Summary Introduction Direct pulp capping is an important therapeutic method that has goal to provide formation of dentin bridge and healing process of the pulp. The aim of this study was to investigate the effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite on exposed dental pulp in Vietnamese pigs. Material and Methods The study was conducted on 30 teeth of two Vietnamese pigs (Sus scrofa verus). On buccal surfaces of incisors, canines and first premolars, class V cavities were prepared with a small round bur and pulp horn was exposed. In the first experimental group (10 teeth) the perforation was covered with new nanostructural material based on calcium silicate systems (CS). In the second experimental group, the perforation was covered with compound of calcium silicate systems and hydroxyapatite (HA-CS) (10 teeth). In the control group, exposed pulp was covered with Pro Root MTA® (Dentsply Tulsa Dental, Johnson City, TN, USA) (10 teeth). All cavities were restored with glass ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). Observation period was 28 days. After sacrificing the animals, histological preparations were done to analyze the presence of dentin bridge, inflammatory reaction of the pulp, pulp tissue reorganization and the presence of bacteria. Results Dentin bridge was observed in all teeth (experimental and control groups). Inflammation of the pulp was mild to moderate in all groups. Neoangiogenesis and many odontoblast like cells responsible for dentin bridge formation were detected. Necrosis was not observed in any case, neither the presence of Gram-positive bacteria in the pulp. Conclusion Histological analysis indicated favorable therapeutic effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite for direct pulp capping in teeth of Vietnamese pigs.

This study was conducted to observe the response of dogs' dental pulp to white mineral trioxide aggregate (MTA) when used as pulp capping material. The pulp of 15 dogs' teeth was experimentally exposed and capped with white MTA. The animals were sacrificed two months later and the specimens were prepared for histomorphological study. The pulp capped with white MTA showed a healing process with complete dentin bridge formation in all samples. In some cases, there was not a tubular dentin shape, but only a structure with an interesting morphological aspect sealing the exposure site. Only 2 specimens exhibited pulp inflammation. In conclusion, the data obtained in this study showed that white MTA has the necessary properties of a pulp capping material.

Introduction. Direct pulp capping procedure is a therapeutic application of a drug on exposed tooth pulp in order to ensure the closure of the pulp chamber and to allow the healing process to take place. Objective. The aim of this study was to examine the histological effects of Emdogain? on exposed tooth pulp of a Vietnamese pig (Sus scrofa verus). Methods. The study comprised 20 teeth of a Vietnamese pig. After class V preparation on the buccal surfaces of incisors, canines and first premolars, pulp was exposed. In the experimental group, the perforations were capped with Emdogain? (Straumann, Basel, Switzerland), while in the control group pulp capping was performed with MTA? (Dentsply Tulsa Dental, Johnson City, TN, USA). All cavities were restored with glass-ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). The observational period was 28 days, after which the animal was sacrificed and histological preparations were made. A light microscope was used to analyze dentin bridge formation, tissue reorganization and inflammation, and the presence of bacteria in the pulp. Results. The formation of dentin bridge was observed in the experimental and control groups. Inflammation of the pulp was mild to moderate in both groups. Angiogenesis and many odontoblast-like cells, responsible for dentin bridge formation, were observed. Necrosis was not observed in any case, nor were bacteria present in the pulp. Conclusion. Histological analysis indicated a favorable therapeutic effect of Emdogain? Gel in direct pulp capping of Vietnamese pigs. Pulp reaction was similar to that of MTA?.

The Difference

Background: Pulp inflammation can be treated with pulp capping by calcium hydroxide as the gold standard. 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 with three types tratment: no medication (control group), calcium hydroxide-aquadest 1: 1 (P-1 group), and calcium hydroxide-propolis 1: 1.5 (P-2 group) and closed with cention. Observations were made on the 1st, and 3rd day with HE staining. Results: One Way ANOVA shown a significant difference (p <0.05) of the average amount of neutrophil cells between all treatment groups on 1st day (p=0,000) and 3rd day (p=0,000). The amount of neutrophil cells in the calcium hydroxide-propolis (P-2) combination group was lower than control group and calcium hydroxide-aquadest (P-1) group on the 1st and 3rd day. Conclusion: The amount of neutrophil cells after application of calcium hydroxide-propolis is lower than calcium hydroxide-aquadest application.
