World news Dentaltribune|July-September, 20104 Lisa Townshend DT UK LONDON,UK/LEIPZIG,Germany: A dental X-rays and increased numbers of thyroid cancer. After factoring X-rays taken of 300 patients in a hospital in Kuwait, they found that men and women who had had up to four dental X-rays were more than twice as likely to have developed the disease than those who had never had any dental X-rays. For those patients who had had between five and nine X-rays, their risk rose more than four- fold. Although thyroid cancer is one of the least deadliest can- cers, incident rates have almost doubled in countries like Austra- lia in recent years. The findings are consistent with previous reports of inreased risk of thyroid cancer in dentists, dental assistants, technicians and X-ray workers, suggesting that sensitivity of the thyroid to radiation is not necessarily related to direct irradiation of that organ but to any exposure to ionizing radiation. Besides thyroid cancer, significant risks have been also observed for leukaemia and cancers of the breast. The researchers warned that the results of their study “should be treated with caution” because the data was based on self- reporting by the participants and the fact that other factors could be contributing to the increase in thyroid cancer cases. Further research is required to confirm the exact effect of dental X-rays, they added. “It is important that our study is repeated with information from dental records, including frequency of X-rays, age & dose at exposure,” Dr Anjum Memon, Senior Lecturer and consultant in Public Health Medicine at Brighton and Sussex Medical School, who led the study, said. “If the results are confirmed, then the use of X-rays as a neces- sary part of evaluation for new patients, and routine periodic dental radiography, particularly for children and adolescents, will need to be reconsidered, as will a greater use of lead collar protection.” (Edited by Daniel Zimmermann, DTI) DT A dental assistant looking at an X-ray.

BDZ/0909/04 Claudia Salwiczek DTI BARCELONA, Spain:WhatdoBar- celona and endodontics have in common? For me, the answer was nothing, until last week’s Roots Summit. From now on- wards, I will forever connect Gaudí, Paella and La Sagrada Família with root canals. It is certainly not an exagge- ration to say that Roots Summit 2010 had all of those lucky enough to attend falling in love with endo all over again. Organ- ised by Drs Noemí Pascual and Nuria Campo and their team, themeetingwasagrandsuccess. Long hours in the dark, yet always crowded lecture hall, despite the perfect weather, were followed by a wonderful social programme with a distinct Spanish touch. Dr Fred Barnett, who lectu- red on Trauma injuries: Long- term treatment planning based on Dx and Pulpar regenerative technique, commented: “Congr- atulations to Nuria and Noemí for organising a fantastic Roots Summit. The venue was awe- some and the lectures top notch. Roots should be proud of their efforts.” The impressive list of international speakers included Dr Giusseppe Cantatore from Italy, Drs José María Malfaz and Enrique Martínez Merino from Spain, and Drs Hans-Willi Herrmann and Jörg Schröder from Germany, to name a few. Dr Sashi Nallapati from Jam- aica held two very interesting lectures on rare and challenging cases: Dens invaginatus: Treat- ment options and Three canal premolars: An endodontic chal- lenge. Many in the audience had never encountered such cases and, thus, were absorbed in these presentations. In fact, many of the lectures were very entertaining and of extremely high quality with regard to the content as well as presentation. “It was great to see presentations that staggered me with the quality of the mate- rial and the multimedia that were shown,” commented Dr Glen van Ass, who lectured on Microscope centred practice: Ergonomicsanddocumentation. “Video through the operating microscope and still photos from some of the experts was incredi- ble. It is impressive to see the quality of the work that these teachers and talented clinicians can provide in a humble yet confident manner.” The meeting was sponsored by major industry players, like VDW, Zeiss, Dentsply Maillefer, SybronEndo Europe and Kodak. Dr John Schoeffel from the US, who introduced EndoVac—an endodontic irrigation technol- ogy system—in his lecture, also presented the product to inter- ested attendees at the Discus booth. EndoVac enables safe irrigation to apical termination with an abundant supply of fresh irrigant. Unlike positive pressure systems that use can- nulas to deliver irrigants into the canal, the EndoVac is a true apical negative pressure system that draws fluid apically by way of evacuation. “It’s not often that meetings inspire and rejuvenate people and make them look forward to future meetings,” commented Dr Nallapati. “To me, certainly, this Roots Summit has done all that. And that is a testimony to the wonderful effort of Nuria, Noemí and their team.” Attendee Dr Mahalaxmi Sekar agreed, saying that he pitied all those who had missed this event in Barcelona. A majority of the lectures, for which continuing education credits can be obtained, were recorded live and will be made available for review on www.dt- studyclub.com.

The date and venue for next year’s meeting are yet to be de- cided. But one thing is for sure: this year’s attendees are count- ing down the days.
