Abstract

Immediate Dentin Sealing (IDS) is a conservative procedure performed to protect the exposed dentin surface after tooth preparation, especially for indirect restorations. Indirect restorations are a common procedure in dentistry for replacing the crown structure of teeth, including various types such as jacket crowns, bridge prostheses, endo crowns, inlays, and veneers. The tooth preparation process can expose dentin tubules, which can trigger pulp tissue irritation and the risk of infection, as well as interfere with the adhesion of the final restoration. Post-IDS surface treatment methods can help enhance the bonding strength. The research aims to investigate the influence of different post-IDS surface treatment on the shear bond strength of lithium disilicate.The study involved 30 upper premolar teeth, divided into three groups. After crown portion buccal surface preparation, all samples underwent IDS, followed by immersion in water and 24-hour incubation. Subsequently, each group received a specific surface treatment: Group I with nylon brush, Group II with nylon brush + pumice, and Group III with sandblasting using aluminum oxide. Lithium disilicate was then cemented on all samples, followed by another 24-hour incubation before shear bond strength testing. Shear bond strength values in MegaPascals (MPa) were analyzed using one-way ANOVA and post hoc Games-Howell tests with a 95% confidence level.The statistical analysis revealed a significant influence of the different treatment groups on shear bond strength (p < 0.05). In conclusion, this study demonstrates a significant impact of varying post-IDS surface treatments on the shear bond strength of lithium disilicate.

Abstract

17% EDTA is a chelating agent used to clean the smear layer. Novel silver citrate (NSC) is a new material with the same use, while 0.2% chitosan nanoparticles are a material that has been widely studied. The agitation technique influences smear layer cleanliness by optimizing the penetration of irrigation material. Agitation techniques are sonic and ultrasonic agitation techniques; each has its advantages and disadvantages. The research objective is to evaluate the effect of final irrigation materials, agitation techniques, and a combination of both on the cleanliness of the smear layer in the apical third of the root canal.Forty-five premolars were prepared with a rotary instrument. Samples then randomly divided into 3 experimental groups (n=15). Group 1 used 17% EDTA, group 2 used NSC, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5) with subgroup A using manual agitation technique, subgroup B sonic agitation, and subgroup C ultrasonic agitation. The samples were sectioned and then examined under SEM with 5000x magnification to evaluate the cleanliness of the smear layer. The results from SEM were scored and then analyzed using Chi-Square test (IBM SPSS Statistics 29.0.1.0).Final irrigation agents of 17% EDTA, NSC, and 0.2% chitosan nanoparticles resulted in the same cleanliness of the smear layer (p˃0.05). The ultrasonic agitation technique showed better cleanliness of the smear layer than the sonic agitation and manual agitation techniques (p˂0.05). The final irrigation material combined with agitation techniques resulted in the same cleanliness of the smear layer (p˃0.05).

Abstract

Background: Free radicals produced by hydrogen peroxide after teeth bleaching which diffuse through the enamel and dentinal tubules can trigger inflammation of the pulp.  To overcome this negative side effect, exogenous antioxidants have been proposed.  This research was conducted to determine the effect of natural antioxidants, namely 5% and 10% green tea, which was applied on rat molars teeth that were bleached using 40% hydrogen peroxide. Methods: Fifteen molar teeth of male Wistar rats were bleached using 40% hydrogen peroxide on their occlusal surface. Furthermore, the control group (Group I) rinsed using warm distilled water, while in Group II and Group III, the teeth were rinsed using 5% and 10% green tea extract gel. Wistar rats were sacrificed on the fifth day after treatment, followed by hematoxylin-eosin staining. Histological examinations were observed under a light microscope using 400x magnification and the number of the neutrophil were counted. Result: One-way ANOVA test showed that there was a significant effect of green tea extract gel concentration on the number of neutrophils (p 0.05).  Post hoc test results showed that there were significant differences in all pairs of groups compared (p 0.05). Conclusion:  Group III which was treated using10% green tea extract gel has the lowest number of neutrophil compared to Group II which was treated using 5%  green tea extract hel and the control group.

Abstract

Background: According to a previous study, hydroxyapatite (HA) has the potential to be used in dentistry, but it still needs further research, especially as a biomaterial for pulp capping. The pulp capping treatment can maintain pulp vitality and induce dentin reparative formation. Calcium hydroxide is the gold standard of pulp capping material, but it can cause tunnel defects. Several studies made a crosslink with epigallocatechin-3-gallate (EGCG) and hydroxypropyl methylcellulose (HPMC) to improve the effect of hydroxyapatite as a biomaterial. The HA-EGCG-HPMC combination is expected to have the potential as a bioactive material. In this study, HA-EGCG-HPMC was characterized physicochemically by several criteria, such as the gelation time, pH, and antibacterial effect against Aggregatibacter actinomycetemcomitans. This study aims to determine the physicochemical characteristics of the HA-EGCG-HPMC material as a pulp capping materialMethod: This research is an in vitro laboratory experimental study design. Hydroxyapatite powder was dissolved with distilled water at concentrations of 4%, 2%, and 1%, with 10µmol/mL EGCG and hydroxypropyl methylcellulose as the carrier agent. Characterization of the samples measured are gelation time, pH, and antibacterial effect by microdilution method. Result: The HA-EGCG-HPMC combination has an ideal gelation time of about 23-31 minutes, and its pH is within the range of 7.28 - 7.33. However, the HA-EGCG-HPMC does not yet have an antibacterial effect against Aggregatibacter actinomycetemcomitans.Conclusion: The hydroxyapatite, EGCG, and hydroxypropyl methylcellulose can be used as a bioactive material, such as pulp capping material seen from physicochemical characterization that can be developed further.

Abstract

Background: Intracanal medicaments Ca(OH)₂ must have the ability to contact directly with bacteria adhering to the dentinal tubules. However, the narrow and complex shape of the root canal makes it difficult for Ca(OH)2 to penetrate the root canal apically. This research aimed to assess the flowability of nanoparticle Ca(OH)₂ Palimanan by quantifying the penetration of the coronal, middle, and apical thirds of the root canal.Methods: This research comprised two distinct groups: one group included nanoparticles of Ca(OH)₂ Palimanan, while the other consisted of conventional Ca(OH)₂. The paste was then applied to standardized root canals (n=3 per group) with 5 times measurements for each sample. All samples were then incubated at 37oC, 100% humidity. The flowability of the root canals was measured using scanning electron microscopy (SEM) on day 14. The data was analyzed using ANOVA and a post-hoc t-test, with a significance level of p<0.05.Results: The use of Ca(OH)₂ Palimanan has been found to be more effective in reaching deeper into the dentinal tubules of the root canal, particularly in the coronal, middle, and apical areas, compared to traditional Ca(OH)₂. This occurs because the particle size of Ca(OH)₂ Palimanan is smaller with a more rounded shape than conventional Ca(OH)₂ so that it to flow into narrow and complex areas, especially in the apical root canals.Conclusion: Nanoparticle Ca(OH)₂ Palimanan flow deeper than conventional Ca(OH)₂

Abstract

Background: One type of restorative substance is composite resin, which also comes in microhybrid form. Surface roughness is one of the clinical characteristics that may serve as a predictor of the longevity of restorative materials. The habit of drinking low-pH beverages is one of the things that influences surface roughness. One of the most consumed beverages in society is a fermented milk beverage. Fermented milk is usually safe for consumption by those with sensitivity to dairy products since the bacteria in it can break down lactose into lactic acid. Lactic acid, which has a pH of 4.2–4.8, is found in fermented milk. The purpose of this research is to ascertain how soaking fermented milk affects the microhybrid composite resin's roughness. Methods: This study uses a pre-test post-test design methodology and is conducted in a laboratory setting. There are 27 samples of microhybrid composite resins that are conducted with fermented milk. Prior to and following immersion, the surface roughness of the microhybrid composite resin was measured using a surface roughness tester as part of this study. Results: On the first through the seventh day of immersion, there was a noticeable rise in the surface roughness of the Microhybrid composite resin submerged in fermented milk. Conclusion: After being immersed in a solution of fermented milk for one, four, and seven days, the nanohybrid composite resin is affected by its roughness.

Abstract

Background: Fatigue stress carried on by repetitive occlusal loads that fail to recover teeth, as in bruxism cases, can weaken and lower the material's strength. Patients with bruxism receive dental care to minimize biological costs while halting further tooth loss and restoring function and attractiveness. It has been difficult to combine the aesthetic appeal and strength of the restorative materials up to this point. The purpose of the review article is to determine how durable dental crown materials are in patients with bruxism so that this can be considered when selecting crown materials.Method: This literature review follows the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). During the search and selection process, studies were selected using the framework (P), Intervention (I), Comparison (C), Outcomes (O), and Study design (S; PICOS): (P): Patients treated with crowns; (I): crown in bruxism patient; (C): type of crown material (O): Main results are: outcome of crown use in bruxism patients (S): Randomized controlled trial (RCT), cohort studies, prospective studies, and case series were included.The data search process via: (PubMed), Google Scholar, Scopus, and Science Direct, is limited to 2018-2024. The keywords used are (bruxism OR "sleep bruxism") AND ("dental crown" OR "ceramic crown") AND (zirconia OR "lithium disilicate")). Of the 1416 articles screened, three articles were included in this review.Result: A total of three studies met the inclusion criteria, consisting of one randomized clinical trial, one prospective clinical study, and one observational case series. The findings demonstrated high survival rates and low complication rates for zirconia and lithium disilicate crowns in bruxism patients. The only randomized clinical trial reported no significant difference between the two materials in terms of survival and complications. Observational studies supported favorable clinical performance of zirconia crowns, although complications were more frequently observed in patients with bruxism.Conclusion: Within the limitations of this review, zirconia and lithium disilicate crowns demonstrate favorable short-term clinical performance in patients with bruxism. However, the limited number of high-quality studies highlights the need for further well-designed clinical research.

Abstract

In this study, an adult rat's calvaria was used to examine craniofacial anatomical landmarks of maxilla and mandible using Micro-Computed Tomography (micro-CT) as the marker of craniofacial growth and development in rat. It is used to assist research, translating landmark points for diagnosis. Landmarks on the rat’s calvaria were determined to set the measurements of two specified points. One of the ways to validate craniofacial growth and development is to look at the differences between craniofacial before and after a specified period or treatment. With micro-CT analysis, the researchers are more precise in determining the difficult points in the cranium.The sample analysis was carried out and measured by DataViewer version 1.6.0.0 64-bit Application. CTVox version-3.3.1 64-bit is used to display 3D visuals. Reconstruction results after adjusting the data range were 30-255 (the color range 0-255). The machine used was Bruker SkyScan-1173 High Energy Micro-CT. Findings anatomical landmarks for the examples, the maxilla determined I for the point on premaxilla between jawbone and lingual surface of upper incisors. In the mandible, I’ for the most anterior edge of the alveolar bone on the convexity of the lower incisor. The unevenness of the cranium made manual measurements difficult and not possible. However, this micro-CT method makes the landmark point determination more detailed and dependable. This makes geometric measurements of craniofacial more reliable. Micro-CT analysis is a more dependable method to determine anatomical landmarks and measure craniofacial structures as the marker of craniofacial growth and development in rat.
