Parental attitude toward children's oral health during COVID-19 pandemic: a cross-sectional study in Italy.

Aim: During the COVID-19 pandemic, restrictive rules were imposed around the world to limit the spread of the virus. The present study aims to investigate how the pandemic and the consequent restrictions have affected the lives and oral health of Italian families with children aged 0-14 years.

Materials: Through a questionnaire distributed online from December 2020 to March 2021 the following aspects were investigated: family income during the pandemic, fear of the pandemic, dietary habits, perceived risk of infection in a dental practice and perceived children oral health status during the pandemic.

Plasma-Induced Catalyst Support Defects for the Photothermal Methanation of Carbon Dioxide.

The presence of defects in a catalyst support is known to benefit catalytic activity. In this work, a He-plasma treatment-based strategy for introducing and stabilising defects on a Ni/TiO catalyst for photothermal CO hydrogenation was established. The impact of pretreatment step sequence-which comprised He-plasma treatment and reduction/passivation-on defect generation and stabilisation within the support was evaluated.

Oral manifestations in paediatric patients with hepatobiliary diseases: a review.

It is well known that greenish pigmentation of the teeth is seen in children following remission of severe jaundice and clinical and serum bilirubin, a degradation product of haemoglobin, may be permanently trapped in forming dental hard tissues causing discolouration and enamel and dentine hypoplasia. Neonatal jaundice is the most common cause of hyperbilirubinemia and pigmentation of the deciduous teeth is the consequence of this condition. Various hepatobiliary pathologies may have a clinical finding in the oral cavity; furthermore, oral manifestations of hepatic pathologies are not just limited to the pigmentation of the deciduous teeth but also the permanent dentition and the mucous membranes can be affected.
