Course Overview

This in-person course will prepare the dental assistant to take the Missouri Test of Basic Dental Assisting Skills (MBDA), which is a pathway in Missouri to becoming certified in Expanded Functions. Topics discussed will follow the DANB exam outline, which includes questions on oral disease prevention; dental materials; medical emergencies; charts/legal/jurisprudence; radiation health and safety; infection control; and, tooth morphology. 

PLEASE NOTE: This is a REVIEW ONLY of the Missouri Basic Skills Exam. 

Course Format & Study Aides

During this course, the group will have open dialogue about common topics covered on the exam. Each assistant will be provided a set of topical flashcards. The group will discuss each topic, while assistants make their own notes on each flashcard, which can be used later for self-study and review. After the initial review and discussion, a practice test will be given to each assistant. After completion, assistants will self-grade tests openly, while allowing for additional Q&A time on topics that may need deeper analysis. After completion, the practice test will serve as an additional study guide for the assistant. In addition, a short overview of the EFDA programs and processes will be given at the conclusion of the program, including time for Q&A.

Course Objectives 

  • Thorough review and discussion of the topics included in the DANB MBDA exam
  • Focus on the challenging topics and questions many dental assistants have difficulty with
  • Complete provided flashcard set for additional study and review
  • Take practice test (self-graded in class) to serve as an additional exam study guide
