    True or false? Corrosion of dental amalgam helps to reduce microleakage.
    The answer is true.But why true?
    I think the corrosin may cause microleakage.
    Can somebody answer the question?

    Pre-dent forum is the wrong place to ask questions about actual dentistry.

    We can without a doubt tell you what the best school is though. :rolleyes:

    No worries, and the school thing was a joke. The dental forum might be better able to answer your question: http://forums.studentdoctor.net/forumdisplay.php?f=18

    Check out this article:
    A review on Dental Amalgam Corrosion and Its Consequences by M. Fathi PHD and V. Mortazavi DDS.

    The article basically states that corrosion of the amalgam occurs between the tooth and the restoration. The empty space prior to corrosion allows for microleakage. The accumulation of the electrolytes and crevice corrosion seals up this space making a self sealing restoration. So it appears at first there is microleakage, but when corrosion occurs, the space is sealed up.

    Amalgam expands during the process of corrosion (oxidation), thereby reducing microleakage.

    True, and after a lot of debate we determined the consensus was that UoP and the U of Minnesota were the two best in the nation.

    Alslamo alykom (It means peace be upon all of you).It is not important where I came from.I am only polite because I am a muslim sister and Islam teaches me to be polite and Allah (my lord) rewards me much if I deal with people in polite way and kind way even if they had not the same faith (Islam).
    The prophet Mohammed said:"I am sent to complete the molarity".
    I am so happy also to join this forum and now I became one of the dental family,I came here to make my education better and sure all of you will help me to learn more and more and this also makes me happy as Allah rewards much the muslim who works hard to make anything makes the earth better and learn the science and islamic studies.Also the prophet Mohammed (peace be upon him) told us that "Allah likes if some body works and become efficient in it".
    Peace be upon the prophet Mohammed and peace be upon the whole prophets sent by Allah (Jesus,Moses,David,Noah,Ibrahim).
    Ameeeeeeeeeeeeen.
    We will not speak more about that as this is not the right place to speak about Islam in this forum so we have to respect this.If somebody want to know about Islam enter this link.

    May Allah guide all of us (Ameeeeeeeeeeeeeeen).

    Oh wow!your site is so good sir thanks so much for all of your effort.I added it to my favourites and I hope to benifit much from it.Peace be upon you.

    I like to say something.I am muslim and I hope to see peace in the world and Islam teaches the person to be peaceful and tolerant and you can know this all in the Quraan.Allah said in the Quraan:"O,Mohammed if they want peace be peaceful with them".

    Also if you read about the biography of the prophet Mohammed you will know always that he want peace but the others want the war.So he had to stant in front of them only to defend himself and the muslims.

    Immagine also the greetings of Islam is peace be upon you.So Islam is a religion invite the people to peace.
    But about terrorists (they are people have no religion) because if these people were really good muslims or christians they wouldn't herror people.Islam is peacful and also Christianity is peaceful.And also you have not to believe all you see and hear to the people who tell lies about Islam or the muslims who wear the title of muslims but they don't practise Islam.
    So,if somebody wants to know about Islam,I showed you the link to know Islam from its origional sources.
    There is no relation between Islam and terrorism.
    And there is no compultion in religion.
    May Allah guide us all Ameeeeeeeeeeeeeeeeen.
    May be wake up one day we find no terrorism in the world and all peace and only peace Ameeeeeeeeeeeeen.
