    I need the help of a mathematician.

    This is not game related but I really am trying to figure out a real life question.

    I read in a dentist's office that 80 percent of the people in the US have gum disease and that if a woman has has gum disease she only a one chance in seven of having a healthy baby.

    With those two facts(?) how can one figure number of unhealthy babies out of a 100 will be born each year ? It kind of seems like about 6 babies in 7 will be unhealthy but I don't know how to apply the 80 percent factor to that.

    Hope that makes enough sense so one of you smart guys can give me a number. My guess is around 78.

    TIA for your help

    You need more info. For starters, your need the % of pregnant women with gum disease who take the pregnancy full term.

    You can't. Those "facts" pertain to different populations. That 80 per cent of US population has X tells nothing about the percentage of females of reproductive age having X, and nothing about the percentage of pregnant females having X.

    Meaningless scare tactic by the dentists, impossible to calculate actual odds.

    1. No proportion given for gum disease in men to women
    2. No proportion given for women of childbearing age
    3. No mention of the percentage of women of childbearing age that have gum disease

    If gum disease has a higher prevalence in poorer populations then it is likely this will increase the percentage of unhealthy births.
    However if it is more prevalent in older women who are past their child bearing years or more prevalent in men, then the percentage of unhealthy babies will fall.

    To calculate any meaningful statistic requires all the facts not a sound bite (or in this case many unhealthy bites)

    Gum disease appears to have a high correlation to heart disease and dementia in both men and women, and while the exact reason is still a matter of research, the statistics mean a lot of money is going into the how and why.
    Since that would affect both men and women we should all respect our bodies and take care of our mouths. After all a tooth brush and toothpaste (first line of defence) are not expensive. Avoiding sugary drinks and foods even simpler and cheaper.

    Perfect answer..

    Also, I highly doubt 80% ( seems a bit high ) have gum disease in USA ..Seems like fake news or crap to me. IMHO ( only thing I seen was incarcerated mother study)

    it's funny that most of them believe that fluoride reduces cavities and are ok with it in our drinking water. maybe they secretly want the population stupid so they can keep charging exorbitant prices.

    The only correct answer.

    It was probably an advertorial in which you have read.
    Those are adds disguised as scientific journals.

    Rubbish of course.

    I suggest you read this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6191679/

    Periodontal disease (PD) is an inflammatory disease of the tissues supporting the teeth. PD affects 65 million adults over the age of 30 years in the USA (1–4), and worldwide 5 to 70% of adults. These percentages differ according to the geographical area and the definition of PD (5). Women who develop PD during pregnancy, it’s estimated 1 woman in 5, may have a higher risk of adverse pregnancy outcomes (APOs) (6, 7).

    A higher risk doesn't give you an exact number, but if you dive into "6, 7" (see the links there), you might have an estimated guess. Thanks for the question, had an interesting search and read
