Objectives: This study aimed to evaluate the release of calcium ions from a bioactive restorative material and its shear bond strength (SBS) to primary dentin.
Study Design: Occlusal surface of extracted non-carious primary molars were flattened, onto which 2 × 2 mm cylinders of ACTIVA™ BioActive Restorative (PULPDENT® Corporation, Watertown MA) or Fuji II LC (GC Corporation, Tokyo, Japan) were prepared using a polypropylene straw mould. SBS of the materials to primary dentin was tested using a universal testing machine. The mode of bond failure was assessed using stereomicroscopy. 10 mm × 2 mm disks of each material were prepared and immersed in Milli-Q water for 1, 7, 14 and 21 days. The released calcium ions in the immersion media were quantified using Atomic Absorption Spectroscopy.
Results: ACTIVA™ BioActive Restorative showed a mean SBS of 4.29 ± 0.65 MPa to primary dentin and calcium ion release of 0.76 ± 0.12 ppm over 21 days.
Conclusion: ACTIVA™ BioActive Restorative showed a significantly higher mean SBS to primary dentin, and significantly higher calcium ion release compared to Fuji II LC.

Aims: This study aimed to evaluate the enamel remineralization effect of fluoride-incorporated bioactive glass (F-BG) toothpaste on artificial subsurface caries in primary teeth.
Materials And Methods: Forty sound primary maxillary incisors were subjected to a demineralizing solution for four days to induce artificial enamel caries. The teeth were randomly divided into four experimental groups ( = 10 per group): Group I, F-BG toothpaste (530 ppm fluoride) (BiominF); Group II, 0.

Background: Importance of fluoride in dental restorative materials for preventing secondary caries. Several commercially available tooth-colored dental restorative materials, such as glass ionomer cement, resin composites, and compomers were used for this study.
Aim: To evaluate the amount of fluoride release from tooth-colored restorative materials [Conventional Glass Ionomer Cement (GC Fuji II)], Resin-modified Glass Ionomer Cement (ACTIVA BioACTIVE-RESTORATIVE), and Giomer (BEAUTIFIL II LS)] using ion-selective electrode (ISE) and spectrophotometer using zirconyl alizarin red dye method.

Synthetic antidiabetic drugs are often associated with various adverse side effects, including hypoglycemia, nausea, gastrointestinal disturbances, headaches, and even liver damage. In contrast, plant-derived natural antidiabetic bioactive compounds typically exhibit lower toxicity and fewer side effects and have been reported to aid effectively in diabetes management. These plant extracts regulate diabetes by restoring pancreatic function, enhancing insulin secretion, inhibiting intestinal glucose absorption, and facilitating insulin dependent metabolism.

Inhibition of jasmonic acid (JA) signaling renders plants more susceptible to biotic stresses. Pathogen infection can induce an increase in JA levels. However, our understanding of the mechanisms mediating pathogen-induced JA accumulation in rice (Oryza sativa) remains limited.
