The thermoplastic nylon denture base material is prone to discoloration because its amide bonds absorb water easily. Titanium dioxide (TiO2) nanoparticle have long been used as a denture base coating. Meanwhile, coffee contains chlorogenic and tanic acid, which can change the color of denture bases. The purpose of this study was to examine the effect TiO2 coating and duration of coffee immersion on discoloration of thermoplastic nylon denture base. Samples consisted of 24 thermoplastic nylon in square-shaped (30 x 30 x 2 mm), divided into 4 groups (n = 6). They were control (without TiO2 coating) and treatment (with TiO2 coating) groups, which then were immersed in coffee solution for 15 and 30 days. Discoloration test was conducted using spectrophotometer by measuring the delta absorbance of light before and after coffee immersion. The result showed that the lowest delta absorbance was in the 15-day treatment group (0.011 ± 0.005) and the highest was in the 30-day control group (0.077 ± 0.027). Two-way ANOVA test showed that TiO2 coating and coffee immersion had an effect on discoloration of thermoplastic nylon (p <0.05). Post hoc LSD test showed that there were significant differences between the control and treatment group at 15 and 30 days of coffee immersion (p <0.05). In conclusion, TiO2 as a thermoplastic nylon denture base coating can reduce discoloration by coffee immersion for 15 and 30 days. There were no differences between 15 and 30 days of coffee immersion on thermoplastic nylon’s discoloration in the control and treatment groups.

The osseointegration process of dental implants begins with osteoblast differentiation and proliferation, which is an important aspect of the bone regeneration process. Platelet-rich fibrin (PRF) is a platelet that contains a large amount of fibrin and growth factor, which is widely used to accelerate bone regeneration. This study aims to determine the effect of PRF on the acceleration of osteoblast proliferation after endosseous dental implant insertion. Twelve male Wistar rats weighing 250 to 300 gr of 8 to 15 weeks as an animal model were divided into two groups, the control group and treatment group, based on days and PRF treatment. Three ml of Wistar rat blood was obtained and centrifuged for 12 minutes at a speed of 2700 rpm to make PRF. Afterward, platelet-rich fibrin was applied to implant bed, and the dental implant was inserted at the lateral epicondyle of the right femur in 3 mm depth and 1.8 mm diameter dimension. Incontrol groups, dental implants were immediately inserted after implant bed preparation without PRF administration. Observation of the Wistar rats was carried out on days 14 and 28 for each group. The rats were terminated accordingto the timeline of group design. The epicondylus lateralis femoris dextra bone of the rats was taken and fixed with 10% buffered formalin solution. Then, histological samples were made with hematoxylin-eosin staining. Sample observation was done under a light microscope to calculate the number of osteoblasts. The data were analyzed using the two-way ANOVA test, followed by LSD post hoc test. Based on the two-way ANOVA test, there was a significant difference between control groups and treatment groups (p<0.05), and there were significant differences between the observation result of days 14 and 28 (p<0.05). The application of PRF increased osteoblast proliferation for the first 14 days, but the rate decreased after that. Based on the LSD post hoc test, there were differences in osteoblast proliferation between the treatment and control group (p<0.05). Thus, it is concluded that platelet-rich fibrin increased the acceleration ofosteoblast proliferation after endosseous dental implant insertion.

Background: Abalone (Haliotis varia Linnaeus) shells possess a high arginine content and are expected to be an alternative desensitisation material that is both insoluble and able to properly close dentinal tubules. Different methods of manufacturing abalone gel affect the molecular weight, hydrophilic or hydrophobic properties and protein content of the lysis. Purpose: This study aimed to determine the effects of different manufacturing methods on the dentinal tubule closure of abalone desensitisation gel. Methods: This study involved the extraction of abalone shells followed by preparative and thin-layer chromatography. The drying of the samples was carried out by the precipitation, drying, and addition methods. The research was divided into eight treatment groups, each consisting of three samples (F1, F2, F3). Each sample was applied to two study subjects’ post-extracted third molars, which were cut into disc shapes and subsequently etched with 6% citric acid. The percentage of dentinal tubule occlusion was calculated by Image J (NIH, USA) software. Data were analysed using three-way ANOVA. Results: The results showed that there were significant differences (p < 0.05) both in terms of the effects of the samples with deposition and addition on the occlusion of the dentinal tubules and in terms of the interactions between the samples with drying and addition. There was no significant difference (p > 0.05) in terms of the interactions of the samples’ three manufacturing methods. Conclusion: The manufacture of abalone gel as a desensitisation material requires a minimum of two interactions between the sample-making method and the addition, deposition, and drying methods. The best method was deposition.

Tindakan operasi pada daerah maksilofasial dapat mengakibatkan cacat wajah, gangguan fungsi bicara, penelanan, pengunyahan, estetik serta gangguan kejiwaan. Hilangnya kontinuitas mandibula dapat mengganggu keseimbangan fungsi mandibula, menyebabkan gerakan mandibula yang berubah-ubah, sehingga terjadi kecacatan, sulit menelan, gangguan bicara dan artikulasi, serta deviasi dari sisa fragmen menuju sisi yang dioperasi. Saat membuka mulut, deviasi ini meningkat dan mengarah ke pembukaan dan penutupan secara angular. Perangkat korektif bernama guide flange prosthesis ditunjukkan untuk mengatasi manifestasi klinis tersebut. Tujuan laporan kasus ini adalah untuk mengkaji penggunaan mandibular guide flange prosthesis pada pasien pasca hemimandibulektomi dekstra, sebagai rehabilitasi fungsi pengunyahan, penelanan, fonetik dan estetika. Kesimpulan dari laporan kasus ini adalah protesa mandibula dengan guide flange dari bahan resin akrilik dapat merehabilitasi defek pada mandibula pasca hemimandibulektomi sehingga mengembalikan fungsi pengunyahan, fonetik, proses penelanan dan estetika.
