Abstract

Introduction: Accurate diagnosis of proximal caries before any intervention is important because they could be remineralized if the enamel surface is remained intact and it can prevent unnecessary cavity preparation. Aim: The objectives of this study were to compare the sensitivity and specifity of different diagnosis methods including DIAGNOdent laser and an innovative approach for proximal caries detection.

Materials and methods: The sample consisted of 44 proximal surfaces from 38 patients that had suspicious radiolucency in bitewing radiography (written informed consent was obtained from each patient). The surfaces were examined by: 1.DIAGNOdent pen, 2.secondary bitewing radiography (BW) after pushing a ridiopaque material into the proximal contact (innovative approach) and 3.gentle touching by a dental explorer after placing an orthodontic separator in proximal contact for 24-48hr (gold standard).

Results: The sensitivity and specifity of DIAGNOdent pen laser were 1 & 0.919 and those of secondary BW were 0.857 & 1, respectively.

Conclusion: Considering the ease of use, safety and high sensitivity of DIAGNOdent laser, this device can be used for differential diagnosis of cavitated proximal surfaces that really need restorations. The innovative method of proximal caries detection as used in the present study can also serve as a suitable adjunct in proximal caries detection.
