Limpet Teeth as Bio Fillers in Dental Composite Resin

The Extreme mechanical properties shown by limpet radula can be used as a biofiller to improve the mechanical properties of composite resin. The aim of the research is to develop and analyze the mechanical properties of a silanized limpet radula as a biofiller in an experimental composite resin. The objective is to compare the compressive, tensile and flexural strength of the experimental composite resin with biofiller and the Universal Hybrid Composite resin. Littoraria scabra species have been selected and the tongue-like radula was extracted from the buccal mass under an optical microscope. Based on previous research, an experimental dental composite resin with 2.5% radula as silanized biofiller was created, and SEM analysis was performed to confirm the filler morphology. The samples were prepared in accordance with ISO 4049, and 15 samples from each group were randomly subdivided into three subgroups to assess compressive, tensile, and flexural strength. The Shapiro-Wilk and independent t-tests were used for statistical analysis. The experimental composite resin with the bio-filler had relatively high compressive, tensile, and flexural strength when compared to universal hybrid composite resin. Within the scope of the study, it is feasible to conclude that the addition of 2.5% silanized limpet radula as a biofiller in the experimental composite resin improves mechanical properties over the Universal Hybrid Composite.
