is there any special material which used under deep fillings, adapt to nervs.?

Question

Long time ago, my dentist cleaned the cavity in may toth and He said cavity is too deep also it has a crack to nerves, he should use a material which compatible with nerves, and give a less uncomfort. And also nerves may retract by time. it's %50 chance. its done and worked. What is the name of that material? anybody know?

this was10yrs ago in another country. No way to find the dentist. he puted a liner and filled directly with coposite without any temp filler. He said a chance but it worked perfectly. I didn't feel any discomfort or pain after filling. Maybe I remember "crack" word wrong but it was very close to nerves because I was tolerate only one sec touch. ( I didn't let for anesthesia).
I asked this question because I have same problem again for another tooth. This time dentist said he couldn't clean well because its close to nerves also he can see nerves as red spot so he putted some antibactrial thing maybe it can be stop decay. and than filled with temp. for 3 week test. My curiosity is this antibacterial thing and that nerv friendly liner are same? and also I'm woried that he didn't want to close to nerves so tooth hasn't cleaned well because this time i didn't feel serious pain ( this time no anesthesia too).
Now pain and discomfortness are decreasing but its sensitive against cold

Answer 1

The thing that is used most often when the decay is very close to the nerve is a paste of calcium hydroxide in a methyl-cellulose base. Brand names are Dycal or Life and others. Dycal is almost a universal name.

There are also several "glass ionomer" cavity liners, but I'd bet it was calcium hydroxide.

The procedure you have described is called a "sedative filling." I would bet (once again) that Dycal or similar calcium hydroxide liner was placed near the pink part and then a material called "IRM" (interim restorative material - clever) was placed over that. IRM is a reinforced zinc oxide with eugenol material. This is standard procedure in very deep cavities.

Answer 2

I don't understand "why" you want to know the name of the material if it's worked so well. I would assume that he used a sedative material to soothe the pulp chamber if he was close to an exposure or could visually see a nerve. There are plenty of different liners that "could be used" but most likely a small amount of IRM was used for a pulp cap. This is also used as a temporary sedative restoration. If you really want to know I'm sure it's recorded in your chart at the dentist office, call and check.


Additional information: More than likely it was the same procedure and basically the same type of material used before. Anytime decay is excavated and the nerve is very close or nearly exposed, the tooth has a high probability of abscessing and dying. Sometimes before we can clean it out, too much bacteria from the decay has reached the pulp or nerve by way of the dentin tubules causing the tooth to slowly die. There are various liners that can be used when a nerve is visible, dycal or IRM are two well known ones, dycal has been used as a liner for years and IRM is known for it's sedative effects. After placing either or both of these as liners he placed the restoration with no problems. If the pain decreases the tooth may recover and not need anything more than a restoration placed at a later date. If the pain increases, then you will need to proceed with a root canal therapy. Then I would be more inclined to believe that this tooth has had too much bacteria reach the nerve, and it's dying no matter what is done. Discuss this with your dentist, if your symptoms change, and if he hasn't placed you on an antibiotic then it would be advisable to do so to keep the tooth from abscessing further causing you extreme pain. So if the situation changes or the pain increases, you will need to have a root canal procedure on this tooth and follow this with a crown and build up to reinforce the stability of the tooth structure. Don't let taking the antibiotics at that time, make you think that the tooth has "healed" it will have only slowed the abscess or will be keeping it from increasing temporarily. Once you stop the medication, the abscess will form again, usually within days or weeks. Good luck and hopefully the tooth will continue to feel better. Trust your dentist, it looks like he's doing everything possible to try to save your tooth.

Answer 3

I'm a Dental Assistant, and you have me so confused. I think you have your info mixed up, and you misunderstood something he was telling you.

There are liners in which can be placed in the tooth, before they are filled..that is true. BUT, 'crack to nerves' is throwing me off. Are you meaning, 'crack in ROOT'? You cant have cracks in nerves, BUT you can have a cracked tooth and/or a cracked root, which is where the nerves are located.

A cracked TOOTH (depends on how and where its cracked)... will need to be crowned eventually. Minor cracks can be fixed by fillings.

A cracked ROOT... you need to have the tooth removed. You'll have problems down the road later on.

As far as liners are concerned.. they insulate (more or less) the inside of the tooth. So its less sensitive. A very common 'liner' that is placed inside teeth, is called 'Dycal'. As i said, it protects (insulates) from the tooth 'hopefully' from becoming sensitive. There are other liners though... Dycal is just a popular choice among Dentist.

Answer 4

THIS MAY HAVE BEEN ANY NUMBER OF LINERS UNDER THE FILLING THAT COULD HAVE BEEN USED. IF THIS WORKED WELL, GREAT!
THERE IS NO DEFINITIVE ANSWER TO YOUR QUESTION THAT ANYONE HERE CAN GIVE.
I RECOMMEND THAT YOU CALL AND ASK HIM DIRECTLY WHAT HE USED.

Answer 5

We use Durelon as a pulp cap. That is actually a cement, but studies on its use have shown great success.

Answer 6

the answer is CAVIT. It is a temporary filling material.
