Comparative Evaluation of ICDAS, WHO and Histological Examination in Detection of Occlusal Carious Lesions / Avaliação comparativa de ICDAS, OMS e Exame histológico na detecção de lesões cariosas oclusais

A detecção de lesões cariosas oclusais através de sistemas de pontuação visual está em contínua validação com a profundidade histológica do processo de desminerização da cárie. Objetivo: O presente estudo teve como objetivo comparar o Sistema Internacional de Detecção e Avaliação de Cáries (ICDAS), o Sistema da Organização Mundial da Saúde (OMS) e o exame histológico na detecção de lesões cariosas oclusais. Material e Métodos: 20 pré-molares foram avaliados por exame visual ICDAS, OMS e exame histológico usando estereomicroscópio (SM) para a detecção de cárie oclusal. As superfícies oclusais foram avaliadas por dois examinadores, e todos os dentes foram avaliados visualmente e histologicamente. Resultados: Para cada um dos três sistemas, foi realizada uma análise do coeficiente de correlação interclasses, sendo que a diferença entre os três sistemas de detecção de cárie oclusal foi mínimo. O exame visual através da OMS registrou o maior coeficiente de intercorrelação seguido pelo sistema ICDAS, em seguida, o exame histológico, respectivamente. Conclusão: OMS e ICDAS demonstraram reprodutibilidade e precisão diagnóstica quando comparado com o exame histológico para detecção de cáries oclusais (AU)

Detection of occlusal carious lesions with visual scoring systems is in a continuous validation with the histological depth of carious demineralization. Objective: The present study aimed to compare the International Caries Detection and Assessment System (ICDAS), the World Health Organization (WHO) system and histological examination in detecting occlusal carious lesions. Material and Methods: 20 premolars were evaluated by visual examination using ICDAS, WHO and histological examination using stereomicroscope (SM) for occlusal caries detection. Occlusal surfaces were evaluated by two examiners then all teeth were visually and histologically assessed. Results: For each of three systems the inter class correlation coefficient was examined, the differences between the three systems of occlusal caries detection were minimal. The visual examination through WHO recorded the higher intercorrelation coefficient followed by ICDAS system then histological examination respectively. Conclusion: WHO and ICDAS have demonstrated reproducibility and diagnostic accuracy when compared with histological examination for detecting occlusal caries. (AU)

Toma de decisiones para el tratamiento de caries oclusales en el sistema de salud público brasileño / Decision-making for the treatment of occlusal caries in the Brazilian public health system

ABSTRACT Introduction: Caries diagnosis errors have become a public health problem. Objective: Verify the consistency in terms of decision-making between Brazilian dentists from the country's public health system and the International Caries Detection and Assessment System (ICDAS), and evaluate the influence of professional experience on the management of the decay. Methods: There are 80 dentists in the public health service of Recife city, Brazil. All dentists were invited to participate in this cross-sectional study. Forty dentists agreed to answer questions about their decision-making in relation to the treatment of occlusal caries in low, moderate and high-risk caries situations. The time of clinical experience, the use of methods for the assessment of caries risk and the lesion activity were also inquired about. The T-test was applied with a significance level of 5 por ciento to compare the correlation between the International Caries Detection and Assessment System scores regarding the mean age of participants. Results: The disagreement between the dentists and the criteria used by the International Caries Detection and Assessment System for decision-making were mainly related to the sound surfaces or lesions restricted to the tooth enamel. It was thus verified that lack of consistency for the low-risk condition reached a score of 3 (32 percent), while moderate (95 percent) and high-risk (85 percent) conditions lay at a classification code of 0. The time of professional experience was not considered to have interfered with decision-making on any scale, regardless of the risk condition of the patient (p> 0.05). Conclusions: A divergence in terms of decision-making between dentists of the public health system and the International Caries Detection and Assessment System could be observed, specifically regarding sound surfaces or surfaces with lesions restricted to the tooth enamel. Furthermore, professional experience was seen as not influencing the management of caries(AU)

RESUMEN Introducción: Los errores de diagnóstico de caries se han convertido en un problema de salud pública. Objetivo: Verificar la concordancia de la toma de decisiones entre los dentistas brasileños del sistema de salud pública del país y el Sistema Internacional de Detección y Evaluación de Caries (ICDAS), así como evaluar la influencia de la experiencia profesional en el manejo de la caries. Métodos: De los 80 dentistas que existen en servicio público de salud en la ciudad de Recife, Brasil, todos fueron invitados a participar en este estudio transversal. Cuarenta dentistas acordaron responder sobre su toma de decisión en relación con el tratamiento de la caries oclusal en situaciones de caries de bajo, moderado y alto riesgo. El tiempo de experiencia clínica, el uso de métodos para la evaluación del riesgo de caries y la actividad de la lesión también fueron cuestionados. La prueba T, para un nivel de significancia del 5 por ciento, fue aplicada para comparar la correlación entre los escores del Sistema Internacional de Detección y Evaluación de Caries en relación con el promedio de edad de los participantes. Resultados: El desacuerdo entre los dentistas y los criterios utilizados por el ICDAS para la toma de decisiones se concentró en los códigos de clasificación que representan superficies sanas o lesiones restringidas al esmalte de los dientes. Se verificó así que la falta de consistencia para la condición de bajo riesgo se concentró en la puntuación de 3 (32 por ciento), mientras que las condiciones moderada (95 por ciento) y de alto riesgo (85 por ciento) se concentraron en los códigos de clasificación de 0. El factor tiempo de experiencia profesional no interfirió en la prevalencia de concordancia de la toma de decisión para cualquier escore, independientemente de la condición de riesgo del paciente (p> 0,05). Conclusiones: Se pudo observar una divergencia en cuanto a la toma de decisiones entre los dentistas del sistema de salud pública y el Sistema Internacional de Detección y Evaluación de Caries, específicamente con respecto a superficies sanas o superficies con lesiones restringidas al esmalte de los dientes. Además, la experiencia profesional no influyó en el manejo de la caries(AU)
