News Bulletin : ADA News Bulletin February 2011
42 FEBRUARY 2011 TEASER ANSWERS October answers appear in February because there is no January News Bulletin. The radiograph TEASER was submitted by Fiona Hunter (Carnegie 3163). Readers were asked to identify the feature thereon which is not normally seen on radiographs, and explain its presence. There were 15 responses, again demonstrating how much dentists like TEASER radiographs. The timing of the responses was curious. Seven of them were received over just five of the possible 40 or so days available. What is so special about 6--9 November? All respondents stated, in various ways, that the marks on the radiographs were made by someone writing, with heavy pressure, on the film packet, or the processed film acquired the marks when wrapped in paper which was being written on. They were, in order of receipt: Jeremy Rourke (Port Macquarie 2444); Michael Kirshon (mkirshon@bigpond,net.au); Abby Green (Abby.Green@adacpd.com.au); Brian Devlin (Broken Hill 2880); Akshee Shah (firstname.lastname@example.org); Peter Tadros (email@example.com); Long Ho (firstname.lastname@example.org); Ee-May Tan (email@example.com); Shane Horvath (Keilor 3036); Aovana Timmerman (Melbourne 3000); Werner Bischof (Geelong 3220); Simon Briggs (Hackney 5069); Arthur Dent (firstname.lastname@example.org); Guy Freeman (Glenelg South 5045); and Axel Ecke (Melbourne 3000). Jeremy Rourke, Shane Horvath and Arthur Dent commented that the left radiograph was mounted upside down. An unintended production hitch, but well spotted! Most respondents noted that the marks were probably the patient's name or other details, but eagle-eyed Ee-May Tan did better and opined that the marks read 'Gladys', 'tskool' and '248'. Alas, none of the respondents were correct. All answers spoke of marks being transferred to radiographic film. This is incorrect. Fiona Hunter's TEASER images were taken using her Diamaxis ScanX machine (Fig 1), which uses a re-usable radiographic phosphor plate and not radiographic film (Fig 2). The plate records the X-radiation in the same way as a photographic emulsion but needs no developing, as the image can be recorded by computer and can be viewed immediately, and also enlarged, reduced, modified and stored as required. The equipment is expensive, but Fiona says the images are excellent, instantly available and they save time. In her two examples, an assistant wrote on a sticky label attached to each phosphor plate, and the writing activated the phosphor. Because Fiona's TEASER fooled everyone, she wins a coveted, inscribed, pewter ADA paperweight. COMMUNICATIONS The News Bulletin is often read by staff and patients as well as dentists. Megan Wallbutton (Darwin 0800) trained as a dental assistant in New Zealand, and telephoned to say how pleased she was to be able to identify, from personal experience, and pestle and mortar and the amalgam/mercury balance illustrated in the August 2010 TEASER answers. We were delighted to receive her call, and most impressed that she still has the interest and also the stamina to continue chairside assisting at age 69. Simon Bender's cryptogram, which headed the August TEASER answers, was 'Peccavi', which he attributed to Clive of India announcing the capture of Sindh Province. Peccavi means 'I have sinned' in Latin, an ingenious wordplay confirmed by Ritchie McKay (Dubbo 2830), who achieved Honours in Latin at the 1949 Leaving Certificate. Les Aisen (Elsternwick 3185), Aron Bell (Melbourne 3000) and Bruce Munroe (Belmont 2280) noted that it wasn't sent by Lord Clive but by Major Fig 1. Fig 2.
