Introduction: Study was carried out to compare the accuracy in producing digital formats of analog lateral cephalograms by taking a digital photograph and by scanning with a flatbed scanner.
Aim: To investigate whether taking a digital photograph of an analog lateral cephalometric radiograph is as accurate as using a flatbed scanner to scan the same radiograph for digitization.
Methods: Twenty lateral cephalograms were randomly selected from the records at a Dental College and Hospital in Belgaum. They were photographed with a digital camera and scanned with a flatbed scanner. Both images were then digitized with imaging software (Facad digital imaging program version 3.5). Set of predetermined measurements were transferred on all analog cephalograms. They were then measured on the imaging software. Student t test was used to test for statistically significant differences between the measurements. Statistical analysis used: Student paired t test.
Results: Angular measurements were deviating less from the original values after digitizing with both methods, but linear measurements were significantly changed.
Conclusion: It is acceptable to take photographs of analog cephalograms if only angular measurements are to be considered. However, these images cannot be accepted when considering linear measurements.
