Supra gingival calculus primarily consists of what substance?

Supra gingival calculus primarily consists of dental plaque. When dental plaque forms on the surfaces of the teeth, it is composed of bacteria, food particles, and saliva. Over time, if dental plaque is not removed through regular brushing and professional cleanings, it can mineralize and harden into calculus. This hardened plaque is what we refer to as supra gingival calculus, which is located above the gum line and can contribute to gum disease if not adequately managed.

While saliva is indeed a component of the oral environment, it is not the primary substance making up calculus. Protein debris and aging tissue also do not constitute the main components of supra gingival calculus. Understanding the process of plaque accumulation and mineralization is crucial for dental professionals as it highlights the importance of oral hygiene in preventing the formation of calculus and maintaining overall periodontal health.
