Popis: | A method, combining the standardization of radiographs with consistent radiopaque marker placement using a controlled force, is presented. Ten adult volunteers with healthy mouths were selected. Customized radiographic film holders were fabricated consisting of a plastic stent of the maxillary or mandibular arches to which a radiographic bite-block was attached. An orthodontic stainless steel tube was added and placed so that the radiographic marker could be guided repeatedly to the base of the sulcus in the same position. The radiographs were exposed using a self-adhesive grid on the periapical film. To document repeatability, measurements using the device were obtained at different time intervals: twice-a-week for the first, third, and fifth week for a total of six measurements for each volunteer. Results showed that the mean vertical and horizontal dimensions were nearly constant across the study period. The device had been shown to be accurate and enabled placement of a radiographic marker to repeatedly reach the same position in the sulcus with a good degree of precision. |
