A broken file in a tooth is one of the rare but important challenges in root canal treatment, which can be completely solved if properly managed. This usually happens during specialized dental denervation and the use of endo files, and it can make the continuation of the treatment more complicated. However, the presence of new tools, the skills of dentists and professional techniques have made this problem manageable. If this is a concern for you, don't miss the continuation of the article to get to know the causes, solutions and new treatment methods.

What exactly is a broken file in tooth extraction?

Endodontic files are metal and narrow tools that are used to clean, widen and shape the root canal in the process of denervation. Breakage of this instrument during treatment may occur due to the complexity of the canal anatomy, excessive pressure or fatigue of the instrument. In this case, a part of the file remains inside the canal, and depending on its position, the continuation of the treatment should be done more carefully.

Breaking the Elzema file does not mean the failure of the treatment, but it requires a specialized decision; Whether the broken file should be removed from the tooth, or it can be bypassed with special techniques.

Why file in root canal? Does it break?

Breaking the file in the tooth root canal is an unpleasant but predictable event. Several factors can be the cause of endo file breakage, the most important of which we will examine below.

Complex and curved anatomy of the root canal

Dental canals do not always have a straight path. In posterior teeth, especially molars, these canals may have sharp curves or lateral branches. The greater the curvature angle, the more pressure the file is under and the probability of its failure increases. In such cases, it is very important to choose the right file and use a rotary device with adjustable torque.

Repeated use of the file and metal fatigue

Each endodontic file has a certain lifespan. Excessive use of the file makes it prone to cyclic fatigue. Cyclic fatigue occurs when the file is repeatedly moved in the curved area of the channel and develops internal microcracks; Cracks that will lead to file failure. In re-nervation of a tooth where the canal has already been treated, this possibility is even higher.

Excessive pressure or incorrect technique

One of the common mistakes in root canal treatment is applying too much pressure when entering the file into the canal. This pressure can push the file against the canal wall and cause it to break. Also, not having an initial glide path (Glide Path) or continuous rotation of the file without reciprocating movement increases the risk of fracture.

File type and quality Endo

Hand and rotary files are different from each other in terms of material and design. Inexpensive or low-quality files made from weak steel have less resistance to twisting forces. Reputable brands usually produce files made of nickel-titanium (NiTi), which have more flexibility and higher resistance. Choosing the right file for the type of tooth, the curvature of the canal and the type of treatment is a key step in preventing failure.

Does the broken file remain in Is the tooth dangerous?

Breaking the file in the root canal does not always mean the failure of the treatment; But deciding on the continuation of the treatment path depends on the location of the fracture, the presence or absence of infection, and access to the broken file. In the following, the important points about the complications and how to manage this situation are reviewed.

The effect of the location of the broken file on the success of the treatment

The location of the broken file plays an important role in the treatment decision. If the file breaks in the coronal or mid-canal area, the dentist can remove it; But if the fracture is in the apical third of the canal, it is more difficult to access. In this situation, some experts prefer to leave the file in place and continue the treatment more carefully.

Risk of infection and root canal treatment failure

Complications of a broken file in the tooth usually occur when part of the canal is not properly cleaned and contamination remains. In this case, there is a risk of infection, apical lesion or even treatment failure. If the broken file is located in an area that prevents the complete cleaning and disinfection of the canal, the possibility of these complications increases.

When can the file be left in the canal?

In some cases, leaving the broken file in the tooth is a logical and safe decision; Especially if the file is completely stuck at the end of the channel and the channel path has already been well disinfected. This work is recommended when file removal poses a high risk of root perforation or weakening of the tooth structure. Of course, in this situation, periodic follow-ups and examination of the condition of the teeth with radiographs are mandatory.

File management and treatment methods Broken in tooth

Treatment of broken file can be quite successful depending on location, channel conditions and available equipment. Choosing the right method depends on the expertise of the dentist and the accurate assessment of the clinical situation.

Removing the broken file (Instrument Retrieval)

In many cases, removing the broken file from the tooth is done using specialized tools such as ultrasonic systems, surgical microscopes, and fine forceps. These tools allow the dentist to gently pull out the broken piece without damaging the dentin or perforating the root. This method is preferred when the file is located in the accessible area and the risk of damage to the root structure is low. In this method, using thin hand files, the dentist tries to go past the broken piece and continue cleaning and filling to the end of the canal. This technique is considered very effective and low-risk in cases where the file is stuck in the apical area and its removal is associated with danger.

Apicoectomy surgery (root end surgery)

If none of the above methods are effective and signs of infection or lesion remain, root end surgery (Apicoectomy) may be required. In this method, access to the tip of the root is made from the gum area and the file is removed from the end of the root. This technique is mostly used for teeth whose root treatment has failed and re-treatment of the tooth root through the canal is not possible.

When to see an endodontist (endodontist) visited?

All teeth are not equally complex and in some cases, more advanced skills and equipment are required for successful treatment. If you are faced with a broken file in the tooth, you may need to see an endodontist (root treatment specialist) to make the best treatment decision.

The difference between a general dentist and an endodontist

A general dentist can perform simple root canal treatments in many cases; But in situations like breaking the file in the root canal, complex canals or re-treatments, specialized skills are required. By using surgical microscopes, advanced files and micromechanical techniques, the endodontist can manage even the most complex cases with high success.

Since the price of root canal treatment may vary in specialized treatments, it is better to know about dental tariff and Discuss your treatment options. Choosing a dental clinic in East Tehran with a specialized team, modern tools and careful follow-up will play an important role in the success of the treatment.

FAQ about broken file in Tooth

How much does it cost to remove a broken file from a tooth?

The cost of this treatment depends on several factors, including the location of the broken file, its accessibility, the chosen treatment method (extraction, bypass or surgery) and the doctor's expertise.

Is it always necessary to remove the broken file?

No; In many cases, especially when the file is at the end of the channel and shows no signs of infection, it is not necessary to remove it. In this situation, the dentist can continue the treatment with techniques such as bypass and properly fill the canal.

Should the tooth with a broken file be extracted?

In most cases, breaking the file alone is not enough reason to extract the tooth. With proper management and the use of modern treatment methods, the tooth is preserved and continues its normal function. Only in very special situations where there is an uncontrolled infection and none of the treatment methods are effective, tooth extraction may be considered.

Conclusion
