If a child with scabies attends day care or the affected person is institutionalized (such as in a nursing home or prison), then staff and others in close contact with the person should be treated. It is best to treat everyone simultaneously to minimize the risk that untreated people will reinfest treated people.
Education and Qualifications. To become a dental hygienist, you'll need either a 2- or 4-year degree in dental hygiene. Most programs are two years long and lead to an associate's degree. They are offered through community colleges and technical colleges.
According to the U.S. Bureau of Labor Statistics (www.bls.gov), the minimum educational requirement for work as a dental hygienist typically consists of a 2-year certificate program or associate's degree program in dental hygiene from an institution accredited by the Commission on Dental Accreditation.hile an undergraduate degree is all that's necessary for a clinical career in dental hygiene, some dental hygienists pursue advanced education in the field. Advanced degree programs are generally reserved for students who plan to pursue academic and research careers or practice in school or public health programs.
