OBJECTIVES To evaluate the accuracy of using routine 2-dimensional (2D) radiographs (panoramic and periapical) when evaluating the position of orthodontic temporary anchorage devices (mini-implants) in the maxilla, and to compare the results to 3-dimensional cone-beam computed tomography (CBCT). METHODS This cross-sectional study was conducted at King Abdulaziz University, Faculty of Dentistr...

controlled environment may be adopted for a rapid multiplication of a large number of potato seed tubers. the controlled environment prevents seed tuber degeneration which may occur under field conditions. the objective of this study was to introduce new mini-tuber production system with high multiplication rate and low production cost. to evaluate the performance of culture systems in terms of...

BACKGROUND Optimal positioning of orthodontic mini-implants is essential for a successful treatment with skeletal anchorage. This study aims to compare the accuracy of two-dimensional radiographs with a cone beam computed tomography (CBCT) for mini-implant placement. METHODS An ideal site for mini-implant placement at the buccal interradicular space between the second premolar and the first m...

BACKGROUND Mini C-arm devices have gained popularity in extremity surgery. There is little evidence of the benefits of this technique in the clinical setting of foot and ankle surgery. We used dose area product (DAP) to compare radiation usage between mini C-arm and standard fluoroscopy. METHODS We prospectively reviewed 127 cases requiring intra-operative screening during elective foot and a...
