Handling traumatic ulcer use corticosteroids that have the effect of increase the growth of Candida sp. in the oral cavity (candidiasis). Objective: To determine the effect of Java chili extract (Piper retrofractum Vahl.) on leukocyte reduction in Wistar rats with traumatic ulcer. Methods: This is experimental laboratory study with pre and post test with a control group design. The research sample using 20 male Wistar rats, weight ±150 grams, 2-3 months old, divided into 4 treatment groups, (K1) group with untreated ulcers, (K2) rats with ulcers treated with iodine, (K3) rats with ulcers treated with java chili extract 50%, (K4) rats with ulcers treated with java chili extract 100%.The research was analyzed by different test with dependent sample t test. Results: The results showed a value of p <0.05 for all comparisons between the two groups showed that there were differences between the two groups compared have a significant difference in the number of leukocytes so it was known that Java chili extract decreased the number of leukocytes in Wistar rats with traumatic ulcers. Conclusion: Java chili extract (Piper retrofractum Vahl.) was effective in decreased the number of leukocytes in Wistar rats with traumatic ulcers.]]>
