When a patient with a treated tooth becomes symptomatic and shows radiolucency at one of the canals, what is the recommended treatment?

• A. Perform a root canal retreatment of the affected canal only
• B. Retreat all canals
• C. Extract the tooth
• D. Refer to an oral surgeon

Answer: (B)

When a patient with a previously treated tooth becomes symptomatic and shows radiolucency at one of the canals, it indicates potential complications such as persistent infection, inadequate sealing, or a missed canal. Retreatment of all canals is recommended because simply addressing the affected canal may not resolve the underlying issue if other canals are also harboring infection or if the initial treatment was inadequate across the entire tooth. By retreating all canals, there is a comprehensive approach to eliminate potential sources of infection and to ensure that all anatomical complexities of the tooth are properly addressed. This method increases the likelihood of a successful outcome by ensuring that any missed, under-filled, or over-filled areas are re-evaluated and treated appropriately, thereby promoting overall healing and reducing the risk of future symptoms. In this context, treating only the symptomatic canal might overlook additional issues present in other canals that could contribute to the ongoing symptoms. Additionally, extraction might not be necessary if there is a chance to salvage the tooth through appropriate retreatment, and referral to an oral surgeon is typically reserved for more complex cases or when surgical intervention is required, rather than for comprehensive retreatment of the root canals.
