The following are features of Titanium alloy except high notch sensitivity is high higher elastic modulus compared to CoCr alloy self passivation occurs poor compatibility with PMMA high co efficient of friction (Question 1 of 10)2. The material property that refers to the ability of a material to absorb relatively large amounts of plastic deformation before failing is Brittleness Ductility Stress relaxation Toughness Fatigue strength (Question 2 of 10)3. 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 does not react with anything in the human body Titanium gets an insulatory covering by proteins In physiological conditions its reactions are inhibited Titanium alloys are less reactive than pure metal(Question 3 of 10)4.

Which of the following is false about Anabolic steroid use in athletes? "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. ‘Cycling’ refers to dosing of steroid in cycles of weeks or months, with a short break between Anabolic steroids have no negative cardiac side effects but, it worsens liver diseases Athletes who use steroids can experience withdrawal symptoms when they quit (Question 8 of 10)9.
