Over obturation

Although periapical healing starts after Root canal cleaning, shaping and disinfection is done, it is an accepted scientific fact that good obturation is needed for it to stay healed over the years. Although a number of materials have been advocated over the last 1years for root canal obturation , gutta-percha has remained as the material of choice. However, its main disadvantages cited include lack of rigidity and. More importantly, obturation refers to the action of a soft metallic cartridge case being pressed outwards against the chamber walls by the high pressure of the internal gases. 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. For years, most schools and academic institutions taught that the gutta-percha point should end at the radiographic apex of the root—i. Unfortunately, many obturation overextensions occur because of a lack of deep shape or canal preparations that exhibit reverse apical one-third architecture.

This violates all four mechanical objectives of canal preparation and in obturation overextension with internal canal underfilling. This obturation left the root canal, not even under extension or over extension but it has extended into the adjacent tooth by extending through the inter dental bone. RootcanalOBTURATION DEEPTHI P. II YEAR MDS “Perhaps there is no technical operation in dentistry or surgery where so much depends on the conscientious adherence to high ideals as that of pulp canal filling.

This monograph will focus on measures that can prevent obturation mishaps which occur under the most vulnerable circumstances during the course of endodontic therapy.

Endodontic mishaps or procedural accidents are those unfortunate occurrences that happen during treatment. Recognition of such incidence is the first step in its management. Mishaps and serious complications in endodontic obturation ALAN H. How to use obturation in a sentence.

Obturation definition is - obstruction, closure. Historically, obturation has been considered one of the critical steps of root canal treatment an when not properly performe a potential cause of treatment failure. An early and often quoted report stated that most treatment failures could be attributed to inadequate obturation. The obturation was considered as over in case of beyond the apex. Over instrumentation and inability to provide a proper taper usually leads to overfill.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Over -Extension is Incomplete Seal and Filling Past. Under filled root canal ENDO-surgery seminar 2. Nouri Esmaeil Nouri Amin Esmaeili Morteza Razon Arlhie Presented by: 3. Speaker: Paul Vincent Abbott, B,D.

Run your master apical file, check patency and irrigate all over again. Since the success of a root canal is more dependent on what you take out as opposed to what you put in, make sure that you have sufficiently cleaned out all the canals and created a shape that will accept your obturation. It was always their belief that most problems with the grain jacket failures had to do with rough obduration of the base.

Gutta-percha has proven to be the material of choice worldwide for successful obturation when used in combination with a root canal sealer.

Gutta-percha points alone cannot completely seal the space between the dentinal walls, root canal irregularities, lateral and accessory canals and spaces between gutta-percha points used in lateral condensation. The radiographic success for over - and optimally filled canals, when combining both lentulo groups, was significantly greater than under-filled root canals (P=.009). Conclusions: There was no statistically significant difference between the techniques of obturation , according to the quality of the root canal filling or success rate.

Bladder Neck Contracture. A urethral stricture is a scar that causes narrowing at one or more points in the urethra or at the point where the urethra connects to the bladder (a bladder neck contracture). Surgical management of overfilled gutta -percha and root capping with mineral trioxide aggregate in a young patient.

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. Note also that the Thermafil technique can be used after canal preparation with conventional files used in a step-back technique.
