ABSTRACT
Objective:To introduce a self-made film holder for standardized alignment of intraoral film and to evaluate its validity.Methods:The film holder,consisting of film backing,bite block and indicating part,was made of a kind of transparent material.20 patients were photographed using the film holder for serial dental films and another 20 patients were photographed using conventional bitewing instrument.The distance between the cemento-enamel junction and alveolar crest and the distance between cemento-enamel junction of adjacent teeth were measured on the serial films taken in the two groups.Results:The films taken by the use of film holder showed greater reproducibility than those by bitewing.Variables changes were significant smaller in film holder group than those in bitewing group.Conclusion:The film holder can be used as a instrument for standardized alignment of intraoral film.
