RESEARCHERS GROW TEETH
IN LABORATORY! |
| A team of Boston scientists has grown strikingly
accurate versions of natural teeth in the lab, raising the possibility
that dentists can eventually do away with devices such as dentures, Bridges
and Crowns. The scientists, of Boston's Forsyth Institute are said to be first to coax such a complex
tooth structure from a collection of individual cells. |

"This is exciting, and I don't think that it's expected," said R. Bruce Donoff, dean of Harvard School of Dental Medicine. The team have already grown batches of
very small tooth crowns, and hope the new technique could be used to grow
larger, more complete teeth It would be at least a decade until patients could be helped, it is estimated.
The research, which was done using pig cells, demonstrate that dental stem cells - primordial cells -
that differentiate into the various structures of the tooth -- readily can
be manipulated. |

Using a section of pig jaw and removing the
a molar that had not yet erupted, they ground this tissue into small
pieces and treated it with enzymes to break it down into small patches of
cells, according to Conan S. Young, a scientist on the project.

The cells were then placed into a soft, porous
structure and implanted into rats, periodically x-raying them to monitor the
growth of small crowns.
The results of the experiments will be published in the October issue of the Journal of Dental Research [JDR}.

“I want the tooth pulled
and I don't want Novocain or gas because I'm in a hurry,” the wife
said to the dentist. “Just pull the tooth safest as possible, and well be on our way.” The dentist was impressed. “You certainly are a brave woman,” he said. “Now which tooth is it?”
Whereupon the woman turned to her husband and said, “Show him your tooth, dear!”

Tower of Dentistry Wears a Golden Crown - 20 floors of mostly dental laboratories and dentists'suites.
|
|
Williamsburg Savings Bank building is Brooklyn's tallest colossus, a 34-story casts shadow on the crossroads
of Flatbush & Atlantic Avenues, a good 400' above the vicinity; visible
from Jersey Shore. The tower at 1 Hanson Place, is an everyday mystery. Most
locals never set foot in it. Those who do know what riches it holds - including 20floors of mostly dental laboratories and dentists' suites, and may wonder
how it got that way. |

Architecture buffs wonder "Why a Golden Renaissance style dome atop a modernist skyscraper?" Literalists wonder why the building
is not in Williamsburg! Owners of homes nearby look at what was once
the largest four-faced clock in the world - and wonder why such a celebrated
timepiece so often provides wrong time! (Prevailing winds turn out to be the culprits.)

The upper-floors labs and dental operatories view New York City and waters and lands beyond, providing welcome, if incomplete, distraction for staff and patients.

The building, opened, in 1929,has
some 20 upper floors rented to dentists and dental labs. Some believe Labs
and Dentists may not be most glamorous tenants, but the field is recession-proof. Rents, more than $45 a square foot are some of the highest inthe area, said William real estate broker. The upper-floor labs and
dental operatories view New York City, waters and lands beyond, a welcome if incomplete distraction for
staff and patients!
