Effect of continuous versus intermittent orthodontic forces on root resorption: A microcomputed tomography study
Ozkalayci, Nurhat; Karadeniz, Ersan Ilsay; Elekdag-Turk, Selma; Turk, Tamer; Cheng, Lam L.; Darendeliler, M. Ali (E H Angle Education Research Foundation, Inc, 2018)Objectives: To compare the extent of root resorption and the amount of tooth movement between continuous orthodontic force and intermittent orthodontic force that was activated in a similar way to a 4-week orthodontic ... -
Physical properties of root cementum: Part 13. Repair of root resorption 4 and 8 weeks after the application of continuous light and heavy forces for 4 weeks: A microcomputed-tomography study
Cheng, Lam L.; Turk, Tamer; Elekdag-Turk, Selma; Jones, Allan S.; Petocz, Peter; Darendeliler, M. Ali (Mosby-Elsevier, 2009)Introduction: The reparative process of root absorption begins in the periodontium when orthodontic force is discontinued or reduced below a certain level. Our aim was to evaluate cementum repair at 4 and 8 weeks of retention ... -
Physical properties of root cementum: Part 16. Comparisons of root resorption and resorption craters after the application of light and heavy continuous and controlled orthodontic forces for 4, 8, and 12 weeks
Paetyangkul, Anchalee; Turk, Tamer; Elekdag-Turk, Selma; Jones, Allan S.; Petocz, Peter; Cheng, Lam L.; Darendeliler, M. Ali (Mosby-Elsevier, 2011)Introduction: Orthodontic force duration can affect the severity of root resorption. The aim of this clinical study was to investigate the amounts of root resorption volumetrically after the application of controlled light ... -
Physical properties of root cementum: Part 19. Comparison of the amounts of root resorption between the right and left first premolars after application of buccally directed heavy orthodontic tipping forces
Ho, Caroline; Turk, Tamer; Elekdag-Turk, Selma; Jones, Allan S.; Petocz, Peter; Cheng, Lam L.; Darendeliler, M. Ali (Mosby-Elsevier, 2011)Introduction: Previous studies have used the right and left sides of the same jaw to compare different force levels, types of movement, and durations of forces. However, the amounts of root resorption have not been compared ... -
Physical properties of root cementum: Part 23. Effects of 2 or 3 weekly reactivated continuous or intermittent orthodontic forces on root resorption and tooth movement: A microcomputed tomography study
Aras, Banu; Cheng, Lam L.; Turk, Tamer; Elekdag-Turk, Selma; Jones, Allan S.; Darendelilerf, M. Ali (Mosby-Elsevier, 2012)Introduction: The force application period is a modifiable factor in root resorption. There is still ambiguity if the continuity of force application is advantageous in terms of root resorption and tooth movement. In this ... -
Rate of tooth movement under heavy and light continuous orthodontic forces
Yee, Jason A.; Turk, Tamer; Elekdag-Turk, Selma; Cheng, Lam L.; Darendeliler, M. Ali (Mosby-Elsevier, 2009)Introduction: The aim of this study was to measure the rate and the amount of orthodontically induced tooth movement under heavy (300 g) and light (50 g) continuous forces with superelastic nickel-titanium closing coils ... -
Repair of root resorption 4 and 8 weeks after application of continuous light and heavy forces on premolars for 4 weeks: A histology study
Cheng, Lam L.; Turk, Tamer; Elekdag-Turk, Selma; Jones, Allan S.; Yu, Yan; Darendeliler, M. Ali (Mosby-Elsevier, 2010)Introduction: Repair of root resorption cavities has been studied under light microscopy, scanning electron microscopy, and transmission electron microscopy. The aim of this investigation was to demonstrate the use of ...
