BLOOD AND VULCANITE
anthropologist of investigating the remains of " The
the future, when the inhabitants of
Britain in the first half of the twentieth century, will undoubtedly comment on the large number of young adult skeletons with no teeth."1 No statistics of toothlessness are available, but doctors and dentists in all but the most well-to-do practices will support this prophecy. Who is to blame for these wholesale extractions ? Too often, particularly in the industrial areas, the condition of the teeth of working-class people in the early twenties is such that extraction is the only possible treatment. Apart from the debatable influence of diet and environment, these teeth are being lost because they are inadequately attended to at school and completely neglected in the immediate post-school years. The staffing of the school dental service is insufficient-and in some places grossly insufficient-to carry out the necessary conservative work on permanent teeth ; and, more important, a large proportion of parents, often as many as 60 per cent. in schools where the teachers’ persuasive powers are poor, refuse to have fillings done. On leaving school, at an age when dental caries is particularly prevalent, the working-class adolescent is left for several years without provision for dental treatment, and later he only qualifies for benefit if his approved society has a disposable surplus and he is able to pay half the cost. Many extractions are unavoidable under the present system, but many others are unnecessary and unjustifiable. On another page Mr. L. G. ROBINSON lays some of the blame for these at the door of the medical practitioner. With no real knowledge of dentistry, he says, doctors send their patients to the dentist with a demand for extractions, and unless he is a hospital consultant the dentist can hardly refuse to comply with such orders, backed as they invariably are by the patients themselves. Very many doctors overestimate the importance of dental sepsis as a cause of general disease : faced with a condition such as chronic rheumatism, which may have a septic origin, they are too ready to convict obvious dental sepsis as the cause, at any rate until its removal has proved them wrong. Secondly, they are apt to underestimate the seriousness of extractions : the removal of many teeth, especially if done at one sitting, is far from being a trivial operation, and may activate a smouldering infection and be the stepping-stone from poor health to invalidism; or the toothlessness of subsequent months may precipitate a gastric or duodenal ulcer. Further, many doctors have an exaggerated 1.

faith in dental prosthesis ; no artificial teeth are as efficient as natural ones, and though most people can be made reasonably comfortable, many with unduly sensitive gums or abnormal alveolar arches can never masticate properly with a denture. There can be no doubt, however, that ruthless extraction is encouraged by the less scrupulous members of the dental profession. The removal of all teeth and the provision of complete dentures is the easiest and quickest way of making money where fees are low. Many of the unqualified dentists to whom the Dentists Act of 1921 gave a legal standing were never trained in conservative methods, and their livelihood depends on the teeth they condemn. The approved societies these blood-and-vulcanite encourage practitioners by their low scale of fees, their objection to partial dentures and fillings (often admittedly with reason), and their rules that allow only one ansesthetic fee. Doctor, dentist, and approved society thus all play their part in providing data for the future anthropologist, but fundamentally the attitude of the public themselves is to blame for the loss of countless teeth that might be saved. Even where almost gratuitous treatment is available many parents and adult patients will not spare the extra time and trouble for fillings, but prefer to wait until extraction is inevitable. A large section of the community, moreover, have come to regard it as almost natural to have their teeth out at an early age. Until this attitude changes it will be of little use for the school dental service to be reinforced, for treatment to be provided for adolescents, or for the approved societies to extend their benefits. Much can be done to educate the public in schools and welfare centres, but even more by the medical practitioner ; he must ensure that in this his powerful influence is exerted on the right side.
CHEMOTHERAPY IN CEREBROSPINAL FEVER THOSE whose daily work is facilitated by expert
nursing and lavish equipment may well feel
inclined
to raise their hats to the three officers in the Sudan Medical Service whose experiences in the treatment of cerebrospinal fever are described
elsewhere in this issue. The’word " primitive " seems inadequate to describe the conditions under which their work had to be done, and the expression "field conditions" takes on a new and more literal meaning when the operation of lumbar puncture has to be performed on patients lying on the ground. The only attentions the sick received, apart from the specific treatment with which these papers deal, were those provided by relatives. The treatment itself was primitive in the sense that tablets of sulphonamide compounds are unsuitable for preparing solutions for injection : some of these fluids were necessarily not solutions at all, but suspensions, which even tended to block the needle with which they were injected. In spite of these grave disadvantages, the treatment appears to have been an almost miraculous success. Patients walked home only a few days after it was begun, and local " ’ medicine men ’ forsook their

Dr. SOMERS used M. & B. 693 only; it was altogether removed by obtaining positive Drs. BRYANT and FAIRMAN used this for most of cultures in ox-serum broth directly from rheumatic their cases, and sulphanilamide for the much material. This was achieved with the arthritic smaller number which their limited stock of this exudate from one case and with an excised drug enabled them to treat ; and for what the erythema-nodosum nodule from another, and the fact is worth the recovery-rate on both drugs was cultures thus made were found to have the same 95 per cent.
