A group of students was interested in conducting an outreach program at their nearest long term facility with elderly patients. They were interested in caries risk, so they asked for 25 volunteers one evening during a health fair event and conducted open mouth exams using explorers, mirrors, and the lights from their loupes. They used a caries index and a dry mouth index to assess caries experience and xerostomia then conducted a 6-month program and a study. They had one half of the group using Biotene and Xylitol products daily and gave the other half of the group fluoride varnish applications every 3 months. At the midpoint and at the end they evaluated their patients in the program. Use this information to answers questions #1-5.    What caries index would be appropriate for this population group?

A high school class of ten physically challenged students, 14-19 years of age, shows a need for improved oral hygiene. The high school nurse has asked the districts dental hygienist to assess their needs and to work with the nurse to implement a dental public health program for these students. The dental hygienist plans to set up a portable dental unit to orally screen the students and to implement an evaluative tool to understand the dental health knowledge of the group. Additionally, the hygienist plans to provide oral hygiene instruction each month during the remainder of the school year and the nurse will follow up with the instructions once a week.  The O’Learys plaque score at the initial assessment of the class was:  25%, 25%, 50%, 50%, 60%, 60%, 60%, 75%, 75%, and 100% The mean score for OHI-S score of the ten students was 4.8 Use this information to answer questions 22 – 27. Based on the severity of the physical disabilities, the dental hygienist may need to make accommodations for all of the following EXCEPT one. Which one is the EXCEPTION?

A dental hygienist employed by a children’s hospital dental clinic is responsible for coordinating programs to serve medically compromised children in the service area.  The population consists of a mix of diverse SES and ethnic groups.  The dental hygienist’s responsibilities include managing the clinic that provides dental and dental hygiene treatment for the children, training hospital staff in the daily oral care of hospitalized children,  serving as a resource to the hospital staff, conducting oral hygiene educational programs for clinic patients and their parents, and supervising the distribution of self-care fluoride products.  The effectiveness of the educational programs is evaluated by comparing pre-test and post-test scores of knowledge and oral health behavior of the clinic patients.   Answer questions #28-31 The primary role of the public health dental hygienist in this scenario is to provide direct patient treatment.  The dental hygienist’s role in this program is primarily coordination, training, and serving as a resource that fulfills the role of the public health hygienist.
