European Commission study recommends ban of dental amalgam

BRUSSELS, Belgium: A new study, conducted on behalf of the European Commission, recommends phasing out dental amalgam use over the next few years owing to mercury’s negative impact on the environment. According to the recently published study results, the ban should be combined with improved enforcement of the EU waste legislation regarding dental amalgam.

Dental amalgam has been in use for over 150 years for the treatment of dental cavities and is still used by the majority of dentists. It is often felt that this is an ideal material because of its longevity but sometimes perhaps for the wrong reasons. There is an increased risk of fracturing the tooth with large amalgam fillings, as it is really just a metal block, which has been wedged into the teeth. The point here is that we are trying to save the teeth not the fillings.

Dental amalgam is a combination of different metals with about 50% mercury. It is estimated that many tens of tons of mercury are placed in people’s mouths through amalgam worldwide. It has been a controversial material ever since it was introduction due to its mercury content, and the controversy still rages both in the dental and in the public domain, resulting in a number of TV documentaries. Recent evidence that small amounts of mercury are continuously released from amalgam fillings has fuelled the controversy. According to Mutter (2011), dental amalgam is by far the main source of human total mercury body burden; this is proven by autopsy studies which found 2-12 times more mercury in body tissues of individuals with dental amalgam (results of autopsy studies are considered more valuable for examining the amalgam-caused mercury body burden than the analysis of mercury levels in urine and blood). Although there is some consensus on the fact that people with amalgam fillings are exposed to some mercury released from the amalgam, the magnitude of this exposure is subject to controversy.

HEALTH EFFECTS OF DENTAL AMALGAM
Dental AmalgamThe main direct exposure pathway to inorganic Hg (acute exposure) in individuals having dental amalgams occurs during the placement or removal of the amalgam. The release rate of mercury vapour is dependent on several parameters, including: filling size, tooth and surface placement, chewing, hot beverages, food texture, tooth grinding, and brushing teeth, as well as the surface area, composition, and age of the amalgam. Moreover, mercury from amalgam may be transformed into organic mercury compounds by microorganisms in the oral cavity and gastrointestinal tract.

Some scientists have observed that mercury concentrations in blood and urine do not adequately represent the mercury levels in body tissues. A number of experiments with animals and humans showed that despite normal or low mercury levels in blood, hair, and urine, high mercury levels were found in critical tissues like brain and kidney. For the living human being, who would rather not wait for the autopsy results, they can choose to undergo a Melisa test www.melisa.org. This is a blood test, which is carried out under very strict conditions to produce very accurate results.

We at Integrated Dentalcare have been a mercury-free clinic for the last 15 years. Over that period we have gained valuable experience in removing and replacing mercury fillings in a strict, controlled and safe environment which protects our clients as well as our team. This journey has been fueled by our personal desire to find safer and more biocompatible materials to reconstruct teeth. What we choose to put in people’s mouth may have an impact on that individual’s general health. After all the mouth is the opening into the rest of the body!

No pain, just dental gains

No pains, just dental gains

A DENTIST surgery in the Capital has launched what it calls the first pain-free treatment in Scotland. Integrated Dentalcare, based in the city centre, has brought in a technology used in Hollywood called water laser treatment.

It means the practice’s 1000-plus patients will be able to access the care, which completely numbs the tooth and the area around it, making it entirely painless.

Dental practitioner Neeraj Puri said: “We see water laser treatment as a fantastic way of taking the fear and discomfort out of going to the dentist. The treatment makes your tooth feel drowsy which allows us to work on it without any discomfort.

“We definitely believe it is worth the £60,000 investment we have made in it.”

Light Magic

Pain Free Dentistry

Laser Dentistry has many advantages, not least the absence of pain writes Jake Harris

Laser Love like interest free credit or a barbecue summer, pain-free dentistry sounds too good to be true. The last thing I expected when I popped in to investigate Integrated Dentalcare’s optimistic cliam was to be put in the dreaded hotseat myself to test out this laser procedure, new to Scotland.

Being that special grade of wuss who winces at removing a plaster I had my reservations, but Dr Neeraj Puri tackled these by scoring a tiny circle on my palm to prove its benign magic. (For even bigger children he turns this into a smiley face).

Okay, so far so good, but we all know how sensitive our teeth and gums are, but Neeraj wasted no time in getting down to business with my small filling. No anaesthetic and subsequent awkward small talk while your mouth swiftly bloats to rubber dinghy proportions. In goes the water gob hoover, and out comes the laser, like a tiny red blowtorch, held steady for around 90 seconds. The fear factor of that whining drill is banished, replaced by a less dramatic rhythmic clicking like the sound of a gas hob lighter. And so the job was done with no blood, no rinsing, no numbness and very little evidence that I’d even been to the dentist.

Here comes the science bit: the dentistry combines laser energy and water to provide gentler, more precise treatment that conserves healthy tooth structure, minimising pain and discomfort.

The laser reacts with water molecules to create a serrated effect, while releasing endorphins which actually raise your pain barrier.

Water laser treatment eliminates the heat and vibration which causes the discomfort you get from drilling, but it also sterilises as it cuts, leaving less chance for bacterial contamination.

The laser’s pinpoint accuracy enables the dentist to leave as much healthy tooth structure in place as possible, allowing you to keep your own teeth longer. Because of the precision involved, procedures that once took several appointments to complete, such as multiple fillings, can now be finished in a single visit.
