In clinical work, when we receive a patient with tooth pain (especially night pain, spontaneous pain ), after detailed consultation, clinical examination and X-ray examination, we will tell the patient: Your tooth needs root canal treatment... The patient is often confused, why can't he fill the teeth directly?
Today we introduce what root canal treatment is in the form of combining pictures and texts.
First of all, you need to know what the root canal is?
canals are hollow tubes inside the teeth, which contain pulp tissue and blood vessels, etc. Because there are differences in the anatomical structure of each tooth, the number of root canals also varies from 1 to 5.
root canal treatment is the process of thoroughly cleaning the infected or even necrotic dental tissue through specific devices, preparing for root canal shaping, disinfection and sterilization through mechanical cleaning combined with chemical drugs, and then filling the root canal intact after inflammation is controlled. With root canal treatment, we can retain infected teeth in the mouth to the greatest extent, avoiding the possibility of removal.
What should be done for root canal treatment?
1 | Caries cause infection of the endodontic nerves, and acute and chronic endodontic inflammation. Root canal treatment is needed to clear the infected endodontic nerves, rinse and disinfect the root canal lumen to relieve it. Pain and control inflammation; |
2 | Tooth wear is particularly severe, or trauma, cracks appear on the surface of the teeth, causing chronic necrosis of the teeth, and the teeth will become black and brittle , root canal treatment is also needed to remove the necrotic pulp nerves; |
3 | When peri-root apical inflammation of the teeth, root canal treatment is also needed to remove the pulp Infections in the cavity can then promote the absorption of root apical inflammation; |
4 | For patients with severe periodontitis, retrograde infection of the pulp will also require root canal treatment. |
root canal treatment?
Step 1: Take an image to determine the specific condition of the affected tooth
Doctors need to take X-rays to determine the degree of tooth caries, whether the pipes inside the teeth are unobstructed, whether there is inflammation in the root tip, etc., which all determine whether the teeth can undergo root canal treatment, difficulty of treatment, prognosis, etc. The caries are shown in the figure above, and the bottom of the caries is already connected to the neural tube, indicating that root canal treatment is needed.
Step 2: Open pulp sealing medicine
After clarifying that the affected tooth is affected, the doctor will use a high-speed rotating tool - a dental turbine, commonly known as a mobile phone (this mobile phone is not the other mobile phone), remove the caries, enter the internal pipe of the tooth, place inactivator or disinfection and sterilization drugs, thereby achieving initial analgesic and anti-inflammatory effects. Whether to undergo local anesthesia for
will choose based on the patient's clinical symptoms and pulp vigor. If the recent pain is mainly spontaneous and nighttime pain, local anesthesia is likely to be required.
Step 3: Root canal preparation for rinsing and disinfection
After the second step of the pulp sealing medicine, the tooth nerve activity is lost, the pain is basically controlled, and the root canal preparation is entered. If the patient found that the dental nerve activity has been lost during the first visit, he did not need to go through the above sealing steps and directly enter the root canal preparation stage after marrow opening.
canal preparation usually takes a long time, especially for large teeth. It is necessary to completely find out the root canal where the teeth exist, accurately measure the length of each root canal, and use root canal preparation equipment to clean up neural tissue and infectious substances in the root canal. The purpose is to remove infected substances in the root canal as much as possible and place disinfectant drugs in the root canal further eliminate inflammation.
Step 4: Root canal filling
After the previous treatment, if the teeth no longer have pain, the clinical examination meets the indications for root canal filling and inflammation is controlled, then we have come to the last step of root canal treatment: root canal filling, and the root canal that was cleaned in the previous step is filled with special drugs and materials.
3 Before filling the root canal, the doctor will place the tooth glue tip in the root canal for a "test tip". The purpose is to confirm whether the working length is in place. If there is a difference, it can be adjusted in time before filling the root canal. After the root canal filling is completed, an X-ray will be taken to further confirm whether the filling is in place and compact.
Warm reminder
At this point, the root canal treatment part is over. The subsequent decision will be made based on the teeth condition whether it is to directly fill the resin (tooth filling) or do crown repair, and whether piling repair is required. Now that you know the general process of root canal treatment, you must ask your doctor for the repair method after root canal treatment.
