Film‐holder device for radiographic assessment of periodontal tissues

Abstract

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.

Treatment of Supra‐Alveolar‐Type Defects by a Simplified Papilla Preservation Technique for Access Flap Surgery With or Without Enamel Matrix Proteins

“…The positions of ACL and CEJ were marked by a pencil on the radiographs and the distance ACL − CEJ (BL) was measured by a millimeter grid. Linear distances between the most coronal interproximal BL and the CEJ were obtained by counting the grids 28 …”

Enamel matrix proteins in the treatment of periodontal sites with horizontal type of bone loss

“…Radiographic measurements were obtained utilizing an adhesive millimeter grid (X‐Ray Grid 3–4 cm, Mey GmbH, Oberursel, Germany). Vertical linear distances between the CEJ and the most coronal interproximal extension of bone crest were obtained by counting the grids (Nery et al 1985). Initial bone loss as the inclusion criteria was assessed according to the position of the bone crest in relation to CEJ.…”

Efficacy of a newly designed angulation-adjustable film holder for reducing cone-cutting errors and saving time in horizontal tube-shift technique by dental students

“…The intraoral film-holding devices for the paralleling technique are commercially available with numerous designs, and their advantages/disadvantages have been evaluated [ 17 , 18 , 19 , 20 , 21 ]. To the best of our knowledge, the film holders mostly comprise a film-holding portion and a right-angle beam aiming rod (with or without an aiming ring).…”
