Objective: The aim was evaluate the validity and reproducibility of the International Caries Detection and Assessment System (ICDAS) in detecting occlusal caries among graduate students after training using the e-learning program. Methods: A sample of forty-two primary teeth with different ranges of occlusal caries was selected. All teeth were mounted on a wax support and standardized photographs (EOS Rebel XTI, Canon, NY, USA) of the occlusal surfaces were taken. An experienced researcher randomly selected one specific site on the occlusal surface of each tooth to be examined later. Fifteen graduate students with no previous experience in the ICDAS scores completed the ICDAS e-learning program in Portuguese. After the training, visual examination of the occlusal surfaces was taken twice, independently, with a two-week interval. After visual examination, the teeth were longitudinally sectioned 1mm away from the previously selected occlusal site. The teeth were fixed on a wax support and photographed. Histological analysis was performed from these photographs by an experienced researcher to evaluate the depth of demineralization. Results: The Intraclass Correlation Coefficient (ICC) inter-examiner values among all participants varied from 0.54 to 0.96 and intra-examiner ICC reproducibility of the examiners ranges from 0.61 to 0.85, showing good to excellent reproducibility. For detection of enamel and dentine lesions (D1), ICDAS obtained sensitivity 0.835 and specificity 0.756. For dentine lesions (D3), the method revealed an increase in sensitivity but specificity was similar to D1. Conclusion: ICDAS e-learning training program was efficient for the training of caries lesions detection among graduate students.

Objective To evaluate the association between cleft lip and/or cleft palate (CL/P) and breastfeeding (BF). Design A systematic review and meta-analysis were performed based on studies published in PubMed, Scopus, Web of Science, Cochrane Library, LILACS, BBO, and Embase databases, and in the gray literature. The search occurred in September 2021 and was updated in March 2022. Observational studies evaluating the association between BF and CL/P were included. Risk of bias was analyzed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was conducted. Certainty of evidence was evaluated using the GRADE approach. Main Outcome Measure(s) Frequency of BF in relation to the presence or absence of CL/P, as well as to the type of CL/P. The association between cleft type and BF challenges was also evaluated. Results From a total of 6863 studies identified, 29 were included in the qualitative review. Risk of bias was moderate and high in most studies (n = 26). There was a significant association between the presence of CL/P and absence of BF (OR = 18.08; 95% CI 7.09–46.09). Individuals with cleft palate with or without cleft lip (CP ± L) had a significantly lower frequency of BF (OR = 5.93; 95% CI 4.30–8.16) and a significantly higher frequency of BF challenges (OR = 13.55; 95% CI 4.91–37.43) compared to individuals with CL. Certainty of the evidence was low or very low in all analyses. Conclusion The presence of clefts, especially those with palate involvement, is associated with higher chances of absence of BF.
