Abstract

Background: One of the materials for denture bases is heat-cured acrylic resin (PMMA). This material still lacks impact strength as a mechanical strength property. The addition of reinforcing material is known to increase the mechanical strength of PMMA. One of the reinforcing materials added to PMMA is nano cellulose from rice husks, one of the wastes from agricultural products. Purpose: This study aims to determine rice husk nano cellulose's addition to the PMMA denture base's impact strength. Method:  The research sample consisted of six groups, each group consisting of 8 samples selected by simple random. The PI, P2, P3, P4, P5, and K groups were PMMA with 1%, 2%, 3%, 4%, 5% nano cellulose, and without nano cellulose. Result: Mean impact strength test results were 41.50 x 10-3 ± 3.891 J / mm2 for P1, 44.13 x 10-3 ± 3,980 J / mm2 for P2, 45.63 x 10-3 ± 4,438 J / mm2 for P3, 46.87 x 10-3 ± 4,824 J / mm2 for P4, 49.12 x 10-3 ± 4.016 J / mm2 for P5 and 36.25 x 10-3 ± 1.982 J / mm2 for K. One way Anova test results with p-value of 0.000 indicates differences in the six groups (p<0.05). Conclusion: This study concludes that the impact strength value of PMMA with the addition of rice husk nano cellulose has increased compared to the control group without the addition of rice husk nano cellulose.

Abstract

Background: Salivary pH can rise or fall influenced by intrinsic and extrinsic factors. Sleep deprivation is one example of intrinsic factors. Sleep deprivation causes a reduction in sleep time at a certain time. Purpose: Analyze the effect of different types of sleep deprivations and sleep recovery on salivary pH. Method: This study was experimental research with a post-test only with a control group design. Thirty white Wistar strain rats were randomly divided into 5 groups: healthy control group (KI), partial sleep deprivation (PSD/KII), total sleep deprivation (TSD/KIII), partial sleep deprivation, and continued sleep recovery (PSD+SR/KIV) and total sleep deprivation and continued sleep recovery (TSD+SR/KV). The treatment is carried out on a single platform method. Salivary pH was measured with the help of color-coded pH strips that were given grading after the completion of sleep deprivation induction. Result: The mean decrease in salivary pH was highest in the TSD group. One Way ANOVA test showed significant differences (p <0.05) in the control group with PSD and TSD, the PSD group with PSD+SR, TSD group with PSD+SR and TSD+SR. Conclusion: Sleep deprivation is proven to reduce the pH of Saliva. Total sleep deprivation is a chronic condition that has the most influence on decreasing salivary pH. The effect of decreasing salivary pH due to sleep deprivation is proven to be overcome by sleep recovery.

Abstract

Background: infectious disease is one major important health issue. Dental technician is an occupation which has a risk to get infectious disease transmitted from saliva, blood or contaminated tools if universal precaution utensils did not use properly. Infection can be transferred through dental impression from surface contact, handpiece, burs, pumice, aerosol etc. Purpose: This study aim to find out desinfection implementation in dental laboratories located in East Java as a preventive and controlling action towards cross infection. Method: Data were obtained through questionnaire, the questionnaires were designed to get the information related to infection control from dental laboratories in East Java. The survey was conducted in 36 dental laboratories listed by Association of Dental Technician in East Java. Result: As much as 90% dental laboratories did not performed desinfection procedure to the dental impression received from dentist and never follow any desinfection training. AS much as 95% Dental laboratories believe universal precaution utensils can be infected but only 50% utilize universal precaution utensils. Eventhough if such infection occurs, the owner will be fully responsible. Conclusion: Prevention and management towards cross infection control in dental laboratories located in East Java still very low. Development and supervision towards dental laboratories operational by Indonesian government  and professional association need to be improved. Education regarding infection control need to be performed through trainings and inserted infection control matters in dental technician study programme curriculum in Indonesia.

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: In acrylic removable dentures, brokenness often occurs in the midline region of the maxilla. Resistance to fracture depends on the physical properties of the material namely the transverse strength. This can be prevented by the addition of glass fibers. Tea is consumed by many people, acrylic resin dipped in steeping tea will reduce the strength of acrylic resin. How the physical properties of acrylic resin are modified by the addition of glass fiber effect when immersed in a tea solution. Purpose: This study was to determine the strength of transverse acrylic resin with the addition of glass fibers soaked in tea. Method: Rectangular acrylic resin with a size of 10 x 65 x 2.5 mm. The number of samples is 24. divided into 4 groups. namely 2 groups without glass fiber and 2 groups with glass fiber. The sample is measured by transverse strength using an autograph (Shimadzu) tool, then data is analyzed using ANOVA. Result: Acrylic resin without glass fiber immersed in tea solution decreases its transverse strength. while the acrylic resin was given glass fiber the strength value of the transversion does not differ significantly either soaked or not. Conclusion: Acrylic resin which is given glass fiber and soaked in tea does not reduce the strength of the transversion. This is due to the glass fiber filling the cavity in the acrylic resin.

Abstract

Background: Periodontal disease are common dental and oral health problems in the community. Porphyromonas gingivalis (Pg) is one of the main causes of the periodontal disease. The alveolar bone resorption could be as severity indicator of the disease, so that need a material that can help a process of bone remineralization. Osteoblasts are bone-forming cells that are responsible for the mineralization of the bone matrix. Purple leaf is one of the thirteen commodities developed by DitjenPOM as a superior medicinal plant. Purpose: To determine the effect of 2,5%, 5% and 10% purple leaf extract (EDU) of osteoblasts cells in wistar rats induced by Pg. Method: Thirty male wistar rats divided into 5 groups, namely N (without treatment), K (Pg), P (Pg+EDU 2,5%), P2 (Pg+ EDU 5%), P3 (Pg+EDU 10%). EDU administration once a day for 7 days. The mice were decaputated on the 7 th day and the left mandible was taken to make preparations followed by HE staining, observation and calculation of the number of osteoblast cells in 3 different fields. The results of the observations (data) were added up, averaged and analyzed by One Way ANOVA. Result: The group induced by Pg and EDU had a higher average number of osteoblasts than the K and N group. Conclusion: Purple leaf extract (EDU) can increase osteoblasts cells in the alveolar bone of male wistar rats induced by Pg with the highest number of osteoblasts in the 10% concentration.
