Desenvolvimento e avaliação de software (calibra) com fotografias para calibração de escores de cárie dentária

Abstract

Objective: To develop, validate an online calibration platform for dentists and evaluate the use of photographs as a training course for the World Health Organization (WHO). Methodology: For the development of the platform Calibra was used a language in Hypertext Preprocessor (PHP) and Structured Query Language (SQL) for programming access forms and database. An ISO and IEC standard containing adaptations was used for software evaluation. To evaluate the use of training videos, the sample consisted of 39 dental surgeons (CD) examiners who were randomly divided into 4 groups, group 1 (n = 9) was calibrated in vivo 1 and in vivo 2, the group 2 (n = 12) in lux, in vitro, in vivo 1, group 3 (n = 7) in lux, in vivo 1 and in vivo 2 and group 4 (n = 11) in vitro, in vivo 1 and in vivo 2. The standard adopted for calibrations was requested by the World Health Organization (WHO). All groups participated in theoretical training on the WHO theme. After this training, the groups participated in their respective calibrations. All steps were conducted by a gold standard instructor. The equipment used for in lux and in vitro calibrations was a questionnaire that should not be evaluated and slipped for each occlusal surface by means of photographs or tactile-visual, respectively. For in vivo calibration, the test corresponds to a clinical examination sheet, containing the odontogram. At the end, a histological analysis of the extracted teeth was carried out in order to infer the sensitivity and specificity levels of the calibration methods in lux, in vitro. The data from the collection were compared using the Kappa coefficient in each calibration group, in order to obtain inter and intra-examiner concordance levels. Results: developed and evaluated for the operation of the Calibra platform. The Kappa G1 inter-rater in vivo 1 is 0.82 in vivo 2 0.79, Kappa G2 in lux 0.54, in vitro 0.64, in vivo 1 0.87, Kappa G3 in lux 0.59, in vivo 1 0.79, in vivo 2 0.87, Kappa G4 in vitro 0.52, in vivo 1 0.82 in vivo 2, 0.83. The maximal and minimum ranger of Kappa G1 in vivo 1 0.63-0.91, in vivo 2 0.49-1.00, G2 in lux 0.37-0.73, in vitro 0.40-0.60, in vivo 1 0.46- 1.00, G3 in lux 0.37-0.85, in vivo 1 0.65-0.91, in vivo 2 0.67-0.95, G4 in vitro 0, 21- 0.81, in vivo 1 0.52-0.88, in vivo 2 0.75-1.00. Conclusion: The Calibra Platform, despite not replacing live calibration, is an innovative educational tool that can be used to establish the WHO criteria for the detection of CD field performance.
