Abstract

Background: The prevalence of dental caries in Indonesia in 2018 is 45.3% of the population. Tooth filling is done so that dental caries does not spread further. The restorative material that is commonly used is composite resin. The compressive strength of composite resin is affected by the polymerization process. The surface of the composite resin exposed to air causes the formation of oxygen inhibited layer (OIL). Glycerin acts as a surface coating that can inhibit contact between the composite resin and air so that polymerization can run optimally. Changes in the mechanical properties of composite resins are also influenced by salivary pH and food intake. The acid contained in fermented milk can affect the matrix and filler bonds in composite resins. Further research is needed to determine the compressive strength of nanohybrid composite resins after the application of glycerin in fermented milk immersion. Purpose: To find out whether there is a change in the compressive strength of nanohybrid composite resin after the application of glycerin immersed in fermented milk, also to find out whether the glycerin application and immersion in fermented milk play a role in causing changes of the compressive strength. Methods: Laboratory experimental research with a total sample of 28 which was divided into 4 groups. Composite resin samples were made with a thickness of 3 mm and a diameter of 5 mm, followed by measuring the compressive strength using the Universal Testing Machine. Results: Independent T-Test test showed significantly different results. The compressive strength value of the group with glycerin application was higher than without glycerin application. Meanwhile, the group immersed in fermented milk drinks had lower compressive strength compared to saline immersion. Conclusion: The compressive strength of the nanohybrid composite resin changed after the application of glycerin immersed in fermented milk.

Abstract

Background: Odontogenic pain has a high prevalence where this pain is the result of noxious physical stimuli or calming inflammatory mediators that stimulate receptors located at the terminal ends of nociceptive C and Aδ afferent nerve fibers. Nano propolis is an alternative material that is used as a medicine in dentistry. Nano propolis is a mixture of natural resins containing flavonoids and phenolic acids which play a role in suppressing pain response through COX and NF-kB inhibition mechanisms. Nanoparticle technology is capable of preparing active drug ingredients in nano-sized particles and can affect drug effectiveness, because particle size affects the process of solubility, absorption and distribution of drugs. Research on the potential of nano propolis as an anti-pain is still minimal, so further research is needed on the function of nano propolis as an alternative anti-pain agent. Purpose: To determine the effective dose of nano propolis on pain response in Mus musculus. Methods: This research was conducted using the writhing test method to see the analgesic effect of nano propolis. The research sample consisted of 28 Mus musculus which were divided into four treatment groups, namely the piroxicam control group, and the nano propolis treatment group of 17.5 mg/kg, 35 mg/kg, and 70 mg/kg. Results: The results showed that the four treatment groups did not have a significant difference, in other words, they had the same anti-pain effect. Conclusion: Nano propolis 35 mg/kgBB is an effective dose in suppressing pain response in Mus musculus.

Abstract

Background: Dental caries is a very common non-communicablae disease found in all age groups and found in 3.5 billion people in the world. Caries that harm the pulp tissue can be treated by direct or indirect pulp capping. One of the physical properties possessed by pulp capping is the porosity of material. The material most often used for pulp capping treatment of pulp perforations is calcium hydroxide (Ca(OH) 2 ). However, Ca(OH) 2 has a high pH that caused the porosity to be low. High porosity can facilitate cell development and ion exchange. Thus, additional materials with a lower pH are needed to increase porosity such as Epigallocatechin-3-gallate (EGCG). However, the porosity of the combination of EGCG with Ca(OH) 2 is still unclear, so it needs to be researched. Purpose: To explain the differences of Ca(OH) 2 porosity after the addition of EGCG. Methods: This study used a laboratory experimental study with a post test only control group design. This research using 16 samples for each control (Ca(OH) 2 – aquadest) and treatment (Ca(OH) 2 –EGCG) group. Samples from each group were subjected to freeze drying, observed with SEM, analyzed with ImageJ software, and tested with independent T-test. Results: There was a significant difference (p<0.05) in the percentage of porosity between the addition of EGCG to Ca(OH) 2 namely 32,61% compared to Ca(OH) 2 with aquadest namely 23,38%. Conclusion: The porosity of the combination of calcium hydroxide with EGCG has a higher percentage compared to calcium hydroxide with aquadest.

Abstract

Background: Calcium hydroxide (Ca(OH)2) is the gold standar in pulp capping treatment because the biocompatibility and capability to stimulate hard tissue formation and also antibacterial effect. However, this compound has the disadvantage of being easily soluble in saliva which will increase the risk of leakage in the cavity. Another alternative pulp capping material is calcium carbonate from blood clam shells. Blood clam shells contain 98% CaCO3, CaCO3 has low solubility and is difficult to dissolve in water due to the large ions on Ca2+ and CO32- so that the attractive force between these ions is very strong and finally H2O is not able to break down the CaCO3 compound to be dissolved. Purpose: Explained the differences in the solubility of calcium carbonate from blood clam shells and calcium hydroxide as candidates pulp capping materials. Methods: This research is a laboratory experimental study with a pretest-posttest control group design method. The samples consisted of 12 pieces of Ca(OH)2 and CaCO3 then divided into 2 groups and given treatment. Group 1 CaCO3 immersed in 1 day, group 2 Ca(OH)2 immersed in 1 day, group 3 CaCO3 immersed in 7 days, and group 4 Ca(OH)2 immersed in 7 days. Solubility is calculated according to the solubility formula. Data testing with Anova-Welch. Results: There was a significanly difference in the solubility rate between the CaCO3 dan Ca(OH)2 groups immersed for 1 day and 7 days on the Anova-Welch results (p<0.05). Conclusion: The solubility of CaCO3 in blood clam shells is lower than the solubility in Ca(OH)2.)

Abstract

Background: Deep caries, cavity preparation and use of burs or other dental instruments often result in pulpal perforation. In the case of an exposed pulp, regenerative pulp tissue treatment aims to regenerate normal tissue and maintain pulp vitality by inducing pulp regeneration using the right material, so that a good percentage and size of material porosity is needed to help cell regeneration by supporting cell proliferation and attachment, stimulating remineralization and differentiation of odontoblast-like cells. Nano-HA has the ability to produce dentine bridges continuously, has porous properties that allow cell growth, improves mechanical properties, but is not anti-inflammatory so that EGCG is added which has the advantage of being an antioxidant, anti-inflammatory which can optimize pulp tissue regeneration and also acts as an antimicrobial by reduce the growth of bacteria in the oral cavity and can trigger the proliferation and differentiation of human dental pulp cells. Purpose: This study aims to prove the difference in surface porosity of nano hydroxyapatite added with EGCG compared to nano hydroxyapatite and aquadest. Methods: This study used a laboratory experimental study with a posttest-only control group design. The research sample consisted of 32 samples which were divided into 2 groups, the treatment group (nano HA - EGCG) and the control group (nano HA - aquadest). Each research group was subjected to freeze drying and SEM tests. Results: There was a significant difference in the percentage of surface porosity between the nano hydroxyapatite added with EGCG compared to nano hydroxyapatite and aquadest.on the results of the Independent T-test (p<0.05). Conclusion: The addition of EGCG to nano hydroxyapatite has a higher porosity percentage compared to nano hydroxyapatite with aquadest.

Abstract

Background: As an effort to treat a deep caries lesion with a diagnosis of reversible pulpitis, one of the treatment options is pulp capping. For decades, calcium hydroxide has been considered the most acceptable pulp capping material and has been routinely used in dental practice, but it also has some weakness. To overcome that, alternative materials are needed that can provide a better effect. Recently, a lot of research has been done using natural ingredients, including Propolis. Propolis has been known to have strong antimicrobial and anti inflammatory properties. Therefore, it is necessary to conduct a deeper study regarding the potency of propolis extract as an anti inflammatory agent for the stimulation of reparative dentin formation so that it can be considered to be used as a pulp capping material. Objective: The aim of this literature review is to highlight the potency of propolis extract as anti inflammatory agent in the natural stimulation of reparative dentin formation. Methods: The search strategy consist of an electronic research using databases such as PubMed, Google Scholar, Science Direct, dan Springer Link for studies published from 2003 to 2021 regarding the potency of propolis extract as anti inflammatory agent for stimulation of reparative dentin formation, including review articles and research articles. Results: Propolis and its constituents have been proven to be used as a potent natural anti inflammatory, it also considered to have the ability to promote reparative dentin formation. However, there are some literatures stated that reparative dentin does not form with the application of propolis, and the causes may vary. Conclusion: Propolis extract has a potency as an anti inflammatory agent in dental pulp inflammation by inhibiting TNFα expression, and increasing TGF-β1 expression, as well as its potency in stimulating the formation of reparative dentin. Based on this review, further studies are needed.
