Root Canal Treatment and Fillings
The main purpose of dentistry is to keep the teeth in the mouth and maintain the patient's chewing function. The parts of the teeth seen in the mouth are called the crown and the remaining parts in the jaw bone are called the root. The crown parts of the teeth are surrounded by gums. Teeth consist of hard and soft tissues. The hard tissues in the crown part of the tooth are the enamel on the outer surface and the dentin tissue beneath it. The root part is covered with cement and dentin underneath. This hard tissue complex consisting of enamel, cementum and dentin; it surrounds a cavity composed of connective tissue with vessels and nerves. Pulp cavity in this space, located in the connective tissue is called pulp. Pulp is the tissue that is responsible for the development, feeding and defense of the tooth.
Pulp may be inflamed for various reasons or may be infected by the introduction of microorganisms. In this case, the pulp tissue must be removed and the duct cavity should be cleaned, shaped and filled with tissue-friendly duct fillers. These procedures are defined as channel treatment.
”Bacteria are the main factor in pulp diseases“. There are bacteria in the mouth of each person and they do not cause any damage under normal conditions. But some of them take out acid by metabolizing sugar or food or beverages containing sugar. These acids also damage the enamel and dentin. When the bruises formed in this way are left untreated, the bacteria progress to the pulp tissue under the dentine and cause inflammation.
Another factor that can damage the pulp is the trauma to the tooth. As a result of a violent impact on the tooth, blood circulation can be cut off and the pulp tissue loses its vitality. Chronic traumas to the teeth (high restorations, traumas due to tooth squeezing / squeaking) can cause inflammation or loss of pulp.
Another factor that threatens the pulp is the presence of untreated periodontal (gingival and surrounding) disease around the tooth. Bacteria can damage the pulp of the tooth from the tiny side channels opening to the root surface via the gingiva pocket.
What causes root canal treatment?
Repeated caries under deep decay, previously made fillings or crown prostheses (coatings),
The patient's complaints do not pass after filling or crowning of teeth,
Crowns / root fractures in the teeth as a result of the impact,
Damage of dental pulps due to non-function movements such as chewing habits or tooth grinding,
Pulp damage after advanced gum diseases or gingival operations,
Determining that pulp has lost its vitality.
In prosthetic restoration of perplexed teeth, channel treatment may be necessary.
It may also be necessary to treat the adjacent teeth with canal treatment during the removal of large cysts of wisdom teeth or in the jawbone.
What are the stages of canal treatment?
- Canal treatment is an operation that lasts an average of 1 hour. The stages in this process are as follows;
- Stimulation of the tooth and surrounding tissues by regional anesthesia,
- Isolation of the tooth from surrounding tissues,
- Preparation of endodontic cavity for access to root canals,
- Determination of working length in root canal,
- Reshaping root canal cavity,
- Cleaning and disinfecting the root canal cavity,
- Sealing of the root canals.
- In this process, at least 2 radiographs are taken from the tooth. In some cases this number may increase. In cases where the tooth has lost its viability, it is necessary to apply an antiseptic substance to the root canals after the tooth is shaped and cleaned during the treatment of the canal.
A tooth treated with root canal was removed; there is no pain in the teeth against external stimuli such as cold-hot. If there is pain or inflammation of the relevant tooth before the treatment, it is normal to experience mild pain in the first few days following the treatment, especially when chewing on the tooth.
The success rate of well-made canal treatments is around 90-95%. However, due to the patient's oral hygiene due to the formation of a new decay in the tooth or the formation of a fracture in the filling of the teeth, root canal inside the leakage of bacteria again in the case of; root canal infestation again.
After the canal treatment, aesthetic fillings or crown coatings can be made according to the loss of the tooth.
