What is obturation of the root canal?
What The Term “Obturation” Means in Endodontics. Dentists who perform fillings, root canal procedures, and other restorative methods of filling a tooth have to be skilled in obturation. Obturation is the technical term for a method of filling and sealing a tooth with root canal material.
What are the various techniques in root canal obturation?
Four basic techniques exist for the obtu- ration of the root canal system with gutta-percha and sealer (Figure 4): (1) the cold compaction of gutta-percha; (2) the compaction of heat-softened gutta-percha with cold instru- ments until it has cooled; (3) the compaction of gutta-percha that has been thermoplasticized.
What is done in obturation?
Obturation is described as the method used to fill and seal a cleaned root canal, using root canal filling material and sealers to complete a root canal procedure.
What are the criteria for obturation?
The radiographic criteria for evaluating obturation include the following categories: length, taper, density, GP and sealer removal to the facial cementoenamel junction in anterior teeth and to the canal orifice in posterior teeth, and an adequate provisional or definitive restoration (Fig. 9.12).
Why is obturation important?
Abstract. Root canal obturation is necessary when the pulp tissue is removed from the root canal system leaving a dead space that can be recolonized by microorganisms. After pulp removal, the root canal is cleaned, shaped, and irrigated after which it is obturated.
What does obturation mean in endodontics?
Endodontic obturation is the last but not least step of the root canal treatment. The sequential procedures during the rigorous treatment protocol are critical for a successful outcome in endodontics, starting from a correct diagnosis, access opening and cleaning and shaping of the root canal system.
What is the best obturation technique?
With respect to obturation, there are 3 techniques that are employed.
- Warm Vertical Condensation. This is the most commonly used technique in North America.
- Carrier-based techniques. This is a popular option used to fill canal spaces.
- Lateral condensation.
When do you obturate a canal?
Root canal obturation is necessary when the pulp tissue is removed from the root canal system leaving a dead space that can be recolonized by microorganisms. After pulp removal, the root canal is cleaned, shaped, and irrigated after which it is obturated.
Is obturation necessary?
Where should we stop obturation?
Therefore, summarizing and collating all this information, we come to the following conclusion: In order to obtain the highest endodontic success rate and least amount of postoperative complications, the obturation material should be placed anywhere between the constriction and the anatomic apex.
What is single cone obturation?
The single-cone technique comprises the use of a single gutta-percha point at environment temperature, with a variable cement thickness depending on the adaptation of the point to the root canal walls 2.
What are the different techniques of obturation?
the various techniques used these days for filling internal resorption include warm condensation, vertical condensation, core techniques, thermoplasticized gutta-percha, warm vertical compaction, and cold lateral condensation.
What material is used in a root canal?
What Is Gutta-Percha? Gutta-percha is a material used to fill a tooth after a root canal procedure. Gutta-percha, a plastic substance from a Malaysian tree called a percha tree, is used as a permanent filling in root canals.
What if obturation is short?
Short Obturation usually does not pose any problem until an unless -cleaning of the canal is not done properly. -pulp is still remaining. -sign of active infection. All of these and many more things require the tooth to be obturated again properly.
What is sealer obturation?
A sealer-based obturation with calcium silicate sealers could be a possible alternative to a continuous wave of condensation technique with a resin-based sealer. Sealer extrusion and postoperative pain negatively affect outcome of root canal treatment.
What is Bioceramic sealer?
Bioceramic sealers are sealers those contain calcium silicate and/or calcium phosphate as their main compositions, i.e., Endosequence BC Sealer while Hybrid bioceramic sealers are resin-based root canal sealers or other root canal sealers those contain some bioceramic components, i.e., MTA Fillapex.
What filling is used in root canal?
Gutta-percha is a material used to fill a tooth after a root canal procedure. Gutta-percha, a plastic substance from a Malaysian tree called a percha tree, is used as a permanent filling in root canals.
What is BC sealer?
EndoSequence BC Sealer is a patented, revolutionary premixed root canal sealer which utilizes new bioceramic nanotechnology. Unlike conventional base/catalyst sealers, BC Sealer utilizes the moisture naturally present in the dentinal tubules to initiate its setting reaction.
What is root canal obturation?
After pulp removal, the root canal is cleaned, shaped, and irrigated after which it is obturated. For successful root canal obturation, the materials need to have specific properties, and the clinical procedures undertaken are complementary to the materials used.
Why do I need multiple obturation techniques for one canal?
Obturation techniques may have to be modified to meet the needs of an individual case. Multiple techniques are often required to properly obturate a single canal because anatomic challenges dictate the need to practice problem solving during this phase of treatment. Most important may be the fact that no one technique can manage all cases.
What is an obturation dentist?
Dentists who perform fillings, root canal procedures, and other restorative methods of filling a tooth have to be skilled in obturation. Obturation is the technical term for a method of filling and sealing a tooth with root canal material.
Why is a sealer used during root canal obturation?
The use of a sealer during root canal obturation is essential and enhances the possible attainment of an impervious seal and serves as filler for canal irregularities and minor discrepancies between the root canal wall and gutta-percha.
