Comparison of the picture quality of two digital cameras

Comparison of the picture quality of two digital cameras when used for dental photography A.H. Grotius*, L.H. Becker, University of Pretoria, Pretoria, RSA

Introduction:With the tremendous advances in digital technology in recent years, more and more clinicians are using it to their advantage. In addition to digital patient records and radiographs, digital dental photography offers the dental professional another possibility of record keeping and visual reconstruction of the various stages of treatment. Changes, often difficult to identify in retrospect, frequently occur in complex cases over long periods of time. A photographic archive provides a way to record initial findings and makes detailed assessment of minor changes in hard and soft tissue over long periods of time possible. Degradation of dental restorations and different materials are easily identified during follow-up appointments, allowing dental professionals to evaluate the treatment outcome. To achieve the aforementioned advantages it is critically important to get the best possible recording of the true intra-oral situation. Method: The cameras assessed were the Nikon Coolpix 995 and the Kodak EasyShare DX6490. Photographs were taken of mounted models using a tripod and in the clinical setting. The exposure was controlled and standardized for both cameras through manipulation of the shutter speed, aperture and camera-subject distance. The photographs taken were evaluated and compared on the criteria for sharpness, depth of field and replication of the true colour. Results: and Conclusion: The results indicate that digital photography can be used to obtain acceptable photographs for purposes of diagnosis and record keeping in dentistry.
