Higiene y cuidado dental en recetarios hispanos de los siglos XIV-XVI / Hygiene and dental care in Hispanic recipe books from the 14th-16th centuries

Numerosos recetarios de época bajomedieval y moderna contienen información sobre tratamientos destinados al cuidado del cuerpo, en especial del cabello, la piel o la dentadura. Se trata de textos misceláneos, donde los contenidos de medicina se mezclan con los de dietética, salud y belleza, motivo por el que en ocasiones han sido llamados “libros de mujeres”, debido a su vinculación con costumbres del grupo femenino. Tales textos incluyen indicaciones para la preparación de compuestos destinados a la limpieza de dientes y a combatir el mal aliento, recetas que incorporan materias antisépticas y de efecto bactericida disueltas en agua, o usadas en forma sólida para frotar directamente las encías, como dentífricos con que cepillar los dientes y la lengua. También compuestos destinados a encarnar las encías y a prevenir sus enfermedades, o a calzar los dientes débiles y faltos de raíz. Y detallan la forma de aplicación de dichos polvos y letuarios, que suele efectuarse frotando los dientes o mediante enjuague bucal. El artículo estudia estas recetas y analiza tanto las propiedades de las materias que las integran como los procedimientos seguidos para su aplicación. (AU)

Historical perspectives on advertising and the meme that personal oral hygiene prevents dental caries.

The consensus of a leading scientific panel in 1930 was that oral hygiene products could not prevent dental caries. Their view was that dental caries prevention required the proper mineralisation of teeth and that vitamin D could achieve this goal. Over a hundred subsequent controlled trials, conducted over seven decades, largely confirmed that this scientific panel had made the right decisions. They had, in 1930, when it comes to dental caries, correctly endorsed vitamin D products as dental caries prophylactics and oral hygiene products as cosmetics. And yet, despite this consistent scientific evidence for close to a century, an opposing conventional wisdom emerged which thrives to this day: oral hygiene habits (without fluoride) protect the teeth from dental caries, and vitamin D plays no role in dental caries prevention. This historical analysis explores whether persistent advertising can deeply engrain memes on dental caries prevention which conflict with controlled trial results. The question is raised whether professional organisations, with a dependence on advertising revenues, can become complicit in amplifying advertised health claims which are inconsistent with the principles of evidence-based medicine.

"Karius and Baktus": A Critical Appraisal of Enger's Seminal Storybook.

Karius and Baktus, first published in 1949, is one of the most influential storybooks with dental caries as main theme and it remains in wide use for domestic health education. This study aimed at assessing oral health related contents of the historic storybook in the light of the current body of cariologic evidence. Two investigators independently identified phrases in the storybook with cariologically relevant content. Dental health related contents were systematically evaluated with respect to the current body of cariologic evidence. Karius and Baktus highlights important etiopathogenetic and preventive aspects such as sugars consumption and tooth brushing with toothpaste. Its behavior management techniques and narrative health didactics concerning dental care for children are, however, outmoded. The cariologic core statements in Karius and Baktus have remained valid whereas certain narrative features may have some drawbacks when employing the historic storybook for educational purposes for young children.

Evidence of toothpick groove formation in Neandertal anterior and posterior teeth.

OBJECTIVES: During the microscopic examination of the Neandertal dentitions from El Sidrón (Spain) and Hortus (France), we found unusual fine parallel microstriations on the mesial and distal sides of all tooth types, near the cervix. As its appearance was similar to toothpick grooves described in other Homo species, it could correspond to early stages on its formation. To test this hypothesis we developed an experimental replication of a groove using grass stalks. MATERIALS AND METHODS: Comparisons between 204 isolated Neandertal teeth and the two experimental dental specimens corroborate that the marks correspond to initial stages of toothpick groove formation, and we propose a five-grade recording scale that summarized the groove formation process. RESULTS: Using this new recording procedure, we found that Hortus individuals have higher incidence of this trait (eight individuals out of nine) than the El Sidrón individuals (nine out of 11). Toothpick grooves from El Sidrón show the earliest stages of development, whereas the grooves found on Hortus Neandertals were well-developed. Toothpick grooves were also found in 21 incisors and canines. CONCLUSIONS: These differences could be due to the more advanced occlusal dental wear in Hortus individuals, maybe age-related and with a more meat-based diet maybe favoring the inclusion of food debris and thus probing as the cleaning methodology. Our results allow the identification and characterization of incipient toothpick grooves on the human fossil record and contribute to increase our knowledge on Neandertals behavioral and oral care habits.

Dental worm disease.

During human evolution, the period in which groups of humans stopped harvesting fruits and seeds growing wild and introduced the cultivation of cereals as well as the domestication of animals represents a very important event. This circumstance had a considerable impact on human pathocenosis, increasing the risk of infectious diseases of animal origin. The aim of this review was to summarise the archaeological and palaeo-pathological evidence in the literature concerning this topic. Starting from early prehistory (about 1.5 million years ago) up to the historical period, several authors have described the changes in human habits and the consequent changes in food supply, leading to the transition from a protein- to a carbohydrate-rich diet across a broad interval of time. This led to additional problems for human health. The increased accumulation of carbohydrate debris in the odonto-stomatological apparatus, without the appropriate use of hygiene in the oral cavity, increased the risk of infectious disease involving the mouth. Therefore, since the Neolithic period there has been a higher risk of tooth caries, abscesses, deep infection of the teeth roots, reaching also the mandibular and maxillary bone. Several hypotheses have been proposed by the distinct civilizations, which have alternated in the different ages, to explain the cause of these human health problems, including the idea that a "dental worm" could be involved in this process, such as in the Sumerian period. We describe and discuss further modifications of this theory, developed in Egypt, Assyria, Babylon, China, Greece, in Etruscan cities and in Rome in ancient times as well as in the Middle Ages, and the evolution of scientific thought on this topic in the past 300 years. In addition, the results of some palaeo-pathological studies, which were performed on human remains, such as the maxillary bone and teeth, mainly in different geographical areas in Italy, are examined and reported.

[The historical materials of stomatology in the All Things, Prescriptions of Fifty-two Diseases and Yinshu].

All Things, Prescriptions of Fifty-two Diseases and Yinshu were three bamboo and silk medical manuscripts which form-time was no later than the late Warring States period. From the visible bamboo and silk, the ancient Chinese knew the relationships between some drugs and the volume of saliva and used compound drugs to treat dental caries. Some oral and maxillofacial diseases, such as inflammation and pain of oromaxillo-facial region, temporomandibular dislocation and the methods of treatment were descriped in these books. Mouth-rinsing and tooth-picking were the more often used methods for maintaining oral hygiene. Kouchi(clicking the tooth)was also used for prevention and/or treatment of caries. Most of these knowledge were the first documents in ancient China.

Dental caries and chemical analyses in reconstruction of diet, health and hygienic behaviour in the Middle Euphrates valley (Syria).

OBJECTIVES: The aim of this study was to use two methods, biological and chemical, to examine changes in diet and health in individuals from the Middle Euphrates valley (Syria). We determined the frequency distribution of dental caries. Chemical analyses were concerned with the presence of elements such as strontium, barium, calcium and stable carbon isotopes ((13)C/(14)C). We chose three consecutive periods: Late Roman (2nd-4th century AD), Islamic (600-1200 AD) and Modern Islamic (1850-1950 AD). MATERIALS AND METHODS: We analysed the dental remains of 145 individuals, with a total of 2530 teeth. We used visual research (magnifying glass/sharp dental probe) and radiography. The frequencies of caries were calculated on the basis of the proportional correction factor of Erdal and Duyar. We chose 39 permanent second molars for chemical analyses. RESULTS: The frequency of carious lesions was similar in all three periods (6-8%). In the Modern Islamic and Islamic periods, occlusal surfaces were infected with caries most often, while the cemento-enamel junction (CEJ) and approximal surfaces were affected to a lesser degree. However, in the Late Roman period, the CEJ and approximal surfaces showed caries most frequently, in contrast to occlusal surfaces, which seldom showed signs of caries. Chemical analyses showed lower Sr/Ca ratios and Observed Ratio index values for the Modern Islamic and higher values for the Islamic and Late Roman periods. Mean stable isotope (δ(13)C) analyses demonstrated that the Modern Islamic period was strongly divergent from the other periods. DISCUSSION: These data suggest a similar socio-economic status during the Late Roman and Islamic periods. The diet of the population living in the Late Roman and Islamic periods contained a larger number of products containing strontium than calcium. In the modern population these proportions have been reversed.

Oral hygiene in the Shari'ah: a thousand-year-old conversation between Islam's schools of legal thought.

By examining Islam's jurisprudential literature about oral hygiene, this paper traces the scholarly discussions of jurists in the years after the Prophet Muhammad's passing until the present day. While previous inquiries into this subject have focused on the novelty of the Prophet's use of a tooth-stick, the focus of this effort is not to serve as a material history of tools. Rather, this paper focuses on the reasons for the religious mandate in Islam to maintain optimal oral hygiene. It does so by triangulating the varioustheories of oral hygiene expounded by jurists over time and geography.

The history and global market of oral home-care products.

This literature review reports the history and the current market of oral home-care products. It provides information extending from the products used by our ancestors to those currently available, as well as on the changes in the supply and consumption of these products. Although the scientific knowledge about oral diseases has improved greatly in recent years, our ancestors had already been concerned with cleaning their teeth. A variety of rudimentary products and devices were used since before recorded history, like chewing sticks, tree twigs, bird feathers, animal bones, tooth powder and home-made mouth rinses. Today, due to technological improvements of the cosmetic industry and market competition, home-use oral care products available in the marketplace offer a great variety of options. An increase in the consumption of oral care products has been observed in the last decades. Estimates show that Latin America observed a 12% increase in hygiene and beauty products sales between 2002 and 2003, whereas the observed global rate was approximately 2%. A significant increase in the per capita consumption of toothpaste, toothbrush, mouthrinse and dental floss has been estimated from 1992 to 2002, respectively at rates of 38.3%, 138.3%, 618.8% and 177.2%. Pertaining to this increased supply and consumption of oral care products, some related questions remain unanswered, like the occurrence of changes in disease behavior due to the use of new compounds, their actual efficacy and correct indications, and the extent of the benefits to oral health derived from consuming more products.

The era of whiter teeth: advertising in American dentistry 1910-1950.

It has often been argued that the public image of dentists has been tainted by association with fear and pain into an image of evil 'psychodontists' and that there is an apparent lack of 'role models' in popular film, television, art and literature concerned with dentistry. This paper argues that we get a different picture when looking at different media. Advertisements introduce into a public domain, positive images of dentistry which crucially differ from the images found in other popular media. This paper traces the public image of dentistry in early 20th-century America, as seen through dentifrice advertisements, and suggests three important reasons for studying advertisements: First, advertisements provide a supplement to studies of popular images of dentistry carried out so far. Second, advertisements have played an important part in advancing oral hygiene as a public concern. And third, advertisements provide the historian of dentistry with a unique opportunity for analyzing the complex and interwoven relationship of popular and professional discourses, since ads have acted as catalysts for professional discussions and self-reflection among dentists.

[The dental aspects of public health in Hungary. Review article]. / Magyarország népegészségügyi helyzetének fogorvosi vonatkozásai. Osszefoglaló közlemény.

Despite great improvements in the oral health status of the population, public health and dental public health continue to be a major problem in society. A number of epidemiologic studies revealed the importance of the social, behavioral and environmental factors contributing to inequalities in the maintenance and restoration of oral health. Dental public health is the science and art of preventing oral diseases, promoting oral health and improving the quality of life through the organized efforts of the public. The aim of the authors was to provide an overview about the development and the functions of the Hungarian public health and dental public health system, its associations with international dental public health organizations and about the present dental public health status of the Hungarian population. According to WHO pathfinder studies, the Hungarian population has a usual cariologic and periodontal status in Europe, but a number of WHO statistical analyses reveal the sad situation regarding the high frequency of oral malignancies in our country. The social support system is given, the tasks are in front of us, and Hungary intends to follow the oral health strategies of the WHO for 2020 in order to improve the dental public health status of the nation, but it is necessary to declare that not only behavioral but also political decisions are necessary for that goal.

[Dental aspects of general symptoms in the 18th century]. / Altalános kórképek fogászati vonatkozásai a XVIII. században.

In the 18th century, numerous diseases with symptoms of oral cavity were cured by chirurgien-dentist, barber-surgeons, or tooth drawer. The so called "dentitio difficilis" was blamed for the high children mortality, therefore gum cut or use of leeches was advised as a treatment. Both acute and chronic type of gum inflammation was called scurvy. It seems that the mechanical removal of plaque was enough to cure the scurvy as it was written in advertisements from that time. Syphilis was present in the everyday life throughout centuries, and assumed to cause different stigmas in the oral cavity. Today we consider theses stigmas as the toxic signs of mercury treatment.
