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

Water can also wick up from the soil in the ground proximity test, further keeping the boards wet and potentially providing some nutrients essential for decay.

44% of under-fives in North Wales have tooth decay.
It has many uses, but the best is on very early decay where as little as 20 seconds can heal the tooth, avoiding the need for a filling and making the tooth stronger than ever".
Based on these analyses, the researchers conclude that tooth decay is not strongly linked to lead exposure, but they cannot rule out that a weak association exists.
Representing the alliance, British Dental Association chief executive Mr John Hunt said: "Tooth decay is preventable, and in areas where decay rates are high, water fluoridation would cut disease levels in half.
We are thrilled that Smiles Across Minnesota will now be able to help keep children free of tooth decay, which is almost entirely preventable," said Liz Rogers, director of communications for Oral Health America.
Professor Monty Duggal, an author of the review, said that it's not enough to just look at what we eat when talking about tooth decay, as other factors seem to be as important.
