Dental materials are specially fabricated materials, designed for use in dentistry. The electrolyte can be water or some other electrolyte, like saliva in oral environment. It is a measure of its potential to deform under small static load. A) The maximum amount of stress a material can withstand without breaking is known as the proportional limit. Fluorescence– When an object absorbs light of a shorter wavelength and emits light of higher wavelength, it exhibits a property of fluorescence, the natural tooth has this property and this contributes to brightness and vital appearance of the human tooth. Above the proportional limit a material function in a plastic manner, while below the proportional limit it behaves as an elastic B. Strain is defined as : A. Among the usual dental materials, ceramics exhibit the lowest adhesive capability due to their inert surface. Tarnish is surface discoloration whereas corrosion is actual deterioration of the metal. Physical Properties Mcqs: 9. Then phenomenon to remember Provides you a guide about the health and care queries that you need in day to day life. Viscosity is the resistance of a liquid to flow, this property comes into play when we deal with materials in the fluid state and depending upon their viscous behavior, materials can be broadly classified into 4 groups. Metamerism– Objects matched under one type of light do not match under other light sources. Physical properties include. Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (dental cavities), but also tooth wear and dental trauma. 5 0 obj 774 endobj stream << Scaling and Root Planing (Deep Teeth Cleaning), Foramen Cecum of Tongue: Anatomy, Significance, Abnormality and Treatment, Pain on Mouth Opening: Reasons, Diagnosis, Home Remedies, and Treatment, Trench Mouth: Symptoms, Causative Agents, Factors, Diagnosis, Home Remedies, Treatment and Prognosis. 1 0 obj >> (A) Viscosity Structural and Stress Relaxation Creep and Flow Color and Color Perception Thermo-physical Properties Tarnish and Corrosion Physical properties are based on laws of mechanics optics , acoustics, thermodynamics ,electricity , rheology , magnetism , radiation ,atomic structure and nuclear phenomenon etc. /Resources<< /Type /XObject Aspirins Comparative evaluation of mechanical properties of dental.
