This study is aimed to compare the effects of two different orthodontic forces on crevicular alkaline phosphatase activity, rate of tooth movement, and root resorption.<jats:italic>Materials and Methods<\/jats:italic>. Twelve female subjects of class II division 1 malocclusion participated. Maxillary canines with bonded fixed appliances acted as the tested teeth, while their antagonists with no appliances acted as the controls. Canine retraction was performed using nickel titanium coil spring that delivered forces of 100\u2009gm or 150\u2009gm to either side. Crevicular fluid was analyzed for ALP activity, and study models were casted to measure tooth movements. Root resorption was assessed using periapical radiographs before and after the force application.<jats:italic>Results<\/jats:italic>. ALP activity at the mesial sites peaked at week 1 for 150\u2009gm group with significant differences when compared with the 100\u2009gm group. Cumulative canine movements were significantly greater in the 150\u2009gm force (2.10<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mo>\u00b1<\/mml:mo><\/mml:mrow><\/mml:math>0.50\u2009mm) than in the 100\u2009gm force (1.57<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mo>\u00b1<\/mml:mo><\/mml:mrow><\/mml:math>0.44\u2009mm). No root resorption was in the maxillary canines after retraction.<jats:italic>Conclusions<\/jats:italic>. A force of 150\u2009gm produced faster tooth movements and higher ALP activity compared with the 100\u2009gm group and had no detrimental effects such as root
