Education and training. A high school diploma and college entrance test scores are usually required for admission to a dental hygiene program. High school students interested in becoming a dental hygienist should take courses in biology, chemistry, and mathematics. Also, some dental hygiene programs require applicants to have completed at least 1 year of college. Specific entrance requirements vary from one school to another.
In 2006, there were 286 dental hygiene programs accredited by the Commission on Dental Accreditation. Most dental hygiene programs grant an associate degree, although some also offer a certificate, a bachelorís degree, or a masterís degree. A minimum of an associate degree or certificate in dental hygiene is generally required for practice in a private dental office. A bachelorís or masterís degree usually is required for research, teaching, or clinical practice in public or school health programs.
Schools offer laboratory, clinical, and classroom instruction in subjects such as anatomy, physiology, chemistry, microbiology, pharmacology, nutrition, radiography, histology (the study of tissue structure), periodontology (the study of gum diseases), pathology, dental materials, clinical dental hygiene, and social and behavioral sciences.
Licensure. Dental hygienists must be licensed by the State in which they practice. Nearly all States require candidates to graduate from an accredited dental hygiene school and pass both a written and clinical examination. The American Dental Associationís Joint Commission on National Dental Examinations administers the written examination, which is accepted by all States and the District of Columbia. State or regional testing agencies administer the clinical examination. In addition, most States require an examination on the legal aspects of dental hygiene practice. Alabama is the only State that allows candidates to take its examinations if they have been trained through a State-regulated on-the-job program in a dentistís office.
Other qualifications. Dental hygienists should work well
with others because they work closely with dentists and dental assistants as
well as dealing directly with patients. Hygienists also need good manual
dexterity, because they use dental instruments within a patientís mouth,
with little room for error.
