Mosby’s review questions for the national board dental hygiene examination. The book is in great condition. The cover has a little wear as you can see in the photos. There are tabs that have been attached to quickly reference to different areas of the book. I have included a video of the inside of the book. There’s no writing in the book except for one teeny tiny spot. The online code has not been revealed either. This is a great study guide for the dental hygiene national board.
