Editorial :

Evidence of oral hygiene methods  first appear in the archaeological record around 5000 years ago in Egypt, China, Mongolia and India. An Egyptian manuscript dated 4th Centure AD , prescribes salt,pepper, mint leaves and iris flowers mixture as toothpaste.Ziryab, the famous musician of 9th Century is credited with a tooth paste which were famous in Islamic Spain .These pastes were possibly used with the early tooth brushes in the from of neem sticks and miswak which is still prevalent in the Arab world.19th Century saw the advent of tooth brushes in Britian which were either chalk,brick,salt as ingredients.Charcoal was a widely used dentrifice in India.

I will bring in more informaiton on the evolution of tooth pastes in the next issue.

Laughter - The Best Medicine :

The Jacksons were shown into the dentist's office, where Mr. Jackson made it clear he was in a big hurry.

"No fancy stuff, Doctor," he ordered, "No gas or needles or any of that stuff. Just pull the tooth and get it over with."

"I wish more of my patients were as stoic as you," said the dentist admiringly. "Now, which tooth is it?"

Mr.Jackson turned to his wife Becky. "Show him, honey."

DNA - A short Review

Dr.Rasha Seragelden

 Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms.

The main role of DNA molecules is the long-term storage of information and DNA is often compared to a set of blueprints, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.

Chemically, DNA is a long polymer of simple units called nucleotides, with a backbone made of sugars and phosphate groups joined by ester bonds. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription. Most of these RNA molecules are used to synthesize proteins, but others are used directly in structures such as ribosomes and spliceosomes.

Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms such as animals, plants, and fungi store their DNA inside the cell nucleus, while in prokaryotes such as bacteria it is found in the cell's cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins and thereby control which genes are transcribed.

HPV Research Shows Everyone Is At Risk for 6 Oral Cancer

Dental Implants of 3mm Diameter or less are more popular than of higher diameter says a research by Millennium Research Group's US Dental Marketrack.

The US market for small-diameter dental implants grew more than 30% in 2007, Presently the market capitalization  for Smaller Diameter Implants in United states is  over $20 million , which is 30% growth compared to the previous year. The increasing number of general dentists  incorporating dental implants into their list of services has contributed significantly to the rising sales of small-diameter dental implants.Patient preference to smaller diameter Dental Implants due to relatively less chair time and cost effectiveness has been a contributing factor.

Noble Bio-Care Stock Falls by 50%

 

FOR SHAREHOLDERS OF Zurich-based Nobel Biocare (NOBN.Switzerland), the world's leading manufacturer of dental implants, the past 12 months have been like a trip to the oral surgeon: painful and expensive.

The shares, which trade on the Swiss stock exchange and split 5-for-1 Thursday, are down about 50%, to 49 Swiss francs, from a year-ago high of CHF91.40, amid concern about Nobel's sluggish sales growth and its failure to meet earnings guidance. "Revenue growth has declined from 25% in 2005 to 11% last year," says Jeff McCormack, a research analyst at Manning & Napier in Fairport, N.Y., a Nobel investor.
