This study aims to evaluate the effect of variations in the composition of snail shell powder (Achatina fulica) and blood cockle shell (Anadara granosa) on the hardness and wear of dental filler materials. Snail shell waste rich in calcium carbonate (CaCO3) was calcined at 800°C for 5 hours to produce calcium oxide (CaO). The calcined powder was mixed with polyacrylic liquid in certain compositions and tested using the Vickers Microhardness Tester method and SEM-EDX for morphological characterization and elemental contents on both shells. The results showed that variations in percentage of the composition of snail shell powder and blood cockle affected the mechanical properties of the implant material. The pure composition of snail shell (100%) produced the highest hardness with an average value of 76.7 kgf/mm2, while the pure mixture of blood cockle shell (100%) had the lowest hardness of 62.07 kgf/mm2. Any others composition have hardness in between the two values. The SEM-EDX test showed that the dominant elements in both materials were oxygen (O) of 54-59%, calcium (Ca) of 23-29%, and carbon (C) of 15-17%, which supported the calcium carbonate-based structure. This study reveals the potential for innovation in dental filler materials based on sustainable biomaterial waste and has adjustable mechanical performance. ©Published under licence by IOP Publishing Ltd.
