Study Notes
Overview of Dental Biomaterials
- Dental biomaterials encompass various substances used to treat, augment, or replace body tissues.
- An interdisciplinary field combining materials science, engineering, biology, and dentistry.
Historical Perspective
- 2500 B.C. – Earliest dental practices by Phoenicians.
- 1728 – Pierre Fauchard recognized as the "Father of Modern Dentistry."
- 1919 – First specification for dental material (dental amalgam) established.
- 1944 – Introduction of controlled fluoridation of water.
- 1976 – Medical Device Amendments to U.S. Food, Drug and Cosmetic Act.
Classifications and Standards
- Ideal restorative materials should show optimal physical, mechanical, chemical, and biological properties.
- Specifications, or standards, set benchmarks for evaluating dental materials.
- Major standards organizations include:
- International Organization for Standardization (ISO)
- American National Standards Institute (ANSI)
- ANSI/ADA specifications are reviewed every five years to ensure safety and efficacy.
Regulatory Framework
- Dental biomaterials fall under the U.S. Food and Drug Administration (FDA) as devices, which do not require the same rigorous evaluation as drugs.
- Manufacturers seeking the ADA Seal of Acceptance must submit clinical data and comply with Good Manufacturing Practices.
Dental Materials and Measurement
- Dental biomaterials are classified into various types based on their usage in restorative dentistry.
- Understanding and utilizing metric (SI) units is crucial for precise measurement in materials science.
- Base SI units include:
- Length (meter, m)
- Mass (kilogram, kg)
- Time (second, s)
- Base SI units include:
Importance of Dental Materials Research
- Ongoing research across dental schools, laboratories, and clinical studies promotes the advancement of dental biomaterials.
- Techniques such as scanning electron microscopy and atomic force microscopy allow for advanced property testing of dental materials.
Future Directions
- Continued emphasis on innovation in dental biomaterials is essential to enhance clinical outcomes and improve restoration longevity.
