. The data includes:

• 55 decayed permanent teeth requiring fillings

• 20 deciduous teeth requiring fillings

• 19 decayed permanent teeth that needs to be extracted

• 49 filled permanent teeth

· 14 permanent teeth have been extracted due to caries.

What is the count of decay in the DMFT for this population?

You have the following information from the DMFT from the high school students you screened and data that your colleague collected from the high school students from a neighboring county that has a higher SES.

Data from the High School Students

D = 109

M = 12

F = 49

Total = 170

Data from the neighboring county

D = 63

M = 20

F = 87

Total = 170

What can you conclude from this?

You decide to collect baseline data on the older adults who visit your public health clinic in order to document their needs and possibly to use the data in securing funds for program development geared towards this population. You want to measure the health of gingiva, presences or absence of bleeding, calculus, periodontal pockets, and loss of attachment. The index of choice for this purpose is which of the following?
