Background: Dental surgeons very frequently encounter the cases of dental caries are one of the most commonly encountered conditions. Such lesions remain undetected when confined to the vicinity of inter-proximal surfaces. Aim: To test the ability of E-speed film, complementary metal oxide semiconductors and storage phosphor systems in the detection of proximal caries of the posterior teeth. Methods: Carious surfaces with demineralization appearing as chalky white or brownish discoloration on proximal surfaces were included in this study. Conventional films, CMOS and PSP images were used in detecting proximal caries on mesial and distal surfaces of teeth. Results: Lesions were equally distributed on both PSP and CMOS images (sixty nine each) that means the lesion is more accurately visible in digital receptor and presence of initial caries is more appreciated in PSP (26) than in CMOS (25) and IOPA (23) which shows that PSP is more accurate in detecting early lesions and the deeper lesions were more visible in IOPA images (12) in comparison with CMOS (8) and PSP (7) that means IOPA have lesser ability to detect the presence of initial forms of caries and also in delineating the actual depth of the caries. Conclusion: PSP is more accurate in detecting early lesions and the deeper lesions were more visible in IOPA images. Lesion is more accurately visible in digital receptor and presence of initial caries is more appreciated.
