47 AUGUST 2010 clinical hints THE WONDERS OF THE ENGLISH LANGUAGE AND THE ROMAN ALPHABET It came as a complete surprise to your Wordsmith that the letters AN can be preceded by the letter B, C, F, M, P, R, T, V and W, and convey nine distinctly different meanings. You can try the same scheme with --ANKER, with the same result. AUSTRALIAN GEOGRAPHIC In January 1986, millionaire businessman, adventurer and philanthropist Dick Smith published Volume No 1 of the Australian Geographic. It has been a total success, and has entered into Australian folklore. Your Recorder's latest copy is Volume No 98. It carried a letter to the Editor from Ian Gasking, of Perth, Tasmania, (postcode 7300) adding information to the Volume 97 story 'Red Dawn, Rolling Thunder', describing a storm and flood in Alice Springs in 1964. He said: "Red torrents cascaded across footpaths and flooded the streets, racing for the dry bed of the Todd River. The ducks panicked and hid under the cars; it had never rained in their lifetime." These ducks could be the ones that learned to fly backwards to keep the dust out of their eyes. The same issue carried a story entitled: 'Waiting for the Lirra Djama'*, and sub- headed: Dedicated dentists are improving Aboriginal Australian health, from the teeth down. We join two of them as they visit remote communities in Arnhem Land. A team of 12, (two dentists, two anaesthetists, two dental assistants, a clutch of specialist nurses and a couple of AGI coordinators) are a team working for the Australian Government Intervention (AGI), and provide the dental treatment carried out at Gove District Hospital. The two dentists are Denise Salvestro and her professional and life partner, Neil Lanceley. They are both members of the ADA, and the only two ADA members listed in Northeast Arnhem Land, where they initially ran a private practice at Nhulunbuy. They now do regular tours to provide dental treatment at a number of Aboriginal communities. Denise and Neil graduated from Sydney University in the early 1970s. Neil's Yearbook Valediction credits him with "an almost legendary flair for improvising and economizing", and notes that he comes from a long line of dentists. Denise's Valediction notes that she was dux in Primary School and School Captain of Griffith High School. She had a long list of credits and a distinction in surgery, and acquired a little car, "in which she managed to lock two sets of keys on her first trip". They have worked with the Aboriginal community for ten years, and are in the team of about 30 health professionals and 115 resident staff working for the Northern Territory Government. This work is important. Compared with the general population, Aboriginal Australians have twice as much untreated dental caries, 12 times as much hepatitis B and 30 per cent more cardiovascular disease and they die earlier. Recent research indicates that untreated dental disease is not just painful, unsightly and unpleasant; it can contribute significantly to poor general health. We hope that the dental teams who work in these isolated communities and put up with uncomfortable living conditions, isolation, a trying climate and lack of creature comforts can find the time to tell News Bulletin readers about their experiences. Your Compiler is proud to be in a profession and an Association which has members such as these. We should give better recognition to their contributions to the community. REUNIONS All save the most recent graduates have attended some of these, and they show us how quickly some of us depart this world, and how quickly others look really old (compared to ourselves). What follows is a summary of what you might expect, from a CH reader whose name has been, sadly, lost in an inefficient filing system, but thanks. Reunion at age 40: We chose the Ocean View Restaurant, because the waitresses have low-cut blouses, are young, and are quite attractive. At age 50: It was agreed to meet at the Ocean View restaurant, because the food is very good and there is an excellent wine selection. At age 60: The Ocean View restaurant was chosen because the atmosphere is quiet and peaceful, and there are beautiful views of the ocean. At age 70: Because some of the group have slight disabilities, the Ocean View restaurant was chosen because it has excellent parking, is wheelchair-accessible, and also has a lift. At age 80: The group had an extensive discussion as to where to meet, and decided on the Ocean View restaurant, because they had never had a reunion there before. MODERN POLICING The days of Sherlock Holmes and his magnifying glass (a pretty fiction) have long gone. Today's police forces can achieve amazing results. There was a recent world first for the local rozzers when a criminal was identified years after the crime using DNA analysis. Nothing new there, you say. Wrong! The police had preserved a leech found at the scene of the crime, sequenced the DNA in its blood meal and established that it did not come from anyone found at the scene. Around a decade later, the police found a match with a recently arrested suspect for another crime. Such amazing technology must surely be a significant deterrent to aspiring criminals with brains, if there are any such. BATTERIES There are now many different types of battery available, but one that is especially useful is the Lithium-Iron (aka Lithium Ion) battery. This recent development is used in mobile telephones and laptop computers because of its long life and high output. With electrically powered vehicles becoming increasingly popular, we are going to see more and more novel battery designs like this. CLINICAL HINTS These hints are not promoted or endorsed by your Columnist or the ADA. Your colleagues submit them because they have found them helpful but it is your decision whether to use them. If you don't like a hint, don't write a letter of complaint; just send in a better hint. You can be anonymous or you can use a pseudonym, and your colleagues won't tease you because no one can tell which hint is yours. 'Dry Tips' (molnlycke.com/campaigns/ dryTips/index.asp) provide control of parotid saliva and also retract and protect the cheek. You then have excellent access to the molar teeth. When the tooth of interest is a second or third molar, and there is little space between tooth and cheek, you may find that reversing the Dry Tip will further improve access. The interceptive appliance Regulator III of Frankel is an effective orthodontic appliance if you have good patient compliance. But you may find that after +/- three months there will be about a millimetre of space between the lower labial bow and the lower incisors. The bow is a rigid connector, and is difficult to adjust. But you can fill the gap by bending a wire of the appropriate gauge to fill the gap, then tack weld and solder it to the bow and continue with the treatment. If you plan use a resin-bonded material to restore an endodontically-treated tooth, it * Tooth worker(s) in Yolngu matha, the Aboriginal language of East Arnhem Land.
