      both the questions are confusing,as the correct ans given in kap..but it is right
      ans for 1 is B because coeff. of thermal expansion is not same as amalgam and colour stability is same as unfilled resin only that they are not strong enough as filled resin and also unfilled resin have high thermal expansion than filled resin.

      ans for 2 is 2mm

                            1) Which of the folllowing statements describe composite resins
                            I They can be placed and finished in the same appointment.
                            II. They are more color stable than unfilled resins.
                            III. They are similar to Amalgam with respect to coefficient of Thermal expansion.
                            IV. The finished surface tends to be somewhat rough.
                            Answer- A - I , II B. I ,IV C. I, III IV , D. II , III , E. II , III ,IV F. All the above

                            2) Pulpal irritation would not be expected from a restorative material , provided the minimum thickness of the material was
                            A 0.2 mm B. 0.5 mm C. 1 mm D. 2 mm E. 3 mm

                            Dental restorative materials are designed to have coefficient of thermal expansion that are close to that of tooth structure. Amalgam and composite resins have similar coefficients of thermal expansion. The ans is C.

                              I thought the answer for 1) is B too , but the text I am referring to says answer is C .. obviously wrong - just thought to cross check ..
                              4) A young patient receiving endodontic therapy on the maxillary left central incisor. The tooth now is indicated for an esthetic pin retained restoration as interim treatment. Which of the following kinds of pins may be used.
                              I. Self threading pins
                              II Friction lock pins
                              III Serrated cemented pins
                              IV Self shearing pins
                              V. Non serrated cemented pins
                              ANSWER - A. I , III B. I , V C. II , III D. II , V
                              E. III , IV F. III, V

                              On an endo treated tooth there is no need to use any type of pin that require additional drilling (pilot drill) into tooth structure. Serrated pins would be prefered over non serated cemented pins (for retention). In actuality cemented posts are a better alternative.
