Background: Dental restorative materials, especially those applied in direct contact with the contaminated substrate, should have appropriate antibacterial activity in order to prevent residual bacteria from continuing their metabolic activity in addition to impairing new bacteria from reaching the tooth-restoration interface.
Aim: To determine the antibacterial efficacy of three different restorative materials against the common cariogenic microorganism i.e., Streptococcus mutans.
Materials And Methods: Three different restorative materials were evaluated in this study: Giomer (Beautifil), Compomer (F2000) & Resin modified Glass ionomer (Fuji II LC) for their anti microbial efficacy against Streptococcus mutans by standard agar diffusion method and zones of inhibition for each restorative material were calculated.
Statistical Analysis: Inhibition zones around each restorative material were measured and values were subjected to one-way ANOVA with least square difference (LSD) Post-hoc test.
Results: The mean inhibitory zones for Resin modified glass ionomers, Giomers & Compomers ranged from 10.1 - 6.90mm. Fuji II LC exhibited the highest mean inhibitory zone of 10.1 ± 1.97 for S.mutans. Beautifil exhibited mean inhibitory zone of 8.20 ± 1.62, whereas F2000 showed the least mean inhibitory zone of 6.90 ± 1.29.
Conclusion: Based on the inhibitory zones of three restorative materials, Fuji II LC is recommended as the best restorative material among the three tested restorative materials.

Background: Obesity and circadian rhythm disruption are significant global health concerns, contributing to an increased risk of metabolic disorders. Both adipose tissue and circadian rhythms play critical roles in maintaining energy homeostasis, and their dysfunction is closely linked to obesity. This study aimed to assess the effects of chronic low-dose SR9009, a REV-ERB ligand, on circadian disruption induced by constant light exposure in mice.

Wounds are one of the most critical clinical issues in plastic surgery repair and restoration. Conventional wound dressing materials cannot absorb enough wound exudates and shield the site from microbial infection. Also, despite their healing prowess, bioactive molecules from medicinal plants are less bioavailable at the wound sites.

Metallic zinc (Zn) has been demonstrated to be a promising alternative to barrier membrane materials for guided bone regeneration. Surface roughness significantly affects the properties of degradable Zn-based metals, especially within the Janus micro-environments of tissue regeneration. However, the effects of optimal surface roughness on Zn remain unknown.
