Complete + DH Dental Hygienist National Examination Complete Guide 2025 This is study material for dental hygienists (DH). Some of the materials have writing in them, while others do not. Important parts are highlighted with markers and have notes written in them. I have also written in changes that were made with the new year, so I think it will be helpful for the national examination. I passed the 34th exam! I hope the notes are helpful too ‎☆ Please refrain from purchasing if you are sensitive to used items. Thank you for looking. #DentalHygienist #NationalExamination #DentalHygienistTextbook
