Conservative dentistry in primary dentition aims to remove and repair existing carious lesions and to prevent secondary caries up until exfoliation of the primary tooth happens, in order to maintain the important role in terms of the space maintenance and guidance for eruption that deciduous teeth have. Many different materials are used, and some of them, recently commercialized, show bioactive properties able to prevent secondary caries. This trial's primary focus is to evaluate the biological, functional, and aesthetic characteristics of Cention-N alkasite material compared to glass ionomer cement (GIC) through the use of standardized FDI criteria for direct restorations. A blinded, split-mouth study was designed for this purpose, including 112 deciduous molars in 45 children showing class II caries restored with either GIC or alkasite material. The data from this study indicates that the Cention-N alkasite material showed equal performance compared with Fuji IX GIC after one year. A thorough evaluation of exfoliated teeth restored with this material will provide long-term data and an evaluation on infiltration rates. [ABSTRACT FROM AUTHOR]

Background: The original English version of the questionnaire 'Parental Perceptions of SDF Dental Color Changes' was used among parents in the New York City metropolitan area. Aim: To develop an Italian version of the questionnaire and to assess its validity. Design: The construct validity and the internal consistency were assessed in a convenience sample of Italian parents of 251 young healthy children seen at the University of Bologna and Pisa. Forward‐backward technique was carried out for the translation of the questionnaire. Kaiser‐Meyer‐Olkin measure of sampling adequacy was equal to 0.91, and Bartlett's test of sphericity was statistically significant (P =.001), so the items were treated with the exploratory principal component analysis (PCA). Results: Cronbach's alpha ranged from 0.69 to 0.95. PCA demonstrates that all the items load on the first component (87% of explained variance). All the Spearman correlation coefficients between each subscale (positive scenario: 0.563; negative scenario: 0.665) and the general acceptability showed significant correlation (P =.0001). Different age, educational level, and family income of the parents did not produce statistically significant different scores on any of the subscales (P >.05; Mann‐Whitney test). Conclusion: The Italian version of the questionnaire showed high internal consistency and construct validity and was appropriate to be used in an Italian population. [ABSTRACT FROM AUTHOR]

Literature reviews are crucial in the choice of the best personalized material type and restauration type in restorative dentistry. We developed an IBMWatson based system to support literature search for restorative dentistry, and compared its results to a literature search performed by a trained professional. We found that our system could assist the researcher in performing a literature review, but the grounding semantic model needs to be refined in order to provide more extensive results.
