carabelli - 23 Jan 2005 03:58 GMT Other than the obvious.................
Jan Drew says she is a retired Day Care owner and claims to have finished High School. She is not a dentist and has no background in science. She lacks appreciation of what constitutes proper research and the Scientific Method, because they are evidentially beyond her capacity to understand. Instead she has embraced Alternative treatments, Hulda Clark's writings and anything else she can find on the Misinformation Highway that she thinks will support abandonment of mainstream dentistry.
Several dentists and others with an education in the sciences have attempted to discuss some of the URLs, abstracts and articles that she posts. Some have merit, others (especially those selling *snake oil*) have none. She is unable to distinguish between those two. When others have tried to debate and/or discuss she has consistently changed the focus. If a source she has posted is politely challenged, even if only to discuss its' merits and/or shortcomings, the word lie or some derivation of it will follow shortly. Regrettably she has gone further with some childish insults and even more regrettably others have stooped down to her level. Unfortunately, this has been the only effective way to interact with her.
Then, if she feels the need, she plays her trump card, the Bible.
Most of the professionals posting here aren't playing her card game anymore. It is a waste of our time to challenge each and every post, however we do not support her views. Her posts leave the dentally uninformed easy prey for the charlatans out there who are ready to take your money, give you false hope, or worse.
If you choose to read her posts, do so with a jaundiced eye.
NB this is also from a poster that thinks her own ISP is attacking her computer.

He never takes a position, citing the fact that more research needs to be done on the amalgam issue. Cleverly thinking himself above the fray, superior in some way and the rest of us to stupid to notice. I wonder if he statements merit EVEN the respect of Dentists on the list who baltantly repeat false information.
Take note Carabelli, you game is up. A quaterback who throws no interceptions or completes any passes deserves far LESS respect than the dentists who set themselves up day after day to be sacked by Jans amalgam science.

The studies found that the amount of mercury excreted in the urine was proprotional to the number and size of fillings in the victim's mouth. Moreover many oral habits such as chewing gum, clenching or grinding greatly increased the amount of mercury released and absorbed.

6. Amalgam Fillings Largest Source of Mercury by Far
Based on a number of studies in Sweden, the World Health Organization review of inorganic mercury in 1991 determined that mercury absorption is estimated to be approximately four times higher from amalgam fillings than from fish consumption. Recent studies have confirmed this estimate and shown that the amount absorbed can vary considerably from person to person.
7. Gold Crowns, Gum, Bruxism, Computer Monitors Increase Release of Mercury Significantly
Gum chewing, bruxism (grinding of teeth), computer terminal exposure, presence of gold fillings or gold crowns (even if covering mercury fillings), teeth brushing, braces and even chewing food cause the release of significantly increased amounts of mercury from the fillings in one's teeth.
8. Cumulative Poison Builds Up in Organs
Mercury released from fillings builds up in the brain, kidneys, liver, pituitary, adrenals and other parts of the body.
========
According to the World Health Organization the general sources of mercury in the body are: Breathed Air (.040 micrograms), Fish (2.34 micrograms), Non-fish food (.25 micrograms), Drinking-water .0035 micrograms), mercury vapor from dental amalgams (3 to 17 micrograms).
*****The mercury vapor from dental amalgam alone is a bigger source than all the other sources together.*******

Contact &Occupational Dermatitis Clinic, Skin &Cancer Foundation, NSW, Australia. Oral lichenoid lesions (OLL) or lichen-planus-like lesions are often idiopathic. Our aim was to determine whether OLL can be caused by allergy to mercury in amalgam fillings, and whether resolution of OLL occurs after replacement of amalgam with other dental fillings. Patients with only OLL (except for 1 case with cutaneous lichen planus) referred for patch testing during 1985-1994 to the Contact and Occupational Dermatitis Clinic of the Skin &Cancer Foundation, Darlinghurst, were reviewed. Patch tests were performed with 1% mercury, 1% ammoniated mercury, 0.1% thimerosal, 0.1% mercuric chloride, 0.05% phenylmercuric nitrate and an amalgam disc, using Finn Chambers occluded for 2 days, 19 patients (17 women and 2 men; age range: 28-72 years) had OLL in close contact with amalgam fillings and showed positive patch test reactions to mercury compounds, 16 out of 19 patients had their amalgam fillings replaced. In 13 patients, the OLL healed. 1 patient had marked improvement. 1 patient had no improvement and developed multiple oral squamous cell carcinoma. In conclusion, OLL can be caused by allergy to mercury in amalgam fillings. Replacement of amalgam with other dental fillings usually results in resolution of OLL and is recommended for cases with positive patch test reactions to mercury compounds.

In vitro lymphocyte proliferation test in the diagnosis of oral mucosal hypersensitivity reactions to dental amalgam.
Laine J, Happonen RP, Vainio O, Kalimo K.
Department of Oral Diseases, University Central Hospital of Turku, Finland.
Patch testing was carried out in 23 patients with oral lichenoid lesions (OLL) topographically related to dental amalgam fillings. Twelve patients displayed positive reactions to several mercury compounds, whereas 11 patients were negative. An in vitro lymphocyte proliferation (LyPro) test was carried out using different mercury compounds and other metal salts. Mercuric chloride and phenyl mercuric acetate caused positive proliferation in 3/12 patch test-positive and in 5/11 negative patients. One out of seven healthy control subjects had a positive LyPro result. The mean stimulation index (SI) values between the patient groups or compared with the control subjects did not differ significantly. Zinc, tin, copper or silver salts caused in vitro lymphocyte stimulation in most of the patients and in healthy control people. Total (14) or partial (4) replacement of amalgam fillings was carried out in 18 patients. Complete healing of lichenoid lesions was seen in 4/6 LyPro test-positive and in 5/10 patch test-positive patients at follow-up examinations 12 months after the replacement of amalgam fillings. The in vitro proliferation assay seems not to be a specific test for identifying the patients who would benefit from amalgam replacement.

Does mercury from amalgam restorations constitute a health hazard?
Weiner JA, Nylander M, Berglund F.
National Board of Occupational Safety and Health, Solna, Sweden.
Amalgam is the most extensively used implant material in dentistry. There have been no clinical trials of this substance and there are no epidemiological studies that allow any conclusions on the safety of amalgam fillings. Amalgam restorations continuously emit mercury vapour, which is absorbed in considerable quantities via the lungs. A comparison with dose-effect relationships, obtained in occupational studies, for certain effects on the kidneys and central nervous system (CNS), suggests that individuals with unusually high emission of mercury from amalgam fillings are at risk. It is unclear whether or not clinically significant effects could be expected. The limited sensitivity of available occupational studies, together with insufficient knowledge of possible host factors affecting resistance to mercury, implies that other more severe effects in susceptible individuals cannot be excluded. Information on long-term effects on organs other than brain or kidney is sparse. Animal studies suggest the possibility of immune system reactions to mercury, i.e. development of autoimmunity, that are not primarily dose-dependent, but rather depend on genetic susceptibility. From a toxicological point of view, amalgam is an unsuitable material for dental restorations.

Environmental medicine, part three: long-term effects of chronic low-dose mercury exposure.
Crinnion WJ.
Healing Naturally, 11811 NE 128th St., Suite 202, Kirkland, WA 98034, USA.
Mercury is ubiquitous in the environment, and in our mouths in the form of "silver" amalgams. Once introduced to the body through food or vapor, mercury is rapidly absorbed and accumulates in several tissues, leading to increased oxidative damage, mitochondrial dysfunction, and cell death. Mercury primarily affects neurological tissue, resulting in numerous neurological symptoms, and also affects the kidneys and the immune system. It causes increased production of free radicals and decreases the availability of antioxidants. It also has devastating effects on the glutathione content of the body, giving rise to the possibility of increased retention of other environmental toxins. Fortunately, effective tests are available to help distinguish those individuals who are excessively burdened with mercury, and to monitor them during treatment. Therapies for assisting the reduction of a mercury load include the use of 2,3-dimercaptosuccinic acid (DMSA) and 2,3-dimercato-1-propanesulfonic acid (DMPS). Additional supplementation to assist in the removal of mercury and to reduce its adverse effects is discussed.

Seventy-five subjects aged 20 to 57 with 1 to 15 fillings of silver amalgam were examined. The level of mercury vapors in the oral cavity was assessedusing an AGP-01 device and the method developed by the authors. Emission of mercury vapors in the oral cavity increased with the number of fillings. The concentration of mercury in the oral cavity depends largely on the number ofsilver amalgam fillings and less so on these fillings' length of service.Adv Dent Res 1992 Sep;6:110-3

The purpose of this paper is to examine and report on studies that relate mercury levels in human tissues to the presence of dental amalgams, giving special attention to autopsy studies. Until recently, there have been few published studies examining the relationship between dental amalgams and tissue mercury levels. Improved and highly sensitive tissue analysis techniques have made it possible to measure elements in the concentration range of parts per billion. The fact that mercury can be absorbed and reach toxic levels in humantissues makes any and all exposure to that element of scientific interest.
Dental amalgams have long been believed to be of little significance as contributors to the overall body burden of mercury, because the elemental form of mercury is rapidly consumed in the setting reaction of the restoration.Studies showing measurable elemental mercury vapor release from dental amalgams have raised renewed concern about amalgam safety.
Mercury vapor absorption occurs through the lungs, with about 80% of the inhaled vapor being absorbed by the lungs and rapidly entering the bloodstream. Following distribution by blood circulation, mercury can enter and remain in certain tissues for longer periods of time, since the half-life of excretion is prolonged. Two of the primary arget organs of concern are the central nervous system and kidneys.

Whole-body imaging of the distribution of mercury released from dental fillings into monkey tissues.Hahn LJ, Kloiber R, Leininger RW, Vimy MJ, Lorscheider FL.Department of Radiology, University of Calgary, Faculty of Medicine, Alberta,Canada.
The fate of mercury (Hg) released from dental "silver" amalgam tooth fillings into human mouth air is uncertain. A previous report about sheep revealed uptake routes and distribution of amalgam Hg among body tissues. The present investigation demonstrates the bodily distribution of amalgam Hg in a monkey whose dentition, diet, feeding regimen, and chewing pattern closely resemble those of humans.
When amalgam fillings, which normally contain 50% Hg, are made with a tracer of radioactive 203Hg and then placed into monkey teeth, the isotope appears in high concentration in various organs and tissues within 4wk. Whole-body images of the monkey revealed that the highest levels of Hg werel ocated in the kidney, gastrointestinal tract, and jaw.

Mercury toxicity and dental amalgam.Wolff M, Osborne JW, Hanson AL.There is adequate evidence that dental amalgam restorations, during and after placement, results in the release of Hg into the patient's body. Whether the Hg released from amalgam is due to placement procedures, surface abrasion, orl ater corrosion breakdown, there is evidence that a low level Hg release continues for years.
****It is generally agreed that if amalgam was introduced today as a restorative material, they would never pass F.D.A. approval.****
With new and more accurate techniques of measuring Hg levels, especially in tissue and blood, additional studies are necessary to relate blood-Hg levels with dental amalgam restorations. Studies must relate existing restorations as well as the placement of new restorations to body-Hg levels.
It is possible that we have accepted a potentially dangerous material as being safe.

A case report cited an incident wherein four adults were acutely exposed to mercury vapor resulting from the smelting of dental amalgams (Taueg et al. 1991). Initial signs of toxicity included nausea, diarrhea, dyspnea, and chest pains. Despite chelation therapy, all four patients died 11 to 24 days after initial exposure. Mercury concentrations in the house were as high as 912 µg/m3 at or within 11 to 188 days after the exposure, and postmortem blood mercury levels ranged from 58 to 369 µg/L. Historically, the triad of increased excitability, tremors, and gingivitis has been recognized as characteristic for mercury poisoning (Goyer 1991).
Low-level chronic exposures to mercury may affect the peripheral nervous system resulting in polyneuropathies (reduced sensory and motor nerve function) and neuropsychological effects (visual alterations, sensory loss, stress) (ATSDR 1989); these effects correlate to tissue levels of 20 to 40 µg/g. Neuropsychological effects were also reported by Smith et al. (1970) for occupational exposure to mercury levels of > 0.1 mg/m3. Mercury concentrations below this value did not appear to cause observable effects. Kishi et al. (1993) reported that neurobehavioral and motor function effects persisted in ex-mercury miners more than 10 years after cessation of exposure. Mercury vapor from dental amalgams has been identified as a major source of exposure to inorganic mercury in the general population (WHO 1991). An average mercury dose from dental amalgams has been estimated to be only 4 to 5 µg (Halbach 1995).
1. Central nervous system and kidneys: Both the central nervous system and kidneys are affected by inorganic mercury. The toxic effects may occur with acute, subchronic, or chronic exposure depending on the exposure level and the resulting body burden of mercury. Animal data suggest that the renal effects may be immunologically mediated. The central nervous system, especially during prenatal and postnatal development, is the primary target organ for methyl mercury. 3.4.2.1. Primary Target Organ(s)1. Central nervous system and peripheral nervous system: The critical target organs for inhalation exposure to elemental mercury vapor are the central nervous system and the peripheral nervous system.
Elemental mercury is found in liquid form, which easily vaporizes at room temperature and is well absorbed through inhalation. Its lipid (fat)-soluble property allows for easy passage through the alveoli into the bloodstream and red blood cells. Once inhaled, elemental mercury is mostly converted to an inorganic divalent or mercuric form by catalase in the red blood cells. This inorganic form has similar properties to organic mercury. Small amounts of non-oxidized elemental mercury continue to persist and account for CNS toxicity. Elemental mercury, as a vapor, which escapes from fillings, penetrates the blood-brain-barrier and enters the CNS, where it's ionized and trapped, attributing to its significant toxic effects. It is not well absorbed by the GI tract and, when ingested, is only mildly toxic. Inorganic mercury is highly toxic and corrosive and is the most destructive form, but its destruction is limited to where it's located. It doesn't have the ability to move through tissues like other forms. It gains access orally or dermally and is absorbed at a rate of 10% of that ingested. It has a nonuniform mode of distribution, secondary to poor fat solubility, and accumulates mostly in the kidney, causing renal damage
Millions of U.S. citizens are being exposed to mercury levels that exceed established health standards. Occupational exposure to mercury is a hazard for dental personnel. The only defense for its use comes from the total support of organized dentistry. Science, in over 12,000 scientific studies, has not been able to determine one constructive purpose served by the presence of this toxic metal in the human body. No amount of exposure to mercury vapor can be considered harmless. Once it has leached from the dental fillings and infiltrated the body, mercury becomes a neurotoxin. Mercury is more neurotoxic than arsenic and far more neurotoxic than lead. Mercury has been used quite extensively by the medical profession in anti-fungal preparations, diuretics, antiseptics, brain scans (radioactive mercury), etc. Merthiolate and Mercurochrome, which were very common "first-aid" items in most households and are still used extensively in hospitals, contain mercury. Nerve endings in the peripheral nervous system constantly scan their environment, engulfing foreign particles and bringing them across the cell membrane for inspection. These substances may then travel all the way up from the foot to the spinal cord to be presented to the nerve cells there. As it travels up the axon, mercury destroys a substance called tubulin, used as insulation for neurofibrils in the microtubules, effectively destroying the nerves. Within 24 hours of injecting a minute dose of mercury into a muscle anywhere in the body of test animals, it is detectable in the spinal cord and brain. The mercury is also found in the kidneys, lungs, bloodstream, connective tissue, adrenals and other endocrine glands. In the brain, it tends to congregate in the hypothalamus, which regulates the autonomic nervous system, and in the limbic system, believed to be the seat of emotions. The most devastating effect of mercury in the nervous system is that it interferes with energy production inside each cell. Nerve cells are impaired in their ability to detoxify and nurture themselves. The cell becomes toxic and dies, or lives in a state of chronic malnutrition. It is common for heavy metals to migrate to and acumulate in nerve ganglia (nerve relay stations). As a heavy metal (which means heavier than water), mercury tends to accumulate in the lowest parts of the body, such as the floor of the mouth, the pelvic floor, and the feet. Pelvic symptoms, in both men and women, are very commonly caused by metal toxicity of the Frankenhauser's ganglion. This can account for premature ejaculaton and an enlarged prostate in men, and endometriosis, pelvic pain, and hormonal dysfunction in women. Neural therapy cleans up this area through the painless injection of the Frankenhauser's ganglion (just above the pubic bone) with a local anesthetic. This opens up most of the ionic channels in the cell wall; the cell is then able to excrete much of its toxic components. This spurs the body to dump large amounts of mercury into the urine.
A dentist can't legally throw amalgam material or extracted amalgam filled teeth in the trash, bury them in the ground, or put them in a landfill, but the ADA and the EPA say it's okay to put it in people's mouths. In 1976, the U.S. Congress requested that the FDA "classify" dental amalgam fillings. The Federal Register recorded another such request in 1980. Multiple requests have been made over the years, yet there is still no classification of dental amalgam. The FDA has steadily refused to classify amalgam. The government agencies have been defending the use of mercury. Consider for a moment the national consequences if mercury in fillings were reported to be dangerous. The offending parties (dentists, the ADA, dental manufacturers and distributors), if found guilty, would be liable.
Mercury Vapor
Silver mercury fillings are not stable. These fillings emit mercury vapor at a rate of 2.8 micrograms per cubic meter of air breathed in the resting state, and their emission rate accelerates dramatically (as high as 49 mgs) after minimal mechanical, chemical, and temperature stimulations. It is also very volatile. This means that "metallic" mercury gives off mercury vapor when agitated, compressed or exposed to increases in temperature. Mercury vapor--which is colorless, tasteless and odorless--if inhaled into the lungs, passes into your bloodstream for distribution to all body tissues. It is at this point that biotransformation begins. Some of the mercury vapor remains unchanged, and some of it is oxidized. (This means to remove a pair of hydrogen atoms and to combine with oxygen. Chemically it means the increase of a positive electrical charge and the decrease of the negative charge, which in effect ionizes the vapor). The unchanged portion exists dissolved in the blood lipids (fats). The toxic effects are produced by that portion that is oxidized into mercuric ions which occurs partly in the blood, partly in the tissues but mainly in the red blood cells. Several researchers, beginning with Jernelov in 1969, have demonstrated the microbial conversion or methylation of mercury by various microorganisms. This was demonstrated in the laboratory as well as inside the bodies of animals. In 1975, Edwards and McBride demonstrated the methylation of mercuric chloride in human feces. It was also in 1975 that Rowland, Grasso and Davies determined that most strains of staphylococci, streptococci, yeasts and escherichia coli found in the human intestine (these are bacteria and yeasts of different forms and shapes that are normally present in the human gut) were capable of methylating mercury. It was in 1983 that Heintze and his associates made the startling discovery that saliva can also methylate mercury being released from the amalgam fillings. Confirmation of the escape of mercury vapor and ions from amalgam dental fillings is provided by The World Health Organization (WHO) Environmental Health Criteria 118 document (EHC 118) on inorganic mercury. It clearly states that the largest estimated average daily intake and retention of mercury and mercury compounds in the general population, is from dental amalgams, not from food or air. Mercury vapor inhaled into the lungs is absorbed almost 100 percent and immediately passes into the bloodstream. It takes approximately four minutes before mercury is converted or oxidized into an ionic state from its elemental vapor state. While in its elemental form, mercury vapor is lipid (fat) soluble and readily passes through the blood-brain barrier or the placental membrane. It can also accumulate in other organs and tissues of the body. The estimated average daily intake of mercury from dental amalgams is 3.8 - 21 micrograms per day. Two-thirds of the body burden of mercury is derived from the mercury vapor released from amalgams. The static, unstimulated release of mercury vapor from amalgam fillings, which goes on 24 hours a day, 365 days a year, is a major contributor to total mercury body burden. Large amounts of mercury vapor are released during chewing. After only ten minutes of gum chewing, there is an average increase in mercury release of 15.6 times more than during the resting state in test subjects. That converts to a 1,560% increase in mercury release."The World Health Organization has calculated that the average human daily dose of mercury from various sources are: Dental amalgam = 3.0-17.0 mg/day (Hg vapor) Fish and Seafood = 2.3 mg/day (methylmercury) Other food = 0.3 mg/day(inorganic Hg) Air & Water = Negligible traces (NOTE mg = Micrograms)" (World Health Organization Figures, from Environmental Health Criteria 118: Inorganic Mercury, Geneva, 1991. These figures confirm Amalgam as #1 average source for Environmental Mercury exposure.)"You wouldn't take a leaky thermometer, put it in your mouth, and leave it there 24 hours a day, 365 days a year. Yet that's exactly what happens when an amalgam filling is installed in your mouth."--Dr Michael Ziff.Mercury Vapor AnalyzerThe <I style="mso-bidi-font-style: normal">Jerome 431-X Mercury Vapor Analyzer uses a patented gold film sensor for the detection and measurement of toxic mercury vapor in the air, including the air in your mouth. It is a portable hand-held unit, weighing only seven pounds that can easily be carried to locations where there is a concern about mercury. It is the same unit used for chemical toxicology testing by OSHA and the EPA to monitor industrial hygiene, mercury spill cleanups and mercury exclusion testing. It is also suitable for monitoring mercury concentrations in a dental office during a daily routine.The simple push-button operation allows users to measure mercury levels in just seconds. The detection range is from 0.000 to 0.999 mg/m3 Hg. The gold film sensor is inherently stable and selective to mercury, eliminating interference common to ultraviolet analyzers, such as water vapor and hydrocarbons. When the sample cycle is activated, the internal pump in the 431-X draws a precise volume of air over the sensor. Mercury in the sample is adsorbed and integrated by the sensor, registering it as proportional change in electrical resistance. The instrument computes the concentration of mercury in milligrams or nanograms per cubic meter, and displays the final result in the LCD readout.The 431-X includes features not available in older Jerome models. When attached to either a data logger or computer, the analyzer automatically regenerates the sensor when it becomes saturated and then resumes sampling. An improved film regeneration circuit makes the sensor last even longer. It can operate up to six hours on a fully charged nickel-cadmium battery.This analyzer can easily be used to measure mercury vapor concentration on a patient before and after chewing a piece of gum for 5 minutes. Chewing, or tooth grinding, increases the heat between teeth and, thus, enhances the release of mercury from amalgams.This is an insightful eye-opener for those skeptical dentists who still refute the possibility of mercury leaking out of dental amalgams and their own health and their patients’ health being in jeopardy by their refusal to acknowledge something that is clearly visible with this machine.Some reported measurements of dental patients’ oral mercury vapor have been twice the OSHA standard of 50 µg/cubic meters which would place them in violation of the OSHA standard based on an employee’s 8-hour work exposure for a 40-hour work period seven days a week. Once measurements are taken, you will realize that the most toxic spaces may not be at one of the EPA’s superfund sites, but simply right under your nose.
Mercury Ingestion
Mercury readily mixes with food and is swallowed with it. The body uptake from inorganic mercury, swallowed with saliva, can be as much as hundreds of micrograms per day for individuals with a large number of amalgam fillings. Urinary excretion is a common indicator of mercury toxicity, even though fecal excretion of mercury is twenty times greater than the corresponding urinary excretion. There is a statistical correlation between the mercury concentration in saliva and the number of amalgam fillings. The United States government has determined and ruled that the continual exposure to mercury from amalgam fillings is not without risk to patients. We are concerned over picograms and micrograms of mercury in apples and are looking the other way when milligrams, one million times more, are being implanted directly into a child's mouth. There is a phenomenon that occurs in the mouth that can contribute to the release of mercury, and is called corrosion. Corrosion is similar to "rust" and means that surface particles of the filling material are being chemically broken down and released into the oral cavity.
Mercury vapor is released when you chew or grind. Additionally, minute rusted particles of the amalgam are being abraded and taken up by your food or saliva and swallowed. Intestinal enzymes and bacteria both produce methylmercury, an even more toxic form than elemental mercury, may act upon these minute particles of mercury filling. Although several sources contributing to the domestic mercury concentrations have been identified, human wastes

I used to enjoy providing advice in my area of expertise in this forum. And the banter. Feedback from ortho advice has vanished - people ask - then cut and run. And the finger pointers - why bother.
My other interests that I post to (some usenet - good luck finding me there, and web-based) have none of this BS.

I enjoy the thought that someday a long time patient or a relative will google him and then ask themselves if they really want him near them.

I agree completely.
But I think its a function of the "quick world" in which we live. Many times, an orthodontic or a restorative dental problem requires a number of opinions and a number of discussions.
This takes perserverence.

>I used to enjoy providing advice in my area of expertise in this forum. And >the banter. Feedback from ortho advice has vanished - people ask - then cut >and run. And the finger pointers - why bother. Once a few choice filters are in place, SMD ain't so bad. Recent developments hold promise for this groups' future.
>My other interests that I post to (some usenet - good luck finding me there, >and web-based) have none of this BS. Of course there are groups without a 'troll' and a 'protagonist'. Most usenet mavens use different monikers in different groups. I consider it a standard. You wouldn't find me in other groups either unless you knew where to look and my nick for each particular group.

carabelli - 25 Feb 2005 06:08 GMT Why *some* dentists on SMD don't respond to Jan Drew
> 1. She is a "CarloHoskins" ing idiot > [quoted text clipped - 22 lines] > > carabelli carabelli - 18 Mar 2005 02:40 GMT Simple reason to ignore Jan Drew's posts...........
1. She is IMHO probably TMSFIE to learn how to post on usenet ( now she will want to know what usenet is)_
2. SMD is her personal dartboard.
3. It is a waste of time.
4. Did I mention it is a waste of time?
5. Responses encourage her to continue posting here and that, my friends, leaves the dentally uninformed easy prey for the charlatans out there who are ready to take your money, give you false hope, or worse.
6. In case you forgot, it is a fruitless endeavour and suprisingly a waste of your time. --------------- She has however, mastered the art of manipulating those who choose to respond on SMD. Why on earth do you continue? For a time, I did love giving her smartass responses that nailed her as the pompous loudmouth idiot that she is. It became pointless, as in fertilizing castor bean plants - she/he/it simply feeds on it.. I usually scroll past her posts anymore - (update - blocked - along with a few other idiots). I am starting to scroll past SMD in my newsreader more frequently also. As are other former posters...........

StovePipe - 20 Mar 2005 02:14 GMT > 1. She is IMHO probably TMSFIE to learn how to post on usenet ( now she > will want to know what usenet is)_ SHNMNBM can get off her a.s and go look it up.
I'm snipping the other reasons, as we know them quite well.
> I am starting to scroll past SMD in my newsreader more frequently also. As > are other former posters........... Now, THIS is the part which saddens me; that the quality regs feel they must leave because they're getting pissed off by a bunch of ......<......>. It is the same for any reasonable patients or curious browsers. I wouldn't have stopped in here a year ago if SHNMNBM's posts were the first ones I encountered. Unfortunantely, they are amoung the most numerous. It is as if there was a permanent demonstration by those ......<......> outside the gates, harassing any one who might want to come in. JME, you and you alone can help here....
On the positive side, I've noticed that there are almost no more reg dentists who answer SHNMNBM anymore apart from JME.
Myself, the first thing I do when downloading SMD messages is sort them alphabetically by author and then I delete SHNMNBM, all the other bullshit childish arguments, and then I re-sort by grouping threads by the time/date of each thread. If I see SHNMNBM, it's because SOMEBODY, in his infinite wisdom, has quoted SHNMNBM, for reasons known only to the powers that be.
> Best wishes > > carabelli - Jan, I will wake up tomorrow pretty much the same as today, you > will too, won't anybody in your family help??????????? Again, Dan, DON'T break your rule; not even once. I never joined the moratorium. I _do_ enforce it to the fullest extent, and so must we all. If there is some way to make Dan's and DrS's posts repeat automatically, I feel that should be done; three or four times per day.
