"I love to use stories from the dental offices I have worked for in the past - whether funny, sad, embarassing or inspirational. The students get a kick out of the things we tell them and it seems to bring the text to life if they have a story to relate to it." - Julianna K., Intra Oral Dental Assistant Instructor
