An alternative approach to periapical radiography for gaggers

Abstract

Context: Most difficult and common problem, while taking intraoral periapical radiographs in the posterior region of the jaw is gagging. Severe gag reflex at times does not allow periapical radiography causing an additional financial burden on the patient who is then sent for extraoral radiography. Aim: The aim of this study was to device a new technique with which the radiograph of maxillary and mandibular third molars can be obtained without causing much discomfort and additional financial burden to the patient. Settings and Design: The present technique was applied and tested for its validity on the routine patients visiting oral radiology department for radiograph of maxillary or mandibular third molars and who demonstrated severe gag reflex preventing periapical radiography. Subjects and Methods: The present technique required a dental chair, intraoral dental X-ray machine, regular size of two periapical films, and artery forceps. The film is placed parallel to the occlusal plane as in case of occlusal radiography with the embossed dot side facing toward the teeth to be radiographed, and exposures were made. Results: The resulting radiographs taken by the present technique showed a complete image of third molars without causing stimulation of gag reflex and without superimposition of the zygomatic process on roots of maxillary third molars. Conclusion: The present technique can be used satisfactorily for taking third molar radiographs in patients with severe gag reflex.
