Dental Student Perceptions of Distance Education over Time: A Mixed-Methods Study.

Objectives: Amid the COVID-19 pandemic, the transition to distance learning raised pertinent questions regarding advantages and challenges compared to traditional in-person learning. This study aimed to investigate dental students' perceptions of distance learning throughout the pandemic, examining its impact on their education.

Methods: This study employed a convergent mixed-methods design.

Multi-level Factors Influencing Decisions About Stopping Surveillance Colonoscopy in Older Adults: a Qualitative Study.

Background: Little is known about patient or provider experience and perceptions of stopping surveillance among older adults with a history of colon polyps. While guidelines recommend ceasing routine colorectal cancer screening in adults  > 75 years and those with limited life expectancy, guidance for ceasing surveillance colonoscopy in those with prior colon polyps suggests individualizing recommendations.

Objective: Identify processes, experiences, and gaps around individualizing decisions to stop or continue surveillance colonoscopy for older adults and areas for improvement.

Systematic review of outbreaks of COVID-19 within households in the European region when the child is the index case.

Objectives: This systematic review aims to identify the secondary attack rates (SAR) to adults and other children when children are the index cases within household settings.

Methods: This literature review assessed European-based studies published in Medline and Embase between January 2020 and January 2022 that assessed the secondary transmission of SARS-CoV-2 within household settings. The inclusion criteria were based on the Population, Exposure, Outcome framework for systematic reviews.

Penetrating Midface Trauma: A Case Report, Review of the Literature, and a Diagnostic and Management Protocol.

Purpose: Penetrating facial trauma is an uncommon injury, but patients who present with these dramatic situations require special consideration. We describe the case of a young man who had been shot with an arrow that deeply penetrated his midface as well as report the results of a literature review of penetrating midface injuries. The information gathered was used to create a diagnostic protocol for patients who sustain such injuries.

Cross-sectional study of the association between serum perfluorinated alkyl acid concentrations and dental caries among US adolescents (NHANES 1999-2012).

Study Objectives: Perfluoroalkyl acids (PFAAs) are a class of anthropogenic and persistent compounds that may impact some biological pathways related to oral health. The objective of our study was to estimate the relationship between dental caries prevalence and exposure to four PFAA: perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS) in a nationally representative sample of US adolescents.

Setting/design: We analysed cross-sectional data from the National Health and Nutrition Examination Survey from 1999 to 2012 for 12-19-year-old US adolescents.
