Dental Hygiene - AAS Degree

Overview

Limited Entry Program

See Department website and program contacts here

The Dental Hygiene (AAS) degree is designed for students seeking careers as licensed dental hygienists. The curriculum combines classroom instruction, laboratory learning, and extensive clinical experience to prepare students for professional practice in dental and healthcare settings.

Coursework includes topics such as dental hygiene therapy, oral anatomy, pathology, expanded functions, local anesthesia, restorative procedures, and preventive oral healthcare. Students develop practical clinical skills through supervised patient care experiences and hands-on training in clinical environments.

The Dental Hygiene program is completed over seven terms and is workforce-focused, emphasizing practical, applied learning that prepares students for licensure and employment in the dental hygiene field. During the program, students prepare for and complete National and Regional Board examinations required for professional licensure.

Graduates who complete program and licensure requirements may pursue employment in dental offices, community health settings, public health programs, and related healthcare environments. Students interested in additional educational opportunities may also pursue transfer pathways toward bachelor’s degree completion.

Because this is a limited entry program, students should review application requirements carefully and work with program advisors regarding eligibility, prerequisite completion, and program planning.

Statement to Applicants Regarding Exposure to Bloodborne and other Infectious Diseases

Dental hygienists are professionals who practice direct patient care and are therefore potentially exposed to a number of serious infections and bloodborne disease pathogens. Among these are hepatitis viruses, influenza, and HIV infection. The program curriculum includes in-depth study of disease transmission and comprehensive preventive practices in order to ensure students, patients, faculty and supervising dentists are as safe from exposure as possible.

The program follows up-to-date CDC, OSHA, and OSAP requirements in all aspects of lab and clinical care, and has an excellent record of exposure prevention. Prior to program entry, all students must comply with health and safety guidelines which include vaccination and/or proof of immunity (positive titer) to hepatitis B, tetanus, diphtheria, pertussis (whooping cough), tuberculosis, poliomyelitis, measles, mumps, rubella, and varicella (chickenpox). Program faculty and dentists are required to maintain current immunizations as well. Should an exposure occur, the program and the college supports the student in testing and follow up care per current CDC and OSHA guidelines. 

Exceptions to immunization requirements are very rare; any concerns must be discussed with the program director as early as possible. 

How to Apply

The Dental Hygiene program is a limited-entry program. The program admits approximately 18 students each fall term through a point-based selection process. Because space is limited, students must meet specific eligibility requirements before applying.
