EBD Educational Tutorials

Below you will find a number of tutorials developed by the ADA Center for Evidence-Based Dentistry. The first module consists of a number of video tutorials that run 5 to 8 minutes each. The modules are designed for dental or healthcare professionals or students, and are intended to help you understand the basics of EBD.

For more advanced training in EBD, consider attending the ADA-hosted EBD Champions Conference and the Advanced EBD Workshop: Assessing the Quality of Evidence.

Module 1: EBD Overview

This series is designed to help you more fully understand what evidence-based dentistry is and how to apply scientific evidence to your practice.
Title Time  

Lesson 1: What is EBD?
In this lesson, you will learn that evidence-based dentistry (EBD) is a three-part approach to making clinical decisions. It includes (1) an understanding of the patient's treatment needs and preferences, (2) recognition of your own clinical expertise, and (3) evaluation of the best available scientific evidence.

Lesson 2: Navigating this EBD website - for the clinician
In this lesson, you will learn how to navigate the EBD website to find systematic reviews and summaries, ADA clinical recommendations, and other EBD resources.

Lesson 3: Navigating this EBD website - for your patients
In this lesson, you will learn how to help your patients navigate the EBD website to find plain language summaries of systematic reviews and other consumer- and patient-oriented resources on oral health topics.

Module 2: Series on Statistics

This module consists of five tutorials and is designed to provide a basic understanding of the statistics-related concepts you will encounter in evidence-based research and systematic reviews.
Title Time  

Lesson 1: What is null hypothesis?
In this lesson you will develop a null hypothesis and recognize the null hypothesis in systematic reviews.

Lesson 2: Why do we need statistics?
In this lesson you will describe three situations that can be quantified using statistics and identify what the authors of a systematic review are trying to quantify.

Lesson 3: What are the different types of data?
In this lesson you will distinguish between nominal, ordinal and quantitative data as well as identify the type of data being presented in a systematic review.

Lesson 4: What is a p-value?
In this lesson you will learn that the p-value is a mathematical expression of the strength of the evidence against the null hypothesis.

Lesson 5: What is a confidence interval?
In this lesson you will learn that confidence intervals are a range of values that give a clear idea of the magnitude of any potential clinical benefit.
