Benefits of oral ultrasound from diagnosis to treatment

In the modern world of dentistry and oral medicine, diagnosis no longer relies solely on visual examination or traditional X-rays. Ultrasound imaging has emerged as an advanced and effective tool for detecting a wide range of problems in the oral structures and surrounding tissues. This technique stands out for being safe, painless, and free from ionizing radiation, making it an ideal choice for adults, children, and even pregnant women.In this Dalily Medical guide, we’ll explore everything you need to know about ultrasound for oral structures — how it works, its uses, benefits, potential risks, and the latest advancements in the field.

What is Ultrasound Imaging for Oral Structures?

Ultrasound is a medical imaging technique that uses high-frequency sound waves to create images of internal organs and tissues. When used in dentistry, it helps evaluate salivary glands, muscles, soft tissues, lymph nodes, and even certain pathological lesions inside and around the mouth.

How Oral Ultrasound Works

• The device emits high-frequency sound waves through a probe.

• These waves bounce back after hitting different tissues, and the reflections are captured and transformed into images on a screen.

• The appearance of tissues varies according to their density and composition, allowing differentiation between various structures.

Advantages of Oral Ultrasound Imaging

• Completely safe – no ionizing radiation.

• Painless – no surgical intervention required.

• Instant results – images appear in real-time during the scan.

• High accuracy – especially for soft tissue evaluation.

• Suitable for sensitive cases – such as pregnant women and children.

Uses of Ultrasound in Oral Structures

1. Salivary Gland Evaluation

• Detecting stones (sialolithiasis).

• Diagnosing infections or tumors.

• Determining gland size and shape.

2. Lymph Node Examination

• Identifying enlarged nodes due to infection or tumors.

• Differentiating between inflammatory and cancerous enlargement.

3. Diagnosis of Oral Tumors and Lesions

• Detecting masses or swellings in the lips, tongue, or floor of the mouth.

• Monitoring tumor growth after treatment.

4. Assessment of Facial and Jaw Injuries

• Detecting hematomas or fluid collections.

• Determining the extent of muscle or ligament damage.

5. Guiding Medical Procedures

• Assisting in needle guidance for biopsies from masses.

How the Scan is Performed

Preparation

• No special preparation required, but you may be asked to remove jewelry or removable dentures.

During the Scan

• A medical gel is applied to the area to improve sound wave transmission.

• The probe is moved over the target area.

• Images appear instantly on the monitor.

Duration

• Usually takes 10–20 minutes only.
