Dr. Keyes was requested by the Mother Superior of St. Vincent's orphan asylum, Boston, in November, 1910, to establish a dental infirmary for the care of the children's teeth. Two children were installed as assistants, a great aid in inspiring confidence in the children needing treatment. Monthly lectures were given to the upper grade children, in the schoolroom, and they were required to write compositions after lectures, as aid to the hygienic teachings. Morning and evening tooth drill was instituted, prize given to child with cleanest mouth at end of month, separate brushes and tooth powder placed in cabinet containing 250 compartments. These were inspected monthly. Every three months the children were lined up and inspected by the dentist, a separate mouth stick being used for each child--just taking two hours to inspect the children in this manner. The following statistical table shows the "relation of oral prophylaxis to infectious diseases: "In the year 1905-6 the home was in quarantine for over three months-an epidemic of scarlet fever of over 75 cases. "A comparison . . . will show that in six months after work was begun . . . the ratio of infectious diseases was reduced 59 per cent; and that in the subsequent year this ratio was reduced to approximately 2 per cent. . . . "Is this absolute elimination of disease for a period of twelve months a coincidence? It may be so.... But certainly no such condition ever existed in St. Vincent's asylum prior to the installation of a dental infirmary." MICHIGAN. BUNTING, Russell W.

A report of examination made in 1906, 1907, for the compilation of various dental statistics in connection with anthropological measurements made upon the same children by Dr. Robert Bean. Examinations were made of 1,525 children, from 5 to 17 years of age. Two kinds of records were taken, a dental chart and an anthropological chart. "From the data thus collected we endeavored to ascertain whether or not there were any correlations between the child's physical or mental development and the time of eruption of the teeth or the amount of dental caries present; also whether the caries and the teeth eruption were influenced by the type of the individual.” The distribution in the mouth of the 2,068 carious teeth noted (negroes omitted) is shown, there being in the lower jaw 1,167 cases of caries as against 901 in the upper jaw; "in the lower right first molar, 10 per cent of the number erupted at 6 years of age were found to be carious. The percentages steadily increase... until in the sixteenth year there are in the upper jaw from 35 to 40 per cent of carious first molars ... more than one in every three examined, and in the lower jaw the same tooth at that age has 70 per cent affected, or two out of every three examined. . . . "The upper incisors show a steady increase in their percentage of caries from the eleventh to the sixteenth year, and at the latter age the centrals have the very high percentage of 35, while the laterals show about half that number. The lower incisors exhibit but little caries at any of the ages examined. "In the bicuspids there appears to be decided advance in the number decayed between the fifteenth and the sixteenth year, and the upper bicuspids at all ages exhibit about twice as many cases of caries as are found in the same teeth in the lower jaw. "The canine is seldom decayed in either upper or lower jaw, but the second molar at the age of 16 has between 20 and 30 per cent of the total number affected by caries." A special study of the 60 negro children of Ann Arbor, and the 112 negro children and 61 white children of Detroit, was made. In the whites, 9.2 per cent of the teeth erupted were decayed; in the negroes, 6.2 per cent. Stature weight in relation to Other tables are: Stature weight in relation to eruption: Boys, girls. caries: Boys, girls. Brain weight in relation to eruption: Boys, girls. caries: Boys, girls. Teeth of girls erupt earlier than boys. In both sexes, individuals large for their age have more teeth present than the undersized or normal. The increase in the caries of the large children over that of the small is so marked, that it is probable there is some cause other than the presence of more teeth. A great many children with large heads, who were said to be very advanced mentally, were found upon examination, often with mouths full of caries and irregularities. There were 142 cases of malocclusion; 18 cases of very badly developed teeth, and between 30 and 40 cases showing pits or grooves in the incisors and bicuspids. NEW YORK. BARLOW, Peter C.

Letter sent to superintendents of the 34 important general and special dispensaries, asked four questions as follows: "1. Does your dispensary have a dental department? "2. If so, how many dental surgeons are in attendance, and for how many hours a week and at what time are they engaged in giving their services? "3. Do the patients have to pay for the material for filling teeth, etc., or is it given gratuitously? "4. If there is no dental service attached to your dispensary, would you be willing to establish one and arrange special hours for school children so that the time for visiting the dispensary may not conflict with school hours?" The 33 answers appear in full in the report, of which the following is a summary: To the report comprising sixteen dispensaries independent or attached to hospitals, we must add that there exist three dental clinics maintained by the Children's aid society, kept fully employed with the care of the teeth of the children attending the society's schools. There is also one free dental clinic, being the health department's institution. Rochester. Board of education.

"With 97 per cent of the public school children in need of care and treatment, and with the worst oral conditions showing an improvement of from 37 to 50 per cent in working efficiency, would it not be conservative to consider that with all . . . the mouths in good first class condition that there might be an average increase of at least 10 per cent in working efficiency for all the children in the schools?... "The records of 1909 and 1910 show a registration of practically 65,000 pupils in the elementary schools and . . . we would show an expenditure of $170,625 a year to educate children handicapped by faulty oral conditions; but, in making the above estimate, our committees placed their percentage at a figure which they are positive is less than half of what actual tests would show. And, if we double the above amount we find that we are spending $341,250 per year to overcome the handicap of faulty oral conditions."

Report form. "In the public school, our educational system proposes, first, to make a cursory examination of each child, sending into the home a record of that examination, and bringing the parent or guardian a knowledge of a faulty oral condition. . . ... "The second step. . . is to put into the schools, when the examiner has finished and the parents and pupils are prepared for them, a system of lectures which explains the purpose, use, care and and treatment of the mouth. "Third... is the establishment of the dental clinic. . . to make possible the securing of data which will show the value of the healthy oral conditions as related to the working efficiency of the child from the economic side of the question. . . from the school reports of the pupils, preceding and following treatment." In the Cleveland, Ohio, Marion school, an experimental class was formed, of 40 boys and girls selected as having the worst oral conditions of all the pupils. Their school records for the six months preceding the test were taken, two psychological tests made before we began our work; the children furnished with toothbrush and powder and a dental nurse placed over them. Test meals given, the teeth all treated and filled, and a $5 gold piece offered as prize to each child faithfully carrying through the conditions of the test. Two psychological tests will be made during the time of test; and two will be made during the six months following treatment, with the school records, "and from these records it is expected to secure evidence which will show the value of dental service in dollars and cents."

G. Ebersole, M. D. In June 1909, 10 dentists and 10 nurses or attendants, began the inspection of the mouth conditions of the 846 children of the Marion school, Cleveland; out of the 846, but 3 were found to have teeth in perfect condition. Out of the entire number of dental charts, 40 were selected, as representing the worst mouth conditions, for the experiment. (1) They were to have their teeth put into perfect condition. (2) They were to brush their teeth carefully three times a day. (3) They were to masticate their food properly, not using liquid with solid food. (4) They were to attend any and every meeting of the class called and to conform to regulations laid down. In mental efficiency the children made gain of 99.8 per cent shown by psychological tests, one given in May, one in June, one in August and one in September, 1910; last two given on the 4th and 10th of May 1911. Longest time spent on one phase of the work during a test, was less than three minutes. The children who needed the improvement most were the ones who made the greatest gains.

"The conclusion is strongly suggested that the desirability of establishing dental clinics in the public schools, for free inspection and treatment, should present itself to the taxpayer as a plain business proposition; ... the paying of proper dividends on the capital invested in the schools. . . . "We started out with a class of retardates and repeaters. During the experimental year only one of the 27 pupils failed of promotion. According to the best estimates there are 6,000,000 retardates (pupils over age for their grades) in the public schools of the United States. . About one-sixth are repeaters (pupils who must spend more than one year in one grade). It costs the country annually $27,000,000 to educate every sixth child over again; i. e., a second, third, or fourth time in the same grade. (Ayres) "During the experimental year not a single truancy card was made out to these 27 pupils.... On the psychological side, the class showed an improvement. which amounted on the average to about 50 per cent. That a large part of this increased efficiency was directly due to the mouth orthogenics is attested by the parallel pedagogical improvement made by the pupils... An efficiency improvement of 10 per cent. . . would amount to one school year in ten . . . and in the aggregate would save millions of dollars annually to the taxpayer." ...

Of a total of 1,036 deciduous and permanent teeth, 436 were defective; in 25 children the number of defective teeth exceeded the intact teeth; 8 children used toothbrush daily, and 4, occasionally. In the 86 children, ages 8 to 11 years, of a total of 1,781 teeth, 627 were carious; about 1 pupil out of every 7 used the toothbrush daily. In the 110 children, ages 11 to 15 years, of a total of 2,616 teeth, 636 were defective; toothbrush used occasionally by the majority of the children. In 25 of them, from 2 to 4 first permanent molars were decayed beyond help; 15 had good first permanent molars, nearly all filled, as well as the full number of teeth for their respective ages. Those children whose deciduous teeth had received attention, showed healthy mouths, and "as far as could be learned, they possessed keen mental development. ... "In the children examined a number gave evidence of toxic infections. They were pale, listless, apathetic, gave a history of headache, and were unable to cope with their studies.
