High Yield Facts of Oral Pathology by Dr Maryam Malik

In the exam of FCPS Part 1 20-25 MCQs come from the subject of Dental Materials. In our articles we have talked about the Books used for Dental Materials. In order to solve MCQs of Dental Materials you have to study this subject thoroughly. Also you should go through different important points of Dental Materials. We have made important Points of Dental Materials. Try to cover all these points and MCQs of Dental Materials. Hopefully it will be helpful for you in the Exam.
