health found affecting cognition, too
By the American
Geriatrics Society news staff
Maintaining good oral health may help older adults
prevent a variety of health problems and
disabilities. However, the effect of tooth loss on
physical or cognitive health and well-being is
In a study published in the Journal of the
American Geriatrics Society, researchers explored
this connection. To do so, they examined
information from the Japan Gerontological
Evaluation Study project.
In their study, the research team examined
information from more than 60,000
community-dwelling people aged 65 and older and
who did not meet the Japanese criteria for needing
The participants were given questionnaires to
The researchers learned older adults who have
significant tooth loss are less functional when
compared with people who lose fewer teeth.
The research team suggested that it is essential
that older adults receive the support they need to
maintain good oral health self-care practices, and
that they receive adequate dental care.

fillings found to repair teeth, too
By the Queen Mary
University of London news staff
A new research report says that new
bioactive glass composite might actually
repair took decay.
The report comes from Robert Hill, chairman of
physical sciences at the Institute of
Dentistry at Queen Mary University of London.
Over 80 percent of the population in the
United Kingdom has at least one filling, with
seven being the average while eight million
cavities are filled with amalgam each year.
The research data said that bioactive repair
of tooth decay prolonged the life of composite
fillings and reducing the need for
mercury-based amalgams, The report is being
called a significant step forward in
tooth restorative materials.
Hill outlined how the new bioactive glass
composites are unique in their ability to
release fluoride as well as the significant
quantities of calcium and phosphate that are
needed to form tooth mineral.
Hill explained that while current dental
fillings include inert materials, the data on
the new bioactive glass composite shows that
it interacts positively with the body
providing minerals that replace those lost to
“Our scientists and dentists at Queen Mary
University of London replaced the inert tooth
filling materials with our new bioactive
glass,” said Hill. “Not only did this
bioactive glass composite remineralize the
partially decayed teeth, but it also creates
an alkaline environment that discourages the
bacteria that caused the initial decay.
“The new bioactive glass also fills in the
gaps with tooth mineral thus preventing the
oral bacteria which cause tooth decay from
establishing themselves. Research in the U.S.
suggests this will potentially prolong the
life of fillings and slow secondary tooth
decay because the depth of bacterial
penetration with bioactive glass fillings was
significantly smaller than for inert
