Bad Teeth Research Articles

Founders' and Benefactors' lecture 2001. Preventing the preventable--the enigma of dental caries.

Vice-Chancellor, Deans, colleagues and visitors, it is a very great privilege to be invited to present the 50th Founders' and Benefactors' lecture. When I arrived in Newcastle as a lecturer in preventive dentistry in 1972, children aged 5 years living in Northumberland had an average of six bad teeth per child. Now it is much less and it is the purpose of today's lecture to describe the reasons for this success, but also, to indicate that the battle is far from won — the preventable is not yet prevented.

SURGERY: An Essential and Integral Part of the Healing Arts

In 1462, King Edward IV granted a charter of incorporation to free men of the … Barbers of our city of exercising the Mystery or the Art of 5 What did the king mean by And why use the words mystery and art? work of the barber-surgeon included drawing teeth and tending to wounds, bruises, and other ailments. These procedures long had been their province, as noted by King Edward. As the profession of medicine developed in the universities of Salerno, Naples, Pavia, Bologna, Padua, Montpellier, Paris, and later in the other cities of Europe, theory predominated over practice, and the hands-on healing of herbalists (largely women) and barbers (largely men) was disdained by the academic doctors. common traumas, especially those related to war, were handled by what we would now call physician's assistants or paramedical personnel, and the barber-surgeons and herbalists were not used by the university doctors; rather, they existed despite the power of the universities in the thirteenth and fourteenth centuries. Toward the end of the fourteenth century, guilds of surgeons became established in England and later in France. free men of the barbers of London were practicing their in a fashion similar to other surgical artisans for the previous 2000 years. Wherever people were, so also were injury and disease; bad teeth needed to be pulled; dislocated shoulders repositioned; broken bones splinted; abscesses drained; spearheads, arrowheads, and bullets extracted; tumors removed; lacerations repaired; and cataracts couched. Such nontheoretical and often hazardous tasks were not suited for those who did not speak the vernacular, or who were not prepared to take the risks of the routine complications associated with surgery. What, then, is surgery? Oxford English Dictionary (OED) defines it as: The art or practice of treating injuries, deformities, or other disorders by manual operation or instrumental appliances; surgical treatment. 9 Another definition of surgery could be The mechanical manipulation of the body, intended to benefit.

Good teeth, bad teeth and fear of the dentist

Studies of dental fear and oral disease suggest that conditioning processes are important in the acquisition of dental fear. At this time, however, definitive conclusions are premature as all research on the etiology of dental fear has been retrospective in design, with most confined to analogue or clinic samples. This study redressed these limitations by prospectively investigating the relationship between oral health (i.e. caries experience) at age 5 and 15 yr and the report of dental fear at age 18 in a large, unselected birth cohort. Caries experience at age 5 was not related to the development of dental fear in late adolescence. In contrast, caries experience at age 15 was significantly, and specifically, related to the report of dental fear at age 18. A ratio of caries severity at age 15, indicating the extent of multisurface involvement, was inversely related to dental fear at age 18. This intriguing finding suggests that relatively brief dental treatment occasioned by low levels of dental disease may result in the incubation of dental fear in some individuals and that longer episodes of treatment may facilitate fear habituation. Theoretical and practical implications of these findings are discussed.

磁性アタッチメントを応用した可撤性ブリッジ

Recently, superior magnetic attachment has been developed and put to clinical use. In particular, the effectiveness is anticipated for spical bad teeth because lateral force is hard to act on maintenance teeth as for the magnetic attachment. When a condition of the abutment tooth is compar atively good, we reduce unrest of the denture by giving a supporting system and can utilize it positively. And, there is not function fall by abration. As for application of magnetic attachment which is used for a healthy teeth and spical bad teeth, it is thought when effective. Magnetic attachment has functionality which became stable, esthetics excelled.In this study, we report it about a clinical case of removable bridge that magnetic attachment was applied as retainer.

Starvation and malnutrition of horses: recognition and treatment

Summary Starvation and partial starvation lead to loss of body weight and condition, which are general clinical signs seen also with bad teeth, bad feet, intestinal parasites, cancer, and several chronic diseases. More specific signs may accompany malnutrition, but often poor performance is the only indication. Thus both starvation and malnutrition require a careful differential diagnosis from the points of view of humane investigators and veterinarians. Abrupt refeeding usually results in the death of a severely starved horse in about three days. Thus, refeeding should be gentle, beginning with water and electrolytes, then enterals, slurries and, eventually, good quality forage and concentrates. Once the horse begins to thrive, it can be built up to a growth regimen. Not all nutritional abuse is due to nature or naivete. For example, the use of pre-taee jugs of intravenous nutrients occasionally causes fatal reactions. Also, the partial starvation of young horses confined in the dark to suppress manifestation of the wobbler trait has dubious merit, medically or ethically. Nutritional suffering may be countered therapeutically by recognition and treatment, and prophylactically by planning, education and regulation.

Acceptance Condition for Toothform- and Toothtrace Accuracy of Cylindrical Involute Gears and its Effect On Power Transmitting Characteristics : 1st Report, Acceptance of Gears with Bad Tooth Flank Form

To express the quality of the form of a gear tooth flank, the error surface defined as the difference between an ideal involute helicoid and an actual tooth flank of cylindricai involute gears expressed on the plane of action, is useful. Here, a method to illustrate the error surface for the form of a gear tooth flank from some tooth form- and tooth trace checking curves measured along some definite positions on a tooth flank is introduced. This method vas used in a simulation of power transmitting characteristics of cylindrical involute gears, and the problem of gear acceptance was discussed. It was found to be a problem to receive gears whose quality was actually out of tolerance and showed poor performances. The results of the state of tooth flank loading in the simulation suggested that this mistake occured due to the insufficiency of the test method of gear quality at acceptance.

Vestiges of the Past: The Role of the Grandmother in Contemporary Yucatec Literature

In the Popol Vuh, Xmukane', the old moon goddess, is a very imposing and extremely important figure in illo tempore.' She not only acts with other deities in the formation of the earth and its inhabitants, but she is the star actress when it comes to the creation of the corn men. On the other hand, she is also associated with death as evidenced when she cleverly kills Wucub Cac'ix. She also has a religious nature seen in her roles of a diviner, exemplified when she and Xpiyacoc divine with beans and corn in preparation for the creation of people, and a priestess, illustrated in the corn ritual and the rite of the con andnine beverages. In addition, Xmukane' was a doctor who treated Wucub Cac'ix's bad teeth and Hun Ajpu's broken arm. Finally, this goddess, who was a mother and a grandmother in the primordial era, had the responsibility of establishing rules of behavior for mankind to follow. To distinguish the roles of Xmukane', let's look briefly at the schemes repeated in her behavior. These schemes will be divided into the categories of religious, judiciary, political, and cultural. In her religious roles she acts together with other gods, provides the substances from which men of the second and third eras are made, and performs religious rites as a diviner, curer, and a priestess. Her position of a rain goddess is indicated when, with her water jar, she accompanies Jun Ajpu and Xbalanque several times to the river and cries when her sons and grandsons leave for Xibalba. Her judiciary roles are making family

Evaluation of the Ewesplint Method for Treating Broken Mouth in Sheep

The ewesplint method of treating broken mouth in sheep was evaluated on five farms in Caithness and Sutherland. The ewesplint is a commercially available technique for splinting together the eight incisor teeth of sheep using a stainless steel brace and acrylic resin. The technique of splinting proved to require considerable skill and practice and is likely to remain a contractor's operation rather than a farm skill. Three lowland Caithness farms which had park-type North Country Cheviot sheep co-operated in the trial. On these farms the sheeps’ teeth were short and broad (“good teeth“) and tooth loss was not a major problem. Two Sutherland farms, one of which was Achany, with hill Cheviots and Blackface X Cheviot sheep co-operated. On these farms incisors were long and rat-like (“bad teeth“) and tooth loss was a major problem. Results on the effectiveness of splinting are shown in Table 1. Most of the sheep on the Caithness farms were unsuitable for splinting because the teeth were too short to carry a splint. Of those that were splinted most lost their splints (62 %) after one year because of inadequate amounts of cement penetrating between the teeth. A more brittle dental cement was used in the Caithness farms which may also have contributed to the higher rate of splint loss.

Medical theories and professional development: The theory of focal sepsis and dentistry in early twentieth century Britain

This paper traces the history of the theory of focal infection—which related a number of general conditions to septic foci from which toxic products spread to different parts of the body—and its application to dental diseases in early 20th century Britain. Bad teeth were said to be one of the major sources of infection and a cause of many diseases. The paper focuses on the social and professional context in which the theory emerged and flourished. It shows that in spite of its lack of scientific foundation. The theory of focal sepsis was readily accepted by the dental profession and used to advance its claims for professional recognition. Thus the paper attempts to illustrate the point that the acceptance of a medical theory by health practitioners is as much determined by social and economic factors as by its therapeutic potential or its scientific validity.

THE APPEARANCE OF AMERICAN GIRLS, AS VIEWED BY MOREAU DE SAINT-MÉRY ABOUT 1795

The French jurist, Méderic Louis Élie Moreau de Saint-Méry (1750-1819), was driven into exile during the French Revolution by Robespierre's accession to power. From 1794 to 1798 Moreau lived in the United States. In the journal he kept during these years, he described American young girls as follows: American girls are pretty, and their eyes are alive with expression; but their complexions are wan, bad teeth spoil the appearance of their mouths, and there is also something disagreeable about the length of their legs. In general, however, they are of good height, are graceful, and, in enumerating their charms, one must not forget the shapeliness of their breasts. Philadelphia has thousands of beauties between fourteen and eighteen. To offer but a single proof: on the north side of Market Street, between Third and Fifth Street, on a single winter's day I saw four hundred young maidens promenading, each one of whom would surely have been followed in Paris, a seductive tribute that could be offered by perhaps no other city in the world. But these girls soon became pale, and an indisposition which is reckoned among the most unfavorable for the maintenance of the freshness of youth is very common among them. They have thin hair and bad teeth, and are given to nervous illnesses. The elements which embellish beauty, or rather which compose and order it, are not often bestowed by the graces. Finally, they are charming, adorable at fifteen, dried up at twenty-three, old at thirty-five, decrepit at forty or fifty.

Utilization of dental services in the adult Danish population 1975.

Lack of information on the dental behavior of adults in Denmark has become a major problem in the national planning of dental services. The purpose of this study was to establish the pattern of utilization of dental services among adult Danes (aged 15 and above). A three-stage cluster sampling design covering the total adult population of Denmark was used to draw a representative sample comprising 1,600 persons. Household interviews by trained interviewers were carried out. Of the adults interviewed, 58% reported yearly dental visits the last 5 years, 32% had not seen a dentist or only when in pain, and 10% went irregularly. Differences according to place of living, age, sex, occupation and school dental care were found. 63% of those who had seen a dentist reported bad teeth or were edentulous with or without dentures. 10% reported fear, 9% had good teeth and 5% reported economic difficulties. The most frequent treatments at the latest dental visit were cleaning and filling for the regular patients and extractions and dentures for the nonregular patients. A multiple classification analysis revealed that the number of teeth was the strongest predictor for dental services, with the following predictors in descending order: age, occupation, place of living, economy, sex and school dental care. These variables could explain 58% of the variation in utilization.

Dentistry as a profession

The question confronting many young individuals of today is what to choose fo r their life ’s work. Selecting a career that will utilize their own abilities and inclinations and also be of the greatest service to their coun­ try is usually not a simple problem. Indeed, the question is a weighty one, for upon the answer depends much of the happiness to be found in life and the happiness of others. These young people like to be where things are moving, where immense changes are in view, and w here they them selves can help bring about these improvements; and those who have im agination enough to see into the fu ture of their work and make progress toward it might well inves­ tigate and decide to make dentistry their profession. It is a work of ser­ vice to the people and to their coun­ try w hereby general health can be im proved, and thus greater happi­ ness can be brought to all. The most common diseases of mankind are those occurring in the teeth and their surrounding bone and soft tissues. Constant care is necessary if these diseases are to be prevented, controlled, and cured. The public is coming to understand what good dental care means to them , and their interest in it is in­ creasing. The dental profession must carry on this hum ane work of preven­ tion and healing so that people in all walks of life may be free from pain and loss of health because of bad teeth. It is a great task to undertake, but if ideals are kept high and above reproach, it can be done success­ fully and thus a great service can be done fo r our nation. One hears much these days about m aintenance of health and preven­ tion of disease. The schools are do­ ing much to educate the children and parents in the need for care of the teeth. The dentist plays a large part in this since many give freely and un­ selfishly of their tim e to lecture and bring about a better knowledge of w hat is needed to preserve teeth and health. M any people visit the dentist periodically and through his frequent exam inations and instructions on care of the teeth, he helps his patients to maintain their teeth and gingiva in sound condition. Pride is justly due the dentist for his service to children. Dental disease in children often continues through­ out life; therefore, when this is con­ trolled during childhood these future citizens have a better chance for the health and happiness they deserve. Through the correction of malaligned teeth, the dentist brings joy to many a youth who would otherwise go through life with an unsightly facial appearance. The physician and the dentist are mutually engaged in phases of health service to the people of their com ­ munities. It is necessary at times for these two professionals to work to­ gether for the proper treatm ent of patients. An invaluable service is giv­ en to patients by the dentist who is able to detect signs of cancer in the mouth or of diseases in other parts of the body. W hen these are in evi­ dence, he advises the patient to con­ sult a physician. Thus the dentist and the physician guard health on two fronts. Many public health departm ents have found that dentists are indis­ pensable to well-developed health plans. Dentists often serve on boards of public health, and many public health programs now provide for cer­ tain types of dental service for all groups of people. In this work den­ tists and physicians cooperate in planning and caring for the health problems of persons in the com m un­ ity, state, and nation. Many dentists engage in such ac­ tivities as teaching in dental schools, carrying on research in dentally re­ lated problems, and serving on state boards of dental exam iners. It may be noted that dentists have many things to do in caring fo r patients and car­ rying on their profession in such a way as to improve their service and maintain it on a level of which they can be proud. Dentistry as a profession requires men with special qualifications. The dentist must possess a fine charac­ ter, professional com petence, and integrity. Constructive ability, both imaginative and practical, is a nec­ essary requirem ent. In all of the den­

Good child, bad tooth: Management of the fear of tooth extraction in children

1. 1. The circumstances under which children arrive for dental extractions have been described, and some of the psychological responses of mothers and children have been outlined. 2. 2. Psychological reactions of regression, anxiety, and the concept of trauma are discussed in relation to dental procedures specifically and to personality development in general. 3. 3. Problems of separation of mother and child and of the child's inability to understand what is being done, as well as the tendency to misperceive treatment as punishment, are pointed out. 4. 4. Several cases are presented to show the responses of different normal children, especially some who became unresponsive and tended to withdraw under the experience of dental extraction. The evolution of the emotional aspects and the manner in which the reactions were handled are presented. 5. 5. The management of these problems in a clinically practical manner is discussed. We have stressed the importance of firm friendliness and honesty with the child, emphasizing clear communication and supportive behavior from the staff and parents. The need to avoid misinformation, haste, and angry criticism or judgmental attitudes is presented.

Cutting the Parallel Depth Bevel Gears on Gleason's Spiral Bevel Gear Generator : 2nd Report, Tooth Bearing Adjustment

It was stated in full on my 1st Report that if the parallel depth bevel gears were cut on Gleason's spiral bevel gear generator, the machine setting and cutter used were very simple and we could get easily the good spiral bevels with high accuracy. Then, the bad tooth bearings appear in very few cases caused by the unexpected factors. Those bad tooth bearings, however, may be easily corrected, for the numerical relations between the setting errors and the tooth bearing position are researched and stated in this paper. These relations can be applied to the tooth bearing control of assembling too. Then the tooth bearing adjustment of parallel depth bevel gears can be performed accurately and rapidly, outdoing the conventional trial method.

PRIMARY ACTINOMYCOSIS OF THE SKIN

History.— A white woman, 17 years of age and a resident of New York, who worked with jewelry, in October 1946 noticed a swelling on the line of the left lower jaw. She had at that time a carious molar in the left lower jaw and therefore went to a dentist. He ascribed the swelling on the face to a bad tooth, which he extracted. The wound healed normally, without any complications in the gum or cheek. The swelling on the face did not disappear after the extraction of the tooth, but became larger and began to soften. Two weeks after the extraction the patient went to a hospital in New York and was told that she had an abscess, which was incised and drained. After the drain was removed the lesion healed over, but on the fifth day after the incision the lesion again increased in size and again

A few important cultivated and wild leafy vegetables of South India.

That vegetables have played a very important part in the past and continue to do so in modern dietetics and that they are a very necessary menu in the every day meal of each and every person has been admitted on all hands. Among vegetables, leafy vegetables should be given the first and foremost place as they rank very high in the present day dietetics. In the first place they are the sources of calcium in abundance. Of all the metals calcium is the most important one as it is very essential for the build- ing up of bones and teeth. Deficiency of calcium in the diet has been responsible for a number of diseases. At the present day bad teeth are so common even among young people that one has to think well about the diet one should adopt to avoid this trouble. Very naturally therefore greens such as amaranth, cabbage, fenugreek, spinach etc. are advocated to one and all especially to young children and expectant and nursing mothers. In the second place leafy vegetables contain the pigment carotene which is said to fulfil the physiological function of Vitamin A in the body. The importance of vitamins is so well recognised that it need not be dealt with in this short note.
