Dental hygiene students from a local program visit a geriatric day care called Camp Sunshine to implement a service learning project. These older adults are functionally independent, although they are medically compromised. Under faculty supervision, the students screen the older adult clients to identify denture cleanliness and teach them how to clean their dentures daily. The goals are to improve their oral health by cleaning their dentures or partial dentures, increase their awareness of the need for daily oral care, and empower them to clean their dentures. The students compute the mean scores of the denture cleanliness measure for future evaluation of the program outcomes. The educational program consists of three weekly visits to teach and provide practice in various aspects of denture care. During the first weekly lesson, the students use motivational interviewing to identify the clients' current practices and intentions regarding daily denture cleaning. The students use this information to plan individualized instruction for each client. The students return in 6 months to measure denture cleanliness to evaluate the success of the program. Although the outcomes indicate improvement in cleanliness for the majority of the clients, the results are skewed as a result of a large number of them missing one of the weekly sessions because they came down with the flu that week. At the end of the program, the students prepare a final report in which they communicate the outcomes of the program to the facility director and propose funding of supplies by Camp Sunshine for future programs. 1.

Dental hygiene students conduct a study to compare the effectiveness of two non-alcohol mouthrinses, a 0.02% NaF rinse (Listerine Zero) and a 0.07% CPC rinse (Crest Pro Health), in controlling plaque biofilm and gingivitis. A sample of 136 healthy adult volunteers is taken from the university dental hygiene clinic. Only dentate adults with no to mild periodontitis are accepted to participate in the study. The study participants are qualified for inclusion in the study by their plaque biofilm forming potential and presence of mild gingivitis. Two groups are formed, and an unmarked bottle of mouthrinse is given to each participant. Study participants and examiners are unaware of the formula used by each participant. One group receives the 0.07% CPC mouthrinse, and the other group receives the 0.02% NaF mouthrinse. All other ingredients of both rinses are standardized. Two examiners are calibrated in the use of the PlI and GI to measure plaque biofilm at baseline, 2 months, and 4 months. The baseline PlI scores are used during group assignment to ensure that the two groups have equivalent oral hygiene. 1. What sampling technique is used for this study? A. Convenience sampling B.

The director of a local nursing home has contracted with a public health dental hygienist to design an oral health protocol for the 300 residents. Currently, a registered nurse performs the intake oral examination. The majority of the residents are partially edentulous, have partial removable dentures, and require assistance with daily hygiene practices. The caregivers state that the residents have severe halitosis, trouble eating, and frequently lose their removable partial dentures. The dental hygienist observes that the caregivers are neglecting daily oral hygiene care and are not conducting oral cancer screenings. On the basis of these observations, the dental hygienist determines to carry out oral hygiene and oral cancer screening of all residents and introduce an educational component for the facility's caregivers and interested family members. Students from the local dental hygiene educational program are recruited to assist with the educational program. The caregivers' knowledge is measured prior to and a week following the educational program; these measures are compared to evaluate changes in knowledge. The caregivers' ability to conduct oral cancer screening is evaluated weekly for several weeks after the educational program. The success of the program will be evaluated by screening the residents again 1 year later to identify any lesions that have not been found during the year. If the data reveal lesions that have not been identified, the dental hygienist plans to work with the director of nursing to establish a new protocol for routine oral cancer screening by the registered nurses on staff. The dental hygienist secures funding from a local foundation for the equipment needed to screen the residents. 1.

A dental hygiene U.S. Public Health Services (USPHS)- commissioned core officer is assigned to an Indian Health Service (IHS) clinic to improve the oral care of pregnant women in an American Indian rural community with a population of 26,000. Approximately 20% of the pregnant women in this population develop gestational diabetes. When a woman first sees the physician in the clinic for prenatal care, she is referred to the dental clinic for a dental examination. Only 25% of the patients referred over the previous 6 months complied with the dental referral, scheduled an appointment, and received treatment. The community is not classified a "dental manpower shortage area" because of the staffing of this clinic and the existence of this program. A survey of the pregnant women served by this clinic reveals that the women do not realize their risk for diabetes, are unaware of the relationship between oral health status and diabetes, and do not understand the benefits of an oral health assessment in relation to their overall health and the health of their babies. For the purpose of discussing the problem and possible solutions, the dental hygienist arranges a meeting of the medical clinic director, the dental clinic director, the medicine man of the Indian tribe, and a dental clinic staff member who is a member of the tribe. This team sets a goal of doubling the rate of compliance with the dental referral to 30% within 6 months. 1.
