What indicates clinical attachment loss in a dental patient?

The correct indication of clinical attachment loss in a dental patient is determined by measuring the distance from the cemento-enamel junction (CEJ) to the junctional epithelium. This measurement reflects the status of the periodontal support structures.

Clinical attachment loss refers to the loss of connective tissue attachment from the tooth surface and is measured as the distance from a fixed point, the CEJ, to the location of the epithelial attachment. When there is attachment loss, this distance becomes greater due to recession of the gums or further intrusions into the supportive tissues around the teeth, indicating worsening periodontal health.

Other options provide relevant information about periodontal health, but they do not specifically indicate clinical attachment loss. An increase in tooth mobility can reflect advanced periodontal disease, but it does not quantify attachment loss. The difference in probing depth between quadrants might show areas of concern in attachment, but without relating it back to the CEJ, it isn't a direct measurement of attachment loss. The presence of plaque and calculus can contribute to periodontal disease but does not itself measure attachment loss.

Understanding the correct method of assessing clinical attachment loss is crucial for evaluating periodontal status and determining appropriate treatment plans.
