The following are features of Titanium alloy except poor compatibility with PMMA self passivation occurs higher elastic modulus compared to CoCr alloy high co efficient of friction high notch sensitivity is high (Question 1 of 10)2. Though titanium is an extremely reactive metal, it is one of the most biocompatibile metals for the human body because Titanium alloys are less reactive than pure metal Titanium forms a stable oxide coating Titanium does not react with anything in the human body Titanium gets an insulatory covering by proteins In physiological conditions its reactions are inhibited (Question 2 of 10)3. Arrange the following alloys in decreasing order of modulus of elasticity(stiffest to most elastic) (1)polyethylene,(2) cortical bone,(3) Co-Cr(4)stainless steel,(5)titanium (1) stainless steel,(2)titanium,(3)cobalt-chromium, Co-Cr(4) polyethylene,(5) cortical bone (1) titanium,(2) stainless steel,(3)Co-Cr,(4) polyethylene,(5) cortical bone (1) Co-Cr(2) stainless steel,(3) titanium,(4) Cortical bone,(5) polyethylene (1) polyethylene,(2) cortical bone,(3)titanium,(4) stainless steel,(5) Co-Cr (Question 3 of 10)4.

Torsional Force leads to which of the following fracture? Avulsion fracture Transverse fracture Spiral fracture Compression fracture Oblique fracture(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 Brittleness Stress relaxation Ductility Fatigue strength Toughness (Question 7 of 10)8. Galvanic Corrosion is most likely to occur in the following couple? Cobalt alloy and titanium alloy Titanium alloy and zirconium Stainless steel and cobalt alloy Stainless steel and zirconium Cobalt alloy and zirconium (Question 8 of 10)9. Which of the following is false about Anabolic steroid use in athletes? ‘Stacking’ refers to taking different types of steroid at the same time. ‘Cycling’ refers to dosing of steroid in cycles of weeks or months, with a short break between Athletes who use steroids can experience withdrawal symptoms when they quit "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. Anabolic steroids have no negative cardiac side effects but, it worsens liver diseases(Question 9 of 10)10.
