Macrophages are the cells that most appear when inflammation occurs. Treatment for maintaining pulp tissue vitality is called pulp capping. Calcium hydroxide as a pulp capping material has the ability to trigger the growth of dentin bridges or remineralization, but calcium hydroxide can induce migration and proliferation of inflammatory cells. Currently the field of dentistry is developing propolis as an alternative pulp capping material. That is because propolis has anti-inflammatory properties. Purpose: To analyze the effect of the combination of calcium hydroxide-propolis on the number of macrophage cells in the teeth of Wistar rats with pulp perforation. Methods: This study used 30 samples of Wistar rats which were preparate until perforation and then divided into 3 groups. The first group continued with filling wit...

Pain in inflammation is induced by the cyclooxygenase-2 enzyme (COX-2) which induces prostaglandin E2 (PGE2) resulting in pain. Pain in the pulp can be relieved by eugenol. In its application, eugenol is toxic to pulp fibroblasts. Due to the side effect, it is worth considering other biocompatible materials with minimal side effects, such as propolis. Flavonoids and phenolic acids that contained in propolis can inhibit COX-2. Therefore, an analysis outlined in the literature review is needed to examine the results of research related to the role of propolis as pulp pain relief by inhibiting COX-2 expression. Purpose: To analyze the role of propolis in pulp pain by inhibiting COX-2 expression. Reviews: Propolis extract that extracted by ethanol, water, and hydroalcohol has pain relief properties in the pulp by inhibiting COX-2 by directly binding to the COX-2 receptors and by reducing the production of proinflammatory cyto...

One of the restorative materials closer to natural teeth is composite resin because it is the same colour as natural teeth and is easy to shape. As for the placement technique, bulkfill is also used because it is more time-efficient, and irradiation is accompanied by applying the restoration material in one batch. However, the bulkfill technique often causes micro-leakage of dental caries deposition. The intermediate layer is an intermediate layer used to prevent micro-leakage at the edges of the restoration as a base layer for restoration to create a good adaptation before applying packable composite resin. Therefore, bulkfill coating technique with the intermediate layer can reduce the risk of microleakage. Purpose: To describe the bulkfill technique with an intermediate layer against marginal ad...

Odontoblasts situated at the pulp dentin interface are the frst cells encountered by these bacteria and have an important role in this response. Lipoteichoic acid (LTA), a wall component of Gram-positive bacteria, triggered the activation of the odontoblasts. LTA upregulated the expression of its own receptor TLR2, as well as the production of proinflammatory cytokineTNFα. Propolis is a resinous material that holds a great potential as an antiinflammatory agent. Present studies have shown that propolis has a reduction effect towards the proinflammatory cytokines expression and favor pulp healing.Purpose: To reveal the moleculer mechanism of propolis stimulation onodontoblast like cells, induced by inactive Lactobacillus acidophilus.Methods: This review was presented in odontoblasts like cells culture i...

Pulp capping by calcium hydroxide could causing tissue necrosis followed by inflammation. Calcium hydroxide combined with propolis which have anti-inflammatory effects through inhibition of the Nf-kB pathway and pro-inflammatory cytokines. That process will inhibit the increase of vascular permeability and neutrophil chemotaxis. Inflammatory process can accelerate by controlling the amount of neutrophil cells as a acute phase marker, so the healing process occurs more quickly. Therefore it is necessary to study the amount of neutrophil cells in the pulp perforation of Wistar rats after applicated by combination of calcium hydroxide-propolis. Purpose: To analyze the difference amount of neutrophil cells on the Wistar rats pulp perforation after applicated by calcium hydroxide-propolis combination compared with calcium hydroxide-aquadest Method: M1 tooth perforated for all groups ...
