Dental Hygiene Program

Earn your Bachelor of Applied Science in Dental Hygiene at CBC!

The Dental Hygiene program demands full-time classroom and clinical commitment and spans eight quarters total:

• Seven quarters dedicated to dental hygiene (DHYG) instruction
One additional quarter for online 300-level bachelor courses, recommended to be taken the summer before commencing the on-site DHYG courses.

• This program has limited enrollment of up to 24 students each year.

At the CBC Dental Hygiene Program, our clinic serves both new and longstanding patients, offering a dynamic environment for hands-on experience. However, it's essential to understand that graduating requires fulfilling specific patient requirements and clinical assessments. Consequently, students are in charge of their schedules, including booking appointments and communicating with patients. While the program provides a foundational patient pool, students must be proactive in managing their patient interactions; the dental hygiene program does not solely oversee student scheduling.


The educational objective of the program is to prepare students who, upon graduation and successful completion of the National Board Dental Hygiene Examination (NBDHE) and Regional Board exams in Local Anesthesia, Restorative and Clinical Dental Hygiene, will be able to apply for licensure and practice Dental Hygiene. 

Commitment to a Humanistic Culture and Learning Environment

Columbia Basin College’s Dental Hygiene Program is committed to fostering a humanistic culture and learning environment that is grounded in compassion, integrity, diversity, and professionalism. This commitment directly aligns with Columbia Basin College’s (CBC) strategic priorities, which emphasize student success, inclusive and equitable teaching practices, and creating a welcoming community for all. By integrating CBC’s goals into our curriculum and clinical practices, the Dental Hygiene Program ensures that students receive high-quality, culturally responsive education, preparing them to serve diverse patient populations effectively and ethically.

Infection Control Policy

In accordance with CODA (Commission on Dental Accreditation) standards, CBC maintains a comprehensive Infection Control Policy. This policy ensures compliance with Centers for Disease Control (CDC) guidelines and Organization for Safety, Asepsis, and Prevention (OSAP) best practices to protect students, patients, and faculty. All students receive thorough infection control training and are expected to adhere strictly to safety protocols throughout the program.

The CBC Dental Hygiene program is accredited by the Commission on Dental Accreditation (CODA).

Dental Hygiene Program Accreditation and Licensure

The Columbia Basin College Dental Hygiene program is fully accredited by the Commission on Dental Accreditation (CODA), the nationally recognized accrediting agency for dental and dental-related education programs. The next CODA site visit is scheduled for October 2025. This accreditation assures that the curriculum meets rigorous national standards, preparing students for professional licensure and successful careers in dental hygiene. For more information about CODA, visit the Commission on Dental Accreditation website above.

In Washington State, licensure as a dental hygienist requires graduation from a CODA-accredited program, successful completion of national and regional board examinations, and compliance with the Washington State Department of Health’s regulations. CODA accreditation is a vital step toward meeting licensure requirements and practicing safely and effectively within the state’s scope of practice.

For more details on Washington’s dental hygiene licensure requirements, visit the Washington State Department of Health Dental Hygiene Licensing page.

Scope of Practice

The scope of practice for licensed dental hygienists in Washington State is defined under RCW 18.29.050. This statute outlines the functions a dental hygienist is legally permitted to perform, including preventive and therapeutic dental procedures, under varying levels of supervision. Dental hygienists may be employed in dental offices, public health settings, schools, and other healthcare environments. The level of required supervision, general or direct, depends on the specific procedures being performed and the setting. For detailed information, please refer to the full statute: RCW 18.29 – Dental Hygienists 

Information Sessions are offered regularly throughout the year to give you an opportunity to meet the Director of Dental Hygiene, Counseling and Financial Aid. Information is provided regarding required prerequisites, the application process, and progression through the curriculum. Attendees will have the opportunity to ask specific questions about the program.

Information sessions are scheduled for one hour and are free and open to anyone interested in a CBC Health Sciences program.

The Dental Hygiene program at CBC requires an expenditure of approximately $37,000 for tuition, books, uniforms, supplies and equipment during the two-year program. These figures are estimates and subject to change. Approximately $7,000 will be needed prior to the beginning of the first quarter. Upon graduation, students must take the NBDHE (National Board Dental Hygiene Exam) and a Regional board exam that includes Clinical boards on Local Anesthesia, Restorative (placing fillings on a typodont) and a Clinical board on a patient. These costs are in addition to the quoted cost of the program and are the responsibility of the student. Successful completion of these exams are required for licensure.

The Dental Hygiene program offers low cost dental care to adults, teens and children in our community. Procedures are performed by students in the program and are supervised by local dentists and also registered dental hygienists who are faculty members in the program.

Dental Hygiene Clinic
