Apical cyst

Hello Doctor, I would like to ask how to determine whether to perform an apicoectomy or a retreatment of the root canal.
My lower left second molar has had three posts placed during two root canal treatments, and now there is a cyst underneath.
I consulted with doctors, and they all suggested trying microsurgery first; if that doesn't work, I would need to extract the tooth.
However, I have heard that an apicoectomy might allow me to avoid disturbing the posts, thus minimizing the risk of losing the tooth.
I have been in pain for almost six months, and my lower left third molar is currently undergoing microsurgery, which has not yet been completed.
Now, my second molar is causing me severe pain.
The doctor said I cannot treat both teeth at the same time.
I rely on pain medication to get through each day.
I would appreciate your guidance on what the best course of action would be.
Thank you.

Hello: It is recommended to pursue conservative treatment.
Microscopic root canal therapy should be performed as planned, because if apicoectomy is performed hastily, there is a significant risk of the tooth becoming unstable due to the shortening of the root, ultimately leading to extraction.
You may ask the physician to adjust the dosage and duration of the pain medication to help manage the prolonged waiting period for treatment.

When faced with the decision between apex cyst surgery (apicoectomy) and root canal treatment, it's essential to consider several factors regarding your specific dental situation. The presence of a cyst at the root of your tooth indicates that there may be an infection or inflammation that has not resolved with previous treatments. Here’s a breakdown of the considerations involved in making this decision.

Understanding the Procedures
1. Root Canal Treatment (RCT): This procedure involves removing the infected or inflamed pulp from inside the tooth, cleaning the root canals, and then sealing them to prevent further infection. If your tooth has already undergone RCT and is still symptomatic, it may indicate that the infection has persisted or that there is a new issue, such as a cyst.

2. Apex Cyst Surgery (Apicoectomy): This surgical procedure is performed when a root canal treatment fails, and a cyst or infection remains at the root tip. During an apicoectomy, the dentist or oral surgeon removes the tip of the root along with the cyst, and then seals the end of the root. This procedure can often preserve the tooth and avoid extraction.

Factors to Consider
1. Extent of Infection: If the cyst is small and localized, an apicoectomy might be a viable option. However, if the infection is extensive or if the tooth structure is compromised, extraction may be necessary.

2. Previous Treatments: Since you mentioned that your second molar has already undergone root canal treatment and has been re-treated with posts, this may complicate the situation. If the tooth has been structurally weakened, it may not be able to withstand further procedures.

3. Symptoms: Persistent pain for six months is a significant indicator that the current treatment is not effective. If the pain is severe and affecting your quality of life, it may necessitate a more aggressive approach, such as surgery or extraction.

4. Consultation with Specialists: It is advisable to consult with an endodontist (a specialist in root canal treatment) who can provide a thorough evaluation of your tooth and the surrounding structures. They can assess the cyst's size, the condition of the tooth, and the likelihood of success with either procedure.

5. Risks and Benefits: An apicoectomy can potentially save your tooth and avoid the need for extraction, but it does carry risks, such as the possibility of further complications or the need for additional treatments. On the other hand, extraction may lead to the need for a dental implant or bridge, which involves additional procedures and costs.

Conclusion
In your case, since you are experiencing significant pain and have a history of unsuccessful root canal treatment, it is crucial to have a detailed discussion with your dentist or an endodontist about the best course of action. They may recommend starting with an apicoectomy to attempt to save the tooth. However, if the prognosis is poor or if the cyst is extensive, extraction may be the more prudent option.

Ultimately, the decision should be based on a comprehensive evaluation of your dental health, the condition of the affected teeth, and your personal preferences regarding treatment outcomes. It’s essential to weigh the risks and benefits of each option carefully and to seek a second opinion if you feel uncertain about the recommended treatment plan.
