Erosive potential of children's chewable vitamin supplements: An in vitro investigation.

Background: Chewable vitamins are dietary supplements in which vitamins are combined with a flavor that appeals to children. The acidic nature of some vitamins and some flavoring agents may cause dental erosion. We investigated the effect of children's chewable vitamin supplements on the loss of minerals in teeth.

Characteristics and influencing factors of the first dental visit among children in Bangkok, Thailand: a cross-sectional study.

Background: The first dental visit (FDV) is fundamental to good oral health. This study aimed to investigate the characteristics of FDV, including the influencing factors, in children attending the government dental hospital in Bangkok.

Methods: This study included 289 pairs of new patients (aged 0-12 years) and their parents.

Efficacy of Dental Barriers in Aerosols and Splatters Reduction During an Ultrasonic Scaling: An Study.

Background: Barrier enclosure systems were suggested as the protective equipment for aerosol-generating procedures.

Objective: The aim of this study was to investigate the efficiency of dental barriers in aerosols and splatters reduction during an ultrasonic scaling.

Materials And Methods: Two types of dental barriers: (1) metal frame with plastic wrap (MFPW) and (2) plastic shield chamber (PSC) were investigated.

Efficacy of extraoral suction devices in aerosol and splatter reduction during ultrasonic scaling: A laboratory investigation.

Ultrasonic scaling generates aerosols and splatters contaminated with microorganisms, increasing the risk of disease transmission in the dental office. The present study aimed to evaluate the effectiveness of extraoral suction (EOS) units in aerosol and splatter reduction during ultrasonic scaling. Ultrasonic scaling was conducted on a dental manikin headset to simulate a scaling procedure.

Up-regulation of interferon-stimulated gene 15 and its conjugation machinery, UbE1L and UbcH8 expression by tumor necrosis factor-α through p38 MAPK and JNK signaling pathways in human lung carcinoma.

Interferon-stimulated gene 15 (ISG15) is a member of the family of ubiquitin-like proteins. Similar to ubiquitin, conjugation of ISG15 to cellular proteins requires cascade reactions catalyzed by at least 2 enzymes, UbE1L and UbcH8. Expression of ISG15 and its conjugates is up-regulated in many cancer cells, yet the underlying mechanism of up-regulation is still unclear.
