Comparison of three camera systems in intraoral photographs

Abstract

Objective: Identify the camera system that has the best features for intraoral photography, evaluating five aspects: sharpness, depth of field, exposure, white balance and image composition on each photograph and observe which system obtains better results. Methodology: The following study is observational analytical cross-sectional; in which 45 intraoral photographs were evaluated, which were the product of three different camera systems: 15 from a Canon Camera (Reflex), 15 from a Sony Camera (Compact) and 15 from an IPhone 7 Camera (Mobile Device). The evaluation was carried out based on the 5 aspects mentioned in the objective by three teachers from the FDCUE, who did not know with which camera system the photographs they were evaluating were taken. The results obtained were statistically analyzed in the SPSS program, and the Fisher's exact test was applied to assess the difference between the groups. Results: Reflex 68.89%, Compact: 37.78%, iPhone 7: 35.56%. Depth of field: Reflex: 84.44%, Compact: 44.44%, iPhone 7: 51.11%. Exposure: Reflex: 88.89%, Compact: 51.11%, iPhone 7: 28.89%. White balance: Reflex: 86.67%, Compact: 53.33%, iPhone 7: 22.22%. Composition: Reflex: 73.33%, Compact: 46.67%, iPhone 7: 33.33%. Conclusions: It was determined through the statistical results among the three camera systems that the reflex camera was the one that had the best results in all the proposed fields, with a significant difference, especially compared to the camera of the mobile device (iPhone 7).
