In the described periodontal case, which factor primarily determines the Grade C designation?

• A. Age of the patient
• B. Depth of periodontal pockets
• C. Presence of risk factors
• D. Number of missing teeth

Answer: (C)

Grade in periodontal assessment reflects how fast the disease is progressing, and the factor that drives a Grade C designation is the presence of risk factors that accelerate damage. When a patient has such risk factors—like smoking or poorly controlled diabetes—they can cause attachment loss to occur more rapidly, pushing the case into Grade C. Age does not by itself set the grade, and the depth of pockets relates more to how advanced the disease is (Stage) rather than how quickly it progresses. The number of missing teeth is an outcome of the disease history, not a determinant of the current progression rate. So, the presence of risk factors is the key element that designates Grade C.
