Abstract

Background: Acrylic prosthesis that are used for a long time are often not sticky anymore and easy off. Treatment that can be done is relining, which is resurfacing with new material addition to prosthesis surface in contact with mucosa. One of materials used is denture reliner made of acrylic material (heat and self cured acrylic). The successful use of this reliner material depends on the retention of acrylic base surface. There is some retentions namely bur strokes, ethyl acetate and Al2O3 sandblast. Purpose: To determine effect of retention in form of bur strokes, Ethyl Acetate and Al2O3 sandblast on acrylic bases surface on adhesive strength of reliner denture material. Method: Research using samples in form of acrylic blocks with a length of 80 mm, a large block width of 10  x10 mm and small block of 10 x 8 mm, reliner material thickness is 3 mm. Total of 64 samples were divided into 2 groups based on reliner materials (heat and self) and each group was divided into 4 groups based on treatment (control, bur stroke, ethyl acetat and Al2O33 sandblast).  All samples were subjected to tensile test using UTM to obtain tensile strength values. Result: Heat CA tensile strength value was greater than self CA and the two groups were significantly different (p<0.05), while lowest tensile strength value in control group followed by  ethyl acetate and  largest value in Al2O3 sandblast  and almost all groups were significantly different (p<0.05). Conclusion: Heat CA is more adhesive than self CA and  retention on acrylic surface is proven to be effective in increasing adhesive strength of acrylic surface against denture reliner.

Abstract

Background: Along with the development of processing goods using machine tools and equipment as well as the use of chemicals, one of the impacts is loud or noisy sound, which can be interpreted as unwanted sound or exceeding threshold and has an opportunity to damage hearing so that can be detrimental. Purpose: To analyze the relationship between the noise intensity and worker's characteristics with hearing disorders at the Dental Engineering Laboratory in the Jakarta area in 2020. Method: This research was an analytical study with a descriptive cross-sectional design with a sample of 30 dental technicians who work in a dental engineering laboratory in the Jakarta area. Each area is taken 6 people. Measurement of noise in the laboratory with a sound level meter and measurement of hearing loss with audiometry. Result: Workers whose noise intensity is >85 dBA have hearing loss, workers whose noise intensity is 85 dBA, 4 people who have hearing loss, workers aged >40 years have hearing loss, while among workers aged ≤40 years, there are 7 people experiencing hearing disorders. workers with >5 years of service experience hearing loss, while among workers 5 years of service, none have hearing loss. Conclusion: There is a significant between noise intensity with hearing loss (p-value = 0.011), it isn't significant between age with hearing loss (p-value = 0.0563), and it isn't significant between tenure with hearing loss (p-value = 0.06).

Abstract

Background: Acrylic denture base material has advantages such as good aesthetics, ease of repair, and affordable price, but this denture has mechanical properties, one of which is low tensile strength so fractures often occur during use. Utilization of natural fibers such as ramie (Boehmeria Nivea) and coconut coir (Coco Nucifera L) can be used as an alternative reinforcement for acrylic denture bases. Purpose: To determine the effect of adding ramie fiber and coconut coir fiber at different concentrations on the tensile strength of the acrylic denture base. Method: This study used a laboratory experimental method with a flat dumbell-shaped specimen with a size of 75 í— 10 í— 3 mm based on ISO 527-1 (2019). The specimens consisted of 42 plates which were divided into 7 groups, namely 6 specimens each group without fiber addition (control), with the addition of ramie fiber 1%, 2%, 3%, and the addition of coconut coir fiber 1%, 2%, 3%. Tensile strength testing using Universal Testing Machine (UTM), data were analyzed by One-way ANOVA test and Post Hoc LSD test. Result: The 3% ramie fiber addition group had the highest tensile strength (76.47 MPa), the 1% coconut coir fiber addition group had the lowest tensile strength (58.91 MPa). There was a significant difference in the results of the control group's tensile strength test and the addition of 3% ramie fiber and 1% coconut coir fiber (p-value < 0.05). Conclusion: The greater the concentration of ramie and coconut fiber additions, the higher the tensile strength value, although the tensile strength value in the coconut fiber addition group was lower than the control group and ramie fiber addition.

Abstract

The use of acrylic denture bases in the oral cavity requires biocompatibility. This study investigated the viability of BHK-21 fibroblast cells after treatment with an acrylic denture base modified using natural fibers. Ramie and banana stem fibers were used as cost-effective alternatives to synthetic fibers. The study involved 42 acrylic resin specimens (10 mm diameter, 2 mm thickness) divided into groups: resin without fibers, 0.5%, 1.5%, and 2.5% ramie fibers, and 0.5%, 1.5%, and 2.5% banana stem fibers. The resin was incubated with cell culture media at 37°C for 7 days. Cytotoxicity testing using the MTT method revealed that all treatment groups had cell viability exceeding 70%, meeting ISO 10993-5 standards. No significant differences in cell viability were observed between the treatment groups and the control (media without specimens). Additionally, adding 0.5%, 1.5%, and 2.5% ramie fibers did not affect BHK-21 cell viability compared to the resin-only control, while adding banana stem fibers increased cell viability compared to the control (P = 0.035; P = 0.021; and P = 0.011). In conclusion, increasing the concentration of natural fibers in acrylic denture bases did not negatively impact fibroblast cell growth.

Abstract

Background of the problem: Adolescents with thalassemia often experience dental health problems due to disease complications and treatment. Prevention can be achieved by improving nutritional status and public education about thalassemia. The program activities that can be a solution to these problems are through education. Objectives: This service aims to improve dental health, understanding of the use of dentures, and nutritional status among adolescents with Beta Thalassemia Major in DKI Jakarta. Methods: The methods used in this activity include socialization and counseling on dental health and thalassemia disease, which were attended by 40 adolescents from the Indonesian Thalassemia Foundation in DKI Jakarta. The stages of the activity include the distribution of activity information, the completion of a pre-test questionnaire, presentation of the material, examination, and evaluation session. Results: The post-test results of the community service activity revealed that 57.5% of participants fell into the high knowledge category, 37.5% into the moderate category, and 5.0% into the low category. Conclusion: This indicates that after this activity, there was an increase in understanding regarding efforts to improve nutritional health, the use of dentures, and the nutritional status of adolescents with beta thalassemia. Recommendations or follow-up: The intervention in the form of socialization and counseling has successfully increased the knowledge of nutritional health, dentures, and the nutritional status of adolescents with beta-thalassemia.
