Nicotine-related misperceptions among faculty and students at a Midwestern dental school.

Purpose/objectives: To determine the perceptions about the ill-effects of nicotine in students and faculty at a Midwestern dental school. This information will help inform the school and improve teaching on this subject during a time when electronic nicotine delivery systems are increasingly popular.

Methods: An online survey of dental students and faculty of a Midwestern dental school was deployed in November, 2020 to determine their level of misperception about the ill effects of nicotine.

An activated-zinc oral rinse reduces pro-inflammatory cytokine secretion and promotes proliferation in Porphyromonas gingivalis LPS-challenged gingival tissues - A pilot study.

Objectives: The use of adjunct post-treatment mouth rinses containing chlorhexidine (CHX) for periodontitis patients is associated with side effects that reduce patient compliance. Our aim was to evaluate the proinflammatory and cell proliferation effects of an activated-zinc mouth rinse (SM) that has been suggested as an alternative post-treatment therapeutic.

Materials And Methods: Tissue models of gingival epithelium were used to simulate periodontal disease and compare inflammatory reactions after treatment with CHX or SM.

Phylum Synergistetes in the oral cavity: A possible contributor to periodontal disease.

Microbial contributions to periodontal disease have been under renewed scrutiny with the advent of newer technologies to identify their presence and gene expression at the molecular level. Members of the phylum Synergistetes are some of the more recent bacteria to be associated with periodontal disease. Bacteria classified in this phylum can be found in a wide variety of habitats including both inside and outside of a mammalian host.

Diet modulates proteinuria in heterozygous female dogs with X-linked hereditary nephropathy.

Young adult heterozygous (carrier) female dogs with X-linked hereditary nephropathy (XLHN) have glomerular proteinuria but are otherwise healthy. Because data regarding dietary influences on the magnitude of proteinuria in dogs with spontaneous glomerular disease are not available, 12 such dogs were studied in a double crossover experiment intended to determine effects of altering dietary protein intake for up to 6 weeks. Dogs were blocked by urine protein : creatinine ratio (UPC) and randomly assigned to receive 2 diets: high protein (34.
