CONVERTING CLINICSSir, I would like to respond to the let-ter from G. A. Greenwood Oblique radio-graphs (BDJ 2009; 206: 221) with the solution used within the dental services of Southampton City PCT when a simi-lar problem was encountered just over a year ago, on converting some clinics to digital radiography.Southampton City PCT has had a long tradition of using the oblique lat-eral (bimolar) radiograph for assessing patients, especially small children prior to extractions under general anaes-thesia. Conventional tomographic and intraoral techniques are certainly not appropriate for some patients with either severe physical, medical, morphological or learning disabilities of any age.The oblique lateral radiograph will provide two thirds of the information that is obtained on a standard OPT for the dose equivalent of a pair of bitewing or molar periapical views (depending on sensitivity of receptor) and can be easily taken under sedation or anaesthetic.The problem was overcome by using an OPT cassette containing a digital plate produced by Kodak Practiceworks. The plate is then easily read by their CR7400 reader which is about the size of a bread bin. The image may be viewed imme-diately on a computer screen, stored in the digital record for that patient and/or printed in various formats. This system allows great flexibility as it also reads small intraoral plates which are similar in size and thickness to conventional fi lm. At installation the plates will be cali-brated to the reader and X-ray source. The OPT cassette is longer and slightly narrower than the bimolar half-plate but is very user friendly as you can posi-tion it easily. Right and left views can be taken on the same plate and there is noneed to shield half the plate from radia-tion scatter to prevent ‘fogging’.The X-ray source is a standard 70Kvintraoral machine. The machine wassupplied with a rectangular collimatorthat is exchanged for a round one foroblique lateral views only. Neither I, norany other members of staff have man-aged this view satisfactorily with rec-tangular collimation.This new approach to an old tech-nique will therefore require the follow-ing equipment: OPT cassette containinga digital plate (re-usable), digital readerlinked to a computer, screen and printerif required. This may take up room in anoperating theatre or could be sited in anadjacent room.Regarding printers, the dental servicehas had better results using a good qual-ity inkjet printer onto matt photographicpaper than with a laser printer. You canalso print onto acetate if you prefer. Med-ical grade printers are available but wereprohibitively expensive for our service.Radiographs are stored and viewed inthe electronic record for the patient andonly printed and forwarded if the patientis referred to another service or clinicthat cannot access the record.I hope this may be of some help.A. Keirby , RomseyDOI: 10.1038/sj.bdj.2009.520OBLIQUE LATERALSSir, I was pleased to read the letter by G. A.Greenwood (BDJ 2009; 206: 221). It wasas if I had written the letter myself sinceI also as a Senior Dental Offi cer practis-ing special care dentistry for many yearshave found oblique lateral radiographsvery useful when looking after peoplewith severe disabilities including thoseexamined and treated under conscioussedation and general anaesthesia. IndeedI often wonder why this technique is notused more widely by colleagues lookingafter similar patients. If it were, I suspectthe radiographic industry would makeappropriate digital sensors and cassettesmore widely available.In the mean time I have found eitherusing a digital DPT cassette or a digital truelateral cephalometric lateral skull (lateralceph.) cassette to fulfil the requirementalthough these are a little larger than thestandard wet-film cassettes I have usedfor oblique lateral views.K. Dalley, WarsashDOI: 10.1038/sj.bdj.2009.521NO ADVERSE RESULTSSir, when I last checked (approximatelytwo years ago), cassettes used for obliquelateral radiography were available byspecial order from Minerva Dental; fi lmswere available from Henry Schein.The intensifying screens with thesecassettes are calcium tungstate and thecorresponding fi lms are the ‘blue’ fi lms.This combination is much slower thanspeeds achieved with rare earth screensand corresponding fi lm.I have used DPT cassette and fi lm withthe lateral oblique technique with noadverse results. I don’t see any reasonwhy cephalometric cassettes and fi lmcould not be used.The typical size of the lateral obliquecassette is 15 × 18 cm, the cephalomet-ric 18 × 24 cm and the DPT 15 × 30 cm.Using either the cephalometric or DPTcombinations should result in a lowerdose, as both are available with rareearth screens.Should Mr Greenwood not wish to trythese alternatives and can source theSend your letters to the Editor,British Dental Journal,64 Wimpole Street,LondonW1G 8YS****************Priority will be given to letters lessthan 500 words long.Authors must sign the letter, whichmay be edited for reasons of space.Letters to the Editorfi lm, I would be happy to send him a 15 × 18 cm cassette with screens, which I do not use anymore.B. Fanning By emailDOI: 10.1038/sj.bdj.2009.522USEFUL CONTACTSir, I was also a student at the London Hospital, and still use the lateral oblique technique. I am able to obtain cassettes, intensifying screens and 13 × 18 cm X-rays. I hope this is useful.A.

He is a painter/decorator and migrated to the UK one year ago.He was anaemic, with a normal gen-eral examination. An abdominal exami-nation was unremarkable and chest and abdomen X-rays were normal. Blood and biochemical tests showed iron defi ciency anaemia and a normal kidney and liver profi le.He was treated symptomatically with little improvement. On re-examination, he was noticed to have a bluish discol-ouration along his gum (Fig. 1). Further enquiry about his occupation revealed a heavy involvement in paint stripping old buildings over the past eight years. The blood fi lm showed ‘basophilic stippling’ and serum lead levels were high.A central nervous system examination was normal. He was treated with chelat-ing agents with a good response.Lead poisoning is a recognised occu-pational hazard. Lead containing paints are still encountered in old buildings and paint stripping presents a high expo-sure risk. Inhalation is the main route of exposure. Despite different legislation to control exposure, many Eastern Euro-pean countries have no strict occupa-tional health regulations. In other parts of the world, hazard from lead smelting and lead additives is a major problem for workers and consumers, for exam-ple: China and India (synthetic dye and lead paint and the 2007 Chinese export recalls). In the Middle East, tetra-ethyl lead is still added to petrol, posing an environmental risk.Poisoning can be acute or chronic. Diagnosis can be diffi cult as symptoms and signs are non specifi c and present late until high blood lead levels are reached. Patients may present with nau-sea, vomiting, abdominal pain and con-stipation. CNS involvement can cause numbness and pain in the extremities, lethargy and mood disorders, muscle weakness, headache and memory loss. It can lead to miscarriage in women and reduced sperm count in men.In 1840, Henry Burton described a bluish line in the gum following expo-sure to lead (Burton’s line). Lead sul-phide is produced by the reaction of lead with sulphur ions produced by oral bac-teria which present as a narrow blue line alongside the edge of the gum in both upper and lower jaws. It is a reliable sign, but poor oral hygiene can produce a similar boratory fi ndings of anaemia and punctuate basophilia ‘basophilic stip-pling’ is due to lead interference with haemoglobin synthesis and is not spe-cifi c. Lead poisoning should be con-fi rmed by biochemical testing of blood lead levels. An L-line X-ray fl uorescence technique can measure cortical bone lead content.Treatment includes preventing further exposure. Protective masks and clothing are important precautions as well as rec-ognising jobs with high risk. Removal of lead from the body using chelating agents is the most important treatment. It is a slow process and requires monitoring of lead levels. Ethylenediaminetetraace-tic acid can be given intravenously,sometimes combined with Dimercaprol (BAL). Edentate calcium disodium (EDTA calcium) and D-penicillamin are other useful agents.A. Khalil, PerthDOI: 10.1038/sj.bdj.2009.524WARRANTING THE EFFORTSir, over the last seven years, there have only been a small number of changes in the DPF/BNF antibiotic prescribing guidelines for dental practitioners, with the removal of three indications: oral-antral fi stula, acute suppurative pulpitis and antibiotic prophylaxis.1,2While the general DPF/BNF advice that ‘Antibacterial drugs should only be prescribed for the treatment of dental infections on the basis of defi ned need’ has not changed over that period, there has been a more general recognition of the need to limit the development of resistant strains by optimising prescrib-ing patterns.3 However, recent research found that high levels of oral antibiotic prescribing in the absence of local mea-sures persists and is of concern.4Over a period of time I developed an antibiotic prescribing approach, which used available authoritative advice resources in order to optimise thera-peutic use. This may be summarised as follows:Examination with particular reference • to BNF adviceAdopting a local measures approach • Where appropriate recalling patients • within 24 hours to review their condition in order to determine whether it was stable, resolving or worseningProviding patients with OOH contact • advice, analgesics advice and advice to attend A&E in the event that a swelling developed which began to embarrass the airwayProviding reassurance to patients on • the clinical approach being adopted, frequently with reference to the limitations of antibioticsWhere appropriate seeking additional • professional pharmacological advice Immediate referral for patients with • very severe dental infections, which risked embarrassing the airway (as I recall there were two such cases over 15 months both of which wereLETTERSFig. 1 Bluish discolouration along the patient’s gumdiscussed with the on-call maxillofacial clinician prior to referral).In order to assess the outcome of this approach, a text backup document gener-ated by keylogger software was analysed for keywords potentially relevant and rel-evant to acute dental infections over the period November 2007 to January 2009. Over that period only two instances of prescribing antibiotics for a single acute dental infection were identified (I had originally believed that there were three separate episodes of such antibiotic pre-scribing – unfortunately the full clinical software package is not readily search-able at the text level, currently). The keywords analysed for the same period and associated number of instances are given in Table 1.Therefore, during that time I estimate that I treated approximately 600-800 emergency patients (dental bureau refer-rals, new patients and past patients). I would add that I have also not found it necessary to prescribe antibiotics in the period January-April 2009.In England, in the period 1 April 2007 to 31 March 2008, approximately 20,000 dentists (with NHS activity)5 issued 3.7 million NHS prescriptions for antibiot-ics in the fi nancial year 2007/8 at a cost of £7.89 million, in England.6 Therefore on average each NHS dentist prescribed 185 courses of antibiotics per year with a total cost of £394. The respective FTE figure per dentist may be expected to be higher and private prescribing per dentist may increase FTE fi gures for all dentists in England, still further. If my personal case load for acute dental infections is typical of the average prac-titioner, then my experiences would suggest that prescribing and associated costs could be reduced to approximately 1% of current levels.3To be candid, such an approach to anti-biotic prescribing can be time consuming and stressful, particularly where patient ‘expectations’ are not being met and where prescribing criteria are close to being met. Furthermore, the costs of the additional effort probably substantially outweigh the fi nancial savings to the NHS in reduced prescription charge expendi-ture. However, when implemented and established, I believe the benefi ts to the patient and the clinician more than war-rant the effort. I also believe that similar approaches will have been pursued by many colleagues and dissemination of their approaches and experiences would be of benefi t to the profession.P. McCrory, Radcliffe1.

The fi rst dental image shown is a photograph of teeth and a shade guide together to assist a technician who is not present. This is an excellent, almost essen-tial procedure for the majority of dentists who work with a distant technician. Unfortunately, as Gordon Christensen illustrated in the CRA newsletter of May 2005, the method Dr Ahmad shows reflects a common error as the shade guide is not in the same plane as the teeth. A preferred method is for a single selected shade tab to be inside the oral cavity, so that the illumination for shade tab and teeth is the same.When the technique Dr Ahmad shows is used, the shade guide will normally be signifi cantly lighter than the teeth.J.

产品性能介绍 Otis复合钢带 在现今的曳引电梯行业，存在着两种曳引媒介的形式：钢丝绳与复合钢带。钢丝绳的曳引电梯已经有了上百年的历史，而复合钢带为上世纪90年代的产物，正以迅猛的速度改变着电梯行业，并将在不久的将来取代钢丝绳。正是由于钢带在电梯解决方案中的诸多优点，使得他具备颠覆性的竞争力。
钢丝绳 Otis复合钢带 寿命长 传统钢丝绳的曳引方式为，钢丝绳在一截面为V型的绳槽内，由V型绳槽的夹角对钢丝绳表面的压力产生放大效果，从而增大钢丝绳与曳引轮之间的摩擦力，才能得
到足够提升轿厢的曳引力。金属与金属直接接触产生的强大积压，以及钢股之间的受力不均，不仅使钢丝绳容易出现局部破坏，出现断丝断股的缺陷，还会使曳引轮的轮槽受到磨损，影响运行性能，如果不能及时更换，甚至会出现溜车的情况。
Otis复合钢带，表层是耐磨的聚氨酯，内层包裹着490根高强度钢丝，聚氨酯表层能提供充足的摩擦力，并避免了金属之间的直接接触，即保护了钢股，亦保护了曳引轮。钢带内部的钢股横向排开，均匀的承受着拉力，更大程度上降低了钢股之间受力不均带来的恶劣工况。正是由于以上结构优势，Otis复合钢带能达到20年的使用寿命。
a) 使用传统钢丝绳曳引方式时，由于在绳轮与钢丝绳之间有金属之间的直接摩擦，会产生钢丝绳落槽声。随着磨损的加剧，落槽声会变得越来越明显。
Otis复合钢带由于消除了金属之间的直接接触，杜绝了曳引摩擦噪音，即便使用时间再长，也不会改变这一特性。
免润滑 b) 传统钢丝绳由于钢丝之间存在相对摩擦，需要有内部润滑，所以在钢丝绳的中心有一根浸油麻芯，会在若干年时间内溢出油脂。在电梯使用的头两年，油脂溢出迅速，在温度较低环境下油脂会凝结在钢丝绳表面，干扰运行性能，降低曳引力；大约在第五-第六年，麻芯中的油脂接近枯竭，钢丝绳内部的无油摩擦加剧，在这种情况下，钢丝绳会加速损坏。
油脂不仅增加曳引系统不稳定性，油脂的挥发也会污染电梯井道内的空气，影响人体感受；劣质润滑油甚至会产生致癌挥发物，润滑油在潮湿环境下为细菌提供了滋生环境，威胁乘客健康。Otis复合钢带消除了曳引系统中的油脂，避免以上风险的发生。(建议同时选配滚轮导靴，2013年7月1日以后适用) 同样，GeN2主机与导向轮均采用密封轴承，完全杜绝油脂产生。
GeN2曳引机---噪音低 除了消除曳引轮与钢带之间的摩擦噪音，GeN2主机在抱闸控制，避震设计与高防护等级，使得GeN2主机的噪音远远低于钢丝绳产品。
由于GeN2主机的绳轮直径仅为同规格钢丝绳主机的1/4，小直径带来高转速，亦使抱闸转矩降低了75%，抱闸转矩的降低使抱闸所产生的碰撞噪音大大减小。此外，包裹在机壳外部的PU橡胶具有良好的隔音减震效果。
而在电机侧，由于电机机壳有良好的密封性，达到IP51的防护等级，除了在防尘方面有很好的表现，其噪音也被很大程度的隔绝在机壳内部。
即便对人耳难以捕捉的低频震动，GeN2主机也有着精心的考虑。在主机底部的减震橡胶有针对低频震动明显的吸收效果，防止低频震动通过主机承重梁与导轨传递到建筑，即便在临近井道的房间，也可以享受到安静的环境。
综上所述，GeN2主机的运行噪音能达到55分贝，远低于同等的钢丝绳70分贝的噪音等级。
寿命长 噪音意味着摩擦与碰撞，而摩擦与碰撞意味着设备的损耗。 对于曳引轮，由于没有了金属之间的摩擦，曳引轮在正常工况下不会磨损； 在电机侧，由于有较高的防护等级，一般的尘埃难以进入电机内部，电机的寿命得到延长。 在抱闸侧，隔音橡胶不仅仅隔绝了噪音，也是使尘埃难以进入抱闸内部，使闸衬一直处于理想的工作状态，因此寿命也得到延长。
对于转子线圈，由于GeN2主机在启动时要求的启动力矩小，所以所需的启动电流很小，这大大降低了线圈绝缘层的损耗。
轴承一直是曳引机使用寿命的瓶颈，GeN2主机与传统钢丝绳主机均采用滚动轴承，但GeN2主机采用完全免润滑的密封轴承，确保了轴承的寿命。
GeN2主机采用的两端支撑结构，使两个轴承能均分曳引轮受到的负载。但传统钢丝绳主机采用悬臂结构，靠近曳引轮侧的轴承往往要承受超过曳引轮负载的压力。滚动轴承的特点为不怕高速，只怕高压，GeN2主机迎合了这一个特性，使得轴承的寿命进一步加长。
GeN2主机采用的碟式抱闸刹车盘在制动时产生延圆周方向均匀的制动力，对主轴不会产生径向冲击。传统主机常采用的鼓式制动器由于抱闸过程中，两侧的制动块动作往往不同步，对主轴的冲击很难相互抵消，而这冲击被传递到轴承上，加速了轴承的失效。
综上几点，GeN2的主机在普通的工况下寿命长达20年之久，远远优于钢丝绳主机。 GeN2主机外观 传统主机外观图

运行平稳 永磁同步电机与ACD控制系统组成一个闭环系统，控制系统不仅提供电机动力与运转指令，也可接受主机内编码器提供的脉冲信号，来对电梯的运行进行校正。由于GeN2曳引机的转速是传统钢丝绳曳引机的4倍，它所反馈的脉冲信号较后者密集很多，（22,828/s vs 11,414/s），精确的ACD控制系统与密集的脉冲反馈，确保了GeN2电梯的运行性能在14mg以下(而国标对传统钢丝绳曳引系统要求为30mg)。
体积小 GeN2主机由于采用了小轮径使得GeN2主机结构非常紧凑。尤其是在高度方面，GeN2 曳引机降低了机房(顶层-无机房)的高度，使建筑设计更加自由。
ACD控制系统---精密控制 ACD控制系统是Otis针对亚洲市场推出的，双32位模块化、数字化控制系统——即主控制板采用32位CPU，变频器的控制板亦采用32位CPU，将控制效率大大提升。主控板和变频器之间采用CAN-BUS通讯，取消了接口板，减少连线数量，提高通讯效率。32位高速数字信号处理器配合先进的控制算法，使电梯在加速、减速、制动平稳，乘坐更加舒适，同时缩短楼层间的运行时间。
内置时钟 ACD控制系统内置时钟系统可以使电梯在不同的时间段处于不同的状态，例如：您可以设置从0:00am ~ 6:00am电梯处于锁梯状态，以节省能耗；或者8:00pm ~ 8:00am电梯的风扇或报站钟，处于关闭状态，为住宅营造安静的环境。
传统的钢丝绳电梯称重方式主要有两种，一是利用接近开关测量轿厢在负载下的沉降，以此判断轿内载荷，这种测量方式会受到轿内载荷分布不均，轿底减震垫老化等因素的影响，使得称重开关准确性难以保证；二是检测绳头板受到的压力，来确定轿内载荷。但这种方式也会在各个绳头载荷分布不均的情况下得到误差较大的结果。
电子连续称重 GeN2电梯装备了紧密的电子连续称重装置，该装置直接安装与钢带上，检查轿厢侧每一根钢带的受力大小，通过累加计算后将重量值反馈给控制柜，由于有了准确的重量信息，控制系统为驱动主机提供恰到好处的提升力，使轿厢平稳启动。 接近开关称重 绳头压感称重 GeN2钢带电子连续称重
能源再生变频器 此变频器引用奥的斯能源再生的专利技术，最大的特点就是节能，能源再生变频器可将电机产生的电能通过滤波处理将清洁电能反馈回电网输入侧，供电网中的其它用电设备使用，如，电扶梯、中央空调、照明设备等。

32位高速数字信号处理器配合先进的控制算法，使电梯在加速、减速、制动平稳，乘坐更加舒适，同时缩短楼层间的运行时间。
轿厢 托架 绿色环保 变频器内置高性能滤波装置，消除谐波污染，让反馈回输入侧的电能更清洁，符合CE标准，特别适用于医院、科研院所等具有要求防辐射的场所。
欠压适应性强 能源再生变频器运用弱磁控制技术可确保曳引主机在低于额定电压30%的情况下不会停止运行。特别适合电压波动较强的场所使用。
兼容多种通讯协议 可与CAN-Bus和RS422两种通讯接口兼容。 永磁同步门机 GeN2电梯不仅在曳引机上采用了永磁电机技术，在门机上也采用了这一技术。永磁同步电机直接驱动，取消减速箱后可以提高传动效率；结构简单，节省建筑空间；
部件数量减少，可以减少门机整体故障率；采用门电机与编码器一体化设计，并增加外罩可以防尘、防潮、防外部机械干扰，增加产品适用的稳定性；
