Article Synopsis
  • The upper airway epithelium acts as a crucial barrier against microbes, with specific areas being more prone to imbalance and inflammation.
  • Researchers analyzed human oral mucosa using single-cell RNA sequencing to identify a mix of bacterial signatures and their effects on epithelial responses in different inflammatory conditions.
  • Findings showed that persistent bacterial molecules in oral keratinocytes influence immune signaling and drug responses, highlighting the need to examine host-microbe interactions further for understanding health and disease.

Background: Few large-scale studies have investigated the association between periodontitis and cardiovascular risk estimated by risk assessment models; moreover, this association remains unexplored in never-smokers. We aimed to examine the relationship between periodontitis and cardiovascular risk in a Norwegian general population, with a focus on never-smokers and the impact of sex and age.

Methods: The present study included 2623 participants from the seventh survey of the Tromsø Study (Tromsø7, 2015-2016), aged 45-74 years, and without previous myocardial infarction or stroke.

Twenty-six Swedish dental health care clinics participating in the intervention study "Evaluation of caries preventive measures" have been analysed with focus on costs, with the aim of demonstrating techniques suitable for evaluating direct dental care costs and also finding out whether charges are acceptable as a proxy for real costs. Three different approaches to calculating unit costs are discussed: average treatment time cost and two methods of different allocation of overhead cost. Average treatment time cost shows treatment time cost regardless of who (dentist, dental hygienist or nurse) provides the dental care.
