A root canal therapy is used for treating a decayed or an infected tooth. The procedure is performed when the pulp is damaged or the nerve connected to the tooth is infected. It involves the removal of the nerve and the pulp and cleaning the inside of the teeth.So, what is dental pulp?
The pulp is the soft area in the center of the tooth. The root canal travels from the root of the tooth to the pulp chamber containing connective tissues and blood vessels that nourish the teeth.Why should the pulp be removed?
When the pulp or the nerve tissue is damaged, bacteria start building up in the pulp chamber. This can causes a serious infection or abscess. An abscess is a pus-filled pocked formed at the end of tooth’s root. Apart from an abscess, a slightest infection in the root canal may also give rise to the following problems:
A deep decay, large filings or repeated dental procedures can cause irritation and inflammation of the pulp or the tooth nerve. Moreover, a crack or a chip in the tooth too can lead to pulp infection.When do you need a Root Canal Therapy?
You may have to undergo a root canal therapy if:
1. Tooth is opened and root canal cleaned and shaped.
2. Cleaned Root canal is filled with gutta percha.
3. A post supports your teeth if recommended by the endodontist.
4. A crown protects it after treatment.
A Root Canal Treatment can be a Multiple Sitting or A single Sitting appointment as recommended by your endodontist.Root canal Re-treatment:
When a root canal treatment fails, the first course of action that is usually taken is trying to re-do the root canal treatment. It is usually done by an Endodontist (root canal specialist) or an experienced general dentist. Failed root canal treatment The process is very similar to Root canal Treatment, the difference is that besides taking any remaining infected tissue out, the doctor has to take old filling material, any posts and crowns or any other obstacle in the pulp space out to be able to successfully disinfect and seal the area of the root canal.
After the root canal treatment is done your dentist will place a crown to protect the tooth against fractures.What is Apicoectomy/Microsurgery?
Your teeth are held in place by roots that extend into your jawbone. Front teeth
usually have one root. Other teeth, such as your premolars and molars, have two
or more roots. The tip of each root is called the apex.
An apicoectomy may be needed when an infection develops or persists after root canal treatment,or retreatment. During root canal treatment, the canals are cleaned, and inflamed or infected tissue is removed. Root canals are very complex, with many small branches off the main canal. Sometimes, even after root canal treatment, infected debris can remain in these branches and possibly prevent healing or cause re-infection later. In an apicoectomy, the root tip, or apex, is removed along with the infected tissue. A filling is then placed to seal the end of the root.
If a root canal becomes infected again after a root canal has been done,Your dentist can do an apicoectomy to fix the problem so the tooth doesn't need to be extracted. An apicoectomy is done only after a tooth has had at least one root canal procedure. An apicoectomy is sometimes called endodontic microsurgery because the procedure is done under an operating microscope.
The endodontist will cut and lift the gum away from the tooth so the root is easily
accessible. The infected tissue will be removed along with the last few millimeters
of the root tip.
To complete the apicoectomy, 3 to 4 millimeters of the tooth's canal are cleaned and sealed. The cleaning usually is done under a microscope using ultrasonic instruments. Use of a surgical microscope increases the chances for success because the light and magnification allow the endodontist to see the area better. Your endodontist then will take an X-ray of the area before suturing the tissue back in place.
Most apicoectomies take between 30 to 90 minutes, depending on the location of the tooth and the complexity of the root structure. Procedures on front teeth are generally the shortest. Those on lower molars generally take the longer.
Is an advanced method of performing a root canal treatment under a microscope.
One of the most revolutionary developments in the field of endodontics is the operating microscope, which provides extreme magnification. This makes it possible to identify and treat even minute structures and problem areas. Thus pain can be minimized and excellent long-term results achieved.
Magnification and fiber–optic illumination are invaluable tools that assistin performing the technical aspects of endodontic treatment.
