Management of odonto-stomatological emergencies during the COVID-19 alarm state in dental clinics in the Autonomous Community of Madrid (CAM), Spain: An observational study.

BACKGROUND: Odontology practice has been severely compromised by the pandemic caused by COVID-19 and Spain is one of the countries with higher incidence. Our aim with this study is to find out the number of cases and type of odonto-stomatological emergencies (OSE) treated in four dental clinics of the Madrid capital area and region (CAM) in the period covered between March 17th and 4th of May. MATERIAL AND METHODS: We search the cases in the demographic/epidemiological databases of the CAM regional government and the Illustrious Official College of Dentists and Stomatologists of the First Region (Madrid). RESULTS: We found that the most prevalent pathology was acute apical periodontitis whereas odontogenic abscess showed the lowest frequency. Prosthetic-orthodontic OSE represented 14% of cases. CONCLUSIONS: In this period of time, the most prevalent pathology acute apical periodontitis, odontogenic abscess reported the lowest frequency and prosthetic-orthodontic treatments were the third in number of cases. Most of OSE were resolved, without referring the patient to a hospital emergency department.

Oral anatomy in the sixteenth century: Juan Valverde de Amusco.

In 1554 Juan Valverde de Amusco, a Spanish anatomist, wrote the History of the composition of the human body, a complete anatomical treatise that took as its model the Vesalius school of thought (La fábrica of Vesalius). Considered one of the most complete anatomical treatises of the Renaissance and one of the most widely read books of the sixteenth century, it was translated into four languages in its day. The first chapter, devoted to bones, provides a meticulously detailed analysis of the bones of the facial structures and of the teeth, their supporting structures, vascularisation and innervation. Juan Valverde de Amusco even describes techniques for reducing mandibular luxations. Even with the imprecise observations typical of the time the treatise must be considered an exceptional document.

Europe's oldest jaw: evidence of oral pathology.

Atapuerca, in the north of Spain, is the archaeological site where the oldest hominid remains within Europe have been found. In 2008 a jaw fragment, corresponding to the symphyseal area, was discovered in the area called the 'Elephant's pit'. Its age has been estimated at 1.2 million years and it is considered to be the oldest human fossil found in Europe and is from the lower Pleistocene. This work analyses the dental and skeletal damage to the specimen, detected in a macroscopic study of possible horizontal and vertical bone loss at the level of support of the remaining teeth. The limited presence of dental scale, the pattern of destruction and the decreased bone density due to increased marrow spaces suggest the presence of possible periodontal disease.

The discovery of surgical anesthesia: discrepancies regarding its authorship.

The suppression of pain during surgical interventions has been a major achievement for humankind. Chronologically, in 1842, William E. Clarke, a chemist in Rochester (NY), provided Elijah Pope with ether for the purposes of tooth extraction. In 1844, in Boston, G.Q. Colton and the dentist Horace Wells used nitrous oxide as an anesthetic for tooth extraction. On the 16th of October, 1846, the American dentist William T.G. Morton became a pioneer within the medical community with respect to anesthesia by inhalation when he used ether as an anesthetic at the Massachusetts General Hospital. In 1847, the Scot James Young Simpson began to use chloroform as an anesthetic for obstetrics in Edinburgh. These events gave rise to several disputes among their users (who are not very well-known today), who strove to claim that they had been the discoverers of surgical anesthesia, with a view to obtaining a series of patents and state sinecures. This article attempts to clarify certain discrepancies about the authorship of surgical anesthesia. The evidence suggests that surgical anesthesia first began to be applied in the field of dentistry.
