Abstract

Background: E glass fiber dental is a fiber that is often used in dentistry. The availability of E glass fiber in Indonesia is still very limited. Various types of non-dental glass fiber materials are found in the market as engineering materials with relatively cheap prices so that they are expected to be used as an alternative to E glass fiber dental, which one of is coconut fiber. The composition of non-dental glass fiber is almost the same as that of dental E glass fiber. The composition affects the mechanical properties and chemical properties of the fiber. Glass fiber compositions such as Na2O and K2O will increase water resistance. Method: This study was conducted using a post test only control group design. The material used in this study was a composite of coconut coir fiber. The subjects of the coco fiber composite were divided into 4 groups for solubility test based on ISO 4049. The results obtained were analyzed using one-way ANOVA (p = 0.000). The results showed the lowest mean component solubility (%) was in the coconut fiber composite group A (0.476±0.03) and the highest yield was in the coco coir fiber composite D (0.6±0.01). Results: The results of the one-way ANOVA test showed a significant difference in the coco fiber composite in the solubility of the components (p

Abstract

Background: The prevalence of dental caries in Indonesia reaches 88.8%. Chlorhexidine, although effective, has side effects such as tooth discoloration. Cinnamomum zeylanicum is rich in cinnamaldehyde and eugenol, with antibacterial activity that makes it a natural alternative. Objective: To assess the effectiveness of Cinnamomum zeylanicum essential oil against Streptococcus mutans inoculated in Wistar rats (Rattus norvegicus) in preventing dental caries. Method: This study used 20 male Wistar rats, divided into five groups: negative control, positive control, and three treatment groups with Cinnamomum zeylanicum essential oil concentrations of 6.25%, 10%, and 12.5%. Streptococcus mutans (S. mutans) was inoculated orally in 0.2 ml using a pipette for three consecutive days. During the study, rats were fed a diet mixed with a sucrose solution (600 mg of sucrose dissolved in 1 liter of Aquadest) at a 1:500 ml-to-pellet ratio to induce caries. After 20 days of treatment, data were collected using a bacterial inhibitory zone assay by disk diffusion and salivary pH measurement. Data analysis was performed using one-way analysis of variance (ANOVA), Tamhane’s post-hoc test, and the Wilcoxon signed-rank test. Results: One-way ANOVA test showed no significant differences in the inhibitory zone (p>0.05). Post-hoc tests showed that all groups were not significant (p>0.05). The Wilcoxon signed-rank test showed significant differences in salivary pH before and after treatment (p<0.05). Conclusion: Cinnamomum zeylanicum essential oil has potential as an antibacterial agent and natural alternative in preventing dental caries against S. mutans, and is able to change the salivary pH to alkaline.

Abstract

Dental caries in children remains a significant public health problem in Indonesia, particularly among primary school-aged children. Limited oral health literacy and insufficient involvement of teachers and parents in oral hygiene guidance contribute to the high prevalence of dental caries. This study aimed to enhance children’s oral hygiene knowledge and practices through Training of Trainers (ToT)-based education for teachers and parents within a partnership between the Faculty of Dentistry, Hang Tuah University, and El Rahma Islamic Boarding School, Surabaya. A pretest–posttest design was applied, involving fifth-grade students as research subjects. Teachers and parents received ToT-based training delivered by dental professionals and subsequently provided oral health education to students. Knowledge levels were assessed using questionnaires administered before and after the intervention and analyzed using the Wilcoxon Signed-Rank Test. The results demonstrated a significant increase in students’ mean knowledge scores, from 58.14 ± 21.30 at pretest to 77.21 ± 18.30 at posttest (p < 0.05). In addition, partner satisfaction questionnaires indicated a very high level of satisfaction with the program implementation. In conclusion, ToT-based oral health education involving teachers and parents is effective in improving children’s oral hygiene knowledge and has the potential to promote sustainable oral health behavior changes within the school environment.

Abstract

Dental and oral problems in Indonesian children are caused by low knowledge, comprehension, and behavior that ignores dental and oral health maintenance, resulting in tooth and mouth damage. This activity is in partnership with SD Yapita which is a school supported by the Faculty of Dentistry, Hang Tuah University. The aim is to prepare parents and teachers of Yapita Elementary School students to become ambassadors for oral and dental hygiene so that they can become mentors for their children or students. This method is carried out online and offline from classes 1 to 6 using a simple random sampling technique. The results were statistically analyzed using the Paired T-test. The average pre-test score from the teacher was 60 and the parents were 56, while the post-test result from the teacher was 84 and the parents was 85. The results of the data analysis were normally distributed (p>0.05) followed by the Paired correlation test T-test. The results show a relationship between the pre and post-test of teachers and parents. This shows that this educational activity can increase the knowledge of teachers and parents so that they can become ambassadors of oral and dental hygiene to their children or students.

Abstract

Introduction: Glass ionomer cement (GIC) is widely used because of its chemical adhesion to tooth structure, fluoride release, and biocompatibility. However, its low tensile strength and brittleness limit its application in stress-bearing restorations. Hydroxyapatite (HA) has been investigated as a bioactive filler to improve the mechanical properties of GIC. This study aimed to analyze the differences in the mechanical performance (diametral tensile strength and compressive strength) of Type II GIC modified with hydroxyapatite. Methods: The materials used in this research were Type II GIC (Fuji IX) and pure hydroxyapatite (Sigma Aldrich's). Twenty-eight specimens were allocated into four groups for the diametral tensile strength (DTS) test, and another twenty-eight specimens for the compressive strength (CS) test (n= 7 per group): a control group (K, conventional GIC without modification) and three treatment groups modified with 1% (P1), 3% (P2), and 5% (P3) of hydroxyapatite powder. Mechanical evaluation was performed using a Universal Testing Machine (UTM) at a crosshead speed of 0.5 mm/min. Statistical analysis comprised tests of data normality and variance homogeneity, followed by one-way analysis of variance (ANOVA) and the Least Significant Difference (LSD) post hoc test (p=0.05). Results: The addition of HA altered mechanical performance in a highly concentration-dependent and stress-specific manner. The highest DTS was observed in Group P1, with a value of 9.5300 ± 4.0896 MPa, which was significantly higher than those of the control and all other groups (p<0.05). Conversely, CS was highest in Group P2 (66.7114 ± 11.8779 MPa), which was significantly higher than that of the control group (43.3614 ± 10.6778 MPa, p=0.002). Higher mass loading in Group P3 resulted in a pronounced decline in both tensile and compressive performance. Conclusion: There are differences in the mechanical performance (diametral tensile strength and compressive strength) of Type II glass ionomer cement (GIC) modified with hydroxyapatite. Hydroxyapatite integration enhances the mechanical properties of Type II GIC, with 1% HA improving DTS and 3% HA producing the highest CS.
