Acrylic resin is the most commonly used denture base material. However, it has a shortage of being easily broken. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to compare the transversal strength of PE and glass fibers from denture plate acrylic resin repair material. The experiment involved 32 plates of heat cure acrylic with the dimensions of 65 mm x 10 mm x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. Subjects were divided into 2 groups, each group containing 16 plates. Group I was reinforced with PE fiber and Group II was reinforced with glass fiber. All plates were soaked in distillation water for one day at 37 °C. Plates were tested for transverse strength with universal testing machine and all data were analyzed with independent t-tes at 95% confidence level. Macro photo analysis was used to observed the bond failure on fiber and resin. The mean of transverse strength (MPa) denture plate acrylic resin repair material reinforced with PE fiber was (67.38 ± 4.31) MPa, while glass fiber was (93.61 ± 6.14) MPa. Independent t-tes showed that type of fiber had a significant effect (p<0.05). Thus, it is possible to conclude that addition of glass fibers in denture plate acrylic resin repair material increased the transverse strength and made it stronger than those added with PE fibers.

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic bacterium, which could aggressively infect immunocompromised patients and thus, cause high mortality rate. In addition, P. aeruginosa in oropharynx could be aspirated and cause ventilator associated pneumonia. Royal jelly is one of bee’s products that has been used for therapeutic needs including antibacteria. Adherence factor of P. aeruginosa were flagelum, pili and lectin. The aim of the study was to determine the effect of royal jelly to P. aeruginosa adhesion. Suspension of P. aeruginosa (ATCC® 27853) was incubated at 37 °C for 18 h. Treatment groups were exposed to royal jelly with several concentrations, 2%, 4%, 6%; while distilled water was being used as negative control. Bacterial adhesion test was determined using spectrophotometer λ = 600 nm to measure optical density values of adhered bacterial suspension in tubes. The result of one-way ANOVA showed significant differences (p<0.05) of optical density values among groups indicating that royal jelly affected the bacterial adhesion. LSD results showed significant difference of optical density values between 2%, 4%, and 6% royal jelly compared to distilled water. Six percent of royal jelly had the least optical density value compared to the other groups. In conclusion, royal jelly has the ability to decrease adhesion of P. aeruginosa. Six percent of royal jelly has better ability to decrease adhesion of P. aeruginosa than other concentrations.

Periodontitis is a periodontal disease involving the gingiva, periodontal ligament, cementum, and alveolar bone due to an inflammatory process. Virulence factors of periodontopathogens and inflammatory responses in periodontitis can stimulate nuclear factor-kappa B (NF-κB) activity. Charantoside c and Momordicosides g in bitter gourd prevent NF-κB activation stimulated by TNF-α in HepG2 cells. This study aims to determine the effect of bitter gourd fruit (Momordica charantia) ethanolic extract as an anti-inflammatory substance on the level of inflammatory infiltrates and the number of cells that experience NF-κB activation in the periodontitis model. Eighty male Wistar rats were divided into 5 groups. The mandibular incisors were ligated for 14 days to induce periodontitis. Each group was given Momordica charantia extract of 500 mg/kg BW, 250 mg/kg BW, and 100 mg/kg BW; ibuprofen 100 mg/kg BW; and aquades orally using oral gavage on the day 14. Rat necropsy was carried out on day 1, 3, 5, and 7 after giving the substances. Taking out the lower jaw was done to make tissue preparations followed by staining them with hematoxylin eosin (HE). Immunohistochemicalanalysis was performed to observe cells that were positive for NF-κB activation. The results showed a decrease in the density of inflammatory infiltrates in all groups, except for those given aquades. The number of inflammatory cells ofneutrophils, macrophages, and lymphocytes that experienced NF-κB activation showed the most effective decrease in the group of Momordica charantia 500 mg/kg BW, on the 7th day. The conclusion of this study is that ethanolic extractof Momordica charantia has an anti-inflammatory effect and prevents the activation of NF-kB in rat gingival induced by periodontitis. The highest effect was found at a dose of 500 mg/kg BW on day 7 after giving of extracts.

Indonesians have been using herbal medicines for a long time to cure some illnesses. Carica papaya L is an example of an herb that contains papain enzymes, saponins, lysozymes, lipases, flavonoids, polyphenols and vitamin C. These ingredients are believed to be beneficial for the wound healing process. The purpose of this study was to determine the effect of topical application of ethanolic extract of Carica papaya L to the healing process of rat mouth ulcer. Subjects were 32 Wistar rats divided into 2 groups (control group and treatment group), each group containing 16 rats. All subjects were made to suffer from ulcers using glacial acetyl acid applied for 40 seconds in the buccal mucosa. Treatment group was treated with papaya leaf ethanolic extract on ulcers twice a day using microbrush, while the ulcer in the control group was not treated with the extract. The ulcerated tissue was biopsied and stained with H&E. Observations were performed on the day 0, 3rd, 7th and 12th on HE slides. Data were observed by looking at three indicators of wound healing i.e. macrophage, angiogenesis and re-epithelisation. Number of macrophages and angiogenesis were analyzed using two-way ANOVA. Data of epithelial thickness were analyzed using Kruskal-Wallis test. The post hoc test in the treatment group and the control group on day 0 showed results of p = 1.00. On day 3, day 7 and day 12, the result of p was <0.05. In the treatment group on day 0 compared to the treatment group on the 3rd, 7th, 12th day, the results were p<0.05. In the treatment group on the 3rd day compared to the 7th and 12th days the results were p>0.05. The treatment group on the 7 day compared to the treatment group on the 12 day had p>0.05. In the control group, on day 0 compared to day 3, the results of p>0.05, while the control group day 0 with day 7, 12 had a result of p<0.05. The control group on the 3rd day was compared with the 7th day. The 12th also had a result of p<0.05. The comparison between the 7 day control groups showed p of >0.05. These data suggest that the papaya leaf ethanolic extract could accelerate the healing of oral ulcer on the buccal mucosa of wistar rats.

Treatment of infrabony pocket makes use of bone graft material demineralized freeze dried bone allograft (DFDBA) from different individuals which has undergone demineralization process and it is osteoinductive. Enhancement of growth factor was done by adding platelet rich fibrin (PRF) and platelet rich plasma (PRP). PRP is activated with an addition of calcium chloride CaCl2) to form gel. The method used to apply the bone grafting material is open flap debridement OFD). This research aimed to reveal the differences in the results of infrabony pocket treatment using PRF and PRP gel with an addition of DFDBA. The sample was taken from 20 infrabony pocket points divided into 2 groups, 10 infrabony pocket were treated with OFD+DFDBA+PRF and the other were treated with OFD+DFDBA+PRP gel. Pocket depth (PD) was measured on the baseline and the first and third month after treatment. Alveolar bone height was measured using cone beam computed tomography (CBCT) radiograph on the baseline to the third month after treatment. The results of this research showed that there was difference in the results of infrabony pocket treatment using PRF and PRP gel with an addition of DFDBA which could be observed from a reduction in PD from the baseline, month 1 and month 3 as well as reduction in alveolar bone height from the baseline to month 3. This research concluded that infrabony pocket treatment PRF application yields better results than PRP gel application in terms of PD and alveolar bone height reduction.

Exclusive breastfeeding during the first six months of life is extremely important for the development of the dentocraniofacial structure, occlusion, breathing and swallowing during childhood. The prevalence severity rate of malocclusion in children who were breastfed is lower than those who were bottle-fed. The aim of this study is to evaluate the associations of infant feeding patterns on the deciduous second molar relationship in preschool aged children (3-5 years old children) of selected preschools in and around Medan Selayang. This study used analytic cross-sectional study design as the research method. The sampling was carried out by purposive sampling technique. This study involved 130 children aged 3-5 years as the sample, who consisted of two groups, the exclusively breastfed group and the bottle-fed group with the inclusion criteria of the children having a good oral and dental health. The result is statistically analyzed using Chi Square with a significance level of p<0.05. There was a significant difference between children who were breastfed and those who were bottle-fed. Children who were breastfed mostly had mesial step (55, 4%), followed by distal step(27.7%) and flush (16.9%), while those children who were bottle-fed mostly had distal step (46.2%), flush (33.8%), and mesial steps (20%). Based on Chi Square test, it is shown that there is a significant relationship between infant feeding patterns to primary molar relationships (p<0.001).

Glass fiber non-dental has a similar composition to E-glass fiber dental that commonly used as fiber reinforced composite (FRC) materials in resin bonded prosthesis. Fiber effectiveness can be determined by the length and the position. The aim of this study was to examine the effect of glass fiber non dental’s length and position on the flexural strength of FRC in resin bonded prosthesis. This study has been done used 36 FRC samples with beam shaped (15 mm x 2 mm x 2 mm). Fiber reinforced composite samples were consisted of 9 groups (a combination between length: 4 mm, 6 mm, and 12 mm and position: compression, neutral, tension zone). The flexural strength was tested by universal testing machine and statistically analyzed using two-way ANOVA (p<0.05). The result showed that the lowest (compression, 4 mm) and the highest (tension, 12 mm) flexural strength were 104.30 ± 13.90 MPa and 166.18 ± 8.59 MPa. The two-way ANOVA test showed that variation of position, length, and interaction between placement-length had a significant effect on the flexural strength (p<0.05). The conclusion of this study was fiber position on compression zone with 4 mm length had the lowest flexural strength. In addition, fiber position on tension zone with 12 mm length had the highest flexural strength.
