Are sugar-free gums really beneficial to your teeth? Nigerian Tribune
Chewing gum is a favourite of for many people. Many people enjoy chewing gum to take their mind off what they are doing. Some chew gum to relax, when feeling hungry or to freshening their breath. Today, there are different brands of chewing gum, from the sugar-free to those sweetened the old-fashioned way with sugar, artificial sweeteners like aspartame or with sugar alcohols such as sorbitol and xylitol.
But, experts have found that brands of gum containing sugar can cause tooth decay if these types of gum are chewed too often or are removed from the mouth too soon. In fact, studies have shown that if a person chews gum containing sugar, it should be chewed for at least 15 to 20 minutes. After this time, the sugar is gone, but the saliva is sufficiently stimulated to rinse out some of the sugar residue.
Although sugar-free gum is marketed as healthy alternatives to sugary products and may seem to indicate that it is more tooth-friendly, this is not automatically the case. A study review in the British Dental Journal (BDJ) found that sugar-free foods and drinks contain acidic additives that may cause dental problems by eroding the enamel on consumers’ teeth.
Ironically, sugar-free products have been linked to a host of health concerns, including increased risk of cancer, stroke, and heart attack. These risks usually come from sugar substitutes like aspartame. Aspartame does not cause decay, but it may cause cancer. Xylitol, which seems to come with fewer of these risks, and is, unlike aspartame, not a carcinogen, is less easily absorbed (so it doesn’t cause a blood sugar spike).
Sorbitol, also known as E420, can trigger severe weight loss, abdominal pain and diarrhea in some individuals. A report in the British Medical Journal highlights the cases of patients who lost up to a fifth of their bodyweight. The cause was eventually traced to excess intake of sorbitol - one was eating between 14 and 20 sticks of gum a day.
Unfortunately, the researchers suggested that, while xylitol might not cause tooth decay, it can still aid dental corrosion, causing a loss of enamel over time. It leaves the enamel sensitive, weak and prone to cavities. This is particularly true when the sugar-free product in question contains both xylitol and an acidic ingredient–like fruit flavouring.
However, studies also show that chewing sugar-free gum after meals and snacks can reduce the risk of dental decay by about 40 per cent, especially about 20 minutes after eating, when plaque acid attacks usually happen.
Nonetheless, Dr Olusola Ibiyemi, a consultant in Community Dentistry, College of Medicine, University of Ibadan, Oyo State stated that studies have shown that chewing gum, including sugar-less gum, can have an indirect positive effect on teeth. According to him, “the benefits of chewing sugar-less gum far outweigh the risks. However, the risk is also something that every individual should be mindful as well. For example, chronic gum chewers tend to have TMJ (temporomandibular joint) problems. Gum chewing may result in muscle fatigue and pain—especially if it is done frequently and/or for long periods of time.”
People have been chewing gum since the ancient Egyptians, Mayan Indians, and early American Indians chewed resin from trees. Not all of us appreciate chewing gum, especially when you have to watch or listen to someone constantly chew away. But are those people noisily chewing gum actually doing something that is good for them, such as preventing mouth odour?
“When you chew gums, it stimulates production of saliva and increases salivary flow. Saliva is a natural buffering agent which helps in cleaning the mouth as well as in ensuring that the mouth does not smell. Also, some people do not produce sufficient saliva. But by chewing gum, there is increased saliva production to help them wet their mouth. Individuals with dry mouth experience cracked lips; their mouths are susceptible to infection and the lining of their mouths to injuries,” stated Dr Ibiyemi.
On the other hand, he said chewing gum should be in moderation to ensure it does not cause any problem. He stated: ”When a person chews gum constantly, it can cause facial disfigurement, the person might have pains in the jaw, and structures within the jaw joint can be destroyed.”
Nonetheless, this study review entitled “Are sugar-free confections really beneficial for dental health?”, in the BDJ, concludes: “As the use of sorbitol and xylitol containing products increases, the public should be educated on the hidden risk of dental erosion due to acidic additives, as well as the adverse effects of gastric disturbance and osmotic diarrhea.
Especially in sugar-free products, these adverse effects may be more insidious because the public has blind confidence that they are oral health friendly.”
It adds: “Although the presence of acidic flavourings and preservatives in sugar-free products has received less attention, these additives may have adverse dental health effects, such as dental erosion. Furthermore, the term sugar-free may generate false security because people may automatically believe that sugar-free products are safe on teeth.”
Similarly, BDJ’s editor-in-chief writing in a commentary on the findings stated: “The review raises the question of what health-related claims made on behalf of products can be trusted. The claim might well mean what it says and be suitably backed-up by research evidence, but does it fully say what it means, or alternatively, what is it not saying?
Sugar-free may seem to indicate that a sweet or other product is tooth-friendly, but this is not automatically the case.”
According to him, “given sugar-free products’ role in erosion of dental enamel, and doubts over perceptions of them as helping users to consume fewer calories, the result is a minefield of confusion for the patient who is trying his or her very best to comply with healthy choices and a complex labyrinth of communication for the professional in attempting to convey practical advice.”

Olympus E-420 review
Full review at: www.cameralabs.com : A ten minute video tour around the very compact Olympus E-420 DSLR, by Gordon Laing, Editor of www.cameralabs ...
what is the difference between a Mercedes Benz E320 and a E 420?
I want to get a more luxurious ride than my subaru. I really like the Mercedes-Benz E series from the mid to late 90's. I've driven a few and love them, and am willing to bite the poor gas milage an 92 octane gas. But i can't seem to find differences between the E320 and the E420
The E320 is a 6 cylinder. Up to '97 it has an inline 6 engine and from the '98 model year, it has a V6 ( both 3.2 litre displacement )
The E420 is up to the '97 model year and it has a 4.2 litre V8. There was a new V8 introduced in 1998 with a slight bump in displacement. It became the E430
level 3 for me .. yay!!
is that it?
ALSO the 320 is rear view drive while the 4wd version also available.
The E420 has a V8 diesel engine, the engine capacity is 3996cc, the power of the car is 231kw. However the E420 only available in rear wheel drive only.
E class is a business like car or for business people and for those who want luxury.
Engine
A 430 engine is a 8 cylinder engine which is a very powerful engine which was introduce in it is a 4.15 liter engine and its from a 90's S class. But uses much more gas! A 320 is a very well known engine in Mercedes because they fixed some part back at Mercedes headquarters and the were still in production until 2007 summer. The 320 is less gas consuming and has enough power even though it is a V-6.

Bluetec, DaimlerChrysler's moniker for its advanced diesel exhaust after-treatment system, makes its world debut on the 2007 E320 Bluetec. So it's not just a car; it's the company's way to make the planet less stinky. And it quashes once and for all the outmoded prejudices the American motoring public holds toward diesel engines. Smoke? Gone. Noise? A memory. Sluggish acceleration? How does zero to 60 mph in 6.6 seconds grab you?
Perhaps to contrast with the car's eco-groovy nature, Mercedes chose hedonistic Las Vegas as the location to let us loose in its latest diesel wundercar. Several hundred miles later, we came away with a renewed appreciation for modern diesel engines.
45-state availability
Mercedes is touting the E320 Bluetec as the only diesel-equipped passenger car available as a 2007 model. Stricter EPA emissions standards, known as Bin 8, affect all 2007 models.
To meet Bin 8 standards, the 2007 Bluetec exhaust system consists of three specialized catalysts and a particulate filter that handles nearly every last trace of smoke. NOx, a persistent by-product of diesel combustion, is controlled by a NOx storage catalyst and an SCR catalyst. These four devices scrub the exhaust gases squeaky clean, allowing the Bluetec to be sold Bin 8-compliant.
That turns out to be 45 states. California, Maine, Massachusetts, New York and Vermont leave Bluetec out in the cold for 2007 due to their adoption of even more stringent Bin 5 standards that take effect in the rest of the U.S. in 2009.
Meeting Bin 5's tighter NOx limits requires the injection of a nontoxic solution commonly known as urea — "AdBlue" in Mercedes-speak — into the exhaust stream. A reservoir containing AdBlue will require periodic refilling, which Mercedes reps say will be performed during the car's normal maintenance. Equipped with AdBlue injection, 50-state-legal Bluetec versions of the E-Class — as well as R-, ML- and GL-Classes — will be available as 2009 models.
In the U.S., the trigger for these high-tech diesels is Ultra Low-Sulfur Diesel (ULSD), which is much more catalyst-friendly than non-ULSD fuel. Bluetecs require ULSD, but that won't be much of a problem. ULSD is already widespread in Europe, and the EPA mandated that it be available in 80 percent of U.S. retail outlets by October 15 of this year. Bluetecs started trickling into dealer lots immediately thereafter.
Diesel dichotomy
Replacing the inline 3.2-liter diesel in the outgoing E320 CDI, the E320 Bluetec employs an aluminum-block DOHC 3.0-liter diesel V6. It's also the same basic engine used in the 2007 GL320 CDI and ML320 CDI. This mill is already available in non-U.S. markets in 13 different Mercedes and Chrysler models, including the 300C and Jeep Grand Cherokee and Commander.
Due to packaging considerations, this engine has an unusual 72-degree "V" angle, so a counterrotating balance shaft is employed to smooth out the power delivery. This is one refined, smooth engine, and most people wouldn't even realize it was a diesel if they weren't told.
Generating 208 horsepower at 3,800 rpm, this diesel gives up 60 hp to the gasoline-powered E350, but that only tells part of the story. Remember, this is a diesel, so it's got heaps of torque. Oh, Lordy, the torque. Thanks to an advanced fuel system and a Garrett GT20V variable-geometry turbocharger, the Bluetec belts out 388 pound-feet of torque from 1,600-2,400 rpm. That's a whopping 130 lb-ft more than the E350, and it makes its presence known when you plant your right foot.
From a standstill, there's only a brief soft spot in the power delivery before the turbo generates meaningful boost, followed by that beefy slab of torque that hauls the Bluetec forward with authority. Mercedes says it's only 0.1 second off the E350's sprint to 60 mph. Once underway, the always smooth corporate seven-speed auto does a fine job of keeping the Bluetec in the meaty part of its powerband. To account for the diesel's inherently lower-revving nature — redline is 4,600 rpm — engineers fitted the taller 2.65 final drive found in the E550 and E63 AMG.
With their gentler combustion characteristics, gasoline engines are typically quieter in operation than diesels. However, the Bluetec is so completely free of diesel clatter and turbo whistle that the only way to tell it doesn't burn gasoline is to note the glacial movement of the fuel gauge.
Easy on the Gatorade
The Bluetec carries a preliminary EPA rating of 26/37 city/hwy mpg, which beats out the E350's 19/26 by a huge margin and even out-economizes hybrids like the Lexus GS 450h. Base price for the Bluetec is $52,325 with destination, which is only $1,000 more than a similarly equipped E350. Factor in the Bluetec's fuel savings and this premium will be offset in about two and a half years at today's (low) fuel prices. Not bad, and when fuel prices climb, the investment pays off sooner. Sorry, wagon lovers — the 2007 E320 Bluetec will only be available in sedan guise, and 4Matic all-wheel drive will not be offered.
The comparison of the gasoline E350 to the diesel Bluetec draws similar parallels among hybrids, but with a startlingly different outcome. For example, the $55,615 hybrid Lexus GS 450h is rated at 25/28 city/hwy mpg. It shares its V6 engine with the $44,865 GS 350, rated at 21/29 mpg. Adjusted for differences in standard equipment, the hybrid commands a premium of $8,565 over the GS 350. But since the hybrid only saves $150 per year in fuel costs, it will take 57 years to recoup the purchase price difference. Use real-world fuel economy numbers, and a solely economic argument for opting for the hybrid gets even feebler.
This real-world value is part of the reason for Mercedes' big diesel push, although global markets also play into the equation. With penetration exceeding 60 percent in several countries, diesels have huge presence in Europe's passenger cars. Nevertheless, Mercedes' economies of scale reaped by commonizing hardware between European- and U.S.-bound vehicles allow diesel sticker shock to be minimized.
The right choice
For 2007, all E-Class models sport mildly tweaked styling. It's hard to spot the changes. Look closely and you'll find a deeper airdam and a new front bumper, resulting in a pointier nose and more pronounced intakes at the corners. The headlights, taillights and rear bumper are new, too. Overall, the look remains dignified, if generic from the rear. The only way to distinguish a Bluetec from an E350 (besides the badge, of course) is by its smaller wheels — the Bluetec rides on 16-inchers with 225/55 tires instead of 17s with 245s. As a result, the Bluetec wears 12.3-by-1.1-inch front brakes, the smallest of any E-Class model.
In some respects the 2007 Mercedes-Benz E320 Bluetec renders the company's E350 redundant. It offers a similar driving experience at a similar price, and in the bargain you get the Bluetec's bladder-busting 700-plus-mile range, and much better fuel economy. Neither one is a hard-core back-road burner, so if you've got a $50-grand craving for an E-Class and live in the right state, we say skip the E350 altogether in favor of the Bluetec. By nearly any measure, the Bluetec acquits itself as the entry-level E-Class of choice.
Where can i buy a Olympus Evolt E-420 in the ottawa region?
I know you can find it a future shop for 449.99, any where else cheaper? Oh and would this be a good DSLR for my first one?
I think it is a good DSLR. It's size is a real bonus. For a good, objective review have a look here, if you haven't already...
http://www.dpreview.com/reviews/olympuse420/
The E-520 seems to be more widely available. It may be slightly better value, however it is rather bigger than the E-420...
http://www.dpreview.com/reviews/olympusE520/
I don't know if you were planning to get any lenses along with the camera. This deal at Vistek for the E-520 with two lenses looks pretty attractive at $750. They don't appear to stock the E-420.

what is the difference between olympus e 510 and e 420?
I had zoomed in on E-510 but on comparison with e-420 I find no difference. They have a very good deal on e-420 on circuit city.
Can anybody tell me if E-510 is superior to E-420.
i checked on circuit city and it shows both have image stabilization
I am actually looking at the two same cameras. I feel that the E-510 is better with stabilisation built into the body , e420 doesn't have. also the pricing e-510 some cracking deals with 2 lens kit , whereas e420 , you get a basic lens and recommend you buy the pancake (though its good but expensive). go for the E-510.
How do I take panorama shots with my Olympus E-420?
help! i have an xd memory card already. i can take pictures in panorama mode, but i can't figure out how to blend them together.
Panoramas are stitched outside of the camera. You can use Olympus' software which will use images from your camera taken in panorama mode to create a panorama. I'm not sure what your camera does in panorama mode to make it so special.
If you want to create good panoramas, I suggest using something like Hugin. Hugin is free and does an excellent job of creating panoramas, even from crappy source material. Hugin is much better than some expensive stitching programs I've seen.
http://hugin.sourceforge.net/
Using Hugin, you don't need to take pictures in panorama mode.
The normal workflow is take images that overlap by at least 30%. This allows the program to correct lens distortion and vignetting. A tripod is handy, but not necessary. You'll want to pivot your camera at the entrance pupil of your lens which is somewhere along your lens barrel, not at the sensor plane, to minimize parallax error. Hugin uses enblend which is pretty smart about correcting parallax issues. You can use the tripod mount as the pivot point, but it won't be quite right, especially with close objects.
Best to shoot in manual mode, including focus. You want to keep exposures between shots all the same. Hugin will actually make decent panoramas from fully automatic settings, even if your exposures vary from image to image. You get better results if you shoot manual.
Bring the image set into Hugin. Hugin will create a beautiful pano with very little futzing about.
I don't know what the panorama mode in your camera is supposed to do but the correct way to shoot a panorama is to set your camera up on a tripod. Shoot your first picture. Then pan to the next part of the panorama overlapping the first shot. Continue until you cover the entire scene. Make sure you use the same exposure for all shots. A tripod is crucial because you need your horizon to be even. The software will correct any very minor differences but it wont work miracles.
Is an Olympus E-420 DLSR camera compatible with macro lenses?
Digital Zuiko 25mm f/2.8 prime lens' closest focus is 20cm. If you call that macro, then sure.
Do you think the Olympus E-420 is a good camera?
and why?
It's the smallest DSLR you can buy and that in itself is a good thing. Small has always been an Olympus speciality. Small wouldn't be so hot if it didn't work, but it does. I haven't used one myself but I usually look to dpreview.com for critical and well informed reviews. They gave it quite a favourable review and reading this would be a good starting point. You can also have a look at the reviews of other DSLRs on this site to make a comparison...

I really want a good starting profressional camera like the e420, Please tell me some pros/cons about this camera.
or another camera i should get instead, I'm a begginer for dslr's, but I know some stuff about cameras, and i want my price's worth.
i have read ..and was told by a few people ...they love it ....and it seems to be a good camera ....if your budget permits you ...go big ...but ...look it up on the internet ...read magazines on it ...look at flickr -com then you can see different pictures ...look at what they used for a camera ...stuff like that ...i know of one photographer ...a pro...he retired and got the one you want ...and he loves it ...so ya ..it must be good...i have all canon ...but its what i like ..thats all ...so look at all your options ...your budget ...what will you use it for ...then decide ...good luck
What is the best macro lens for an Olympus e-420?
Actually, Olympus makes two.
ZUIKO DIGITAL ED 50mm F2.0 Macro or ZUIKO DIGITAL
35mm F3.5 Macro
If you can budget for it, get the 50 mm f/2.0
Will the Olympus e-420 meter with m42 lenses?
Any actual owners of olympus e420/410 have experience with m42 or other kind of adaptor lenses?
You will have to use stop-down metering since there is no direct connection between the camera and lens.
