Background: Propolis is a natural biocompatible material that has been widely studied in dentistry because of its inflammatory, anti-microbial and immunomodulatory properties. One of the active components is caffeic acid phenethyl ester (CAPE). CAPE is effective in stimulating collagen as well as inhibiting the inflammation and degeneration of dental pulp. Purpose: To investigate the post-administration of propolis extract as pulp capping material enhances odontoblast-like cell thickness and type 1 collagen expression in Wistar rats (Rattus Norvegicus) Methods: This research was a true experimental design with a posttest-only control group design. Sixty-three Wistar rats were randomly divided into three groups, with each group consisting of 21 rats: Group I: Positive control; no capping material was administered; Group II: CAPE was administered; Group III: 11% of the propolis extract was administered. All samples were filled with glass ionomer cement. Seven rats from each group were sacrificed after days 7, 14 and 28 of post-pulp capping administration, and their afflicted teeth were subsequently extracted for histologic analysis. Results: No significant difference was seen in odontoblast-like cell thickness after the application of CAPE and propolis on days 7 and 14 (p > 0.05). However, a significant difference was noticed on day 28 (p < 0.05), with the thickness of odontoblast-like cell in CAPE being thinner than that in propolis. A significant difference in the expression of type 1 collagen was observed on days 7, 14 and 28 after the application of the propolis extract compared with CAPE (p < 0.05). Conclusion: The post-administration of propolis extract as a pulp capping material could enhance odontoblast-like cell thickness and type 1 collagen expression in Wistar rats.

Background: One purpose of operative dentistry is the maintenance of healthy pulp by reducing the need for root canal treatment and the possibility of undesirable scenarios such as tooth loss. Propolis is a plant-derived substance that contains a resin produced by honeybees belonging to the Apis mellifera species. Purpose: This study aimed to investigate the effect of a combination of calcium hydroxide (Ca(OH)2) and propolis extract on odontoblast-like cell proliferation in Wistar rats (Rattus norvegicus). Methods: This research constituted a true experimental laboratory-based investigation with post-test control group design. Thirty Wistar rats were randomly divided into six groups. The first molar pulp of each sample was perforated on occlusal surfaces using a low speed round bur. On day 3, the samples were divided into six groups (n=10): Group I: control; Group II: Ca(OH)2 + 11%; propolis extract; Group III: Ca(OH)2 + aquadest, and on day 7: Group IV: control; Group V: Ca(OH)2 + 11% propolis extract; Group VI: Ca(OH)2 + aquadest. All samples were filled with restorative material. They were subsequently sacrificed after 3 and 7 days post-pulp capping administration and the afflicted tooth extracted for hematoxylin and eosin (H&E) staining. The resulting data was subjected to statistical analysis to ascertain the proliferation of odontoblast-like cells. The significance of differences between the groups was determined by a one-way ANOVA test followed by a post hoc Tuckey HSD. A p-value <0.05 was considered to be significant. Results: On day 3, a significant difference existed between group II (Ca(OH)2–propolis) and group I (control group) and group III (Ca(OH)2–aquades), whereas Ca(OH)2–propolis revealed that the proliferation of odontoblast-like cells was higher. Meanwhile, on day 7, there was a significant difference between all groups whereas, with regard to Ca(OH)2–propolis, the proliferation of odontoblast-like cells in group V was higher. Conclusion: Application of combination of Ca(OH)2-propolis extract can increase the proliferation of odontoblast-like cells in pulp tissue on days 3 and 7.

Background : Propolis is a resinous hive product collected by bees ( Apis Mellifera ) from tree buds and mixed with secreted bee wax in order to avoid bacterial contamination in the hive, and also to seal it. Propolis is employed for the treatment of various infectious diseases because it is wellknown that is has antibacterial and anti-inflammatory properties. Calcium hydroxide was introduced to the dental profession in 1921 and has been considered the “gold standard” for direct pulp capping materials   in the past decades. Aims :This research is to investigate the development of new blood vessels ( angiogenesis ) in rat's dental pulp following application of propolis extract and calcium hydroxide. Methods : There was 43 Strain Wistar rats  of 8–16 week old and 200–250 grams in weight were used in this study. The rats were randomly divided into 6 groups. Pulp exposures were performed on the occlusal surface of right maxillary first molars. At the 1st and 4th groups, as the control group, without pulp capping paste. At the 2rd and 5th groups, pulp exposure was applied with propolis extract. And at 3th and 6th groups pulp exposure was applied with calcium hydroxide ,and the 7th group is negative control is a normal teeth. Pulp exposure was applied with propolis extract. After that, all of the cavities were filled with light cured glass ionomer cement as a permanent filling. Animals on the 1st, 2rd, and 3th groups were decaputed after 7x24 hour  post  pulp capping material application and were sent for histological examination which new blood vessels ( angiogenesis )  cells were present. And at the 4th, 5th, 6th groups were culled after 7x 24 hour post  pulp capping material application and were sent for histological examination which new blood vessels ( angiogenesis ) evaluated were present. Result : All sample were histopathological examinated and data was statiscally analysed using one way ANOVA the histological analysis revealed that the development of the new blood vessels  occurred in all group. The new blood vessels ( angiogenesis ) of propolis extract group was milder compared to the control and calcium hydroxide group, with statistical analysis showed significant difference (p > 0.05). Conclusion: The development of new blood vessels is earlier happened in group capping material containing propolis and which show with reduce the amount of the new blood vessels in days 7 and 14 than the other group.

The experiment was conducted on 90 adult healthy Wistar rats. Rats were randomly divided in to 15 equal groups, each of 6 rats, and were kept in separate cages. Group I served as normal healthy control without any treatment, while Group II and III served as vehicle (bicarbonate) control and lithiatic control, respectively. In rats of Group III to IX urolithiasis was induced using 0.75 % (v/v) ethylene glycol and 2% (w/v) ammonium chloride in drinking water for 28 days. The rats of Group I, II, and X to XV were given pure wholesome water till 28 days. After 28th day, the rats of urolithiatic treatment Groups IV, V, VI, VII, VIII and IX were given aqueous and alcoholic extracts of Bryophyllum calycium and Solanum xanthocarpum @ 300 mg/kg bwt orally as either single extract or combination as biherbal extracts in 0.5 % sodium bicarbonate using syringe and rat lavage needle, and so also was done for rats of Group X to XV as extract control groups. Blood samples were collected twice: i.e. on day 28 of induction of urolithiasis and then on day 56 of experiment from all rats. No significant difference was observed in any of the haematological parameters and even in serum albumin and globulin levels before and after treatment in different groups. However, increased levels of serum BUN, uric acid and creatinine were observed in the urolithiatic groups as compared to the normal control group on 28th day. While serum total protein levels were decreased in the calculi induced groups as compared to the normal control group. However, co-treatment of aqueous or alcoholic extract of Bryophyllum calycinum and Solanum xanthocarpum significantly restored these changes by 56th day. The effect of biherbal alcoholic extract of the plants was much better in restoring the values and the levels came nearer to normal by 56th day of oral treatment proving nephroprotective effect of these extracts.

Objectives: The aim of this pilot study was to evaluate the antibacterial activity of glass ionomer cement impregnated with different concentrations (0.5%, 1.25% and 2.5%) of a non releasing bactericide –Triclosan (TC) against two common cariogenic bacteria – Lactobacillus acidophilus and Streptococcus mutans; and to compare Triclosan incorporated GIC with chlorhexidine (CHX) incorporated GIC (2.5%)in terms of antibacterial activity. Methods: Chlorhexidine or Triclosan were added to glass ionomer cement powder to achieve 2.5% CHX – GIC (positive control – Group II), 0.5%, 1.25% and 2.5% TC-GIC (experimental groups III, IV and V respectively) formulations. Restorative glass ionomer cement (Fuji IX GC –Group I) served as negative control. The powder and liquid were mixed and inserted into the wells punched in agar plates (10mm × 4mm). The agar diffusion method was used to determine the antibacterial activity of the cements after 1, 7 and 30 days. Mean values were compared between different study groups using One-way ANOVA and Tukey's HSD procedure at a significance level of 5%. Results: Triclosan incorporated GIC was more effective against L.acidophilus and S.mutans than Chlorhexidine incorporated GIC. Triclosan at a concentration of 2.5% was more effective than at lower concentrations. At all time periods studied, the maximum zone of inhibition against L.acidophilus was produced by Group V. Against S.mutans, on days 1,7 and 30, there was no significant difference between Groups II and IV (p&gt;0.05), while the other groups showed significant differences. Conclusion: The use of triclosan as an antibacterial additive in GIC holds promise and further clinical research is needed in this direction.

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.

The aim of this experiment was to determine the effect of meniran herbs (Phyllantus niruri L.) extract to blood triglycerides level in Wistar rats (Rattus norvegicus). This experiment was a laboratory experiment with pre and post-test with a control group design. The samples were 30 male Wistar rats with ±200 gram of body weight and ±2 months old. The samples were divided into five groups by using a purposive random sampling technique and each group consisted of six rats. Group I as a negative control, group II as a positive control, and groups III, IV and V as meniran herbs extract groups with first dose, second dose, and third dose. All rats were simultaneously given with hyperlipemic feed. Group II was simultaneously administered with Cholvastin 0.5 mg/200 grams body weight/day. Groups III, IV and V were simultaneously treated with meniran herbs extract at dose of 25 mg, 50 mg and 100 mg/200 grams body weight/day. The total period of this experiment was 21 days. At the day 1st and 21st, blood was collected from rat orbital venous plexus. Serum was analyzed for their pre and post-test blood triglycerides. Statistical analysis was performed by one-way analysis of variance (ANOVA) followed by a post-hoc test. The value of p=0.002 (p<0.05) showed there was a significant difference between pre-test and post-test in delta means of blood triglycerides level among groups. Meniran herbs extract had a significant triglycerides lowering effect against blood triglycerides level of Wistar rats. The most potential of meniran herbs extract dose was 100 mg/200 gram body weight/day.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17).
