Establecen que una variaci�n gen�tica es indicativa de riesgo de c�ncer oral

Universidad Nacional de C�rdoba - Facultad de Odontolog�a

A trav�s de un estudio in�dito en Argentina, investigadores identificaron que cierto tipo de mutaci�n en el gen TP53 est� relacionado con un mayor riesgo de desarrollar c�ncer oral. Esto se debe a que esa alteraci�n gen�tica es menos eficiente en la supresi�n de la transformaci�n celular, m�s lenta para inducir la apoptosis (muerte celular programada), y menos eficiente en la uni�n e inactivaci�n de una prote�na supresora de tumores (inhibe la proliferaci�n de c�lulas). El descubrimiento permite avanzar en la construcci�n de modelos predictivos para facilitar el diagn�stico de esta patolog�a, a partir del cruce de los signos y s�ntomas cl�nicos con las caracter�sticas gen�ticas del paciente.

Universidad Nacional de Rosario - Facultad de Odontolog�a

Un equipo de estudiantes y docentes de la Universidad Nacional de Rosario realiz� un trabajo de promoci�n de la salud bucal en distintas comunidades del norte del pa�s, una actividad que la C�tedra Odontolog�a Social IV desarrolla desde 1998. Los investigadores resaltaron la importancia de �darles la informaci�n para que puedan prevenir las enfermedades; de lo contrario no hacemos una odontolog�a a conciencia porque s�lo trabajamos sobre la patolog�a�.

Innovative Biomaterial to Regenerate Bone through the Combination of Proteins

Universidad Nacional de Tucum�n - Facultad de Odontolog�a

Scientists from Tucum�n designed a malleable membrane which stimulates cells and produces neobone formation in a few weeks. The researchers� idea is that, through the use of national origin products, the biomaterial can become accessible for patients. The work is in a pre-clinical stage and it was successfully tested in animals.

Use of Piercings in University Youths

Universidad Nacional de Rosario - Facultad de Odontolog�a

The School of Odontology carried out an investigation on the use of piercings among the students of the first years of the career considering the age, most frequent locations, adverse reactions and lesions, as well as the motives which led them to use them and take them out.

Detection and Treatment of Facial Asymmetries

Universidad Nacional de Cuyo - Facultad de Odontolog�a

The specialist Adriana Poletto investigates the relation of facial asymmetries with joint dysfunctions and clarifies that Odontology has to treat them in time, during childhood in order to avoid permanent and irreversible damages. Through the study carried out by the researcher it is seek to elaborate integral diagnostic protocols and establish the adequate treatment to deal with the pathologies in an interdisciplinary way.

Research to see if there are Links between the action of Mate Water and Mouth Cancer

Universidad Nacional del Nordeste - Facultad de Odontolog�a

Mate is a well rooted Argentinean and Uruguayan custom. The way to prepare it is so diverse as there are regions in Argentina, but everywhere the common factor is the high temperature of the water. This detail led two Faculties of Odontology in Argentina and Uruguay to investigate if the thermal action of mate is a risk factor which predisposes to mouth cancer.
