What are cavities? The exact translation of the word "cavities" literally means "rotting teeth". This term designated the inflammatory disease of marrowy substances (osteomyelitis). Without serious etiological, morphological and clinical similarity of processes, this term names disease of firm tissues of teeth.
The tooth root canal is our subject. The tooth root canal is a complex object for treatment. First, it is inaccessible to the visual control, it is impossible to glance carefully to survey it. Second, the tooth root canal description is very much variable on the structure - they can deviate, form pockets or branch. Difficulties with their processing and sealing are connected with it. What is the reason of treatment? The basic purpose of treatment of the tooth root canal is restoration of function of a root, typical for a healthy tooth. If the root of a tooth is in good condition then it is possible to carry out restoration of the tooth.
The indications to endodontics (treatment of the channel) are both chronic pulpitis and all forms of a periodontitis. Contra-indications to treatment - defeat of a periodontium, impossibility of restoration of a tooth, impossibility of processing of the channel, vertical crisis of a tooth. In treatment of the channel, dentists allocate three basic stages: providing the access to the channel, removal of contents from the channel and preparation of the channel for sealing and sealing the channel by the inert material promoting strong hermetic sealing.
All stages of treatment of the channel of a tooth include anesthesia. Access to the channel is provided with correct preparation of carious cavities, removal of a root pulpar chambers and creation of an easy approach in channels for endodontics tools. Then the dentist removes the content from the channel - a pulp, products of disintegration, and the microorganism, struck dentine, defines working length of the channel and prepares it for sealing.
Exact definition of length of the channel is very important as it allows avoiding possible complications - postoperative pains and periapical complications. Working length of the channel is determined with the help of roentgen or the special device.
Correct sealing of the channel is the most important and responsible stage of treatment. The materials for sealing include hardening materials (cements and some pastes), not hardening and firm pastes. Each of these materials has pros and cons. The root vehicle should block the channel reliably, not irritate the periodontium, not be dissolved, to not collapse and have rentgenocontrast properties that allow defining efficiency of treatment.
In many respects, the choice of a material for filling the channel is determined by personal skills and preferences of the stomatologist. The pins are the least popular for the long period. The metal pins were used as strengthening designs. The guttapercha points are the most effective methods of treatment for a pulpitis, as this material meets the majority of requirements.
