Under obturation of root canal

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. Minimal amounts of root canal sealers , which have been demonstrated to be biologically compatible, are used in conjunction with the core-filling material to establish an adequate seal. In another study which assessed teeth with endodontic failures, of the cases exhibited poor quality obturation whereas of the teeth had some canals which were left untreated. Prevents reinfection through good sealing of the apical foramina.

Creates a favorable biologic environment for the process of tissue healing to take place.

Ideal root canal filling material requirments. It should provide hermetic seal. Failure to completely clean out the necrotic soft tissue of the pulp system may cause staining, and certain root canal materials (e.g. gutta percha and root canal sealer cements ) can also cause staining. Root canal treatment was performed under magnification using a dental operating microscope, RRECIPROC blue NiTi single file system, and the Calamus dual 3-D obturation system. An infected root canal can usually be retreate unless the root is cracked or the tooth has broken below the gum line.

In these cases, tooth extraction may be necessary. Cement or Air Forced Through the Root Tip. It’s possible to overfill a root canal with dental cement, causing a bit of the material to ooze out of the root tip.

One of the important aspect is the post obturation filling or restoration which is very important to make sure that the Root Canal treatment is successful preventing any leakage of oral cavity fluids into the root canal , which can lead to failure of RCT and re infection. Cones are prefabricated root canal filling materials of a given size and shape (taper).

Sealers are pastes and cements that are mixed and hardened by a chemical setting reaction after a given amount of time. Setting time varies between the various preparations, from minutes up to days. 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. The data were entered over a spreadsheet, and statistical analysis was performed using SPSS software version (IBM, Armonk, New York, United States).

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). Root canal -treated teeth with overextension of the root canal sealer or solid materials such as gutta-percha or silver points into the sinus may be the main aetiological factor for aspergillosis of the maxillary sinus in healthy patients.

Successful root canal therapy is dependent on many factors, based on decisions made by the clinician from start to finish of each case. Peter Mann says, “There are many dentists I’ve met who are great and efficient at performing root canals daily in their practices. Obturation in endodontics: Clearing up the controversy.

However, many more dentists shy away from performing root canals , refer out all molar cases, and don’t see the procedure as being profitable for their practices at all. I’m a general dentist, and root canals are one of the procedures I. 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. Standardized gutta-percha points correspond to the ISO sizing system with a taper.

The caveat to this statement is that the minor constriction (MC) of the apical foramen must be left in its original position and size to act as natural barrier to the extrusion of obturation material. A root canal sealer or cement is essential with any gutta-percha technique, just as an etching agent and bonding material are required when using resin-filling techniques. These products serve many functions, such as being a lubricant to facilitate obturation and adhesiveness to enhance the seal and stability of the root canal filling.

Inappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of.
