The effect of Er:YAG laser irradiation with different frequencies on surface decontamination of used healing abutments: a supplementary approach to sterilization.

Reusing healing abutments is common practice among clinicians; however, ensuring complete surface decontamination is crucial to avoid further complications. This study aimed to evaluate the cleaning potential of Er: YAG laser at different frequencies, as an adjunctive step prior to autoclave sterilization. Forty contaminated healing abutments were divided into four groups.

Body size and occupational physical activity during the life course and gastrointestinal cancers.

Evidence on the associations of body size and occupational physical activity (PA) during the life course with gastrointestinal cancers is inconclusive. We analyzed data from the Golestan Cohort Study, a population-based prospective cohort study from Iran, with 50,045 individuals aged 40-75 years enrolled during 2004-2008 and followed through April 2023. Body size during adolescence, early adulthood, and at cohort baseline was assessed using validated pictograms.

Investigating the Effect of Photobiomodulation Therapy With Different Wavelengths of Diode Lasers on the Proliferation and Adhesion of Human Gingival Fibroblast Cells to a Collagen Membrane: An In Vitro Study.

Photobiomodulation (PBM) is considered a promising adjunctive approach in regenerative medicine. This study aimed to investigate the proliferation and adhesion of human gingival fibroblast (HGF) cells to a collagen membrane following PBM. Cultured HGF cells on a collagen membrane received PBM at wavelengths of 808 nm, 915 nm (2 and 4 J/cm), and 660 nm (2.

Which dietary patterns fend off nonalcoholic fatty liver disease? A systematic review of observational and interventional studies.

Background: The global burden of non-alcoholic fatty liver disease (NAFLD) has significantly risen over the past decade. Dietary intake strongly influences its development and should be a component of any prevention and treatment plan strategy. Dietary pattern analysis enables the investigation of the overall diet and permits the consideration of interactions and cumulative effects of dietary components.

In Vitro Effect of Photodynamic Therapy With Curcumin in Combination With Photobiomodulation Therapy by 660 nm on the Viability of Human Gingival Fibroblasts.

This study aimed to assess the effect of repeated irradiations of 660 nm photobiomodulation therapy (PBMT) after photodynamic therapy (PDT) with curcumin on the viability of human gingival fibroblasts (HGFs). In this in vitro, experimental study, HGFs were cultured and assigned to five groups: One control group with no intervention and four experimental groups of PDT with curcumin, PBMT (660 nm laser irradiation) immediately after PDT, PBMT immediately and 24 hours after PDT and PBMT immediately and 24 hours and 48 hours after PDT. Cell viability was assessed after 1, 4, and 7 days using the methyl thiazolyl tetrazolium (MTT) assay.
