Title: Module 2 Introduction
Course: DEH 1720 Dental Hygiene Course > Section: Module 2 - Dental Plaque Biofilm

Introduction

In this module, the concept of dental plaque biofilm will be addressed. The definition of dental plaque biofilm, along with how this biofilm is formed, and the various types of bacteria involved in the formation are also included. Dental plaque can become calcified and convert into dental calculus. The way in which dental calculus attaches to the teeth and ways to inhibit the formation of calculus will be covered.

Dental plaque is involved and is the etiology of many dental diseases. The dental hygienist student should be knowledgeable in the formation and the consequences of inadequate removal of this biofilm. The dental hygiene student should have an understanding of this foundational information when studying to become primary preventive specialists.

Objectives

Upon completion of this module, the student will be able to:

- Distinguish between primary and secondary bacterial colonizers in dental plaque, and cite examples of each.
- Identify the primary sites of calculus formation, explain how calculus forms, and detail the differences between supragingival and subgingival calculus.
- Describe the basis for the involvement of the acquired pellicle, bacterial dental plaque, and dental calculus in caries and the inflammatory periodontal diseases.
