DIET ANALYSIS OF ONE HUNDRED AND ONE PERIODONTOCLASIA CASES* By BENJAM IN TISHLER, D.M.D., Boston, Mass. H E follow in g report is an analysis of diet lists of a group of periodon toclasia cases taken from m y prac tice, with a few from the clinic of the Harvard D ental School. T h e purpose o f the analysis was to ascertain, with the limited material at hand, any facts which might be of interest. Each patient was requested to record carefully the amount o f all food and drink consumed for an entire week, whether at or between meals, and such extra items as candy, cakes and sodas consumed between these

periods. A s each list was presented, doubtful items were checked up in the presence o f the patient and any errors corrected. A s a consequence, many lists were eliminated as unsatisfactory, and the final analysis was made from 101, gathered over a period o f tw o years, rep resenting food eaten at all seasons, so that the entire list comprised more than 2,100 meals. T h e patients’ ages varied from 18 to 63 years, and the lesions pres ent from an incipient to a markedly ad vanced type of periodontoclasia, with or w ithout visible pus discharge. It should be understood that while the w ork has been closely carried out as regards the analysis, the amounts o f the

A c curate amounts could only have been obtained by weighing all solids and meas uring all liquids before eating or drink ing and the same process repeated with such as may have remained unconsumed, the difference having been the net amount
actually ingested. This, o f course, could not have been done under the circum stances.

Bureau of Hom e Economics, Depart ment of Agriculture, W ashington, D . C., who employed a standard in grams for the various required nutrients in whole, half and quarter portions, both for a man and for a woman. From these, an analysis was prepared for each diet list using the terms, adequate, probably adequate, low and very low as the re sults indicated. T h e recorded nutrients were protein,, protein efficient, calcium, iron, vitamins A, B and C, roughage
and liquids. It was originally intended to include iodin, phosphorus and calories, but as the question o f the influence of iodin is still uncertain, it was omitted. M iss H unt also decided that the data on phosphorus were too insignificant to be included. Calories, on the other hand, are affected by the amount of sugar and fats in the food and also by the amount of butter, oil or syrups used. Because these foods are so concentrated and are used in varying amounts, it seemed use-

balanced diet; in other words, ninetyseven individuals were found to have eaten unwisely in one or more o f the recorded nutrients. Nine showed a defi ciency in every item (a 100 per cent un balanced d ie t). Seven were deficient in from five to eight items, with the bal ance, necessary to complete the nine, recorded as probably adequate only (n ot an adequate amount in the entire num ber of nutrients). T h e balance o f the diet lists varied from one to nine ade quate items, and the latter group, which

women gave the information that they were accustomed to restrict the amount and kind of food eaten to avoid an ac cumulation o f surplus flesh, a condition which, as far as could be determined, did not affect the men, whose diet analyses, by the way, disclosed an equally marked deficiency in many cases. In computing the averages of the various elements, it was found that three items of the nine already referred to were conspicuously lo w : calcium, vitamin A and liquids (m ostly w a ter). O f the 101 recorded cases, about 96 per cent showed an un

represented those w ho ate a balanced diet, numbered but four (o f the original 101 exam ined). In order that a definite idea o f the diets as a whole may be obtained, tw o groups of opposite age extremes have been chosen and recorded. O ne repre sents lists submitted by younger patients ( nineteen in num ber) whose ages ranged from 18 to 30 years. These showed a general nutrient deficiency, with but one exception, and this diet list was adequate in all items. T h ree lists were deficient in all nutrients, one in all but tw o and an

other in all but four, all of which were recorded as adequate. T h e clinical symptoms of both groups varied from an incipient to a markedly advanced type, with the advanced predominating. T h e other group of twenty, chosen from the opposite age extreme (4 9 to 6 3 ) dis closed a similar general diet deficiency. In fact, the lists of both groups could have been reversed without appreciably affecting the result. T h e balance o f the remainder of the lists, which completed the 101 chosen, i. e., those between 30 and 49 years, showed the same general deficiency and symptoms as the tw o groups just referred to, which would lead one to believe that, as far as the experiment is concerned, diet is not a conclusive etiologic factor in periodonto clasia when individuals are considered, but when the 101 cases are examined collectively, one cannot overlook the general lack of the calcium and vitamin A intake, and also that of water, which is so important in fecal elimination and bears a direct relationship to intestinal toxemia, long recognized as an etiologic factor in periodontoclasia. O f the tw o groups, just reported, it was hoped that the younger would offer the more promising material for consid eration because the periodontal disinte gration had its inception at a more recent date than in the case o f the older groups, but, as has been observed, it offers no conclusive results on which a positive
statement can be made. It would seem, therefore, that more definite data could be obtained by an examination of the diets of still younger patients, of high school age or younger, if found neces sary. T h e advantage of this is obvious, because it is apparent that a knowledge of the character o f the diet eaten during the formative period of life, when early periodontal lesions have their inception, is most important. It cannot be disputed that many persons make radical changes in their diet as soon as they are permit ted to choose it, as in adult life, thus making the task of relating diet to perio dontoclasia a difficult one. It is safe to assume that this could be determined with more certainty during childhood or youth, for the closer that the etiology (deficient diet) and the possible effect (periodontoclasia) can be brought to gether, the more definite should be the findings which w ill prove their exact re lationship. It is hoped that further w ork o f this kind w ill be undertaken, because those familiar with dietary problems who have been consulted are of the opinion that such experiments offer promising results. A suggestion is hereby offered to those w ho may desire to undertake w ork of this kind that a dietitian be enlisted to supervise the accumulation of the diet lists, because of her expert knowledge in such matters.
