What is a cephalograph used for in dentistry?

A cephalograph is specifically used in dentistry to take a full head and neck radiograph, which is essential for orthodontic evaluation and treatment planning. This imaging technique allows dental professionals to assess the relationships between the teeth, jaws, and facial structures. It provides a lateral view of the head that includes the skull, jawline, and teeth, enabling orthodontists to analyze growth patterns, tooth alignment, and skeletal relationships.

The use of a cephalograph is particularly valuable for diagnosing malocclusions and planning orthodontic treatments. By examining these radiographs, dental professionals can gather crucial information regarding the position of teeth and bone structure, which plays a significant role in the development of effective treatment plans.

In contrast, the other options relate to different dental procedures or areas of focus. For instance, examining dental caries involves visual and clinical assessments rather than radiographic imaging specific to the head and neck. Assessing gum inflammation usually requires periodontal examinations, not an overall head radiograph. Taking impressions for orthodontics typically involves physical molds of teeth rather than a radiographic technique. Thus, the cephalograph's primary function in capturing detailed, full head and neck radiographs clearly highlights its significance in orthodontics.
