Usefulness and satisfaction of a digital learning tool for caries detection using ICDAS / Utilidade e satisfação de uma ferramenta digital de aprendizado para detecção de cárie utilizando ICDAS

Objective: this study aimed evaluate the usefulness and satisfaction of a digital learning tool (DLT) using ICDAS (International caries detection and assessment system) created for learning and training visual detection of carious lesions in a non-controlled setting. Material and Methods: the DLT containing 60 pictures of sound and carious surfaces was distributed through social media and professional associations, aiming at both dentists and dental students. Analysis was based on data collected through a personal, professional and satisfaction questionnaire and Google Analytics. Results: a total of 2300 users accessed the DLT and 1517 completed it, filling out the questionnaires. Users required 2.29 sessions to accomplish the DLT in an average time of 15 min and 14 seconds each. The satisfaction questionnaire showed that 84.8% of users found in the DLT exactly what they expected and 91.8% found it useful. Around 88.4% of users found that the DLT helped in discussion of ICDAS with colleagues and 88.9% with superiors; 88.3% found that the DLT provided immediate learning results. The DLT was most useful to dental students (83.7% of users), and overall satisfaction was 86%. Conclusion: users found the DLT useful for learning and training visual detection of carious lesions using ICDAS, and general satisfaction was high. (AU)

Objetivo: o objetivo deste estudo foi avaliar a utilidade e a satisfação de uma ferramenta digital de aprendizado (FDA) utilizando o ICDAS (International caries detection and assessment system), criada para aprender e treinar a detecção visual desse índice de forma virtual. Material e Métodos: a FDA contendo 60 fotos de superfícies hígidas e cariadas foi distribuída por meio de mídias sociais, visando profissionais e estudantes de odontologia. A análise baseou-se nos dados recolhidos através de um questionário de satisfação da experiência e Google Analytics. Resultados: um total de 2.300 usuários acessaram a FDA e 1.517 a completaram até os questionários. Os usuários precisaram de 2,29 sessões para realizá-la em um tempo médio de 15 min e 14 segundos. O questionário de satisfação mostrou que 84,8% dos usuários encontraram exatamente o que esperavam e 91,8% a acharam útil. Cerca de 88,4% dos usuários acreditaram que a FDA ajudou na discussão do ICDAS com colegas e 88,9% com superiores; 88,3% acharam que foi fornecido resultados de aprendizagem imediatos. A FDA foi mais útil para estudantes de odontologia (83,7% dos usuários) e a satisfação geral foi de 86%. Conclusão: os usuários acharam a FDA útil para aprender e treinar a detecção visual de lesões cariosas utilizando o ICDAS. A satisfação geral alcançada foi considerada alta. (AU)

Influence of Isolation Technique on the Survival of Resin-Modified Glass-Ionomer Restorations in Primary Molars: A 9-Months Randomized Controlled Trial

ABSTRACT Objective: To compare the survival of occlusal and occlusal-proximal restorations performed with resin-modified glass-ionomer cement (RMGIC) in deciduous molars using rubber dam and cotton rolls isolation. Material and Methods: Ninety-two patients were included and 200 deciduous molars with cavitated occlusal or occlusoproximal dentin caries lesions were randomized into two groups: cotton rolls (n = 100) and rubber dam (n = 100) and RMGIC restorations were placed. At baseline and in the follow-up visit, presence, severity and activity of caries lesions were registered. Two independent, blinded examiners evaluated the treated teeth clinically using the USPHS criteria and radiographically after 9 months. Descriptive analysis, survival curve (log-rank test) and Cox regression were performed to assess risk factors related to failure. Results: Out of the 179 teeth (92 cotton rolls group and 87 rubber dam group) evaluated at 9-month follow-up period. No lesion progression was observed radiographically. The overall treatment success rate was 85.47% (83.47% for cotton rolls and 87.35 rubber dam group). No significant difference between isolation methods was observed in the log-rank test (p = 0.16). Cox regression showed no risk factors related to failure. Conclusion: No difference was found in the survival of occlusal and occlusal-proximal restorations performed with RMGIC in deciduous molars using a rubber dam and cotton rolls isolation after a 9-month follow-up period.
