The researchers came to their conclusion after analysing the dental patterns of more than 3,000 people. DT Putting teeth into forensics Lisa Townshend DT UK LONDON,UK/LEIPZIG,Germany: A joint research team from Kuwait and the UK has reported a link between dental X-rays and increased numbers of thy- roid 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 pa- tients 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 Aus- tralia in recent years. The findings are consistent with previous reports of in- creased risk of thyroid cancer in dentists, dental assistants, tech- nicians and X-ray workers, sug- gesting that sensitivity of the thyroid to radiation is not neces- sarily related to direct irradia- tion of that organ but to any ex- posuretoionizingradiation.Be- sides 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 cau- tion” because the data was based on self-reporting by the participants and the fact that otherfactorscouldbecontribut- ing 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 informa- tion from dental records, in- cluding frequency of X-rays, age and dose at exposure,” Dr Anjum Memon, Senior Lecturer and consultant in Public Health Medicine at Brighton and Sus- sex Medical School, who led the study, said. “If the results are confirmed, then the use of X- rays as a necessary part of eval- uation for new patients, and routine periodic dental radiog- raphy, particularly for children and adolescents, will need to be reconsidered, as will a greater use of lead collar protection.” (EditedbyDanielZimmermann,DTI) DT A dental assistant looking at an X-ray.

The study released by Global Industry Analysts, Inc., a US- based publisher of market re- search, states that dental lab- oratories are witnessing signi- ficant growth, owing to the rise in the ageing population and the subsequent demand for dental prosthetics and other restora- tives. The report also cites the increasing purchasing power of the baby-boom generation as another factor driving the market. Amongst others, the study analysed market data and statis- tics in terms of sales for Japan and other markets in the Asia- Pacific region. DT Significant growth in lab market Dentists in Taiwan have urged fast food chains in the country to label or stop selling oversized burgers with up to 8 centre metres in height. They claim that consuming these burgers, which can be twice as large as normal, could lead to temporomandibulardysfunction, an injury of the jaw.
