Gingival Crevicular Fluid Alkaline Phosphatase as Skeletal Growth Indicator

assessment of the pubertal growth spurt in growing Egyptian female patients by using a simple, quick and easy method, through taking a gingival crevicular fluid alkaline phosphatase sample and measuring its concentration. Comparing the concentration of GCF ALP to the standardized middle phalanax of the middle finger MP3 we can predict if it can be an accurate and reliable method as skeletal growth indicator.
