Abstract

Aim:  Compare diagnostic accuracy of radiovisiography and transperiodontal probing with intrasurgical measurements for assessment of interproximal bone loss. Methods and Material: A total of 6 patients with 30 sample sites having proximal bone loss were included in the study. The RVG reading was recorded. A plugger with a stopper was used for probing and a digital calliper for measurement to achieve the accurate result. The patient was scheduled for flap surgery and after administering the local anaesthesia, the distance between stent and the deepest point on bone was recorded. For the third reading, flap was raised and the distance from stent to the bone was recorded by plugger was measured with the calliper.  Results: For the 30 samples mean value of defect depth is 12.65±1.64 mm for RVG which is lesser than both Intrasurgical (13.97±1.84) mm and trans periodontal probing (13.90±1.82) mm.  Conclusions: The results showed that in spite of using a grid and paralleling technique for taking RVG, the readings of trans periodontal probing were closest to the gold standard (Intrasurgical) measurements.
