What is the role of x-rays in dental hygiene practice?

The role of x-rays in dental hygiene practice is primarily centered around their diagnostic capabilities, particularly in detecting caries (cavities) and periodontal disease. X-rays provide a detailed view of the teeth and surrounding structures that is not visible during a standard clinical examination. This imaging allows dental hygienists to identify decay that may be developing between teeth or beneath existing fillings, as well as assess the condition of the bone supporting the teeth, which is crucial for recognizing periodontal disease.

By detecting these issues early, dental hygienists can formulate appropriate treatment plans and educate patients about their oral health. This proactive approach helps in preventing more extensive and costly treatments in the future, ensuring that oral health is maintained. In contrast, other options focus on aspects that are not directly related to the primary clinical functions of x-rays in dental hygiene.
