How to perform pulp drainage for dental caries?
Pulpotomy and drainage for caries involve a treatment method for acute pulpitis or apical periodontitis caused by infected dental nerves. Teeth are composed of enamel, dentin, cementum, and pulp tissue. The pulp tissue, also known as the dental nerve, is located within the innermost part of the tooth, surrounded by the hard layers of dentin and cementum. Therefore, once the dental nerve becomes inflamed, the pressure within the pulp chamber rapidly increases. To alleviate the pain, it is necessary to release this pressure, namely by performing a pulpotomy and drainage. This can be done by drilling to remove some of the infected dental tissues, and then opening up the pulp chamber to relieve the pressure, significantly reducing the pain. If the dental nerve is completely purulent and necrotic, the top of the pulp chamber can be removed, followed by thorough pulpotomy and drainage.
What are the symptoms of pulpitis?
Pulpitis is a painful condition that occurs due to bacterial infection of the dental pulp tissue. Pulpitis has its own typical symptoms, including pain triggered by temperature changes. Eating foods that are cold, hot, sour, or sweet can cause severe pain in the dental nerves. Additionally, temperature stimuli intensify the pain; both cold and hot water can cause tooth pain. During the acute suppurative phase, there is pain with heat and relief with cold, meaning drinking hot water causes pain, whereas drinking cold water can alleviate it. Another typical characteristic of pulpitis includes nighttime pain; often there is less pain during the day, but at night or after falling asleep, the pain can awaken the individual from sleep.
Can a tooth with pulpitis be extracted?
Pulpitis cannot be treated by tooth extraction. Initially, pulpitis involves an inflammatory response in the pulp tissue. Extracting the tooth at this stage can cause the inflammation to spread throughout the body and, in severe cases, can lead to sepsis. Therefore, it is absolutely necessary to avoid tooth extraction during a pulpitis attack. However, dental treatment can be performed during a pulpitis flare-up. Firstly, the acute pain in pulpitis is caused by increased pressure within the pulp. The primary method involves performing a pulpotomy to relieve this pressure. Once the pressure is alleviated, root canal medication can be applied, followed by root canal filling to complete the root canal treatment and preserve the tooth.
Can a cavity that exposes the dental pulp be filled?
Cavities that expose the dental pulp cannot be directly filled in one session. Treatment of the tooth must be carried out before filling. In the early stages of a cavity, only the hard tissue of the tooth is damaged. If the decayed part is removed promptly and the dental nerve is not exposed, the tooth can be directly filled in one session. However, if the cavity progresses to the point where the dental pulp, or nerve, is exposed, this requires a nerve removal procedure. After the nerve is killed, the root canal is sealed with medication, and following inflammation control, the root canal is filled. Only after root canal treatment can the tooth be filled. Otherwise, the inflammation may further develop into apical inflammation, or even lead to space infections causing facial swelling.
Do cavities have worms in them?
Cavities do not contain worms; they are caused by bacterial infections and are a type of infectious disease. Cavities are also known as dental caries, and many people mistakenly believe they are caused by worms chewing on the teeth, but this is not the case. Cavities occur when bacterial infections attack the hard tissues of the teeth, leading to destructive dental diseases. It is also a chronic infectious disease. Cavities are caused by bacterial factors, meaning bacteria are the initial factor in their development. Bacteria can use glucose to produce lactic acid, causing demineralization of the teeth and thus forming cavities. If one brushes their teeth and rinses their mouth immediately after eating to control dental plaque, the development of cavities can be controlled or slowed. If not controlled in time, cavities may further lead to pulpitis.
Can cavities spread to other teeth?
Cavities are a disease caused by bacterial infections of the hard tissues of the teeth, and they are infectious but not contagious. If cavities are not treated in a timely manner, the inflammation can further infect the dental nerves, causing nerve inflammation, and even lead to damage in the apical region of the tooth. Damage to the apical region of a tooth may also lead to damage in the apical region of adjacent teeth due to inflammation. This situation can spread to other teeth, but it is limited to the stage of apical inflammation. If it is just a simple cavity, where decay is confined to the crown area of a tooth, it will not spread to other teeth. Therefore, once a tooth decays, it is necessary to carry out dental filling treatment as soon as possible.
Does periodontitis require tooth extraction?
Whether tooth extraction is needed for periodontitis depends on the severity of the inflammation. If the periodontitis is not severe, with no absorption of the alveolar bone, and there is only simple inflammation of the gums, it typically manifests as gum bleeding or bleeding when brushing teeth. There can be dental soft plaque around the gums, or dental plaque irritates and causes the gums to become red, swollen, and pus may ooze. In this case, scaling can be done to remove local irritants, followed by rinsing and medicating around the teeth. This can effectively control the progression of periodontitis and does not require tooth extraction. However, if it causes absorption of the alveolar bone and significant loosening of the teeth, tooth extraction may be necessary.
Will tooth decay recur after a filling?
Cavities are a type of chronic, progressive destructive disease caused by bacterial infection of the hard tissues of the teeth. Normally, a cavity should not recur after being filled, but each dental filling material has a certain degree of microleakage. If glass ionomer materials are used, the microleakage is somewhat larger, and after filling, there might be tiny gaps between the edge of the filling material and the tooth, where bacteria can continue to infect, also known as secondary caries, necessitating timely refilling of the tooth. If resin-based materials are used, the microleakage is relatively smaller, and the likelihood of recurrence after the filling is smaller.
How is periodontitis treated at the dentist?
The treatment plan for periodontitis and caries requires first taking an X-ray to understand the severity of the periodontitis. If the periodontitis is not severe and is merely inflammation of the gum tissue, characterized by red, swollen gums, pus discharge, or bleeding, this situation can be addressed by dental cleaning to remove local irritants, followed by medicated rinsing around the gums to improve inflammation. If the periodontitis is more severe, involving absorption of the alveolar bone, then guided bone regeneration procedures are necessary. After basic treatment of the periodontitis, the teeth enter a maintenance phase, requiring regular follow-up visits.
What is pulpitis?
Pulpitis is also an inflammatory reaction occurring in the pulp tissue, caused by the further infection of bacteria when tooth decay is not timely halted, and it represents the natural conclusion of tooth decay. The dental tissues are divided into enamel, dentin, cementum, and pulp tissue, with the pulp tissue located on the innermost side, which is commonly referred to as the dental nerve. If the bacterial infection is not promptly halted in the early stages within the hard tissues of the tooth, that is, if the tooth is not filled in time, the bacteria then further infect the innermost pulp tissue, causing inflammation of the pulp tissue, which is clinically referred to as pulpitis. Pulpitis involves severe pain, necessitating prompt root canal treatment for the tooth.
