What is the purpose of a periodontal chart?

A periodontal chart is specifically designed to document the health status of the gums and surrounding periodontal tissues. This chart provides valuable information regarding conditions such as gingivitis and periodontitis by noting pocket depths, gum recession, and the presence of any bleeding on probing. By focusing on the health of the gums, dental professionals can monitor periodontal disease progression, plan appropriate treatment, and evaluate the effectiveness of interventions over time.

The other choices do not encapsulate the primary function of a periodontal chart. While teeth health is important, a periodontal chart does not focus exclusively on the teeth. Documenting a patient's medical history is crucial for comprehensive dental care, but it falls outside the specific purpose of a periodontal chart. Overall dental appearance, while relevant to aesthetics, is not a primary focus of this specialized chart, which is dedicated to tracking gum health and periodontal conditions specifically.
