The word pyorrhea (alternative spelling: pyorrhoea) comes from the Greek pyorrhoia (πυόρροια), "discharge of matter", itself from pyon, "discharge from a sore", rhoē, "flow", and the suffix -ia. In English this term can describe, as in Greek, any discharge of pus; i.e. it is not restricted to these diseases of the teeth. Economics
It is estimated that lost productivity due to severe periodontitis costs the global economy about US$54 billion each year. Other animals
Periodontal disease is the most common disease found in dogs and affects more than 80% of dogs aged three years or older. Its prevalence in dogs increases with age, but decreases with increasing body weight; i.e., toy and miniature breeds are more severely affected. Recent research undertaken at the Waltham Centre for Pet Nutrition has established that the bacteria associated with gum disease in dogs are not the same as in humans. Systemic disease may develop because the gums are very vascular (have a good blood supply). The blood stream carries these anaerobic micro-organisms, and they are filtered out by the kidneys and liver, where they may colonize and create microabscesses. The microorganisms traveling through the blood may also attach to the heart valves, causing vegetative infective endocarditis (infected heart valves). Additional diseases that may result from periodontitis include chronic bronchitis and pulmonary fibrosis. Footnotes

Alcohol exposure in a developing fetus can result in slowed development of the fetal brain, resulting in severe retardation or death. Surviving infants may have severe abnormalities such as abnormal eyes, fissures, lips and incomplete cerebella. Some infants may develop lung disease. It is even possible that the baby throughout pregnancy will develop heart defects such as ventricular septal defect or atrial septal defect. Experts suggest that pregnant women take no more than one unit of alcohol per day. However, other organizations advise complete abstinence from alcohol while pregnant. Adolescence
Adolescence and the onset of puberty have both a physiological and social impact on a developing person. About half of grade 12 students have been drunk, and a third binge drink. About 3% drink every day. One of these social impacts is the increase in risk-taking behaviors, such as the emergence of alcohol use. Children aged 16 and under who consume alcohol heavily display symptoms of conduct disorder. Its symptoms include troublesome behaviour in school, constantly lying, learning disabilities and social impairments.Alcohol abuse during adolescence greatly increases the risk of developing an alcohol use disorder in adulthood due to changes to neurocircuitry that alcohol abuse causes in the vulnerable adolescent brain. Younger ages of initial consumption among males in recent studies has shown to be associated with increased rates of alcohol abuse within the general population.Societal inequalities (among other factors) have influenced an adolescents decision to consume alcohol.
