Aim and objective: To develop and analyze the mechanical properties of a silanized limpet radula as a bio-filler in an experimental composite resin. The objective is to compare the compressive, tensile, and flexural strength of the experimental composite resin with bio-filler and the Universal Hybrid Composite resin.
Materials and methods: Littoraria scabra species have been selected and used in the study. The tongue-like radula was extracted from the buccal mass under an optical microscope. The radula was then subjected to SEM and EDX analysis. The experimental dental composite resin with 2.5% of radula as silanized bio-filler was prepared based on previous studies and SEM analysis was done to verify the filler morphology. The experimental composite resin was compared with the Universal Hybrid Composite resin. Based on ISO 4049, the samples were prepared and 15 samples from each group were then randomly subdivided into three subgroups to analyze the compressive, tensile, and flexural strength.
Results: Statistical analysis were conducted using the Shapiro-Wilk and an independent t-test. Compared to universal hybrid composite resin, the experimental composite resin with the bio-filler had relatively high compressive, tensile, and flexural strength.
Conclusion: Within the limitations of the analysis, it can be concluded that the addition of 2.5% of silanized limpet radula as bio-filler in experimental composite resin has improved mechanical properties than the Universal Hybrid Composite.
Clinical significance: The extreme mechanical properties shown by limpet radula can be used as a bio-filler to improve the mechanical properties of composite resin.
