Interesting: Alligators offer model for human tooth replacement

American alligators might serve as suitable models to study tooth replacement in human adults, according to a new study in Proceedings of the National Academy of Sciences (May 13, 2013).

To uncover molecular mechanisms of tooth renewal, Cheng-Ming Chuong, MD, PhD, from the University of Southern California and an international team of colleagues studied repetitive tooth formation in American alligators. Because alligators have well-organized teeth with morphological traits similar to those of mammalian teeth — such as secondary palates and implantation in sockets of the dental bones — and are capable of lifelong tooth renewal, the authors reasoned that the long-lived reptiles, which can replace each of their 80 teeth up to 50 times, might serve as models for mammalian tooth replacement.

Through a combination of histological, molecular, and imaging techniques, the researchers found that each alligator tooth is a complex unit of three components in different developmental stages that are structured to facilitate replacement once they are dislodged. They found that at an early tooth development stage, the alligator dental lamina forms a bulge at its distal tip that houses putative, quiescent stem cells. Molecular analysis revealed that the initiation of the tooth cycle corresponds with the dynamic expression of an array of signaling molecules implicated in tooth development.

According to the authors, the findings might aid efforts to trigger tooth renewal in human adults who have lost teeth or to curb uncontrolled tooth development in people with supernumerary teeth.

Official: New Delhi venue for 2014 FDI congress

Geneva and New Delhi, 6 May 2013:

FDI is pleased to announce that its 2014 Annual World Dental Congress will be held in New Delhi, India, from 11 to 14 September. It will be organized jointly by FDI and its national member, the Indian Dental Association.

This will be the second Annual World Dental Congress to take place in India. The first was held in New Delhi in 2004.

“We are delighted that FDI has once again chosen India for its landmark event – it is a wise choice,” said IDA President Dr Pramod Gurav. “Today, India is a land of opportunity in dentistry: awareness of oral health is on the increase and access to care is widening rapidly. This is good news for the country’s dentists, its burgeoning dental industry and for the success of the 2014 congress.”

FDI President Dr Orlando Monteiro da Silva echoed Dr Gurav’s comments, adding: ”FDI’s mission is to lead the world to optimal oral health – and where better to pursue that mission than in one of the world’s largest economies and most populous countries? The New Delhi 2014 Annual World Dental Congress is good for India and good for FDI!

FDI New Delhi 2014 will follow on from the already record-breaking 2013 Annual World Dental Congress to be held in Istanbul from 28 to 31 August and the highly-successful celebratory 100th anniversary congress in Hong Kong in 2102.
