Dental assistants help dentists with many aspects of thier practice, from record keeping to patient care. According to the Bureau of Labor Statistics, dental assistant duties vary by state and may vary by individual dental practice as well. Requirements to become a dental assistant also vary by state. Some states require assistants to graduate from an accredited program and pass a state exam, while other states do not require any formal educational training. Most community colleges, trade schools, and adult education centers across the U.S. offer dental assistant training programs.

Butte County Regional Occupational Program

Many counties have regional occupational programs that offer courses for both high school students and adults. Often, these programs are offered at little to no cost for high school students, but charge adults tuition. The Butte County ROP in California offers a nine-month dental assisting program. This program requires students to be at least 18 years of age, possess a tuberculosis clearance, have received hepatitis B immunization and general computer skills. Internships are available, and upon completion students are eligible to take the Dental Board examination that provides state certification as a Registered Dental Assistant.
