Object localization technique in dentistry – A review

Abstract

Background: A dental radiograph is a two-dimensional view for a three-dimensional object present in the jaws. Many times diagnosis becomes difficult for a clinician due to the impacted teeth, supernumerary tooth, or foreign objects. These objects can be localized using various techniques using periapical radiograph, orthopantomograph, and advanced imaging techniques. Tube shift technique, right angle technique, magnification method, vertex occlusal method, stereoscopy, panoramic localization, lateral skull, and posteroanterior view are various techniques which have been used to locate objects. It becomes important for every dentist to know about each technique and its indications. There is a scarcity in the literature which reviews various techniques of object localization. Thus, this article reviews various techniques of object localization in dentistry. Aim: This study aims to review on various techniques used for object localization in dentistry and its indications. Conclusion: Object localization technique is an easy, convenient, cost effective. This article gives an insight regarding various techniques used since past and its applicability in various indications. Clinical Significance: Object localization technique can be applied by a dentist in a day-to-day practice, rather exposing the patient to the advanced screening methods.
