Merry Christmas 2012

"And so I'm offering this simple phrase
To kids from one to ninety two
Although it's been said many times, many ways
Merry Christmas to you"
(Christmas Song Lyrics)

Thank you very much for supporting our project this year!

Pulp Pathosis in Mayas' Teeth

The Mayas were a Mesoamerican civilization with a highly developed culture that inhabited the Yucatan Peninsula, which comprises the Mexican states of Yucatán, Campeche, and Quintana Roo; the northern part of the nation of Belize; and Guatemala's northern. The nation's history began about 2500 B.C., but their culture flourished from 300 A.D. to 900 A.D. Based on archaeological findings, at least 60 percent of the total population was engaged in some form of tooth modification.

In Maya’s dental practice, teeth were filed into points, ground into rectangles or cavities were prepared to permit the insertion of round pieces of stone in over a hundred different patterns. This relatively complex procedure was done using a hard tube that was spun between the hands or in a rope drill, with slurry of powdered quartz in water as an abrasive, to cut a cavity through the tooth enamel to allow placement of an inlay. These inlays were made of various minerals and were ground to fit the cavity so precisely and the adhesive was so effective that many burials found by archaeologists today still have them firmly in place.

Roots Summit 2012

From 18th to 20th of October of 2012, Roots Summit ( will take place in Foz do Iguaçu, Brazil. This is a very special event because it materializes the international virtual collaboration of the Roots forum in a country. There will be more than 20 presentations and 20 workshops related to the endodontic field in 3 days. Do not miss the chance to see and hear noteworthy clinicians and researchers from all around the world. I may say that this will be one of the most important endodontic meetings that ever happen in South America. More than an opportunity to share knowledge and skills, this will be an opportunity to celebrate life! In this way, I would kindly invite you to meet me on Friday, from 17h20 to 18h10, at room Atlantico. It will be an honor if I could see some of you in my lecture. We are waiting for you in Brazil with our arms opened.
Best regards,
Prof. Dr. Marco Versiani
