Background: A novel approach to enhancing the mechanical properties of glass-ionomer cement (GIC) may incorporate natural fiber. This study aims to evaluate the effects of raw and pure hemp fiber additions on the flexural strength (FS) and surface roughness (SR) properties of glass-ionomer cement (GIC).
Methods: Hemp fibers sourced from the local population were harvested, dried, and separated, then prepared in raw and pure forms to assess their impact on the FS and surface roughness of GIC. Synthesized GICs dopped raw and pure hemp fiber were characterized using SEM and EDX for morphological and elemental analysis. The mechanical features of GICs were measured using an FS and SR testing apparatus.
Results: Raw hemp fibers, known for their sustainability and mechanical resilience, showed significant enhancements in FS, particularly at 1% addition. High FS and SR values using pure fibers at 1% and 3% concentrations were due to improving fiber-matrix interactions, reducing the cracks on GICs. SEM analysis of fracture surfaces supported these findings, showing fiber reinforcement at crack lines.
Conclusion: This approach offers a promising, eco-friendly, cost-effective alternative for dental restorations, combining mechanical durability and surface quality. These results highlight the potential of hemp fiber-reinforced GIC in advancing sustainable, restorative materials in dentistry.

Objectives: This study aimed to assess the impact of incorporating glass ionomer fillers of varying sizes on fluoride release, antiplaque properties, and the abrasive effects of toothpaste.
Materials And Methods: In this laboratory study, three toothpaste samples containing glass ionomer filler particles (0.5, 5 µm, and a hybrid combination of equal proportions of both fillers) were tested, along with a base toothpaste without fillers or fluoride and a commercial toothpaste (Colgate Total) as controls.

Objective: Understanding the sealing ability of restorative materials to prevent microleakage and its consequent complications-such as secondary caries, postoperative sensitivity, and restoration failure-is imperative in clinical dentistry. This study aims to compare the microleakage performance of four restorative materials-bioactive composite resin (Activa Pronto), alkasite restorative (Cention N), compomer (Dyract Flow), and glass ionomer cement (Type 2 GIC)-in Class V cavities of extracted premolar teeth.
Materials And Methods: Forty non-carious, intact premolar teeth were selected and prepared with standardized Class V cavities.
