Title: Oral Environment and Patient Considerations
Course: DES 1100 Dental Materials > Section: Module 2 - Oral Environment and Patient Considerations

Introduction

This module will provide the dental hygiene student with an understanding of properties that dental materials must possess in order to withstand the oral environment. The ways in which different types of stress, moisture, acid levels, and temperature affect dental materials will be described.

Dental hygienists should have an understanding of the types of stress that occur in the oral cavity and the effects of this stress on dental materials. This knowledge allows the dental hygienist to identify dental materials that may be deteriorating and in need of repair or replacement. Knowledge of the physical and mechanical properties of dental materials is important and helpful when conducting patient assessment and treatment.

Objectives

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

- Describe the effects of moisture and acidity on dental materials.
- Describe microleakage and how the results of this process can lead to recurrent decay and postoperative sensitivity.
- Define biocompatibility, and discuss why requirements for biocompatibility may fluctuate.
