The following are features of Titanium alloy except self passivation occurs poor compatibility with PMMA high co efficient of friction higher elastic modulus compared to CoCr alloy high notch sensitivity is high (Question 1 of 10)2. Galvanic Corrosion is most likely to occur in the following couple? Stainless steel and zirconium Stainless steel and cobalt alloy Cobalt alloy and zirconium Cobalt alloy and titanium alloy Titanium alloy and zirconium (Question 2 of 10)3. The following alloy does not generate reactive oxygen species in vivo Aluminium Chromium Cobalt Titanium Nickel(Question 3 of 10)4. Though titanium is an extremely reactive metal, it is one of the most biocompatibile metals for the human body because Titanium forms a stable oxide coating Titanium alloys are less reactive than pure metal In physiological conditions its reactions are inhibited Titanium gets an insulatory covering by proteins Titanium does not react with anything in the human body (Question 4 of 10)5. Torsional Force leads to which of the following fracture? Oblique fracture Spiral fracture Compression fracture Transverse fracture Avulsion fracture(Question 5 of 10)6. Arrange the following alloys in decreasing order of modulus of elasticity(stiffest to most elastic) (1) titanium,(2) stainless steel,(3)Co-Cr,(4) polyethylene,(5) cortical bone (1) polyethylene,(2) cortical bone,(3)titanium,(4) stainless steel,(5) Co-Cr (1) stainless steel,(2)titanium,(3)cobalt-chromium, Co-Cr(4) polyethylene,(5) cortical bone (1)polyethylene,(2) cortical bone,(3) Co-Cr(4)stainless steel,(5)titanium (1) Co-Cr(2) stainless steel,(3) titanium,(4) Cortical bone,(5) polyethylene (Question 6 of 10)7. The material property that refers to the ability of a material to absorb relatively large amounts of plastic deformation before failing is Fatigue strength Toughness Stress relaxation Ductility Brittleness(Question 7 of 10)8. Which of the following is false about Anabolic steroid use in athletes? Athletes who use steroids can experience withdrawal symptoms when they quit ‘Cycling’ refers to dosing of steroid in cycles of weeks or months, with a short break between "Pyramiding," involves slowly increasing the number, the amount or the frequency of steroids to reach a peak and then gradually tapering the amount and frequency of the drug. ‘Stacking’ refers to taking different types of steroid at the same time. Anabolic steroids have no negative cardiac side effects but, it worsens liver diseases(Question 8 of 10)9. A female athlete requested her doctor to prescribe creatine monohydrate capsules as she wanted to build her physique. What side effect among the followings is she likely to develop? heat intolerance Diabetes osteoporosis myopathy amenorrhoea (Question 9 of 10)10.
