Canal obturation

Also called root canal filling. This process is called Access Opening. During the second visit, the temporary filling material is removed and root canal material like gutta percha is placed. A temporary filling material is placed again. The apical limit of root canal instrumentation and obturation has been contested with most clinicians preferring to end biomechanical preparation at the apical constriction.

All endodontic materials including relatively inert gutta-percha can induce a foreign body-type reaction when extruded beyond the confines of the root canal system.

This article will provide an overview of the rationale behind taking a contemporary approach to obturation of the root canal system. It will outline a broad range of obturation materials including those traditionally used and newer, advanced ones that are now available that have active physical. Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy ) is a treatment sequence for the infected pulp of a tooth which in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Endodontic Obturation Systems and Filling Products Kerr Endodontics remains an industry leader in cutting edge endo obturation techniques and materials.

Our endodontic obturation systems are unmatched in quality and ease of use. We offer a complete line of advanced filling materials, sealers and equipment for all obturation techniques. In that publication, root canal obturation is defined and characterized as: The three-dimensional filling of the entire root canal system as close to the cementodentinal junction as possible.

The success of endodontic treatment is dependent on the obturation of the root canal with gutta-percha and sealers which can seal the entire root canal , thereby preventing microleakage and the reinfection of the root canal.

Over time, sealers and gutta-percha have become the standard approach to obturating root canals. The distal canal had a very unusual apical irregular shape as a result of extensive apical root resorption that had occurred. The mesial canals were obturated using a warm vertical compaction technique.

Several key features in the composition of MTA account for its bioactive and bioinductive properties when used as a canal filling cement. Obturation of the root canal system to the correct length and with no voids ensures enhanced success. The coronal seal also plays an integral part in this success. No system is superior to another and case selection may be important.

Proper root canal filling should achieve three dimensional obturation of the endodontics space to prevent micro organisms from entering and reinfecting the root canal system and to prevent tissue fluids from percolating back into the root canal system to provide a culture medium for any residual bacteria. The mandibular canal was directly inferior to the root apices of the posterior teeth of the time. The data also determined that as the mandibular height decrease the distance between the canal and root apices also decreased (21).

Enlarging the canal has a cleansing effect by way of removing the surface layer from its walls. This layer has often become impregnated with debris and contaminants. A wider canal can be irrigated more effectively (see next section). The newly designed Elements Obturation Unit incorporates advanced technologies involving software, metallurgy, electronics and industrial design with the best elements of System B and a patent-pending motorized extruder. From down-pack to backfill, from filling lateral canals to creating post spaces,.

He will then choose a master cone (the main gutta percha point) and insert it into your nicely tapered root canal. It should give the dentist a tug back feeling which indicates that the gutta percha point is fitted properly inside your root canal. Considered to be the two pillars of nonsurgical endodontics, canal preparation and obturation (filling) are often critical steps in the path toward long term tooth retention.

Depending on the diagnosis, endodontic treatment for a root canal will typically involve the preparation and obturation of the canal. Root canal obturation is a procedure that fills the root canal space with inert filling materials at the final stage of root canal treatment, after cleaning and shaping. The material used for root canal obturations is one of the critical determinants for the success or failure of endodontic treatment (12). Lately, a number of new endodontic materials have been introduced.

The quality of the endodontic obturation is usually evaluated using radiographic images upon completion. Additionally, during the root canal preparation and obturation phases of treatment, clinical criteria can be identified that are essential for achieving an adequate root canal obturation (8-10). Together, biochemical preparation, microbial control, and canal obturation form the basis for endodontic therapy. The advances in canal instrumentation technology have been extraordinary, improving NiTi rotary instrumentation in a way that even curved canals can be prepared for simplified debridement and shaping.

Generally, proper canal debridement does not require more than minimal canal enlargement, particularly if facilitated with good irrigation techniques. Step 9: Coat Cone with Cement Using the cotton pliers, remove a gutta percha cone from the package and cover it with an even coat of cement. Place the cone in the canal it to the working length, until tugback is elicited.

One of the fundamental goals of root canal therapy is removing contaminants from within the tooth. The barrier created by a dam aids with this goal by preventing saliva (a source of bacteria and debris) from gaining entry into the tooth while its work is being performed.
