48 AUGUST 2010 clinical hints TEASER Your Amanuensis is somewhat ambivalent about offering this TEASER, presented to us by James Auld (Inverell 2360), because a similar item was used as a Mystery Object on the ABC TV program Collectors. But in the interests of getting a huge response from CH readers, what is it? Never mind that you think every dentist would recognize it. They probably won't. Assume that it is about five centimetres high. The handsome, pewter, inscribed ADA paperweight will go to the correct respondent whose slip of paper is drawn from the hat. You get extra slips for every accompanying clinical hint. Please post or e-mail to us your favourite dental or other tales which might interest your colleagues, to: Barrie Gillings, 121 Bannockburn Road, Turramurra 2074. Phone: 02 9144 3787 Fax: 02 9440 9159 e-mail: email@example.com We acknowledge, with profuse thanks, these hints from: ANZAE, R Darcy, M Hayes, M Knapp, M Maltby, N Rock and G Roberts. is wise to cover the exposed gutta percha with a GIC base. Because the two bond together, they will provide a much better seal for the gutta percha and thus reduce the chance of leakage. When patients view their teeth, they are usually standing or sitting in front of a mirror. When you are viewing their teeth, you are usually on one side, and see the teeth from a different angle. When restoring or re-contouring anterior teeth, it is a good idea to have the patient leave the chair and stand. You can then view the patient from the front, and ensure the correct crown shape and inclination. Cracked teeth are becoming less common because the ubiquitous large amalgams which were 'extended for prevention' have been replaced by adhesive resins, crowns, extraction or death of the owner. A full crown can often solve the pain problem, but initially, a conservative approach is to remove the amalgam sufficiently to expose enamel and dentine cavity walls and margins, and use a 'sandwich' restoration of GIC bonded to the dentine and a composite resin bonded to the GIC and the enamel. With luck, this will keep the crack together and eliminate pain during function. You should also adjust the occlusion to avoid pressure when chewing. If pain persists, you still have the option of the full crown or extraction. Hardly any patients enjoy having dental injections. If you can insert the needle without the patient knowing, they will sing your praises. The secret is adequate surface anaesthesia, tensing the mucosa at the puncture point, and distracting the patient at needle insertion, conventionally by asking them to "open wider". Surface anaesthetic pastes can take several minutes to work. So smear the cotton bud or roll with the anaesthetic paste, place it against the injection site and have the patient hold it there. You then explain the treatment, sort out your instruments and discuss the football scores or TV cooking shows. Take your time, as patients never complain about how long they have to hold the paste against the mucosa. Why would they? It doesn't hurt. If the marginal adaptation of your matrix band for an amalgam restoration is less than close, you will generate an overhanging margin. Your student operative dentistry kit probably contained interproximal carvers. They are excellent instruments for removing excess unset amalgam from the cavosurface margins. Use them now and avoid wasting the time required at a later appointment to cut off the overhangs with a finishing bur. no false advice Please contact Garry Pammer, Alison Lacey or Heath Stewart on: Telephone (02) 9264 1111 Fax (02) 9264 1344 email firstname.lastname@example.org website clarkjacobs.com.au Dental specialists for over 20 years
