The primary measurement used to assess the loss of gingival attachment is taken from the cementoenamel junction (CEJ) to the base of the pocket. This measurement provides a reliable indication of the level of attachment loss due to periodontal disease. When examining periodontal health, clinicians focus on the CEJ because it serves as a fixed anatomical landmark that remains constant, while the gingival margin can fluctuate due to inflammation, recession, or other factors.

By measuring from the CEJ to the base of the pocket, dental professionals can determine the extent of attachment loss, which is critical for diagnosing the severity of periodontal disease and formulating an appropriate treatment plan. This method is essential for understanding the attachment level, especially in cases where there may be changes in the gingival margin that do not accurately reflect true periodontal health. Consequently, this measurement is crucial in assessing the overall periodontal status of a patient.
