Association between lesion depth and placement technique with failures requiring extraction of preformed metal crowns in primary molars. A retrospective study.

Purpose: The aim of the present study was to evaluate the factors associated with failure requiring extraction after placement of preformed metal crowns (PMCs) in primary molars. Radiographic caries depth at baseline (initial/moderate and severe) and placement technique (Conventional and Hall technique) and other patient-related variables were analysed.

Methods: Clinical and radiographic records from children aged 2-10 years who had at least one primary molar treated with PMCs between 2011 and 2019 were evaluated.

Reporting of Magnetic Resonance Enterography in Inflammatory Bowel Disease: Results of an Italian Survey.

Inflammatory bowel diseases (IBDs) are chronic disorders that require close monitoring with imaging techniques such as magnetic resonance enterography (MRE). Standardization of radiological reports is crucial for the optimal management of IBD. We surveyed Italian radiologists regarding their experiences with MRE examinations and reporting for IBD.

Effect of erosive conditions on different sealant materials used in paediatric dentistry.

To evaluate the effect of acidic challenge on erosion depth and topographic characteristics of different materials used as occlusal sealants. Two hundred specimens of five sealant materials (Fuji IX, Ketac Molar, Fuji II, Equia and Clinpro) and forty bovine teeth enamel samples (control) were prepared and exposed to acidic challenge. The specimens were immersed in four different solutions (orange juice, coke drink, citric acid or distilled water) under mildly shaken conditions for 3 days.

Perianal Fistulizing Crohn's Disease-Associated Anorectal and Fistula Cancers: Systematic Review and Expert Consensus.

Background & Aims: Perianal fistulizing Crohn's disease (PFCD)-associated anorectal and fistula cancers are rare but often devastating diagnoses. However, given the low incidence and consequent lack of data and clinical trials in the field, there is little to no guidance on screening and management of these cancers. To inform clinical practice, we developed consensus guidelines on PFCD-associated anorectal and fistula cancers by multidisciplinary experts from the international TOpClass consortium.

Growth and physiological response of proactive and reactive juvenile "tambaqui" (Colossoma macropomum) in a recirculating aquaculture system.

This study evaluated the growth and physiological response of proactive and reactive Colossoma macropomum juveniles in a recirculating aquaculture system (RAS). In Phase 1 of the experiment (50 days of cultivation), juveniles, weighing 2.16 ± 0.
