Classroom courses are only a portion of the University of Southern Indiana's Bachelor of Science in Dental Hygiene curriculum. Clinical and laboratory training is also provided. Classes sizes are small. A true test of what students learn occurs in real life dental care settings during community dental health sessions. These sessions take place at the university's onsite dental clinic. To broaden their learning, students can also get a certificate in dental assisting or local anesthesia for dental hygienists. Credits from certificate programs may be transferrable into the four-year option.
