Sugarcane bagasse (Saccharum officinarum L.) is a CNCs source with a high CNC content (72.5%). Objective: This study aimed to determine the effect of the addition of sugarcane bagasse CNCs on the mechanical properties of GIC. Methods: In total, 42 GIC (Fuji IX, GC, Japan) samples were divided into six groups, with various concentrations of CNCs, added to the samples. After 24 h immersion in distilled water at 37°C, the samples were analyzed using the Vickers hardness test. The samples were also characterized by transmission electron microscopy (TEM). For statistical analysis, a one-way analysis of variance, followed by Tukey's post hoc test, was applied. A value of P < 0.05 denoted statistical significance. Results: The TEM revealed crystalline particles in the form of nanocrystals, with varying particle sizes (lengths of 100–200 nm and diameters of 4–19 nm). The addition of 0.4% of CNCS from bagasse fiber to GIC increased the Vickers hardness of the material by 38.89% (P < 0.05).

Objective: The aim is to examine the differences in efficacy between eucalyptus oil (Eucalyptus globulus), sweet orange oil (Citrus sinensis), and grapefruit oil (Citrus paradisi) as bioceramic sealer solvents.

After 72 h, the sealer samples were weighed to obtain their initial weights. Then, they were divided into three groups of ten, which were immersed in 1 ml of eucalyptus, sweet orange, or grapefruit oil for 1 min, and one group of two, used as negative controls. The sealer samples were placed in an incubator for 24 h to dry and weighed once more to obtain their final weights. The differences in weight were calculated and analyzed using one-way analysis of variance.

Therefore, many new irrigation solutions, such as mixtures of tetracycline, citric acid, and detergent (MTAD) and a mixture of chlorhexidine (CHX) and ethylenediaminetetraacetic acid (EDTA) have been introduced as the alternatives to NaOCl. Objectives: The objectives of this study are to analyze the differences in the effects of MTAD and mixtures of CHX and EDTA on the growth of Enterococcus faecalis ex vivo.Methods: This study used 28 lower premolars, divided into seven groups. Group I received MTAD. Group II received MTAD with CHX. Group III received a mixture of CHX and EDTA. Group IV received a 2% CHX solution. Group V received 17% EDTA. Group VI received a 5.25% NaOCl solution, which served as the positive control, and Group VII received sterile distilled water, which was the negative control. The effectiveness of various irrigation solutions in preventing the growth of E. faecalis was measured by the zone of growth inhibition and colony counts. Results: A one-way analysis of variance revealed a significant difference among the tested irrigation solutions, both in terms of zone inhibition of E. faecalis and E. faecalis colonies counting (P < 0.05).

Composite resin is the material of choice today, but the filler composition of the resin varies. Packable composite resin has good mechanical properties, but its high viscosity makes it hard to manipulate. Several methods, such as preheating, are used to decrease this viscosity. A syringe of composite resin might be preheated several times, but the effect of repeated preheating is unknown. Objectives: The purpose of this research was to analyze the effect of repeated preheating on the mechanical properties of a composite resin with different fillers. Method: Microhybrid, nanohybrid, and nanofill composite resins were preheated (ten times, twenty times, and control), molded into cylinder molds 6 mm in diameter and 3 mm in height, flattened with a celluloid strip, and polymerized with an light-emitting diode light-curing unit for 40 s. A total of 180 specimens were tested. The specimens were divided into two groups: Group 1 was immediately tested using a universal testing machine. Group 2 was soaked in 37°C artificial saliva for 24 h before testing. Each specimen was tested using the universal testing machine with the pressure side with a 1 mm/s crosshead speed. Result: Nanohybrid composite resin had the most stable diametral tensile strength after repeated preheating, whereas nanofill composite had the weakest strength. The increase and decrease in the diametral tensile strength in each group were not statistically significant. Conclusion: Repeated preheating does not significantly affect the diametral tensile strength of composite resin.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"4 1","pages":"44 - 48"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43776494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The aim of this study is to analyze the differences in knowledge and attitude between students from DEIs that have implemented IPE and those who have not. Method: Descriptive analytic observational research with cross-sectional design. Knowledge is measured via a questionnaire designed by the authors, and attitude is measured using the interprofessional-attitude-scale questionnaire.

Result: Statistical testing shows that students from DEIs that have implemented IPE better understand the benefits, competencies, and approach of IPE with a P < 0.05. The Kruskal–Wallis test for attitude also found better results for students from DEIs that had implemented IPE in terms of teamwork, role and responsibility, interprofessional bias, and diversity and ethics with a P < 0.05.

Bacterial removal from the root canal can be achieved with a mechanical approach using an instrument and a disinfecting irrigation agent. Enterococcus faecalis is the most prevalent bacteria found in root canals. Research studies have also been conducted to examine irrigation systems using herbal products such as drumstick tree leaf (Moringa oleifera) instead of NaOCl. Active compounds in M. oleifera, such as flavonoids, tannins, saponins, alkaloids, phenolics, and triterpenoids, possess antibacterial effects. Objectives: The aim of this study is to assess the antibacterial effect of drumstick tree extract (M. oleifera) in several concentrations (25%, 50%, 75%, and 100%) as an irrigation solution against E. faecalis through in the root canal ex vivo. Methods: This study used 24 mandibular premolars, divided into six category groups. Group 1 received 5.25% NaOCl as a positive control, Group 2 received 25% M. oleifera extract, Group 3 received 50% M. oleifera extract, Group 4 received 75% M. oleifera extract, Group 5 received 100% M. oleifera extract, and Group 6 received irrigation using phosphate-buffered saline as a negative control. Quantitative polymerase chain reaction methods used to analyze the E. faecalis number in the root canal after treatment with M. oleifera extract. Results: A one-way ANOVA showed significant differences (P = 0.05) between the three types of irrigation solutions against E. faecalis. Among the six study groups, the most prominent efficacy was found in Groups 1, 4, and 5. Conclusion: M. oleifera extract solution at concentrations of 75% and 100% is as effective as 5.25% NaOCl.

The World Health Organization (2012) released global policy recommendations that cover education, regulation, incentives, and personal and professional support to overcome this issue. However, they have not been able to completely solve the issue, as is shown by a description of Indonesia's Health Profile (2018), which highlights that 43.53% of public health center lack of dentists. The number of studies concerning the real condition experienced by dentists working in rural and remote areas of Indonesia is still limited.

Methods: This study used questionnaire to collect data which was designed based on seven major themes and inserted in Google Form. The link was distributed to dentists who work in rural and remote areas of Indonesia. The sample was selected based on random sampling techniques. Result: The study showed that 45.90% of respondents were not satisfied working in rural and remote areas.
