INTRODUCTION Orthodontic tooth movement is fraught with risks and complications. Root resorption is the most frequent and important outcome which may arise due to inappropriate force magnitude or tooth movement into dense or altered bone. This study was aimed to demonstrate histologic changes in tooth roots following movement into a jaw region treated with synthetic bone substitute. Another obj...
OBJECTIVES One major drawback of orthodontic treatment is its long duration due to slow tooth movement and the pain at the onset of treatment following application of forces. There is controversy regarding the efficacy of laser for decreasing the treatment time and pain of orthodontic treatment. The purpose of this study was to investigate the effect of low level diode laser on the rate of orth...
The purpose of this study was to investigate the osteopontin mRNA expression in the alveolar bone incident to the physiologic and experimental tooth movement. The upper jaws of female rats (7 weeks old) which were submitted to experimental molar tooth movement and control specimens were decalcified and sliced into paraffin sections. Osteopontin mRNA expression and tartrate-resistant acid phosph...
Bisphosphonates (BPs) are drugs that act primarily to inhibit osteoclast activity and bone resorption, used in many clinical conditions associated with excessive bone resorption. Aim of this review is to investigate the effects of BPs on orthodontic tooth movement. All selected studies showed that orthodontic tooth movement is reduced after BPs administration, with not clear effect on root reso...
