Evidence is growing that this âdigit ratioâ, especially when applied to the right hand, is a fundamental indicator of sexuality, aggression and Â­diseases suffered by men. 1  Pointing the finger: Scientists have noticed a relationship between finger measurements and a host of unrelated traits. This week, for example, strong evidence has emerged of a link between the â2D:4D finger ratioâ and a manâs likelihood of developing prostate cancer.
The palatal expander appliance is a specially made device used to widen the upper arch or roof of the mouth. By widening the upper arch, the upper teeth line up better with the lower teeth, giving the patient a better bite. Widening the palate makes room for crowded teeth to align better.
Take small bites and chew gently. Remember, the palate expander is literally separating the two halves of the upper jaw, exerting pressure on the bones of your lower face. You will most likely end up chewing with the teeth that aren't harnessed to the expander. 3. Take small sips and use a thin straw. Liquids will be easier to ingest than solid foods, since your tongue doesn't have to move the food around in your mouth to chew, only to swallow. 4. Wipe your mouth frequently. A mouth with a palatal expander tends to produce a lot more saliva in general. Keeping a napkin or hankie ready to dab away the drool will keep things neat and dry.
