Cau~es for Loss of Permanent Teeth
The permanent tooth ~xtraction
incident in 2000 patients (10-70 years) who presented themselves at the School of Dentistry the first part of the academic year, 1940-41 was studied. 459 patients actually experienced extraction of 1242 teeth. An attempt was madr

to differentiate those teeth lost because of periodontoclasia. Some of the percentages overlapped be- cause some teeth were removed for more than one reason. The carious tooth classification includ- ed those with large cavities or cases with only carious root frag- ments remaining (743 teeth (60 per cent) ) . Of 34 per cent ra- diographed prior to extraction 13 revealed definite pulpal involve- ment, while 12 showed apical in- volvement. A total of 422 teeth
( 34 per cent) were extracted be- cause of periodontoclasia: 96 per cent with unquestionable loss of investing tissue; 2 per cent an ad- ditional generalized periodontitis.
At time of extraction it was planned to replace 13 per cent with full dentures and 8 per cent with partial dentures. Near- ly 1 per cent of the teeth were removed to correct malocclusion, 1 per cent for esthetic purposes, 3 per cent because of impaction, about 1 per cent under advice from the physician for general health reasons. A miscellaneous classification included 2 teeth ex- tracted because they were super- numerary, 7 root tips left from previous extractions performed elsewhere. Gingival recession in combination with erosion caused a loss of 5 teeth; abrasion plus excessive erosion the loss of ap- proximately 24 teeth. Arrange- ment of extraction groups accord- ing to decade showed caries uni- formly the outstanding cause for tooth loss. The average age at which greatest number of teeth were removed because of period- ontoclasia was 45 years while for caries it was 32.5 years. 30 per cent of all teeth removed were diagnosed radiographically. - George W.

Anatomy (Microscopic) of the Sal- ivary Glands
of
the Rat.The salivary glands of the rat are similar in many respects to those of man. Macroscopic fea- tures have been reported previous- ly (J. D. Res., 18 :457, 1939). The alveolus is the secretory unit and, in the principal glands, many are congregated into lobules which comprise lobes. The excretory system is made up of branching ducts, . smaller ones starting as in- tercalated ducts lined with flat spindle-shaped epithelial cells. In large ducts epith_elium is psuedo- stratified. Stenson's duct empties the parotid, Wharton's the sub- maxillary and an independent duct the major sublingual. The minol' su blingual has several independent openings, ducts of Rivinus. The alveoli of the parotid consist of typical polyhedral albuminous

Pedodontic Department 1941 Graduate Assigned
Active To Naval Academy
During the past year the Pedo- dontic Department has been busy from both the teaching and serv- ice aspect. At the start of the school year the new system, as- signing the students s~ many hours per week in the department, was instituted and has been very suc- cessful. This method affords rou- tine appointments for each stu- dent so that the required amount
o~ clinical work may be accom- plished each semester.
A study of the records shows that 2,375 separate operations for 1,473 appointments were p~r
formed during the past year. Con- sidering the small number o~ stu- dents in attendance in the senior class this amount of work afford- ed ample clinical experience for each student. This clinical train- ing in Pedodontics included han- dling the juvenile patient accord·- ing to his reaction to dental treat- ment, examination, recording, op- erative methods and procedures for the child, and such special services as fractures, space reten- tion, and prosthetic appliances for children.
The training in the children's clinic is well supplemented by a weekly lecture on the theory and fundamental principles of Pedo- dontics. This includes a thorough consideration and discussion of the following aspects of the subject:
child psychology and manage- ment; examination and diagnosis;
operative methods for deciduous and young permanent teeth; fill- ing materials and their use; treat- ment of vital and non-vital decid- uous teeth; preventive measures for children; and space retention.
In both the clinic and lecture room particular emphasis is placed on the preventive aspects of Pedo- dontics and considerable time is used familiarizing the student with technics as well as the valut.!
of such services to the child pa- tient.
In addition to instructing the undergraduate, the Pedodontic De- partment has been busily engaged in a program of instruction for the practitioner throughout the state. This has been accomplished by the University supplying lec- tures and clinicians for component societies and by sponsoring, as well as supplying, part of the teaching staff for regional re- fresher courses given by the State Board of Health to component dental societies throughout the state.
It will be of interest to recent grad uates to learn that Dr. Les- te1· Mosson, who received his den- tal degree from this school in 1941, is now assigned to duty at the U.S. Na val Academy at An- napolis. Dr. Mosson has the rank of Lieutenant, Junior Grade, in the regular navy. He was suc- cessful in his attempt to pass the navy entrance examination short- ly after his graduation.
We have been informed that Dr.
Vernon Anderson, who also has the rank of Lieutenant, Junior Grade, in the regular navy had been assigned to the naval acad-
emy 'until recently. He is now
assigned to the U.S.S. Wasp, an aircraft carrier, which at present is somewhere at sea. Dr. Ander- son was a member of the faculty during the year 1940-41.
Dental Faculty Con- ducts Seminar Meetings
Four to be Held During School Year.
At the first of a series of four faculty Seminars planned for thP current school year a paper wac read by Dr. Virgil D. Cheyne, Associate Professor of Histology and Pathology, on "Dental Caries."
Another was read by Mr. Ralpb Phillips, Instructor in Dental Ma- terials, on "Wrought Gold Alloys."
Formal discussion by the entire faculty was held on the contents of the papers which were reports on recent investigations made by the respective departments of the two essayists.
On January 19, the second Sem- inar was held. At this meeting Dr. Henry B. Morrow, Professor of Periodontia, presented a paper on "Differential Diagnosis of Gin- givitis as Related to Local and Systemic Conditions." This pres- entation was discussed by Dr. R.
A. Solomon, Associate Professor of Medicine, and Dr. Lyle Weed, As- sistant Professor of Bacteriology.
Dr. T. D. Speidel, Professor of Orthodontia, read a paper entitled
"A Basis for Noting Dento-Fa- cial Relationships." The entire faculty discussed this paper in- formally.
The meeting was concluded by a discussion led by Dean Craw- ford of the proposed consolidated curriculum of the school of den··
tistry resulting from the national emergency.
Case History:
j which appeared to contain bone.mall perforations of both the labial and lingual plates of bone were found. Unfortunately it was necessary to remove the lower left lateral incisor and cuspid.
Fibro-Osteoma
Clinical History
S. M., male, age 40 years, and in apparently good health, came to the dental:;-clinic in February, 1941. At that time he had a complete dental examination, in- cluding full mouth x-rays. Some minor operative work was per- formed and he was dismissed. He returned to the clinic in N ovem- ber, 1941.
Oral Examination
At the time of his first visit, the x-ray of the lower left cus- pid region revealed a circular, rarefied area located between the roots of lateral incisor and cus- pid, near but not involving the apices of the teeth. It was some- what feathery in. outline. A thor- ough examination failed to reveal any pathological condition of the teeth or their supporting struc- tures which could have been re- sponsible for the lesion. The his- tory was equally negative. All of the lower anterior teeth gave a vital response with the electrical pulp tester.
Fig. 1 Radiograph of a fibro- osteoma.
With the exception of this area of rarefaction, the mouth was in an excellent state of health. A">
there were no subjective symp- toms from the lesion, it was de- cided to suspend treatment for a period of six to eight months.
When the patient returned in No- vember, 1941, another x-ray of the lower left cuspid region showed the rarefied area to be slightly larger. and more sharply outlined. The center of the area now showed a granular radiopac- ity as though it were undergoing calcification (Fig. I). It was de- cided to operate for fear of a p'()ssible malignancy.
The surgery was performed and a granular mass enucleated
Pat.ho logy
The microscopic picture present- ed is that of an altered or trans- formed bone manow. Normal marrow is transformed into fi- brous tissue and new bone trabe- culae have formed, seemingly causing a complete transforma- tion of the bone. Dense accumu- lations of osteoblasts were found in scattered locations. Although these were abnormal in number, it was not believed that the tis- sue gave any evidence of malig- nancy. A diagnosis of fibro-os- teoma was made on the basis of the clinical history and the micro- scopic and radiographic findings.
Discussion
Radiographically, this type of growth appears to be circum- scribed and radioluscent in its earlier stages, becoming more ra- diopaque as bone is deposited.
Subjective symptoms are rarely, if ever, present and the growth is considered benign by most au- thors. The etiology is obscure al- though it has been thought that trauma may in some way be an exciting factor. Total excision is desirable except in later stages where removal of the growth would result in considerable loss of structure and disfigurement.
First Alumni War
Casualty Reported
Word has been received by Mrs.
Annie L: McCurdy of Fort Wayne, Indiana, that her son, Captain Howard A. McCurdy, who re- ceived his Doctor of Dental Sur- gery degree in the class of 1929, was reported killed in action on January 16 while serving with General Douglas MacArthur's forces in the Philippines. Mrs.
McCurdy sa1d that she was "proud to be the mother of a man who gave his life in defense of our dear America."
Captain Mccurdy, according to the best available information, was the the first alumnus of the school of dentistry to be reported killed in acti'On by the War De- partment. He began active serv- ice with the army in March, 1940, as a dentist with the rank of Captain in the army air force at Fort Lewis, Washington. He was transferred to the Philippines the following June.

Abstract s
(Continued from Page 2)
As a supplement to the investi- gation of the general physical condition of all beginning students in Indiana University, a complete dental examination was again made this year. Approximately 1200 male and 800 female fresh- men were examined by Dr. Doyle
E. Pierce, Dr. William F. Koss, of the School of Dentistry, and their assistants.
_e.search was conducted on major cells with zymogen granules be- This marks the second year tl at

For a long time, bubbles on ::astings have been a source of najor concern to the dentist. Va1·i-

!Ulty. However, none were entire- '.y satisfactory until the advent )f various wetting agents a shorr
.ime ago. This material is u:~
~cubtedly the solution, and the
"heory upon which it works should be understood by all who use it.
Water has a very high surface
· ension and when placed on wax, Trill not spread out on the sur- face but will tend to form gfobules and drops. We may consider in-
·:estment in the same respect as
"-ater for it behaves identically.
' herefore. if investment is paint- --<1 on a pattern without first ap- 1lying a wetting agent, the su;.·- :ace tension will tend to make it frrm globules, prevent even dis- lribution, and thus facilitate the
·-.. apping of air bubbles as it is
"'.Uplied. However, if some mate- rial is spread on the wax which
·ill reduce the surface tension of i:he water, the investment will flow out easily to all parts of +he pattern. The water in the 'nvestment tends to form a film over the wax rather than sepa-
-rate drops. Bubbles are usually
e1iminated and the process of in- vesting is made much easier.
Liquid soap is a satisfactory material as most wetting agents are of similar composition. Many operators have been under the im- nression that this same result may be obtained by cleaning the ryattern with soap and then al- lowing it to dry before investing.
However, this does no good in re-
