The correct answer is: Above the gingiva

Supragingival calculus is the type of dental calculus that forms on the surfaces of teeth above the gum line, making it easily visible during oral examinations. This hardened plaque is primarily composed of mineralized bacterial biofilm and typically accumulates in areas where saliva is present, such as near the salivary gland openings. When considering the context of dental hygiene and the significance of calculus control, recognizing that supragingival calculus can lead to various oral health issues, including gingivitis and periodontitis, highlights the importance of regular dental cleanings and personal oral hygiene practices. Understanding the location of supragingival calculus is essential for dental professionals to effectively evaluate a patient's oral health and recommend appropriate treatment.
