Mechanical Properties Of Dental Materials Write a short note on flexibility and resilience. Answer: Flexibility: Generally in dental practice, the material used as a restoration should withstand high stresses and show minimum deformation. However, there are instances where a large strain is needed with moderate or slight stress. For example, in an orthodontic … [Read more...] about Mechanical Properties Of Dental Materials
Drugs Acting On Central Nervous System Sedatives And Hypnotics
Drugs Acting On Central Nervous System Sedatives And Hypnotics Introduction In general, sedative-hypnotics are drugs used to slow down mental and physical functions of the body. These are also referred to as CNS depressants. Sedatives are chemical agents that tend to produce a calming effect, relax muscles, and relieve feelings of tension, anxiety, and irritability … [Read more...] about Drugs Acting On Central Nervous System Sedatives And Hypnotics
Drugs Acting On Central Nervous System
Drugs Acting On Central Nervous System General Anaesthetics General anaesthetics are CNS depressants which cause partial or complete loss of consciousness, sense or pain. The effect is reversible and generally used to produce unconsciousness during painful surgeries. General anaesthetics bring about the descending depression of the CNS, starting with the cerebral cortex, … [Read more...] about Drugs Acting On Central Nervous System
Understanding Passivation In Dental Alloys
Understanding Passivation In Dental Alloys Write a short note on the passivation of metals. Answer: Passivation of metals: Certain metals readily form strong adherent oxide films on their surface which protect them from corrosion. Such metal is said to be passive. Chromium, titanium, and aluminum are examples of such metals. If more than 12 % chromium … [Read more...] about Understanding Passivation In Dental Alloys
Molecular Representations And Nomenclature
Molecular Representations And Nomenclature Molecular representations From the beginning of chemistry, scientists have devised means of representing the materials they are discussing and have gradually developed a comprehensive range of shorthand notations. These cover the elements themselves, the bonding between atoms, the arrangement of atoms in molecules, and, of course, … [Read more...] about Molecular Representations And Nomenclature
