Minimising mercury vapour and dust production: Removing the Amalgam:
- We aim to ‘loosen’ and removed the filling intact, rather than drilling it away, in as few pieces as possible, a technique known as ‘chunking’. This entails:
- Detailed assessment from x-ray of what is ‘locking’ the filling in to assess how it can be most straightforwardly removed. Using a very fine sharp high speed bur (drill) we cut a channel around the outside of the filling and, if necessary section it into pieces, releasing it at the points identified and enabling it to be lifted out in ‘chunks’ – a new dental bur is used each time to ensure accurate cutting and easy removal.
Minimising dust and vapour absorption: Patient Protection:
- Clothes are covered with paper dental bibs
- Safety glasses are provided for eye protection
- Cotton wool rolls and gauze are placed
- Use of high volume suction and continual addition of water spray are supplied to the site where the amalgam is being removed
- The operators also protect themselves with a filtered mask, eye and face shields.
OPTIONAL ADDITIONAL PROTECTIVE ITEMS:
* These items can be provided, as wished, but due to the additional time per procedure and costs, will incur an additional charge of £75 without oxygen (OPT 1), £95 with oxygen (OPT 2) – You will need to let us know if you would like this incorporated into your treatment plan and estimate.*
- Clothes are covered with a plastic apron as well as paper dental bibs
- Dampened gauze is placed under the safety glasses to further protect the eyes;
- A cap for hair protection
- A RUBBER DAM (a rubber sheet that fits over the tooth) is customized to fit and isolate the filled tooth/teeth to prevent debris from contacting the oral mucosa;
- A sealer is used to seal around the edges of the rubber dam to prevent any ingress
- A paper liner is placed over the face under the dam
- ACTIVATED CHARCOAL is placed on dampened gauze underneath the dam – This helps to intercept particles and to chelate any dissolved metals that may seep under the dam.
(OPT 2): As above and also:
- Oxygen is supplied to the patient through a nasal mask.
Once the amalgam is removed completely:
- Once all mucosal tissues are fully inspected and cleaned, the mouth is flushed with copious amounts of water, again to ensure no ingestion or absorption of amalgam particulates.
- the oxygen and protective coverings are taken away
- an immediate inspection under the dental dam occurs. The gauze, cotton roll and activated charcoal/chlorella are wiped away. Gauze is then used to inspect the floor of the mouth and tongue to make sure no particulates seeped under the dam.
