NEW STUDY: BIOACTIVE GLASS
PROLONGS THE LIFE OF TOOTH
A new study in the journal Dental Materials shows that
bioactive glass inhibits bacterial decay and promotes
remineralization when used in tooth fllings
Engineers at Oregon State University (OSU) have made
promising fndings about the ability of bioactive glass to
help reduce the ability of bacteria to attack composite
tooth fllings—and perhaps even provide some of the
minerals needed to replace those lost to tooth decay.
Te new research was published in the journal Dental
Materials, in work supported by the National Institutes of
Health. (Editor’s note: You can view the study here.)
“Bioactive glass, which is a type of crushed glass that
is able to interact with the body, has been used in some
types of bone healing for decades,” said Jamie Kruzic, a
professor and expert in advanced structural materials
and biomaterials in the OSU College of Engineering.
Bioactive glass is made with compounds such as
silicon oxide, calcium oxide, and phosphorus oxide, and
looks like powdered glass. It is called “bioactive” because
the body notices it is there and can react to it, as opposed
to other biomedical products that are inert. Bioactive
glass is very hard and stif, and it can replace some of the
inert glass fllers that are currently mixed with polymers
to make modern composite tooth fllings.
Almost all fllings eventually fail, and decay often
begins in the interface between a flling and a tooth.

NEVADA BECOMES FIRST STATE TO
ALLOW DENTAL HYGIENISTS TO USE
Most states already allow dentists to perform the procedure
In a new advisory policy statement, the Nevada State
Board of Dental Examiners has confrmed that Nevada
dentists and dental hygienists who possess the necessary skills and training are now permitted to administer botulinum toxin (Botox/Xeomin) and dermal fllers.
Nevada dental hygienists may only administer facial
injectables to patients under the direct supervision of
a Nevada licensed dentist who has the same skills and
training to administer facial injectables.
Nevada now joins the vast majority of states that allow
dentists to perform Botox and dermal fller procedures
for all uses in the oral and maxillofacial areas. It
also becomes the frst state to allow the use of facial
injectables by dental hygienists under direct dentist
supervision.—AAFE press release 17 December 2015
NOVOCOL HEALTHCARE, A SUBSIDIARY
OF SEPTODONT, ACQUIRES DEVICE
Novocol Healthcare expands injectable capabilities with a
strategic investment in device company Duoject
Novocol Healthcare Inc. (NHI), a subsidiary of Septodont
Inc. (Lancaster, Pennsylvania), has announced the acquisition of a majority stake in Duoject Medical Systems Inc.
(Bromont, Canada), a supplier of medical devices.
Todd Beechey, president of NHI, commented, “Te acquisition of Duoject enables NHI to ofer a more complete and diferentiated line of drug flling and delivery
solutions to our customers. Te acquisition of Duoject
transforms NHI’s injectable business from a sterile injectable flling company to a one-stop source for device
design and development, and pharmaceutical flling and
supply of unique injectable products.”—NHI press release 26
