NEWEST THINGS ~ DENTISTRY.
ELECTRICITY PLAYS AN IMPORTANT PART
IN MANIPULATION AND IN DEAD


ENING PAIN.
There has been no branch Of science within re-
years that has progressed than dentistry.
The master dentist OF to-day different operator
In every way from his brother even himself. OF
q decade ago The advances made In the science
OF the teeth have been In curious direction how
eyer Not very much more is known regarding
dental diseases than IN the past. but the instru-
mcnts used hove been so improved and simplihed
10y modern mechanism that there has come about
almost a revolution In the profession Operations
that formerly long and painful requiring
brute force and a strong arm are now performed
almost in twnkling. the agony Is much de-
creased. and science gives promise Of day when
teeth shall be filled and extracted with hardly any
pain at all.
Electricity is the agent that bids fair to advance
the art Of dentistry to higher point than 1t has
ever before reached The idea Of an electric motor
take the place. Of foot and hand power in driving
the delicate little instruments used in doctorng
the teeth is by means new; in fact. the problem
has been studied and worked for dozen
years and more. but IT Is only lately that electricity
has been satisfactorily harnesscd to the work and
fun and complete outfit Of electrical dentists
tools devised and constructed so that any dentist
OF fair intelligence can lrarn TO readily use them
Not alon" in the Of electricity. though. has the
art Of dentistry advanced Every instrument used
has been brought to a high state of perfection and
the mechanical improvements every hand
doing FOR the physical comfort Of the patients.
Electricity H. 10y means in wide use yet. though
many OF the foremost dentists Of the country are
adopting IT and installing motors in their Of
