T he Chief Medical Officer for Wales, Dr Tony Jew- ell, has announced that David Thomas has been appoint- ed as Wales’ new Chief Dental Officer. Mr Thomas qualified as a dentist in Cardiff in 1976 and was appointed as Deputy Chief Den- tal Officer to the Welsh Govern- ment in 2010. Later in 2010 he was named Acting Chief Dental Officer (CDO) following the re- tirement of the previous CDO, Dr Paul Langmaid. Thomas has taken up the role with immediate effect and is responsible for providing high quality and professional advice to Welsh Government Ministers in relation to dentistry policy, the practice of dentistry and the pro- motion of good oral health. In a press release issued by the Welsh Assembly Gov- ernment, Dr Jewell said: “I am pleased to announce the appointment of David Thomas as our new Chief Dental Officer for Wales. “David brings to the role a background in community den- tistry, dental public health as well as a record in academia, in both a management and re- search role. He has published widely in academic dental jour- nals and has been involved in the management of Dental Postgrad- uate Education. “I would like to thank David for his work as acting Chief Den- tal Officer since the retirement of Paul Langmaid, and look for- ward to working with him in his new role.” Mr Thomas said: “I am de- lighted to have been appointed to the role of Chief Dental Officer for Wales and look forward to working with the Welsh Govern- ment Ministers on the many as- pects of dental policy and prac- tice, including promoting and improving the dental health of the people of Wales.” DT New Chief Dental Officer for Wales 3NewsJune 6-12, 2011United Kingdom Edition D T USA: Eight small teeth found in an Israeli cave raise big questions about the earliest existence of humans and where we may have originat- ed, Binghamton University anthro- pologist Rolf Quam says. Qaum is part of an international team of researchers, led by Israel Hersho- vitz of Tel Aviv University, that has examined the dental discovery and recently published joint findings in the American Journal of Physical Anthropology. Excavated at Qesem cave, a pre-historic site near Rosh Haain in central Israel that was uncov- ered in 2000, the teeth are similar in size and shape to those of mod- ern man, Homo sapiens, which have been found at other sites is Israel, such as Oafzeh and Skhul — but they’re a lot older than any previously discovered remains. “The Qesem teeth come from a time period between 200,000 and 400,000 years ago when hu- man remains from the Middle East are very scarce,” Quam says. “We have numerous remains of Nean- derthals and Homo sapiens from more recent times, that is around 60,000 to 150,000 years ago, but fossils from earlier time periods are rare. So these teeth are provid- ing us with some new information about who the earlier occupants of this region were as well as their potential evolutionary relation- ships with the later fossils from this same region.” The teeth also present new evidence as to where modern man might have originated. If the re- mains from Qesem can be linked directly to the Homo sapiens spe- cies, it could mean that modern man either originated in what is now Israel or may have migrated from Africa far earlier than is now thought.
