The PowerPoint PPT presentation: "Physical properties of dental materials" is the property of its rightful owner. Monogr Oral Sci, Basel, Karger. 2) Metallic denture base materials: Metallic denture base material is an advantage because heat transmission causes tissue stimulation through vasodilatation and vasoconstriction of blood vessels of underlying tissues keeping it in a healthy state. The energy that the tooth absorbs is converted into light with longer wavelengths, in this case the tooth actually becomes a light source. PROPORTIONAL LIMIT 6. The high, Metallic denture base material is an advantage, How rapidly the temperature increases in a, Specific heat of metal or alloys is important. Applications of Nanocomposite Materials in Dentistry, 2019, pp. Pallavi Madanshetty 1. And they’re ready for you to use in your PowerPoint presentations the moment you need them. Therefore, some anterior restorative materials and dental porcelains are recently formulated with fluorescing agent to reproduce the natural appearance of tooth structure. ELASTIC LIMIT 7. Acc. Ex. That's all free as well! 3) Scattering : this occurs when light passing through an optical medium redirects some of the radiation into direction other than that of the beam. The high thermal conductivity of amalgam is a disadvantage because if it is near the pulp it may cause patient discomfort as a result of temperature changes produced by hot or cold foods and beverages unless adequate tooth tissue remains or non-metallic substances are placed between the tooth and filling as a base for insulation. This phenomenon is called metamerism. Impression Materials 9.

Specific heat (CP): How rapidly the temperature increases in a material depends upon the specific heat of the material, which is defined as the amount of heat required to raise the temperature of a unite volume by 1°C. Modern fillings material ( cements, amalgam, composition materials). An opaque material either absorbs or reflects all of the light. The ratio of the angle of incidence and sine angle of refraction is a constant called “refractive index”. To view this presentation, you'll need to allow Flash. Nanotechnology is aimed at the fabrication of nanoparticles, nanospheres, nanorods, nanotubes, nanofibers, dendrimers, and dendritic copolymers, each with unique properties which find applications on dental materials. YOUNG’S MODULUS 8. Dental Material. Or joule liberated to convert 1 gm of a material from liquid to solid state. Boasting an impressive range of designs, they will support your presentations with inspiring background photos or videos that support your themes, set the right mood, enhance your credibility and inspire your audiences. Examples of density of some dental materials: a) Acrylic resin = 1.2 gm/cm³ b) Porcelain = 2.4 gm/cm³ c) Gold alloys = 17 gm/cm³ d) Cobalt – chromium alloys = 8 gm/cm³. Applicants must hold either a: 1. Cp = specific heat K = thermal conductivity. Metamerism : the color of objects under one type of light may appear different under another light source. A person with porcelain crowns or composite restorations that lack a fluorescing agent appears to be missing teeth when viewed under a black light . When the liquid is frozen, this is liberated (latent heat of fusion). Cp specific heat, K thermal conductivity. chemistry concepts covered. the resistance of a homogenous conductor of uniform cross section at a constant temperature varies directly with the length and inversely with the cross sectional area of the sample according to the following equation: L R = P -------- A R is the resistance in ohms: P is the resistivity. Density:. This fact is used in TV sets to create a full color picture from only three colored sets of dots. Fluorescence: natural tooth structure absorbs light at wavelengths too short i.e. the most common way of measuring this expansion is by taking a length of material, heating it to a certain temperature and then measuring the resultant change in length. This is presented by the thermal diffusivity, h, such that: K h = --------------- Cp P P = density of material . - Black investigated the properties of amalgams and their possible use for ... amalgam is now used more than any other filling material for the restoration of ... - Bonding of resin-based materials Libyan International Medical University.
