ABSTRACT

We live in a world of evidence-based medicine, which requires substantiation of every action or diagnosis established with a certain amount of accountability. The adjunctive use of modern technology and its advancements in the field of diagnostic imaging has evolved over the past few years. These advancements include the judicious use of cone beam computer tomography and ultrasound real time imaging with colour power Doppler. However, all these advances till date cannot be declared as the gold standard as they are either not cost effective or are extremely technique sensitive which means they cannot be applied on a large scale to diagnose periodontal pathologies. Apart from just these drawbacks there are also concerns regarding the dose of radiation exposure while taking an IOPA and an OPG, where OPG is at an advantage being an extra-oral radiation exposure source. With these limitations in mind the rationale behind the present study was to use currently available affordable means of diagnostic imaging in the form of Radio-visual-grams and Ortho-Panto-grams to predict the underlying bone morphology as compared to the gold standard of exploratory surgery of periodontal defects. The results obtained suggest RVG are diagnostically more accurate to capture individual site bone levels as compared to OPG and also portrait a closer picture to the actual Bone defect while the OPG seem to exaggerate the size of the defect extensively depending on the depth of the defect.
