Células madre a partir de dientes de leche

marzo 26, 2010 Deja un comentario
Un estudio de reciente data apunta a que los dientes de leche pueden ser fuente de obtención de células madre, mucho  más fácil incluso que del tejido embrionario. En este reporte de Salud.com tenemos detalles más ampliados del tema y más abajo, vemos como en Venezuela existe ya una alternativa

_____________

Los dientes de leche que los niños esconden bajo sus almohadas con la esperanza de que el ratón les traiga un regalo, podrían algún ­día utilizarse para extraer células madre empleadas en tratamientos que salven vidas, dijeron el domingo cientí­ficos australianos.
Los dientes de los infantes han sido identificados como una valiosa fuente de células madre, más fáciles de obtener que las controvertidas células embrionarias, dijeron investigadores del Instituto Hanson en el Royal Hospital Adelaide.
Las células madre en tejidos de adultos pueden ser complicadas de obtener o se presentan en cantidades muy pequeñas, expresó el director del Instituto Hanson, Howard Morris.
La pulpa de los dientes es una fuente bastante buena de células madre y éstas son muy sensibles a su obtención. Pierdes una gran cantidad de ellas cuando eres un niño pequeño.
Las células madre tienen la capacidad de transformarse en cualquier célula o tejido. Los investigadores creen que tienen el potencial de revolucionar la medicina.
La investigación con dientes de niños acaba de empezar, pero los cientí­ficos del hospital Adelaide esperan que las células puedan algún dí­a ser utilizadas para tratar enfermedades como el Parkinson o reparar órganos cruciales como el corazón o el riñón y evitar la necesidad de transplantes.
Células madre en Venezuela
Con la ayuda de BioEDEN almacenar las células madre de los dientes es muy simple y fácil de hacer.
BioEDEN es una compañía internacional de operación bio-científica. Es la primera empresa en recolectar, aislar y almacenar criogénicamente las células vivas del diente de leche.
Los dientes de leche aparecen generalmente a los seis meses de edad y se caen entre los seis y doce años. Con la ayuda de BioEDEN las células de estos dientes pueden ser preservadas para un futuro uso médico actuando como un seguro biológico para su hijo.

Un robot que simula ser un paciente dental

marzo 26, 2010 Deja un comentario
Para que los estudiantes de odontología tengan una experiencia más cercana a la realidad, ingenieros de varias universidades japonesas desarrollaron un proyecto que fue presentado hoy. Se trata de un humanoide que hará las veces de paciente en las prácticas de odontología. La noticia está en La Tercera y disponemos de una completa galería de imágenes acá

 _______________

Presentan robot que simula ser un paciente dental

El humanoide tiene como objetivo principal que los aspirantes a dentistas puedan enfrentar todo lo que implica un trabajo dental.

Aparentar ser un paciente en una consulta de dentista es la misión de Hanako, un robot humanoide que fue presentado hoy y desarrollado por ingenieros de las universidades japonesas Waseda, Kogakuin y Showa.
El humanoide tiene como objetivo principal que los aspirantes a dentistas puedan enfrentar todo lo que implica un trabajo dental, pero en un paciente falso, por lo que pueden cometer errores sin provocar daños.
Hanako está equipado con un conjunto de dientes de plástico duro y tiene una realista cavidad bucal, que incluso representa a la perfección el flujo de saliva y hemorragias, si es el caso.
Los sensores que posee el robot permiten que tenga capacidad de expresión de manera que los alumnos pueden además de mejorar la habilidad de tratamiento, aprender a mantener una conversación con los pacientes para relajarlos.

Turismo dental se impone como tendencia – (En inglés)

marzo 26, 2010 Deja un comentario
El creciente auge de los implantes dentales como sustitutos de las piezas perdidas ha impulsado a los pacientes (más que todo de países desarrollados) a buscar las mejores opciones para llevarse a cabo estos procedimientos fuera de sus fronteras. Inglaterra, Irlanda, Francia y Estados Unidos, en medio de sus economías retraídas se han visto forzados a buscar un cuidado dental que puedan pagar en países como México, India, Hungría y Polonia. Este trabajo nos llega desde World Dental.

________________

The past half decade has seen an incredible boom in dental tourism. Flocks of people from developed states such as England, Ireland, France and the United States, are striving to find an affordable yet high quality form of having dental treatment. The current economic crisis along with the increasing cost of dental care in most of the Western European countries and North America force 350 thousand people each month to travel to Mexico, India, Hungary, Thailand and Poland, in order to find an alternative solution to save on the cost of their dental therapy. Is it any wonder then that dentistry is the only sector that managed to maintain a continuous development during the recession?
Dental implant treatments are among the most popular dental services for which medical tourists are willing to travel thousands of miles. In their home countries they have to face the lack of proper NHS dentists, extremely long waiting lists and the huge cost of going private. It may not be much of a surprise that many are beginning to discover that certain countries offer exactly the same services of the same standards to which they are accustomed, at a much lower price. As dental tourism is becoming a more and more widespread phenomenon, implantology clinics of the destination countries are providing their clients with state-of-the-art technology, specially trained dentists and nurses as well as high safety and health standards.
Having dental implant treatment far away from home
Dental implants are screw-shaped prosthetic devices made of titanium or zirconia, designed to support restorations that replace missing teeth. They serve as tooth roots and unlike dentures and bridges, implants are not attached to neighbouring teeth and thus feel like real teeth. The procedure is typically carried out in stages and uncomfortable though that may seem, there is a common practice to arrange the process of the therapy. A comprehensive treatment plan is developed during an initial consultation, at times even before departure. Depending on the number of implants to be applied and the extent of complementary treatments such as sinus lifting or teeth whitening, two or three separate five-day visits are required within a period of three to nine months.
Reducing dental bills by up to 70 per cent
As the hourly wages and rents in the destinations of dental travel tend to be far below those of developed countries, there are huge differences in the price of dental procedures. By way of illustration, while patients may have to pay as much as £2,500 for each implant in Britain, they are available from £500 in Hungary. Factoring in all the travel and accommodation expenses that could mean a saving of up to a quite impressive 75 per cent. What is more, a visit to the dentist may be part of a holiday or a family trip, with the opportunity to explore a foreign culture.
The European Commission plans to enact legislation to allow patients from EU countries to receive medical treatment in any other member states and reclaim at most as much of the money spent on health care as the same procedure would cost in their own country. Since dental implants are mainly considered to be reconstructive dentistry treatments and dental tourism is based on finding affordable dental prices, there should be no trouble having the full amount reimbursed.

Dental implants in Hungary
Let us introduce you to the dental tourism of Hungary and its capital city Budapest, which some say is steadily becoming the dental capital of the world. Dental care in Hungary is of outstanding quality thanks to its world-renowned medical education. As a response to the increasing demand, more and more dentists specialise in implantology. A rising number of clinics are available, offering exceptional dental care with the most advanced equipment and technology. Yet the prices are really competitive due to the low incomes and cheap labour of this area. Following Mexico, Hungary is the second most popular destination of dental tourists from around the globe and the top destination for European dental travelers, with 42 per cent of them choosing this country to have dental work in. Most of the patients from all around the world are considering dental implants in Budapest (Hungary) which is the most commonly performed procedure at Hungarian dental clinics.
Dental tourism here had started 10-15 years before it did in any other nations, and first spread along the western border when Austrians then Germans and Italians discovered the benefits of having their dental therapy a few miles away, in Hungary. Later as patients from other European countries became aware of the cost-effective Hungarian dental care, the centre of dentistry gradually moved to Budapest. In order to maintain its leading position, the country applies strict dental regulations and provides special ’dental packages’ with the arrangement of the whole stay from departure to arriving home, including plane tickets, hotel reservation, appointments with the doctor, the treatment itself, even leisure activities and 24-hour emergency assistance. Tourists come mainly from the United Kingdom and also Ireland, France, Scandinavian countries, Austria and Italy.

Are dental implants abroad safe?
There are several pieces of information and misinformation about the cleanliness of clinics and the safety of treatments of developing countries. As a matter of fact, figures show that they are neither more dangerous nor less professional than Western European clinics. Furthermore, Hungary and Poland are members of the European Union and they have set up standards in accordance with EU health care policy. Additionally, most of the dental works carry a guarantee so that if any complications arise, the clinics, of course, treat all the disorders, usually without charging any additional fee; and some of them even reimburse travel costs.

Más riesgos de la gingivitis durante el embarazo (En inglés)

marzo 26, 2010 Deja un comentario
En OralNet ya habíamos hablado de los riesgos de padecer gingivitis durante el embarazo. En este nuevo post, de un artículo de DentalWorld lleva esos riesgos más allá y expone -aunque con cierto recelo- que la vida del feto podría incluso estar en riesgo, puesto que las bacterias que causan la gingivitis podrían diseminarse a través del torrente sanguíneo y llegar al bebé. Si bien no todos los gérmenes contribuyen directamente con la muerte del feto, sí pueden ayudar a crear complicaciones. El artículo está en inglés

________

Women with gum disease are almost three times more likely to give birth prematurely than those with healthy gums, according to more than a decade of research. But scientists are still uncertain how significant a risk dental bacteria is to healthy pregnancies – or how to save foetuses from potentially deadly exposure.

Because of hormonal changes, women are prone to develop gum disease – generally treatable – during pregnancy. “The old wives’ tale about losing a tooth for each baby – we have shown how with periodontal [gum] disease and other underlying conditions [mother’s health], you may lose more than just the tooth, but also the baby,” Yiping Han, a periodontics researcher at US-based Case Western Reserve University, told IRIN.
Gum bleeding can carry bacteria to the placenta – which it can penetrate and kill the foetus if the mother’s immune system does not fight back, according to recent researchHan conducted of a woman who had severe gingivitis during her pregnancy. “The mother delivered her full-term baby dead at 39 weeks,” Han told IRIN. The researcher found the same bacteria in the mother’s dental plaque as was in the baby’s infected lungs and stomach.

Even if dental germs do not result in death, they can contribute to delivery complications and long-term health problems for the child, said Steven Offenbacher, director of Center for Oral and Systemic Diseases at the University of North Carolina. “Forty percent of foetuses are exposed to dental bacteria… These babies are three times more likely to be born early, to spend more time in neonatal units and to have long-term disability,” he told IRIN.

Countries with high rates of premature births also tend to have a high prevalence of gum disease, Han told IRIN. “Oral health care is typically seen as a luxury in poor countries, when in fact, it is the gateway to overall health. The closed mouth hides the often overlooked threat of oral bacteria on a pregnancy.”

Each year an estimated 13 million babies – mostly in sub-Saharan Africa – are born before 37 weeks of pregnancy; one million of these die, according to the World Health Organization (WHO). More than three million full-term stillbirths occur annually worldwide.

A 2007 analysis by dental epidemiologists from Toulouse, France, of 17 studies dating to 1996 on periodontal disease and preterm births – tracking more than 7,000 pregnant women – found a “likely association” between gum disease and preterm births, but concluded that more research is needed.
Offenbacher said preterm deliveries and stillbirths have many causes and it is difficult to isolate one risk from another.

Periodontal Treatment
But there is mounting research that successful periodontal treatment can reduce premature births, according to the University of Pennsylvania, whichrecently presented its study of 872 pregnant women with and without the disease.
Twenty-three percent of those with gum disease delivered before 35 weeks versus 7 percent without the condition. Those who received treatment had a medically “significant” lower incidence of preterm births, lead researcher, Marjorie Jeffcoat, told IRIN. “We believe the results would be applicable to babies worldwide and would be happy to work with any doctor who would like to study this effect in their country.”

Sierra Leone
In Sierra Leone, which has one of the world’s highest infant mortality rates – 159 for every 1,000 live births based on the most recent government data from 2006 – the Health Ministry has not considered periodontal disease a major risk in pregnancy. S.A.S. Kargbo , the ministry’s reproductive health specialist, said the association between periodontal disease and pregnancy complications is a “hypothesis” and he does not know of any cases.
But without epidemiological studies or enough human resources, it is hard to prove the link between gum disease and pregnancy complications, researcher Han told IRIN. “And without that data in hand, it is hard to convince countries to devote more resources to periodontal care in an effort to reduce their infant mortality rate.”
Sierra Leone had five dentists – about one for every one million residents – in 2004, according to the most recently available government records.
“If a country is determined to bring down its infant mortality rate, periodontal disease is a well-documented risk that can derail a healthy pregnancy and deserves further examination,” Han said.
