Abstract

Background: Nanohybrid composite resins have many advantages, but one disadvantage is their absorbent nature which can lead to discoloration. Phenols and flavonoids in nano propolis cause diffusion and affect the matrix and pigments of nanohybrid composite resins. The accumulation of reduction-oxidation reactions causes new compounds of nanohybrid composite resins to occur so that they have different colors. Objective: The study was conducted to determine the changes in surface color of nanohybrid composite resin after immersion in nano propolis at 5% concentration. Methods: Research experimental laboratory method with pre and post test design was applied to 25 nanohybrid composite resin fruit samples of size (5x5x1.5) mm embedded in bovine incisive, then immersed in 5% nano propolis and 25 ml of distilled water at 37oC for five days. The color change (ΔE) was measured with a DSLR camera and processed with Adobe Lightroom Classic software in CIE L*a*b* format. Results: The anova test on ΔE in the data showed the p-value of sphericity assumed was smaller than 0.05. There is a difference in the average measurement results on the first day to the fifth day in the treatment group. Independent t-test of control and treatment data showed a significant difference in measurement results. The results of the post hoc test with the Tukey method showed that the treatment groups at 4x24 hours and 5x24 hours did not have significant differences. P-value at 4x24 hours and 5x24 hours was 0.957. Conclusion: There was a change in the surface color of the nanohybrid composite resin after being immersed in a nano-solution of propolis with a concentration of 5%.

Abstract

Background: Dental caries is a common disease among the Indonesian population, with a prevalence of dental caries in Indonesia reaching 88.8%. Streptococcus mutans is one of the types of bacteria found in caries lesions. Nano propolis has antibacterial properties that can help inhibit the growth of Streptococcus mutans bacteria, reducing the risk of dental caries. Objective: This study aims to determine the effective concentration of nano propolis ranging from 2.5% to 0.625%. Methods: The research evaluates various concentrations of nano propolis, and the minimum concentration that inhibits the growth of Streptococcus mutans is observed using the colony count method. Results: The growth of Streptococcus mutans at a concentration of 2.5% nano propolis was 0, at 1.8% it was 6, at 1.25% it was 11.4, and at 0.625% it was 42. The positive control group containing BHIB media and Streptococcus mutans bacteria showed an average colony growth of 161. Conclusion: Nano propolis at a concentration of 1.25% is effective in inhibiting the growth of Streptococcus mutans.

Abstract

Introduction: Diabetes mellitus is a chronic metabolic disorder characterized by high blood sugar levels. It is a global health problem that can increase the risk of tooth decay and requires conservative dental treatment. Several factors impact the severity of tooth decay, sugary drink consumption is one of them. This study aimed to investigate the association between tooth decay in patients with diabetes mellitus who regularly consume sugary drink versus those who do not. These patients visited Conservative Dentistry Section, Universitas Airlangga Dental Hospital Surabaya, Indonesia, during Jan-Mar 2023. Methods: This study involved 37 patients with diabetes mellitus and posterior tooth decay. Demographic data were gathered from personal interview and dental records. Statistical analysis was done using chi-square analysis. Results: sugary drink consumption has a significant difference (p<0.05) among the patients with posterior tooth decay and diabetes mellitus. Conclusion: sugary drink consumption influences the severity of tooth decay in diabetes mellitus patients.

Abstract

Background: Radiography is essential in dentistry for diagnosis and treatment planning, with two-dimensional imaging such as panoramic and periapical radiographs being commonly used. The advancement to three-dimensional imaging, specifically Cone Beam Computed Tomography (CBCT), provides more detailed visualization but remains underutilized due to limited availability and knowledge among dentists in Indonesia. Purpose: This research is aimed to determine the knowledge and experience of using 2D and 3D diagnostic imaging among dentists in Surabaya. Methods: This research is using an observational descriptive study with a cross-sectional design consisting of 100 dentists who are domiciled in Surabaya and registered with PDGI in Surabaya. Results: The result showed that dentists’ knowledge of 2D diagnostic imaging with a good category has a percentage of 18%, quite good category with 49% and poor category with 33%. Meanwhile, the dentists’ knowledge of 3D diagnostic imaging with a good category has a percentage of 9%, quite good category with 36% and poor category with 55%. Around 88% of respondents have referred their patients for panoramic and periapical radiographs, while only about 22% of dentists have referred their patients for CBCT examinations. Conclusion: The knowledge of dentists regarding 2D diagnostic imaging is quite good, while the knowledge of dentists regarding 3D diagnostic imaging is low. The majority of dentists in Surabaya often refer their patients for panoramic and periapical radiographic examinations compared to referring them for CBCT examinations.

Abstract

Background: Dental caries affects 57.6% of the Indonesian population, with Enterococcus faecalis found in 80% of deep caries cases. Conventional materials used in vital pulp therapy (VPT), such as calcium hydroxide, have limitations including transient antibacterial action and poor sealing capacity. This prompts the exploration of alternative materials like epigallocatechin-3-gallate (EGCG), a polyphenol from green tea with antimicrobial activity, and tricalcium silicate (C₃S), a bioactive cement known for dentin regeneration potential. Purpose: This review evaluates the synergistic antibacterial potential of EGCG and C₃S combinations against E. faecalis, and assesses their feasibility as an alternative in VPT. Review: EGCG disrupts bacterial membranes, inhibits biofilm formation, and suppresses virulence factors, but lacks remineralization capability. Conversely, C₃S promotes dentin repair and creates an alkaline antibacterial environment, though its efficacy diminishes over time. Their combination compensates for each other’s limitations: EGCG enhances antimicrobial potency while C₃S provides long-term alkalinity and regenerative support. Conclusion: The EGCG–C₃S combination exhibits synergistic antibacterial and regenerative effects, offering a promising alternative to current VPT materials.

Abstract

Background: Lactobacillus acidophilus is involved in secondary caries that can accelerate demineralization of the tooth surface. Bacteria forms biofilm as part of a defense mechanism. One of the caries treatments is direct pulp capping with calcium hydroxide (Ca(OH)2) as the gold standard. Due to its high pH, calcium hydroxide can induce necrosis of pulp tissue when it comes into direct contact. Propolis is a natural material produced by honey bees. Propolis has many benefits including antibacterial effects. Nanoparticles are microscopic particles measuring 1-100 nm, reducing particle size can increase the rate of dissolution and absorption. Purpose: This study aims to prove the difference in the biofilm inhibitory ability of a micro and nano-sized combination of propolis and Ca(OH)2 against L. acidophilus biofilms. Methods: This study used true experimental laboratories research with treatment groups that included a control, combination of micro-sized propolis and Ca(OH)2 and combination of nano-sized propolis and Ca(OH)2. Results: The results showed that there was a significant difference between the micro and nano-sized combination of propolis and Ca(OH)2 in inhibiting biofilm growth, with the combination of nano-sized propolis and Ca(OH)2 showing higher effectiveness compared to the micro-sized one. The combination of nano-sized propolis and Ca(OH)2 produced an inhibition value of 84.35%, while the micro-sized one produced an inhibition value of 77.18%. Conclusion: The combination of nano-sized propolis and Ca(OH)2 had a greater biofilm inhibition compared to the combination of micro-sized propolis and Ca(OH)2.
