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, taken the summer before commencing the on-site DHYG courses.

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. This program has limited enrollment.

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

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

Support the Patient Care Fund

Your support enables CBC Dental Hygiene students to provide non-surgical periodontal therapy (NSPT) to those in need in our community. In order for the students to provide comprehensive inital periodontal therapy for one patient, it costs our clinic $312. The Patient Care Fund provides funds to cover the cost of four quadrants (full mouth) of NSPT, re-evaluation, and one periodontal maintenance cleaning.  This service provides vital training to our students while making a real and tangible difference in the lives of our patients.

Individuals engaged in the provision of dental hygiene services may encounter exposure to blood borne pathogens (BBP) and airborne viruses, potentially resulting in human disease.  The Dental Hygiene program adheres to the practice of Standard Precautions as defined by OSHA (Occupational Safety and Health Administration). This adherence ensures the implementation of measures to minimize health risks to students, patients, staff, and visitors. Standard Precautions are essential for all facility personnel, faculty, and students who, in their regular duties, might expect contact with blood and other potentially infectious materials containing organisms such as HIV, HBV and HBC.

The program uses guidelines set by the CDC (Center for Disease Control) to determine the appropriate PPE (Personal Protective Equipment) for faculty and students in the clinical setting. Strict adherence to these guidelines aims to reduce the risk of exposure to BBP and airborne viruses.

Accepted students will act as mock patients alongside student partners during their two-year tenure in the Dental Hygiene program.

Each state, the District of Columbia and the U.S. protectorates vary in what professions they require to be licensed and the educational requirements for those licenses. It’s important to understand whether the degree or certificate you obtain from CBC will meet the educational eligibility requirements for a license in the state in which you plan to practice.

View educational licensure requirements by state.

National Background Search & Drug Screen Requirement

As part of the admission requirements for Health Science programs, accepted applicants must successfully pass a criminal background check and drug screen prior to working with patients in clinical areas. The background check and drug screen are paid by the student and administered through a third party company, CastleBranch. In addition to the background check required by CBC, each clinical facility reserves the right to conduct its own criminal background check prior to allowing a student to enter its health care facilities for clinical participation.

Certain criminal convictions, pending charges or negative actions may automatically disqualify a person from having unsupervised access to vulnerable adults, juveniles and children. Clinical facilities reserve the right to accept or decline a student’s placement in its facility.
