47 July 2011 April 2011 teASeR answer clinical hints After more than two decades of ‘TEASERS’, it has finally happened. There was just ONE* response to the April TEASER. By way of comparison, the first ever TEASER, the concept of which was the brainchild of the then ADA CEO, Colin Wall MBE, appeared in Clinical Hints, Column No 3, March 1984. In those days, postage was 30 cents, and your Columnist urged folk attempting the TEASER to accompany their answer with a clinical hint. This very first TEASER evoked 36 responses, so something must have changed over the last 27 years, and, furthermore, he has had to continue urging readers to submit clinical hints. After much cogitation, and thinking back to occasional frissons arising from outré clinical hints, your Compiler surmises that many readers would be happy to have a shot at the TEASER (and perhaps win the esteemed ADA paperweight), but are concerned that if their answer is incorrect, their name might be mentioned as its originator, and they might then have to endure disparaging remarks from insensitive companions at the golf club or the study group. The simple, successful solution to the Clinical Hints problem was to list the clinical hinters, but to separate their names from their hints. It seems to have worked. So, from this date until the time when your Columnist hangs up his mouse, only those readers correctly identifying the TEASER will be named. Incorrect responses may be mentioned, but the originators will remain incognito. So Readers, feel free to let your imaginations run riot, and suggest answers that might be regarded by some as the meanderings of unconventional minds. You will be safe from pillorying by your companions. By way of example, the sole TEASER respondent, Arthur Dent artyd0@bigpond. com said: “the carborundum cone looks like it is for finishing the margins of pre- formed crowns ...” This is an inspired answer, and wins an inscribed, decorative, pewter ADA paperweight. The cups, which * By way of emphasis, that is the numeral between 0 and 2. all readers would recognise are for a straight handpiece, are ‘Coner’s Corundum Coning Cups’. Dr Coner (clearly an alliterative enthusiast) said that he could: “shape a root so accurately with them in a few minutes that the collar of a crown of suitable size will fit perfectly”. They were 3/6d per dozen. If the collar fits, wear it! In a coincidence which beggars belief, your Compiler attended, this very day† and three hours before proofing this present copy, the Dentechno annual exhibition of products and services, geared specifically for dental laboratories, technicians and prosthetists, under the auspices of the Oral Health Professionals Association, College of Dental Technicians and College of Dental Prosthetists.‡ While there, he noted that the Austratech Dental stand was promoting the Atlantis CAD/CAM abutment preparation system, which “provides an implant foundation for the best possible function and long- term aesthetics”, i.e., a gingival margin similar to what ‘Coner’s Corundum Coning Caps’ achieve, but with a much better correspondence to the gingival margin. So here we have a computer-controlled system for preparing an excellent implant margin, viewed by a Columnist proofing the TEASER account of a similar but hand- operated system introduced 125 years earlier. That’s serendipity. Arthur then answered the second TEASER. Putting his tongue firmly in his cheek, he said: “the device from the oral hygiene magazine is an extremely rare example of the early days of holistic dentistry, and is part of the pilates /dental crossover school. The idea is that the subject stands on this device on one foot while cleaning their teeth, thereby producing total mental focus, and strengthening their core, whilst cleansing their oral cavity”. This meaningful insight is, sadly, incorrect. The device, as readers familiar with isometric drawings would have realised, is an adjustable platform, under which is a dotted-line drawing of the shaft of a dental motor, on the tapered shaft of which is pictured an eccentric disc. The various table adjustments allow the platform to be positioned over the eccentric so that the table vibrates when the motor is running. It was recommended as a way to avoid bubbles when investing inlay patterns, and could be had for $8, from the Buffalo Dental Manufacturing Co, at the top of New York State, beside the Niagara Falls. Arthur included in his TEASER answer a clinical hint. Would that all respondents were so thoughtful. The usual advantage of slips in the hat to improve chances of winning a paperweight were, for Arthur, totally unnecessary, as he was the SOLE respondent. Your Compiler hopes that this situation is unlikely to recur. Honorary Clinical Associate Professor, Barrie R D Gillings, 121 Bannockburn Road, Turramurra 2074.
