The gum recession rate is typically measured by comparing the distance between the cementoenamel junction (CEJ) at two different time points, usually before and after treatment or over a specific period. The formula to calculate the recession rate is:
New CEJ position = Position of the cementoenamel junction after a period
Old CEJ position = Initial position of the cementoenamel junction
Time Interval = Time elapsed between measurements (in years)
