What does the gingival sulcus refer to?

The gingival sulcus is specifically defined as the space found between the free gingiva and the tooth surface. This area is significant in dental health as it is where plaque can accumulate, potentially leading to periodontal disease if not properly managed. The sulcus varies in depth among individuals but is typically around 1-3 millimeters in healthy conditions.

Understanding this anatomical feature is essential for dental assistants, as it plays a crucial role in oral hygiene practices and periodontal assessments. An accurate knowledge of the gingival sulcus helps in recognizing the signs of gingival health or disease, guiding interventions such as scaling or patient education on plaque control.
