This is the only intraoral radiographic technique which requires an intra-oral cassette with intensifying screen. However such intraoral radiographic cassettes are not readily available in the Indian market. Hence this study was taken up to fabricate an intraoral radiographic cassette using a dismantled extraoral radiographic cassette and to assess the efficacy of this cassette in obtaining vertex occlusal radiographs and comparing the image quality and exposure parameters between occlusal radiographs with and without the intraoral cassette. Materials and Methods: dismantled fragments of extraoral radiographic cassette and endofiles box were basically used to fabricate an intraoral radiographic cassette. 25 patients were involved in the present study for obtaining various types of occlusal radiographs with and without the usage of fabricated intraoral cassette. Five oral radiologists were involved in assessing the efficacy of the fabricated intraoral radiographic cassette in obtaining and interpreting vertex occlusal radiographs. They further compared the image quality and exposure parameters between occlusal radiographs obtained with and without fabricated intraoral cassette. Results: Vertex occlusal radiographs obtained with usage of fabricated intraoral cassette were successfully obtained in which interpretation of normal anatomy and identification of buccal cortical plate and buccopalatal localization of impacted canines was possible in all the situations. The image quality of occlusal radiographs obtained with intraoral cassette was found to be inferior when compared to the direct film occlusal radiographs. Conclusions: fabricated intraoral radiographic cassette is useful in obtaining vertex occlusal radiographs. The image quality of other occlusal radiographs obtained with intraoral cassette, though inferior to their counterparts, is still good enough for recognition and interpretation of anatomy and pathology of jaws since usage of intraoral radiographic cassette for obtaining occlusal radiographs would reduce the radiation exposure to the patient by at least fifty percent.

INTRODUCTION An occlusal radiograph is an intra oral radiographic technique designed to be placed between the occlusal surfaces of the teeth with the central beam directed at 90degrees or at 50-60 degrees to the plane of the film depending on what is required to be viewed. True/cross sectional occlusal radiographs are taken to assess the buccolingual cortical plate status of the
