Crevicular Alkaline Phosphatase Activity and Rate of Tooth Movement of Female Orthodontic Subjects under Different Continuous Force Applications
Table 3
GCF ALP activities on the tension (mesial) and compression (distal) sites of distalized maxillary canines as test tooth (TT) and mandibular canines as control tooth (CT) under 100 gm and 150 gm of orthodontic forces. Data were presented as mean and standard deviation (SD).
(A) Force 150 gm
(B) Force 100 gm
(C) Force 100 gm versus 150 gm
