Result: The experiment shows the existence of colour changing after the immersion process in 100% green kiwi juice (Actinidia deliciosa) with significant result or significantly different of (colour’s changing total) is about (p≤0,05) before and after the test. Here, the samples are brighter after the immersion inside green kiwi juice (Actinidia deliciosa) with increasing value (lightness). Conclusion: Green kiwi fruit (Actinidia deliciosa) is a potentially material for dental bleaching as the effect of external dischloration.
