2. the process or stage of decline, as in old age.
3. in radioactivity terminology the disintegration of the nucleus of an inactive nuclide by the spontaneous emission of alpha or beta particles. Called also radioactive disintegration. Substances produced by the disintegrations are called daughter (3) compounds.

Patient discussion about decay

Q. what would be the best way to protect my teeth from decaying?i fill pain always in my private parties,what prb whenever i take long with out sex,so i would like the advice from my fewwol

A. i fail to see the connection between teeth and groin pain...about the teeth. it's very very simple- get used to a healthy oral hygiene. brush your teeth in the right way twice a day for at least 6 minute. use floss. go to a dental hygienist, she'll guide you through it.

Q. Whether it`s possible for Bipolar disorder in children?

A. It is possible for children to suffer with bipolar disorder. It is a tricky diagnosis in children I would strongly suggest professional help when dealing with children with bipolar disorder.
I wouldnt trust the diagnosis of a GP, I would suggest getting a referal to a pediatric psychiatrist for a through evaluation and proper treatment
