Alternating current impedance spectroscopy technique
A more sophisticated approach to lesion detection and measurement is to characterize the electrical properties of the tooth and lesion by using the ACIST, which scans multiple frequencies. The ACIST is new and has been evaluated only to a limited extent on whole carious teeth. However, the results to date are extremely encouraging, indicating 100% sensitivity and specificity at the D1 level and only a marginal decrease in specificity at the D3 level (Longbottom et al, 1996).

Dr. Beckman,I was at the meeting at Lake Cumberland a few weeks ago and bguorht your book back to the techs on positioning. I could tell that they were thrilled (just kidding) to have another book on positioning. Anyway, they tried it and they love the positioning. It is in the room where the dental xrays are taken and stays there. I am under orders not to remove it. Just wanted to let you know how much they like it. In addition it seems that the positioning gives me a much better view of the teeth.Thanks,Don Berry DVM

I am a pediatric denitst that is pretty conservative regarding fluoridated toothpaste before the child knows how to spit. Why? Too much fluoride can cause fluorosis and cause intrinsic staining on the front teeth (incisors) and first permanent molars. I see fluorosis more and more in my patients and it is difficult to pinpoint the reason but children consuming toothpaste is a concern. I’m a parent of two young boys and am very strict about their toothpaste usage. I keep their fluoridated toothpaste out of reach too.I believe that avoiding a high-sugar diet (juice intake, sticky sugary foods, etc) is the best thing a parent can do to prevent cavities!

Wow! Great to find a post knckniog my socks off!

It’s about time sooneme wrote about this. http://qdbwwnqpud.com [url=http://pfekzrsdcle.com]pfekzrsdcle[/url] [link=http://zrtmeugc.com]zrtmeugc[/link]

Thanks, Kim.That’s a great idea for a follow-up post. I’d love to spell out some of the inomtfarion. Please feel free to share links you like.Thank you for the opinion about non-nutritive nursing and oral health concerns. I spend a fair deal of time helping families wean trained night feeders and oral health is a big part of my argument! I’ve been threatening for years to do a post on gummy vitamins .:-)Your take?

hi syed, i’m glad you like it 🙂 You’re not overstepping any boudns at all!I’m personally a fan of not always knowing the context of a poem, as it allows an individual the freedom to relate to a piece of work in shades coloured by their own history/understanding. If someone comes to their own meaningful interpretation which makes sense in their own psyche, and connects them on a deeper level to the words, then that’s just as valuable as the original authors experience, if not more so.To allow folks who don’t want to know the original process of the poem, i’d be happy to email you re: the back-history 🙂

I am very surprised that I miessd this post!We have a very similar policy at our office, in regards to actually listening to them. Go figure eh?It is amazing that something I consider a common courtesy as a professional health care provider has been thrown by the wayside.I have no problem acknowledging that it is what can help set us apart, and get better results for our patients. Hopefully everyone will catch back on.

It’s the “temporary” in the bracket with a qsteuion mark that gets me.Also, while some think that it’s not appropriate to discuss the process behind the poetry, I think it’s all fair game, should the author/poet wish to do so. It’s better to discuss the words than have others speculate and draw analysis void of meaning.MAAAAN I wish I could write poetry.You can, all you need to do is write. You won’t believe what passes as poetry. =)

‘understand deeply eugonh’. Batteries are part of the electrical system, and the fact that the problems occurred, and they haven’t yet got to the bottom of why, shows they do not understand the electrical system well eugonh.Hopefully (and very probably) that lack of understanding is only true for the new battery electrical systems.The electrical fire during flight test should also be taken into account.This is not a criticism of Boeing. Electrical systems – especially ones that have to carry significant amounts of power – are difficult to design at the best of times. These problems will be compounded when designing them to be light and to cope with differing pressures, temperatures and vibrations.The fact that the 787s have flown successfully for so long shows that whatever happened could be an edge or corner case that has been missed – extreme circumstances that are rarely encountered. And edge/corner cases can be exceptionally hard to find.An ex-colleague of mine spent six months trying to work out why a computer battery blew up during charging, which prompted a recall of thousands of units. That was back in 1985 or 1986. The only way of reproducing the problem was to leave many computers on for months at a time until another battery blew. The root cause turned out to be two PCB tracks that were slightly too close together.A hard and very expensive lesson was learnt, the expense being in engineering resource, money and reputation. Boeing and their suppliers may get a similar lesson.I hope they find the root cause soon, and develop a suitable fix. http://dexhbyqdh.com [url=http://ziterlzyk.com]ziterlzyk[/url] [link=http://wqucefurvv.com]wqucefurvv[/link]

Electrical conductance (fixed frequency) methodElectrical methods of caries diagnosis are not new. There has been recent revival of interest in fixed frequency electrical devices, which show considerable promise for detection of occlusal and approximal lesions. A device is now commercially available in The Netherlands; similar machines were produced in the United States and in Japan some years ago. The electrical detection methods are seen by many as having the greatest potential for significantly improving diagnostic performance in the years to come.

Fiber-optic transillumination methodFiber-optic transillumination is a development of a classic diagnostic aid, advocated some 20 years ago, which has never gained wide acceptance. However, it should be a regularly used tool for diagnosis of caries, in the incisor and premolar regions at least, to supplement clinical examination and bitewing radiographs. Fiber-optic transillumination has enjoyed variable success in studies evaluating its performance, possibly because of failure to appreciate that the technique, like any other, requires an extended learning phase.

Computer-aided radiographic methodComputer-aided radiographic methods exploit the measurement potential of computers in assessing and recording lesion size. In the new Trophy 97 system an artificial intelligence software (Logicon Caries Detector) is integrated: Approximal carious lesions are diagnosed and evaluated with the aid of a unique histologic database, allowing graphic visualization of the size and progression of the lesion (Figs 197a to 197c).At both the D1 and D3 thresholds, computer-aided methods offer high levels of sensitivity for approximal lesions.

Digital radiographic methodDigital, filmless, techniques for intraoral radiography have been developed for several important reasons:1. Conventional film absorbs only a few percent of the x-rays that reach it, utilizing very little of the radiation to which the patient has been exposed.2. Poor darkroom procedure can lead to both unnecessarily high doses of radiation and loss of diagnostic information.3. Development of films is time consuming, and the developer and fixing solutions are hazardous to the environment.

Conventional bitewing radiographic methodSeveral factors have contributed to the general adoption of radiographic examination as an aid to the detection and subsequent treatment of caries:1. It discloses sites inaccessible to other diagnostic methods. Radiography facilitates detection of carious lesions at an earlier, potentially reversible stage. Usually, more approximal and occlusal lesions are recorded when clinical examinations are supplemented by radiography. 2. The depth of the lesion can be evaluated and scored, eg, by the radiographic index by Grondahl et al (1977), modified from Moller and Poulsen (1973): 0 = no radiographic changes in enamel; 1 = radiographic changes in enamel; 2 = radiolucency extending to the dentinoenamel junction; 3 = radiolucency penetrating approximately halfway through dentin; and 4 = radiolucency close to the pulp.
