Dental hygienists work under the supervision of licensed dentists. Idaho State University's four year dental hygienist degree instructs students on basic and complex skills and knowledge needed in the healthcare field. Freshman and transfer students are accepted. The Bachelor of Science in Dental Hygiene degree provides adults with soft and technical skills. Among these skills are community disease prevention, tooth morphology, dental materials, leadership and health policy and oral pathology. During clinical sessions, students learn how to perform root planting, apply fluoride therapy and develop x-rays. Opportunity to get advanced training is offered through the school's Master of Science in Dental Hygiene program.
