If a patient has symptomatic radiolucency in one of the canals after a root canal, how should it be treated?

• A. Retreat the specific canal with radiolucency
• B. Retreat all the canals
• C. Perform a retrograde fill of the affected canal
• D. Extract the tooth

Answer: (B)

In cases where a patient presents with symptomatic radiolucency in one of the canals following a root canal treatment, retreating all the canals is viewed as a more comprehensive approach. This is because the presence of radiolucency often indicates persistent infection or inflammation within the root canal system. It may not solely be limited to the canal exhibiting the radiolucency; infection could be present in other canals that are not currently symptomatic but may lead to future issues if not adequately treated. Retreating all the canals allows the clinician to ensure that every part of the root canal system is properly cleaned, shaped, and obturated, reducing the risk of further complications. This thorough method also addresses any possible missed or under-treated canals, which can be a common source of failure in initial root canal treatments. While retreating the specific canal with radiolucency or performing a retrograde fill of that canal could be considered in certain situations, these options may not be sufficient, as they may leave other infected areas untreated. Extracting the tooth would generally be considered a last resort, typically reserved for instances where the tooth is non-restorable or if retreatment is unlikely to succeed due to other factors.
