Endodontics under magnification

Restorative dentistry uses microscopic techniques, and top-class endodontic treatment (root canal therapy) is completed with high-quality tooth reconstruction. As a result, the tooth regains its anatomically perfect shape and original biting and chewing function by reconstructing its cusps.

What is endodontics?

Endodontics is commonly understood as root canal treatment. Although this method is often associated with pain and traumatic experiences, it remains one of the most frequently used procedures for treating teeth in poor condition.

However, endodontics covers a much broader scope. As a field of science, it focuses on studying the dental pulp, and in practice, it involves treating it in various ways. It is an extremely effective method. In everyday language, endodontics is often simply referred to as “root canal treatment.”

Why is it worth treating teeth with root canal therapy?

Teeth help us bite, cut, and chew food—they need to be strong and durable. However, for them to function properly, they must also be properly innervated. Inside every healthy tooth is the dental pulp, a network of nerve connections.

Toothache is the body’s way of signaling that something is wrong and that intervention is needed. Problems with the dental pulp are most often caused by microorganisms that enter the inner part of the tooth. Inflammation not only damages the pulp but can also negatively affect the tooth itself and the surrounding bone structure.

That’s why root canal treatment is essential—it removes the source of infection, relieves pain, and helps preserve the natural tooth for many more years.

How does endodontic treatment work?

In cases of inflammation, root canal treatment is most commonly used. In simple terms, it involves removing the infected or damaged dental pulp through an opening made in the tooth. By removing the diseased pulp, the tooth can often be saved.

Once the pulp is removed, the empty space inside the canals is carefully cleaned, shaped, and then filled with a specialized material designed for such procedures. Microorganisms usually reach the dental pulp as a result of tooth damage—this can be due to trauma, cracks in the tooth structure, or more commonly, decay that exposes the inner layers to harmful bacteria.

Today, endodontic treatment is widely used and highly effective, thanks to advances in dental technology and techniques. It allows patients to preserve their natural teeth and avoid more invasive procedures like extractions and implants.

When is a microscope used?

Modern diagnostics in dentistry now rely on both radiology and microscopic examination to ensure the dentist can choose the most effective treatment approach from the very beginning. Performing a procedure without the support of advanced technologies can pose risks to the patient. During endodontic treatment, the tooth is opened, which exposes it to potential further infection. Therefore, using precise and safe methods is crucial to protect the patient’s health.

For dental professionals, microscope-assisted root canal treatment has become standard practice. However, for the patient, the stakes are high—their natural teeth are on the line. Modern microscopic endodontics makes it possible to save teeth that, in the past, would have been deemed irreparable and extracted in favor of prosthetic solutions.

A microscope in the hands of a skilled endodontist greatly increases the lifespan of a natural tooth, postponing or even eliminating the need for implants, bridges, or crowns.

1. Diagnosis
At this stage, an X-ray is taken to assess key features such as the number of roots (some teeth have up to four), their shape, width, and the path of the canals inside each root.

2. Cleaning of the tooth crown and infected canals
The crown of the tooth is cleaned of carious bacteria, and the tooth walls are prepared.
The cleaning of infected root canals is done in three steps:
a. Removal of the infected pulp from each canal;
b. Scraping bacteria from the canal walls using appropriate endodontic instruments;
c. Chemical disinfection to eliminate any bacteria that were not removed mechanically.

3. Filling the cleaned root canals
The empty, thoroughly cleaned root canals are filled with a special biocompatible material. This ensures a tight seal and provides effective protection against future bacterial infiltration.

4. Tooth restoration
The final (restorative) stage involves rebuilding the tooth. The goal is to restore its anatomical shape and functional role in the bite through:
a. filling (for small crown losses);
b. inlays or onlays (for larger defects);
c. prosthetic crowns (in cases of extensive damage).

FAQ

Does root canal treatment hurt?

Root canal treatment is typically performed under local anesthesia, which makes the procedure completely painless.

How long does root canal treatment take?

The duration of the treatment depends on the type of tooth, its structure, the number of roots, and the condition of the oral cavity. A single session may last from 1 to 1.5 hours. Typically, the entire treatment is completed over the course of two visits.

Why is root canal treatment so expensive?

The cost of root canal treatment is influenced by several important factors:

Advanced equipment is required: modern endodontic treatment relies on expensive tools such as magnifying loupes, a dental microscope, endometer, and endodontic micromotor.
Specialized instruments: the procedure involves the use of multiple precise titanium-nickel tools and files from reputable manufacturers.
Multiple X-rays: typically, around 3 radiographic images are needed during treatment.
High-quality chemical agents: a variety of chemical solutions are used to disinfect and ensure the long-term success of the treatment.

Does root canal treatment guarantee tooth preservation?

Root canal treatment is effective in about 90% of cases and ensures the tooth is preserved for many years. However, even with properly performed treatment, the dentist cannot give the patient a guarantee, as each body reacts differently.

What are the causes of failures?

Failures may be caused by:

1. The complex anatomy of the tooth and roots, such as curved roots, which prevent complete treatment procedures;
2. A weak response from the patient’s body;
3. Particularly aggressive bacterial flora within the roots;
4. Systemic infections.

Text (#71)

Isn’t it better to just remove the tooth?

Removing a tooth and later replacing the gap with a crown or implant is often a much better choice than keeping a “dead” tooth. Leaving the gap from a missing tooth unfilled will cause irreversible changes in the oral cavity within a few years.
