Root Canal Treatment

An Overview

 

A root canal (tooth root) is composed of nerve fibers and blood vessels; a pulpy matrix is filled between the tooth cavity that sometimes gets inflamed due to multiple reasons such as fracture or deep decay. With root treatment, elimination of inflammation and bacteria can be done to improve the health of buccal cavity.

Micro-Endodontics or the root canal treatment, is a comprehensive focus which is in practice nowadays.

Root canal treatment also includes root filling revisions, i.e., the renewed root filling in already root-treated teeth.


Who needs root canal treatment?

 

The most common symptoms that can indicate the need of a root canal problem are provided below.

 

  • Frequent appearance of pain, particularly in response to hold & cold stimulus

  • Swelling in the gums or inflammation in the tooth

  • Tenderness of the tooth i.e. feeling sensitivity on tapping the tooth

  • Bad taste or odor coming out from swollen gum

 

Some teeth seem to give little indication that there's a problem within their nerve space. But an experienced dentist can easily look for subtle hints that are an obvious sign that a problem likely exists.

In most cases, it will be necessary to first apply local anesthesia; the tooth will be anesthetized. As a result, the tooth is opened to the pulp chamber using a drill. The carious, infected substance or the pulp tissue is removed, an existing bleeding is breast-fed, and the tooth is dried. To keep away saliva and microorganisms from the surgical field in the further course, a special clamping rubber is suitable for screening (rubber dam). This is a rubber latex, which is fixed to the tooth with a clip and is clamped outside the oral cavity in a frame.


Step-by-step process of root Canal Treatment

 

A. Depth of the root canals electronically or radiographically.

Teeth can be individually different in size, and accordingly, the tooth roots are differently long. Depending on the tooth group, they reach differently into the jaw bone. The root canal filling should be approximately 0.5 to 1.5 millimeters in front of the root tip since the root canals usually have their narrowest point here.

 

Bacteria or root canal filling material should not reach beyond the tip of the root, as this can lead to painful tissue reactions. Therefore, the required length of the root canal filling (working length) is determined with a so-called measuring x-ray and electronic devices (Apex locators). In pregnancy, of course, no x-ray should be prepared. Here the electronic length determination (endometry with Apex locators) proves to be very helpful.

 

 

B. Clean, expand and form channels

Once the channel inputs are found, the channels are processed with root canal instruments to remove the infected tissue in the channels. This is done in several steps, for which you need differently thin instruments (up to 0.1 mm). Since the channels are usually very narrow and curved, these instruments must be very flexible and well-cut. They should not be too thick and stiff. Otherwise they will not follow the canal course and possibly damage or destroy the tooth roots.

 

C. Disinfect the canal system, dissolve residual tissue

The root canals are not only narrow and curved, but they also have different branches and lateral canals. As a result, many areas cannot be reached with mechanical instruments, which is why the root canal system is thoroughly rinsed after mechanical processing. Various rinsing agents are required to dissolve organic tissue residues, kill bacteria and remove residues of the tooth substance from the canal wall. After rinsing the root canals are dried with different paper tips.

 

D. Close the drainage system tightly

 

If there was pain or a swelling already before the treatment, after cleansing and disinfecting, an antimicrobial drug is first introduced into the root canal system in most cases. The tooth is closed with a provisional, easily removable material.

 

The root canal system must be tightly closed to prevent microorganisms from reaching the oral cavity through the tooth into the jaw bone. The material of the root canal filling must above all be biologically compatible; it should not trigger any defensive reactions of the tissue around the tooth or the jawbone. Also, it must seal well and must not be allowed to dissolve in the tissue fluid. If pain or a swelling continue after the treatment, the root canal filling must also be removed. Finally, it is necessary that the filling is also visible in the X-ray image and can be controlled.

 


What are the possible benefits of this treatment?

 

Saving the natural tooth with this form of treatment offers several advantages including:

 

  • Normal biting sensation and force

  • Effective chewing process

  • Natural appearance

  • Protection of teeth over excessive wear or strain
