Understanding Dental Radiography

Dental radiography is an indispensable diagnostic tool that allows dental professionals to view the structures of the mouth that are not visible to the naked eye. This imaging technology is crucial for identifying and treating oral health issues such as decay, bone loss, and abnormalities in the root and jaw structures.

Types of Dental Radiographs

Intraoral X-rays: These are the most common type of dental X-rays, where the film is placed inside the mouth. They provide a high level of detail and are used to check for cavities, monitor the health of the tooth root and surrounding bone, or track the development of teeth.
Panoramic X-rays: The film is outside the mouth, providing a broad view of the entire dental arch, jaw, sinuses, and temporomandibular joints.
Cephalometric projections: These X-rays capture the side of the head and are used primarily in orthodontics.
Cone Beam Computed Tomography (CBCT): Offers three-dimensional imaging. CBCT is useful for complex cases involving surgical planning, implant placement, and evaluation of dental structures.
Digital Radiography: Uses electronic sensors instead of X-ray film. This technology reduces radiation exposure and allows immediate image preview and manipulation.

Radiographs allow the detection of problems at an early stage, leading to more effective and less invasive treatments. By seeing what is invisible to the naked eye, dentists can diagnose conditions that might otherwise go unnoticed.
