Abstract
Background: In medical practice, clinicians come across a lot of obstacle during a treatment , that can lead to a failure, like other dental treatments, endodontics too can fail. 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 the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. Purpose: Endodontic retreatment of a failure is required by the increased desire to preserve the tooth on the dental arch, preventing the need for dental extraction that may have adverse consequences in terms of functional and psychological effect on patients. Case: This article presents a case report about dental retreatment with 2 common failure, that was under filling obturation and non-fit post. Case management: The failure was corrected with endodontic retreatment, and finally restored with fiber post and porcelain fused to metal crown. Conclusion: Endodontic retreatment was done successfully on underfilling obturation and non-fit post. The patient was satisfied with the result.
Highlights
Endodontic retreatment is a procedure which is done on a tooth previously endodontically treated, but whose current condition requires further endodontic treatment to achieve a successful result
The usual factors which can be attributed to endodontic failure are Persistence of bacteria, Inadequate filling of the canal, Overextensions of root filling materials, Improper coronal seal, Untreated canals, Iatrogenic procedural errors such as poor access cavity design, Complications of instrumentation
The first and most indicated solution is represented by endodontic retreatment
Summary
Endodontic retreatment is a procedure which is done on a tooth previously endodontically treated, but whose current condition requires further endodontic treatment to achieve a successful result. A female patient, showed up in the dental office complaining of discomfort when eating in the right mandibular arch. She states that she got a wide range of allergic to drugs , including anasthesia and analgesic. The patient state that the restoration fail 3 month prior, and as seen it shown a metal post.The radiological exam showed us that, at the 4.5 tooth had been treated endodonticaly, but it shown under filling and failed post (Figure 1), but has no presence of periapical pathology
