35 SEPTEMBER 2010 TEASER The June 2010 TEASER had two parts. The first was courtesy of author, Bill Bryson, who noted in one of his books that a letter addressed: HILL JOHN MASS was delivered successfully by the US Postal Service. Readers were asked to deduce the correct address. The answer is: JOHN UNDERHILL ANDOVER MASSACHUSETTS Eight answers were received, and all were correct. They are, in order of receipt: Simon Bender (Chatswood 2067, a virgin respondent, and thank you for the two word puzzles); Faisal Rana (Newcastle 2300); Peter Klein (Cheltenham 3192 plus a clinical hint and a kind comment); Yong Kho (Adelaide 5000, who Googled <Hill John Mass Bill Bryson>, clever chap!); Benlee Yap <benlee.yap@student. adelaide.edu.au> who took time off from studying for an exam the next day; Anthony Hill (Southbank 3006 and thank you for the three potential TEASERS); John Paterson (Auchenflower 4066, who has read the relevant Bill Bryson book and gallantly ruled himself ineligible, but we didn't, and thanks for the four clinical hints); and finally, Brian Hannath (Wodonga 3690). Thirteen name slips were prepared (eight for the correct answers, and five extra for the clinical hints), folded and placed in your Columnist's old graduation mortarboard. His life partner drew out the name Paterson, so John wins the handsome, inscribed, pewter ADA paperweight. There was no favouritism. His chances were five out of 13, or 38 per cent. Call Margaret for verification of complete honesty. Moral: send in lots of clinical hints with your TEASER answers. The second TEASER was much more of a challenge. We required: "An explanation of this dental toolkit of earlier times, patented by SS White in 1914. The longest item measures 30 mm. What is its purpose?" Scott Jenkins (Melbourne 3000) thought that: "when all these pieces are placed together, it is a crown/bridge remover." This is in the right area, but incorrect. Peter Stradz (Reynella 5161) said: "I think this month's TEASER instrument is a post- puller. By the look of the hook on the end of one part it may be able to be used to loosen a crown as well". Bill Hannath (Wodonga 3690) said: "the tool kit appears to be a crown/post remover with a trepan". Your Expositer is pleased to advise readers that the kit contained instructions, in English, French, Spanish and Portugese (pictured) but is not so pleased that the two end-cutting burs were missing from his kit, and the 30 mm tool (left of Item 1) with the 'hook' described by Peter Stradz, was not shown in the instructions, nor was the 'mystery item' (between Items 3 and 4) with its possibly broken tip and its round washers. But we do know that SS White called the device a POST EXTRACTOR. We think that the item on the left, which has three cutting blades on its end, is for cutting away dentine and filling material, preparatory to preparing the broken post for threading. We added the sewing needle to represent what we presume was a guiding rod (missing) for cutting down to the post.
