TOOTH PASTE

Toothpaste from a tube being applied to a toothbrush Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis)

Ingredients[edit] In addition to 20–42% water, toothpastes are derived from a variety of components, the three main ones being abrasives, fluoride, and detergents.

Abrasives constitute at least 50% of a typical toothpasteRepresentative abrasives include particles of aluminum hydroxide (Al(OH)3), calcium carbonate (CaCO3), various calcium hydrogen phosphates, various silicas and zeolites, and hydroxyapatite (Ca5(PO4)3OH). The abrasive effect of toothpaste is indicated by its RDA value. Too high RDA values are deleterious. Some dentists recommend toothpaste with an RDA value no higher than 50 for daily use. Fluoride in various forms is the most popular active ingredient in toothpaste to prevent cavities.The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones. Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF2), olaflur (an organic salt of fluoride), and sodium monofluorophosphate (Na2PO3F) are also used. Stannous fluoride has been shown to be more effective than sodium fluoride in reducing the incidence of dental caries[4] and controlling gingivitis, but causes somewhat more surface stains.Many, although not all, toothpastes contain sodium lauryl sulfate (SLS) or related surfactants (detergents). Triclosan or zinc chloride prevent gingivitisIncluded are various sugar alcohols, such as glycerol, sorbitol, or xylitol, or related derivatives, such as 1,2-propylene glycol and polyethyleneglycol.

Pioneers in Dentistry :

Dr. Rafiuddin Ahmed " Father of Modern Indian Dentistry"

Dr. Rafiuddin Ahmed (1890-1965) was born on December 24, 1890, in Bardhanpara, East Bengal, India. He graduated from Aligarh Muslim University in 1908. By the next year, he left for the United States by working his passage over.He enrolled in the University of Iowa School of Dentistry, earning his dental degree in 1915. Dr. Ahmed then worked in the Forsyth Dental Infirmary for Children in Boston, Massachusetts, until 1918. In 1919, he returned to India to open a dental practice in Calcutta.

Dr. Ahmed’s philosophy was: ‘‘Education is the responsibility of the State; but if no one is willing to carry the cross, I will, for as long as I can.’’ In 1925, Dr. Ahmed established the Bengal Dental Association, which became the forerunner for the Indian Dental Association(which he also organized in 1928). He served three terms as President of the Indian Dental Association from 1945 to 1949. He also established the Indian Dental Journal in 1925 and was its Editor until 1946.Dr. Ahmed was awarded a Fellowship in the International College of Dentists in 1947 and Fellowships in the Royal College of Surgeons of England and the Pierre Fauchard Academy in 1949. In 1964, the Indian government awarded him the Padma Bhushan

The First Dental College of India affiliated with the State Medical Facility in 1936, and then with the University of Calcutta in 1949. In that same year, Dr. Ahmed donated his First Dental College of India to the West Bengal government. Dr. Ahmed served as the Principal of the College from 1920 to 1950.

He also established the Indian Dental Journal in 1925 and was its Editor until 1946. Dr. Ahmed published the First Student’s Handbook on Operative Dentistry in 1928.

Today, Dr. R. Ahmed is remembered as the Nestor and Dean of Dentistry, Dental Education, and the Dental Profession in India. He died on January 18, 1965.
Indian Dental Association (IDA) passed a resolution to declare December 24th as National Dentist Day to celebrate birth anniversary of Padmabhushan Dr. R. Ahmed, Hats off to Dr.Rafiuddin Ahmed for his contribution to the field of Dentistry. Courtesy:wikipedia.org

No Longer Worry About Cholesterol in Food


"Genetics appear to be playing a stronger role in heart disease"

A top nutrition advisory committee says people no longer have to be concerned about eating foods that are high in cholesterol. High levels of “bad” cholesterol in the blood, which have been linked to heart disease, are still a health concern. What’s changed is that many researchers and physicians now believe that eating cholesterol-rich foods such as eggs may not affect the cholesterol that is in your blood.
The body creates cholesterol in amounts much larger than what you can eat, Dr. Nissen says. So avoiding foods that are high in cholesterol won’t affect your blood cholesterol levels very much. “About 85 percent of the cholesterol in the circulation is manufactured by the body in the liver,” he says. “It isn’t coming directly from the cholesterol that you eat.”

Research is beginning to show that your genetic makeup – not diet – is the driving force behind cholesterol levels, says cardiologist Steven Nissen, MD.Researchers are beginning to understand in greater depth that the relationship between cholesterol and the body is extremely complicated.
Cholesterol is a waxy substance that ultimately ends up in the walls of arteries. It causes the plaques that lead to heart attacks and strokes. The current U.S. Dietary Guidelines call for a daily cholesterol limit of 300 milligrams.There’s different kinds of cholesterol. Low-density lipoprotein or LDL (bad) cholesterol contributes to plaque buildup along with triglycerides, another lipid. High-density lipoprotein or HDL (good) cholesterol discourages plaque buildup
The greater danger for everyone is in foods that are high in trans fats, Dr. Nissen says.Those often appear on food labels as hydrogenated oils or partially hydrogenated vegetable oil,” Dr. Nissen says. “Those types of fats do tend to raise cholesterol and do tend to increase the risk of heart disease.”However, people with certain health problems, such as diabetes, should continue to avoid cholesterol-rich foods, the report says.
