CONCERN FOR PATIENTS:
Dental School Explores Ways of Reducing 'Torture'
*1
11
More comfort for the patient
and superior materials for fillings
and dentures are the objectives of
research in the Dental Materials
Testing Laboratories of the Uni-
versity School of Dentistry, said
Pror. Floyd A. Peyton, head of the
dental materials department.
Investigators are constantly at
work cutting extracted human
teeth into sections, exposing them
to tests and then attempting to
develop new materials of superior
quality for replacing tissue lost
due to decay or accidents.
Engineering and mechanical
principles are applied in this type
of research because, as Prof. Pey-
ton puts it, "'We are dealing with
the body's food crushing machin-
ery, the teeth."
In addition to comfort, it is the
goal of these researchers to find
materials that can be inserted,
more quickly and conveniently in-
to the patient's mouth.
Special Projects
Dental Materials Testing Labor-
atory is currently conducting eight
special research projects, six of
which are being sponsored by the
Army, Navy, Air Force, and Public
Health Service.
Coun't Basle
Concert Set
Prof. Peyton compares the ac-
tion of teeth when chewing to that
of a giant press. Because of the
similarity, artificial tissue replace-
ment naterials are tested in a
small compression and tension
machine.
He estimates that the bite of a
husky person "may exert up to 200
pounds, of pressure." A less rugged
person may have a normal bite
presure of 50 pounds and the
average Is "probably between 50
and 75 pounds."
I.ocation of the tooth in the
mouth is important in determin-
ing tooth pressure. Prof. Peyton
adds that the pressure capacity
depend§ on the dimensions and
area of the tooth.
Withstands Pressure
A normal human tooth may be
able to withstand pressure of from
40,000 to 60,000 pounds per square
inch without breaking.
Dental materials researchers are
working with materials:( used in
restorative dentistry such as gold
alloys, silver alloys, plastics, porce-
lains, cements, and impression ma-
terials.
They also work with denture
materials such as acrylic, porce-
lain, and chrome alloys; and with
orthodontic materials such as sil-
ver and gold.
Researchers are interested in
changes in dimension of these
materials when introduced into
the patient's mouth. They are
concerned with the snugness of
the fitting and the dimension re-
lationships between restorative
materials and live teeth.
Hot coffee or cold water can be
painful when a filling or other re-
storative material is not compat-
ible with the reactions of natural
tooth tissue.
They are also interested in the
hardness and strength of these
materials. Will they last and will
they react in the same way as'
normal tissue?
Use Water Spray
One of the valuable results of
recent research in Prof. Peyton's
department was the determination
that using a water spray to cool
the dental drill will reduce the
patient's pain.
For experimental purposes and
instead of subjecting patients to
"torture," they took an extracted
tooth, mounted it, made a cut
with the standard drill, and meas-
ured the heat generated.
Researchers found that the
water spray reduced the frictional
heat to a comfortable level for
the patient.
'Filling' Teeth
Sections of human teeth are be-
ing "filled," then exposed to heat
and cold, in order to learn the best
and most compatible "substances
for use in restoring teeth.
Hook shaped wires and clasps
which anchor partial dentures
come in for their share of engi-
neering tests, too.
On a machine which flexes short
lengths of the wire used for clasps
in partial dentures, they are ex-
posed to millions of "bends" or
flexures within a few hours.
Flexures duplicate the flexing
of clasps in the mouth with each
bite.
One of Prof. Peyton's students
found that an average person
makes about 5,000,000 "chews"
per year.
Gold-Old 'Standby'
Prof. Peyton stated that of all:
the filling materials available to-
day, the old stand-by, gold alloy,
has not lost any of its importance
over the years.
"Some persons prefer other sub-
stances for aesthetic reasons," he
says, "but it is a mighty fine
restorative material from practi-
cally all aspects."
He says that much work is being,
done on improving plastics for
restorative purposes, as some of
the early plastics were unsuitable
colorwise.

PROF. DAVIS:
Underprivileged -Pupils
Lack A ttention in Class
Prof. Allison Davis of the Uni-
versity of Chicago stressed the
importance of training socially
underprivileged children in a lec-
ture yesterday.
His talk, "Reaching the Masses
of Pupils," highlighted the last
general session of the 28th annual
Summer Education Conference
under the auspices of the School
of Education. The conference be-
gan Tuesday.
Prof. Davis stated that lower
Administration
Institute Meets
Two sessions of the Third An-
nual Institute on College Admin-
istration were held yesterday in
the Michigan Union.
General theme was "Student
Personnel Administration." A spe-
cial luncheon featured an address
by Prof. Algo D. Henderson, of
the School of Education.
Two more sessions at 9 a.m. and
2 p.m. today at the Michigan
Union will cover the theme "De-
fining and Implementing Pur-
poses."
class children and their teachers
are separated by a forest of im-
penetrable cultural barriers which
make real communication between
the two extremely difficult.
To break down this barrier, he
said, it is necessary that the
teacher understand the child's
language, discover the pupil's at-
titude toward the teacher, and
overcome his own biases.
Turning to' the problems of the
middle class child, Prof. Davis
said, "Middle class culture places
great emphasis on the distant re-
wards of a career or profession."
This puts children under pressure
to obtain the arbitrary goals set
up for them or face the disgrace
of failure..
He pointed out a behavior differ-
ence between the classes. The low-
er class child can fight when he is
angry and does not have to
"accept the false peace" which
the parents of middle class child-
ren impose.
In conclusion, Prof. Davis vigor-
ously criticized today's curriculum
as barrier to understanding on the
basis that they force children
"simply to miemorize.",
