Abstract

Introduction: early detection of interproximal caries is important for prevention and conservative treatment. In clinic, because of the lack of direct vision and tactile in inter dental area, usually Para clinical examination such as bitewing and digital radiography uses caries detection.

Aim of study: The aim of this study was to evaluate the sensivity of laser fluorescence (LF) using Diagnodent pen compared to conventional Bitewing (BW) and Digital Radiography (DR).

Materials and Methods: 18 primary molars in 12 children (aged 8-12 years), which were indicated for extraction, were included. After obtaining consent from parents, samples evaluated for dental caries using Diagnodent, bitewing radiographs and digital radiography. Histologic examination was performed after the teeth were examined by all the three methods and served as the gold standard.

Result: the values obtained for the sensitivity, specificity of LF were 85.19 and 84.34% , for bitewing were 81.48 and 81.93% and for digital radiography 48.15% and 49.40%.

Conclusion: Diagnodent showed higher sensitivity and specificity as compared with other conventional methods for detection of interproximal caries.
