The Dental Hygiene program provides knowledge and skills necessary for the dental hygienist to work with a dentist and to provide direct patient care to patients. The services dental hygienists provide vary somewhat from state to state. Routine functions include: scaling, peridontal therapy, and polishing teeth; applying preventive and other topical agents to the teeth; taking and processing x-rays; assessing the patient's health and the health of the supporting structures of the teeth; providing patient education, providing pain control measures such as local anesthetic and conscious nitrous oxide sedation, and providing dental health education in the community. The curriculum includes content in general education; bio-medical, dental, dental hygiene, and clinical sciences; and clinical practice. Graduates are eligible to write the National Board and take the Central Regional Dental Testing Service, Inc. exam. Application to the Dental Hygiene Program must be completed before March 1 of the year in which a student wishes to attend the Dental Hygiene program. The selection of students is done on a point system using the Dental Hygiene Application Assessment Sheet to rank applicants. If accepted into the program, the student must complete and pass an annual background check required by the Minnesota Human Services licensing division, complete the Hepatitis B series, be certified in First Aid and CPR, and current in immunizations.
