Do We Really Need to Use CBCT More Frequently in Modern Dentistry?

Simple two-dimensional dental images still remain the foundation of oral diagnostics today. However, there are situations where those images are no longer enough for the dentist to clearly understand what is happening inside the bone structures. That is when CBCT scanning becomes important, offering a much more detailed view of the area being examined. In complex cases, this technology helps clinicians make safer and more precise decisions. Without it, treatment planning may rely too heavily on estimation. CBCT allows visualization from angles where conventional radiographs stop providing useful answers.

From the beginning, CBCT images show the exact position of teeth within the bone and their relationship with surrounding anatomical structures. Although far more detailed than traditional radiographs, this type of examination is not necessary for every patient who enters a dental office.

In my everyday clinical practice, I follow a fairly simple principle:

When a dentist cannot clearly understand anatomical relationships from a standard two-dimensional image, CBCT imaging should be considered. The reason is straightforward — a three-dimensional scan reveals details that ordinary X-rays cannot provide. Without that additional perspective, it may be difficult to determine the exact position of important structures. In such situations, CBCT becomes a valuable diagnostic aid.

The purpose of imaging is not to create a more sophisticated picture, but to improve diagnosis, increase treatment safety, and provide better control during procedures. The information gained from the scan is what truly makes the difference.

Implantology as the Most Common Indication

One of the most important applications of CBCT is implant treatment planning.

Three-dimensional imaging provides a clearer understanding of:

• bone width and volume,
• the proximity of the mandibular canal,
• the relationship to the maxillary sinus,
• anatomical irregularities and concavities.

These details help clinicians place implants more accurately and significantly reduce the risk of complications.

The Importance of CBCT in Endodontics

Sometimes conventional images are not sufficient to explain why a patient continues to experience symptoms after treatment. In these situations, CBCT can provide a much clearer picture of what is happening internally. Instead of uncertainty, dentists gain a detailed insight into why previous therapy may have failed.

CBCT is especially useful for detecting:

• untreated canals,
• vertical root fractures,
• resorptive defects,
• persistent infections,
• complex anatomical relationships.

Certain findings become visible only when viewed from different angles. Multi-plane imaging often reveals conditions that standard radiographs fail to detect.

Surgery and Impacted Teeth

In some cases, tooth roots are positioned extremely close to important nerves, making CBCT imaging essential for accurate evaluation. The scan provides a precise view of the tooth position within the bone. Compared to traditional radiography, three-dimensional imaging offers much better spatial understanding of the surgical area.

This contributes significantly to:

• safer surgical planning,
• reduced risk of complications,
• better communication with patients before surgery.

The Importance of Responsible Use

Despite its advantages, CBCT should always have a clear clinical justification. Modern dentistry requires using only the amount of radiation necessary to obtain reliable diagnostic information — no more than needed.

Before prescribing CBCT imaging, clinicians should consider several questions:

• Will the scan change the treatment plan?
• Will it improve procedural safety?
• Will it reduce diagnostic uncertainty?

If the answer is no, conventional two-dimensional imaging is often entirely sufficient.

Technology as Support for Clinical Judgment

CBCT itself means very little if it is not used appropriately. Its true value lies in providing a clearer understanding of anatomical structures and helping clinicians make more informed decisions before treatment begins.

When used carefully and in the right situations, three-dimensional imaging helps dentists better understand what is happening beneath the surface. Instead of relying on assumptions, every clinical step becomes more predictable and logical. Risks for patients are reduced, and treatment outcomes become easier to plan. CBCT may not always be necessary — but when properly indicated, it offers a clear clinical advantage.
