摘要
Inflammation in pulp tissue is caused by caries bacteria. Most bacteria found are Lactobacillus acidophilus. Propolis is a sticky resin material that is derived from the bees and the surrounding plants, which are reported to have several biological effects including anti-bacterial and anti-inflammatory. This study will prove the effectiveness of propolis against proinflammatory cytokines on odontoblast-like cells in human dental pulp. This study was performed on cultured odontoblast-like cells in pulp. Cell culture was derived from the pulp tissue of human M3 teeth that had been extracted. Odontoblast pulp culture was divided in three groups： group one, cultured cells with propolis; group two, cultured cells induced with inactive Lactobacillus acidophilus; group three, cultured cells induced with inactive Lactobacillus acidophilus and exposed to 3 μg/mL propolis. A measurement of TNF-α and TGF-β1 expression was done using the immunocytochemical technique to determine the effectiveness of propolis extracts from East Java Indonesia against proinfalmmatory cytokines. Data were analyzed using the analysis of variance （ANOVA） test （P = 0.05）. Propolis extract can inhibit the expression of TNF-α and increase the expression of TGF-β1 on odontoblast-like cell in human dental pulp. Anti-inflammatory effects of East Java propolis extract are associated with cytokine modulation.
