Abstract: Eggshell is one of the natural wastes which if not treated properly can cause environ- mental pollution. Broiler eggshells consist mostly of CaCO3 (calcium carbonate) that can be synthesized into CaO (calcium oxide) then be processed into Ca (calcium). Calcium has a function to fill the density of bones and teeth that affects their strength and hardness. This study aimed to determine the effect of soaking in broiler chicken eggshell solution on the hardness of tooth enamel. This was an experimental laboratory study with a posttest only control group design. Samples were 24 maxillary first premolar obtained from dental clinics, public health centers, and hospitals in Semarang, Indonesia. Samples were divided into four groups: control group and treatment groups 1, 2, and 3 (duration of soaking in eggshell solution for 2, 7, and 14 days. respectively). The one way ANOVA test resulted in a p-value of 0.000 which meant that there were significant differences in the four groups. The post hoc test showed a p-value of <0.05, which meant that there was a significant difference between the control group (artificial saliva) and the treatment groups of 2.7 and 14 days. In conclusion, chicken eggshell solution has an effect on increasing the hardness of tooth enamel.
