Study Notes

Definition and Scope of Dental Materials

  • Dental materials are specially fabricated materials designed for use in dentistry.
  • The science of dental materials involves studying composition, properties, and environmental interactions.

Characteristics of Oral Environment

  • Oral environment is characterized by:
    • Wet conditions (saliva, food, and drinks)
    • Temperature fluctuations (ice cream to coffee/tea)
    • pH variations (neutral to acidic/alkaline)
    • Masticatory forces variation

Ideal Dental Materials

  • Biocompatibility and safety (nontoxic, non-irritating, non-allergic)
  • Mechanically stable and durable (withstands biting and chewing forces)
  • Dimensionally stable (minimally affected by temperature or solvents)
  • Easy manipulation (easy use with no special equipment)
  • Tasteless and odorless
  • Cleanable (can be maintained)
  • Resistant to corrosion or chemicals (does not deteriorate over time)
  • Cost-effective (within patient's budget)

Classification of Materials Used in Dentistry

  • Based on chemical composition, there are four classes of materials:
    • Polymers
    • Metals
    • Ceramics
    • Composites (mixture of two or more of the above classes)

Polymers

  • Polymers are macromolecules built up by linking together smaller molecules (monomers)
  • Process of linking repeating units (monomers) is termed polymerization
  • Examples: polymer molecules formed from monomers through polymerization
