Physical and Chemical Properties of Dental Materials

This book explains the physical and chemical properties of dental materials and their importance in clinical dentistry. It begins with the classification of dental materials (metals, ceramics, polymers, and composites), the requirements of an ideal material, and the challenges posed by the oral environment such as temperature changes, saliva, pH fluctuations, and mechanical forces. The physical properties discussed include mechanical properties (strength, elasticity, hardness, toughness, and fatigue), thermal properties, electrical properties, optical properties, rheological behavior, dimensional stability, and surface characteristics. These properties determine how materials perform under functional and environmental stresses in the mouth. The chemical properties section covers corrosion, tarnish, solubility, sorption, chemical stability, setting reactions, and biocompatibility. These factors influence the longevity, safety, and clinical success of dental restorations and prostheses.
