Steps of dental brace treatment

Root canal treatment, also known as endodontic treatment, is the most common surgical method for pulp necrosis or root infection in dentistry. The advantage of this method is that it can preserve the tooth. Of course, the operation is more complicated and requires multiple times to complete. For the patient, the pain will be greater. Other conditions suitable for this treatment include pulp leakage, apical periodontitis, etc.

Treatment steps

Step 1: Root canal preparation

Before root canal preparation, preoperative evaluation of root canal treatment, pulp chamber preparation and working length measurement are required, followed by the root canal preparation stage. There are two methods of root canal preparation, and different preparation methods are used depending on the instrument selected. When doing root canal preparation for endodontic treatment, it is important to emphasize that since the root canal system is very complex, no instrument or preparation method can reach the entire root canal system, so the combination of mechanical preparation and chemical preparation is very important.

Step 2: Root canal disinfection stage

During root canal treatment, experts recommend that teeth with vital pulp or infection limited to the coronal pulp can be treated with a one-time method, while others can be treated with root canal sealing medication.

Step 3: Root canal filling stage

During root canal treatment, when filling the root canal, it is important to grasp the timing of filling. Generally, filling can be performed when there are no subjective symptoms, no obvious percussion pain, no odor in the root canal, no exudation, and no symptoms of acute periodontitis. There is no need to wait until all symptoms disappear, nor does it necessarily have to wait for the fistula to heal completely. Repeated filling can easily cause greater irritation to the periapical region. As for filling methods, the cold gutta-percha lateral pressure method is still the mainstream, while the hot gutta-percha method is the future trend.

Indications

1. Pulpitis: The dental pulp becomes inflamed due to bacterial infection. The dental pulp is in a sealed pulp cavity and is generally not infected by bacteria. When the tooth has a hole due to caries and the hole is too deep, external bacteria will invade the pulp cavity and infect the pulp.

2. Apical periodontitis: After the dental pulp is infected by bacteria, the bacteria will invade the alveolar bone through the apical foramen, causing inflammation of the tissues around the root apex. As long as the infected pulp is removed, the apical inflammation will subside.

3. Exposed pulp: When a tooth is broken and the dental nerve is exposed, root canal treatment is generally required.
