Risks of a root canal – cyst?

Posted by Dental News Team On March - 26 - 2010

Our topic in the next weeks is root canal treatment and its risks! (7/10)

Not doing clean work during root treatment (no coffer dam, unsterile instruments,….) means bacteria can still get into the inside of the tooth via the dentist! This pictures shows several teeth whose roots have been treated, the green arrows marking areas where bone is inflamed – and the patient hardly even noticed anything, aside from having a “stuffy” nose. The bacteria kept multiplying until they reached a critical mass. Now they have started to invade the bone via the side canals of the tooth and are causing an inflammation – known as osteomyelitis. This process can take days, months, years or even decades, depending on the amount and type of bacteria, the structure of the root canal, instruments and materials used, etc.
-

Only when a tooth is sealed off tightly can these problems be avoided! Well-sealed means that the filling compound is spread evenly right up to the tip of the root. Moreover, once root treatment has been completed, it is also a good idea to seal off the top of the tooth, e.g. using a ceramic inlay and/or a crown. A tooth which is properly treated can last a lifetime, and you can save yourself a lot of pain and lost time, and avoid getting implants or bridges!

Poor root treatment can lead to

  • chronic apical periodontitis

A reticular cyst is one common complication arising from badly performed root treatment. Inflammation of the bone stimulates the growth of residual tissue – and this eventually turns into a cyst.

Pain after a root canal – is that normal?

Posted by Dental News Team On March - 23 - 2010

Pain after a root canal – is that normal?

Our topic in the next weeks is root canal treatment and its risks! (4/10)
Even if root treatment is performed properly, you may still feel some pain.

The pain usually goes down after about three days, and you usually don’t even need pain medication. The pain is caused by a slight irritation of the bone around the tip of the root. Should the pain get worse and/or you need medication, then something might have gone wrong during treatment.

Some possible complications arising from root treatment are:

  • incomplete filling of all canals, usually due to not using a magnifying glas
  • incomplete filling of root canal, due to time limits or imprecise workcontamination of the root canal
  • system by additional bacteria, usually due to not using a coffer dam and/or using unsterile instruments
  • parts of an instrument breaking off inside a canal, which happens if instruments are not stored properly or simply used one too many times

Why is treatment performed on a root canal?

Posted by Dental News Team On March - 19 - 2010

Our topic in the next months is root canal treatment and its risks! (2/10)

Today we will talk about why it is necessary to perform treatment on a root canal:

  • The most common reason is a deep cavity.

Cavities are caused by bacteria, and once the bacteria have reached your dental nerve, you start to feel pain, and the dentist has to perform an operation on your root canal. As long as the cavity is still only in your enamel, the early stage of cavities (as shown by the blue arrow in the x-ray), then it can be treated without drilling. But once the cavity reaches the dentine, the dentist has to drill.

-

  • But the presence of cavities is not the only reason for treating a root canal. Physical damage, eg. caused by overheating during dental work, various chemicals used to make fillings, or paradontitis which has gone untreated for too long can also cause damage to the nerve, and then you also need treatment.

What is commonly called a “dental nerve“ is actually a network of blood vessels, lymph vessels, connective tissue and nerve tissue – a.k.a.the endodont.

Damage to the endodont causes an inflammation, which usually kills it. And just as meat begins to rot when it has been lying around on the kitchen table for too long, the endodont also begins to decay once it is dead.
If the dental nerve was killed by a cavity then you not only have the problem of decaying tissue, but also bacteria, which damage the surrounding bone.

This can be a painful process, or then again you may not feel a thing – the dentist refers to this as pulpitis followed by necrotic pulp.

If the endodont is destroyed it also damages the surrounding jaw bone – but this can be prevented by proper treatment!

Good dentist, bad dentist

Posted by Dental News Team On February - 22 - 2010

Wouldn’t you like to know whether your dentist is good or bad?

We assume you do, which is why this week we are going to tell you all about what to consider when looking for a dentist and how to find a good one.

As usual, we will provide you with an overview of this week’s main topic!

  1. Good dentist – the cost estimate
  2. Dentists and their teams
  3. Hygiene in the dentist’s office
  4. Explaining procedures
  5. Trouble-shooting

Good dentist – the cost estimate
First of all, does your dentist even bother giving you a cost estimate?
No? Then s/he has no idea what s/he is doing!

If yes, how is the estimate structures?
Did you get a thorough check-up before you got the estimate? You should know what has to be done in your case and what will only be performed to fill the dentist’s pockets. What are we going on about? Well, in order for the dentist to provide you with a good cost estimate, s/he needs to have a good idea of the current status of your teeth and mouth.

If s/he does not bother performing a check-up, then it is likely s/he will only do things that cost a lot, namely implants and crowns.

You can always tell good estimates from bad ones, because good estimates always provide detailed information, which is collected during a check-up (assuming, of course, that your mouth really needs an overhaul, not just one bridge or implant if your teeth and mouth are otherwise healthy, otherwise, what would be the point of collecting data!).

A good cost estimate includes:

  • An anamnesis (medical history) / Patient’s request
  • Findings
  • Diagnosis
  • Recommendations for therapy / Alternatives
  • Description of procedures as needed

This information lets the dentist know what you wish to be done, the condition of your teeth (periodontal status, photos, models of your teeth, …), anything and everything you’ll need to set up a treatment plan.
-

The cost estimate should consider all kinds of work, even work which is less lucrative to the dentist. This includes fillings, root canal treatment, operations such as removing wisdom teeth, etc.

-

But this is the kind of work which should usually be done first, before doing more complicated procedures – you should make sure the ground is in good shape before you start building houses on it (crowns, implants etc.).

-

Summing up, a simple cost estimate can and should tell you quite a lot!

  • If your dentist offers you any treatment without performing a thorough check-up first, then chances are that s/he is only going to do things which cost the most money!
  • If the cost estimate starts out with an extensive check-up, then you’re on the right path!
  • If a cost estimate begins with the least expensive types of treatment (renewed root treatment, removing wisdom teeth, periodontal work, …) with dentures (crowns, bridges) last on the list, then stick with that dentist!

More on this topic tomorrow, and by the end of the week you should be able to tell a good dentist from all others!

Differences in dental implants

Posted by Dental News Team On February - 4 - 2010

The good in your jaw, the bad in …?

Is there just one good implant system, or are all equally good?
Generally, it can be said that the systems currently on the market are by and large the same when it comes to effects on bone healing.
Although implant manufacturers advertise exceptional surfaces which supposedly speed up the healing process for bone, in practice and as shown by studies there is hardly any noticeable or proven difference. Depending on the quality of bone, dental implants take 0-3 months to heal completely, and even a little longer after operations involving bone reconstruction.
-
-
When it comes to quality, what matters is the design of implant crowns. The dental crown is not directly connected to the implant, but rests on an intermediate layer, called an abutment (the red arrow in the picture).
The abutment is usually set onto the implant and screwed into place. This connection has its weak points, however. Some companies, such as Astra or Ankylos opted for a conical connection – and they turned out to be right!
