In dental radiography, what does the term "fog" refer to?

In dental radiography, the term "fog" specifically refers to unwanted exposure that leads to a decrease in image quality. This unintended exposure can result from various sources, such as scatter radiation, light leaks in the darkroom, or even poor handling of the film. When fog occurs, the radiographic image may appear hazy or cloudy, obscuring important details and making it difficult for the dentist or radiologist to interpret the results accurately.

Understanding this concept is crucial for maintaining high-quality imaging standards, as it directly impacts diagnostic capabilities. By minimizing fog, practitioners can ensure that the radiographs produced provide clear and useful information, facilitating appropriate treatment planning and patient care.
