Introduction: Acrylic resin is still the most commonly used denture base material due to its ideal properties. However, acrylic resin denture fractures are still considered a major unsolved problem thus the addition of nanoparticles as filler was performed to increase its mechanical properties. The purpose of this study was to discovered the effect of nanoparticles TiO2 on the flexural strength of acrylic resin denture plate. Method: This study used 27 heat-cured acrylic resin specimens sized 65 x 10 x 2.5 mm. The samples were divided into three concentration groups (n = 9), the control group; 1% of nanoparticles TiO2; and 3% of nanoparticles TiO2. The flexural strength was tested using the Universal Testing Machine. All data were analysed using the one-way ANOVA test with 95% confidence level then continued with the Least Significant Difference (LSD) test. Results: There were significant flexural strength differences in different concentration of nanoparticles TiO2. The highest flexural strength value was found in the 1% of nanoparticles TiO2 group (106.99 ± 6.09 MPa), whilst the lowest flexural strength value was found in the 3% of nanoparticles TiO2 group (91.64 ± 5.38 MPa). Significant flexural strength difference was found between the control group and the 1% of nanoparticles TiO2 group, and also between the 1% of nanoparticles TiO2 group with the 3% of nanoparticles TiO2 group (p < 0.05). Conclusion: From this study can be concluded that concentration of 1% of nanoparticles TiO2 was able to increase the flexural strength of acrylic resin denture plate.

Introduction: Ethylene Diamine Tetra Acetic Acid (EDTA) 18% irrigation solution is one of the chelating agents that able to remove calcium hydroxide (Ca(OH)2) from the root canal wall. Failure of root canal treatment can be caused by the presence of residual calcium hydroxide in the root canal wall, thus blocking the bond between the medication and root canal filling material with the root canal wall. This study was aimed to observe the EDTA 18% flow in removing the Ca(OH)2 using CFD analysis. Methods: This research was descriptive. Cleanliness of the root canal wall from Ca(OH)2 medicament using EDTA 18% irrigation was analysed using the CFD method with test specimens in the form of resin blocks made according to the characteristics of the root canal. The irrigation needle used was side-vented with a position of 3 mm from the apical tooth. Stage analysis of root canal geometry was performed using Computational Fluid Dynamics (CFD) analysis to observe the characteristics of irrigation solutions in root canals in 3D. Results: The streamlined characteristics of EDTA 18% irrigation solution showed a unique behaviour due to the features of the side-vent shaped irrigation needle. Irrigation flow in the crown area of the inlet (side-vented irrigation needle) showed low velocity so that the fluid flow when exiting the inlet was more towards the apical than the outlet (root canal orifice). Conclusion: Velocity and wall shear stress of EDTA 18% showed the results validation conformity between experimental and CFD, that the maximum velocity of EDTA 18% is 19 ms-1 and EDTA 18% wall shear stress is 1.56 KPa for calcium hydroxide removal observed from the CFD study. Keywords: Computational fluid dynamics, EDTA 18%, calcium hydroxide (Ca(OH)2), velocity, wall shear stress

Introduction: Dental alginate impression material is the most common material used in dentistry. However, dental alginate waste (DAW) is one of the causes of the increasing number of dentistry and medicinal wastes. This research was aimed to discover the effect of dental alginate impression waste as additional fertiliser on the plant yields by determining the weight of cauliflower crop, and towards the quality of soil by determining the soil pH (Ultisol® Jatinangor). Methods: The experiment was using a randomised block design with 4 treatments and 7 times replications. The treatment consisted of A0 (0% DAW as control), A1 (0.01% DAW), A2 (0.1% DAW), and A3 (1% DAW). Results: The weight of cauliflower after addition of DAW in group A0 was 72.78; A1 was 139.82); A2 was 130.69; and A3 was 60.72). While the pH soil in group A0 was 5.92; A1 was 6.07; A2 was 6.02; and A3 was 6.26. The treatment in the A1 and A2 groups were found as the significant doses that able to increase the cauliflower weight for consecutively 1.92 times and 1.80 times compared to the control group, while on the soil quality improvement (soil pH), the addition of DAW was not significantly affected. Conclusion: It can be concluded that the addition of dental alginate waste at the dose of 0.01% and 0.1% increased the weight of cauliflower, but has no significant effect on the soil quality.

Introduction:Clinical assessment of complete denture by the dentists may differ from the patient’s satisfaction. Dentists will prioritise the clinical aspects of dentures, while patients will prioritise more on their satisfaction. The purpose of this study was to determine the relationship between the stability and bearing area of maxillary and mandibular denture towards the complete denture wearers satisfaction. Methods: This study was a cross-sectional study with purposive sampling method. The subject of this study was as much as 30 people. The research was conducted in each patient’s house to obtained more honest review of the patient’s satisfaction towards their complete dentures without being affected by any clinical environment, and in accordance to the information of their medical records. All the subjects were interviewed using a questionnaire before a clinical evaluation was conducted. The test analysis used was the Fisher test. Clinical examination was used to assess denture stability and bearing area. Evaluation of the patient’s satisfaction level was performed using a questionnaire regarding mastication and comfort. Results:There was a significant association between the clinical evaluation towards the patient’s satisfaction level which were the stability of maxillary denture towards mastication (p = 0.012); and mandibular denture towards mastication (p = 0.029). Whereas no relationship found between maxillary denturebearing area towards comfort (p = 0,051) and mandibular denture-bearing area towards comfort (p =0,547).Conclusion:Stability of maxillary and mandibular denture affected the patient’s mastication satisfaction, whereas bearing area of maxillary and mandibular denture was not affected the patient’s comfort satisfaction.

Introduction: Burkitt’s lymphoma (BL) is one of the tumours with high malignancy and rapid cell growth, derived from B-cell lymphoma. BL typically found in children at dengue-endemic and HIV-AIDS areas with low socioeconomic levels. This study was aimed to analyse the induction of apoptosis and the suppression of tumorigenesis of oral Burkitt’s lymphoma (Raji) cells using docetaxel hydrate in vitro and in vivo. Methods: In the present study, the pure experimental laboratory with post-test only control group design was carried out. Raji cell cultures were incubated with docetaxel hydrate by doses of 0, 1.25 x 10-2, 2.5 x 10-2, and 5.0 x 10-2 M; and IC50 carboplatin (3.1 x 10-6 M) as a positive control. Induction of apoptotic was analysed by double staining of acridine orange-ethidium bromide. Tumorigenesis assay was performed by inoculating Raji cells in nude mice flanks at 1 x 106 cells/mice. Tumour treatment was delivered by various doses of docetaxel hydrate peroral. Results: Apoptosis cells were significantly increased in Raji cells treated with docetaxel hydrate by doses of 2.5 x 10-2 and 5.0 x 10-2 M. The tumour volume in mice given doses of 2.5 x 10-2 and 5.0 x 10-2 M was markedly decreasing compared to control (dose of 0). Conclusion: Docetaxel hydrate has a high antitumour potency by inhibiting tumorigenesis and increasing apoptosis of Burkitt’s lymphoma cells.

Introduction: Tooth discolouration is the most common esthetic problems in dentistry. Direct composite veneer is an adjunctive therapy for severe teeth discolouration by attaching to the tooth surface using an acid etching and dental bonding agent. In several cases of severe discolouration, it is required to have certain preliminary treatments such as bleaching prior to the placement of the composite veneer. However, bleaching agents are able to lead the enamels morphology and microstructure alteration by inhibiting the polymerisation bonding thus affecting the veneer adhesion. This study was aimed to determine the tensile bond strength of direct composite veneers between the V and VII generation dentin bonding agent after extracoronal bleaching. Methods: This study was an experimental laboratory of as much as 32 human permanent maxillary central incisors were divided into 4 groups. Group 1 was treated with extracoronal bleaching and bonded with the V generation bonding nanohybrid composite. Group 2 was treated with extracoronal bleaching and bonded with the VIII generation bonding nanohybrid composite. Group 3 was only bonded with the V generation bonding nanohybrid composite. Group 4 was only bonded with the VIII generation bonding nanohybrid composite. All samples were immersed in artificial saliva then incubated at the room temperature for 24 hours. Results: The tensile strength value was determined using the Universal Testing Machine. The ANOVA test results showed significant differences in all four groups (p < 0.05). Conclusion: The VIII generation bonding agent had a higher tensile strength than the V generation.

Introduction: The soft tissue aspect in orthodontics treatment has gained attention in the last few years. The soft tissue profile is said to reflect the underlying skeletal profile, which causes a convex profile in patients with class II skeletal malocclusion. This research was aimed to determine the changes in the soft tissue facial profile of class II skeletal malocclusion patients with retrognathic mandible after twin block treatment. Methods: The type of research used in this study was retrospective descriptive research with paired t-test. The population was children aged 10-13 years old with class II skeletal malocclusion that were treated with twin block appliance in the Faculty of Dentistry Universitas Padjadjaran, Indonesia. The results of soft tissue changes before and after twin block treatment were compared. Results: There was an insignificant increase in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment (p > 0.05). Whereas, Holdaway’s H-angle was decreasing and Merrifield’s Z-angle was increasing after twin block treatment, with statistically significant difference (p < 0.05). Conclusion: There was a decrease of H-angle, indicates a reduction in facial convexity and improvement of the facial profile after twin block treatment, but no difference in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment.

Introduction: Salvadora persica, also known as miswak (Kayu sugi), has been used as natural toothbrushing compound for centuries. Many research suggested that it contains medically beneficial properties such as abrasives, antiseptics, astringent, detergent, enzyme inhibitors, and fluoride. The objective of this study was to assess the efficacy of miswak containing toothpaste on dental plaque accumulation. Methods: The total of 30 subjects consisted of male students of Bandung Institute of Technology, aged between 18 – 26 years old. The plaque value was measured using the Turesky Gilmore & Glickman Index Modification of Quigley & Hein at baseline (day 0), day 1, day 3, and day 7. Commercial toothpaste (Pepsodent®) was used as the control group in this pre and post-test designed, single-blind study. Results: After analysed using the paired t-test, the data showed that the mean plaque index of respondents using miswak and non-miswak containing toothpaste from baseline until day 7, were 1.70/1.19 and 1.61/1.44 respectively (p < 0.05). The mean plaque index reduction of respondents using miswak and non-miswak containing toothpaste from baseline until day 7, were 0.39 and 0.25 respectively (p = 0.00). Conclusion: Both kinds of toothpaste were able to reduce plaque, but miswak containing toothpaste was found to be more effective in reducing dental plaque accumulation.

Introduction: Dentists are at risk of Hepatitis B, Hepatitis C, and HIV infections in their professional practices. The purpose of this study was to determine the knowledge level, attitude, and behaviours of the Turkish dentists regarding contamination and prevention of Hepatitis B, Hepatitis C, and HIV infections. Methods: After receiving the required ethical and administrative approvals, a 33-item digital survey was applied within the context of the present study, and carried out amongst 58 dentists. Results: According to the results of this study, the knowledge level did not vary between different demographic features (p ˃ 0.05). However, the dentists’ attitude and behaviours were different. Post-exposure attitude towards Hepatitis B, Hepatitis C, and HIV infection did not vary between different demographic features (p ˃ 0.05). Female dentists who received education regarding infectious diseases more often got health check in case of injury (p ˂ 0.05). Female dentists felt more concerned than male dentists when they were treating infected patients, and they were more often using protective barriers (p ˂ 0.05). Dentists who were working at the university hospital and public hospital mostly had their Hepatitis B vaccinations more often than private clinics, also, dentists in university hospitals more often reported prefer to treat infected patients (p ˂ 0.05). Dentists who did not receive any education have reported that dental treatment of infected patients should be performed in specialised clinics (p ˂ 0.05). Conclusion: The Turkish dentists’ knowledge level, attitude, and behaviour were different. According to the findings of this study, efficacious education programs should be prepared for dentists to establish a positive attitude towards Hepatitis B, Hepatitis C, and HIV infected patients.Keywords: Dentists, Turkish, Hepatitis B virus, Hepatitis C virus, HIV.

The most common chronic inflammation involved dental and oral tissue is gingival polyp, pulp polyp, and fibroma that are proliferative non neoplastic and neoplastic condition. Chronic inflammation will induce cells and vascular proliferation as well as biological nature lesion. Previous study revealed that increase macrophage followed by increase angiogenesis intensity. Increase angiogenesis or vascular proliferation indicates progressive growth in form of proliferative non neoplastic or neoplastic disease outside of their easily bleeding clinical features. This study evaluated macrophage and angiogenesis intensity and their correlation within such oral lesions. Samples used are of oral mucosa excision with clinical diagnose of gingival polyp (n=3); pulp polyp (n=3); and fibroma (n=3). Macrophage was detected using immunostaining with CD68 antibody resulted in brown staining cell membrane under light microscope while angiogenesis intensity evaluated as number of blood vessels. The results showed there was mild positive correlation of angiogenesis intensity and CD68+ as macrophage marker with r=0.31. The angiogenesis intensity showed significant differences (p<0.05) with the highest was in pulp polyp (12.00) followed by fibroma (11.81) and gingival polyp (9.67), however there was no significant difference between non neoplastic lesion (pulp polyp) and neoplastic lesion (fibroma). The CD68+ expression showed no significant differences (p=0.102>0.05) with the highest was in fibroma (51.32±31.64%) followed by non neoplastic pulp polyp (45.82±15.94%) and gingival polyp (29.98±13.51%). This result was in accordance with the biological properties of lesions from the aspect of angiogenesis and macrophage intensity that can be used as parameter for determining the growth and prognosis of lesion.
