Saliva contains antimicrobial peptides considered integral components of host innate immunity, and crucial for protection against colonizing microbial species. Most notable is histatin-5 which is exclusively produced in salivary glands with uniquely potent antifungal activity against the opportunistic pathogen Candida albicans. Recently, SARS-CoV-2 was shown to replicate in salivary gland acinar cells eliciting local immune cell activation.

Candida auris is an emerging nosocomial fungal pathogen associated with life-threatening invasive disease due to its persistent colonization, high level of transmissibility and multi-drug resistance. Aggregative and non-aggregative growth phenotypes for C. auris strains with different biofilm forming abilities, drug susceptibilities and virulence characteristics have been described.

Article Synopsis
  • The oral cavity has been overlooked as a potential infection site for SARS-CoV-2, with recent findings showing the virus can replicate in salivary gland cells and cause inflammation.
  • A study comparing hospitalized COVID-19 patients to healthy controls revealed significant reductions in bacterial and viral diversity in the mouths of infected individuals, with specific bacterial species linked to COVID-19 status.
  • Notably, the opportunistic fungal pathogen associated with oral candidiasis was found in about half of the COVID-19 patients, suggesting a connection between the virus and disruptions in oral health, highlighting the need for further research on this relationship.

is an emerging nosocomial fungal pathogen associated with life-threatening invasive disease due to its persistent colonization, high level of transmissibility and multi-drug resistance. Aggregative and non-aggregative growth phenotypes for strains with different biofilm forming abilities, drug susceptibilities and virulence characteristics have been described. Using comprehensive transcriptional analysis we identified key cell surface adhesins that were highly upregulated in the aggregative phenotype during and grown biofilms using a mouse model of catheter infection.

Objectives: To investigate the effect of fluoride and silver nanoparticles on the prevention of in vitro demineralization of sound enamel and enamel caries-like lesions of varying severities.

Methods: Caries-like lesions of different severities (1/6/15 days) were created in bovine enamel specimens. One group remained sound.

Article Synopsis
  • Candida albicans is associated with denture stomatitis, and while nicotine exposure worsens this issue, caffeine may inhibit the yeast's growth, but their combined effects are unclear.
  • The study aimed to assess how caffeine affects the metabolic activity and biofilm formation of C. albicans on acrylic denture resin in the presence of nicotine, exploring varying concentrations of caffeine.
  • Results indicated that 8 mg/mL of nicotine enhanced both the metabolic activity and biofilm attachment of C. albicans, suggesting a complex interaction between these substances.

Objective: To evaluate the medical and dental health status of orphan children from 4 to 12-years-old, and compare them with children living with their parents.

Methods: This analytical, cross-sectional study took place in 3 government orphanages and 3 ordinary schools in Riyadh, Saudi Arabia from July 2011 to January 2012. All orphans aged 4-12 year were selected (N=90).
