Background: Tooth extraction is generally followed by alveolar ridge resorption that later can cause flat ridge. Aloe vera have biogenic stimulator and hormone activities for wound healing. Purpose: This study was aimed to know osteoblast activities in alveolar bone after induction of Aloe vera and XCB combination. Methods: Fifty four of Cavia cabaya were divided into three main groups. Group I was control group. Group II was filled with xenograft concelous bovine (XCB) and group III was filled with the combination of Aloe vera gel and XCB. Then, each group was divided into three sub groups according to timing, they are 14, 30, and 60 days after tooth extraction and application. Histology and morphology examination were performed on the harvested specimens. Results: There were significant differences between the control group and the other groups filled with the combination of Aloe vera and XCB. Conclusion: In conclusion, the application of Aloe vera gel and xenograft combination decrease the number of osteoclast and increase the number of osteoblast in post tooth extraction alveolar bone structure indicating the new growth of alveolar bone.Latar belakang: Pencabutan gigi pada umumnya selalu diikuti resopsi tulang alveolar, sehingga bila terjadi dalam waktu yang lama ridge akan menjadi flat. Aloe vera adalah bahan stimulasi biogenik dan mempunyai aktivitas hormon untuk proses penyembuhan luka. Tujuan: Tujuan dari penelitian ini adalah untuk mengetahui aktivitas osteoblas pada tulang alveol dengan pemberian kombinasi Aloe vera gel dan xenograft concelous bovine (XCB). Metode: Lima puluh empat ekor Cavia cabaya, dibagi menjadi 3 kelompok besar, kelompok pertama adalah kelompok kontrol yaitu hanya dilakukan pencabutan saja tanpa perlakuan, kelompok ke-2 yaitu kelompok yang setelah dicabut diberi XCB saja dan kelompok ke-3 yaitu kelompok yang setelah pencabutan diberi kombinasi Aloe vera gel dengan XCB pada luka bekas pencabutan gigi. Kemudian masing-masing kelompok besar ini dibagi lagi berdasarkan waktu menjadi 3 sub kelompok yaitu setelah 14, 30 dan 60 hari. Kemudian dilakukan pemeriksaan histology dan morfologi pada specimen hewan coba. Hasil: Terdapat perbedaan bermakna antara kelompok kontrol dan kelompok yang diberi kombinasi Aloe vera dan XCB. Kesimpulan: Disimpulkan bahwa pemberian kombinasi Aloe vera gel dan xenograft menyebabkan penurunan jumlah osteoklas dan peningkatan jumlah osteoblas pada struktur tulang alveol pasca pencabutan gigi yang menunjukkan adanya pertumbuhan tulang alveol baru.

Background: In the field of dentistry, alveolar bone damage can be caused by periodontal disease, traumatic injury due to tooth extraction, cyst enucleation, and tumor surgery. One of the ways to regenerate the bone defect is using graft scaffold. Thus, combination of chitosan and collagen can stimulate osteogenesis. Purpose: The aim of this study was to examine the potential of chitosan combined with chicken shank collagen on bone defect regeneration process. Method: Twelve Rattus norvegicus were prepared as animal models in this research. A bone defect was intentionally created at both of the right and left femoral bones of the models. Next, 24 samples were divided into four groups, namely Group 1 using chitosan – collagen scaffold (50:50), Group 2 using chitosan collagen-scaffold (80:20), Group 3 using chitosan scaffold only, and Control Group using 3% CMC-Na. On 14th day, those animals were sacrificed, and histopathological anatomy examination was conducted to observe osteoclast cells. In addition, immunohistochemistry examination was also performed to observe RANKL expressions. Result: There was a significant difference in RANKL expressions among the groups, except between Group 3 using chitosan scaffold only and control group (p value > 0.05). The highest expression of RANKL was found in Group 1 with chitosan – collagen scaffold (50:50), followed by Group 2 with chitosan-collagen scaffold (80:20). Moreover, there was also a significant difference in osteoclast generation, except between Group 1 using chitosan – collagen scaffold (50:50) and Group 2 using chitosan-collagen scaffold (80:20), p value < 0.05; and between Group 3 using chitosan scaffold only and control group, p value > 0.05. Less osteoclast was found in the groups using chitosan – collagen scaffold (Group 1 and Group 2). Conclusion: Combination of chitosan and chicken shank collagen scaffold can improve regeneration process of bone defect in Rattus novergicus animals through increasing of RANKL expressions, and decreasing of osteoclast.

Background: The high prevalence of early childhood caries still becomes a major health problem. It is because children prefer to consume sweet foods, which are also cariogenic. The oral mucosa is a mirror of general health or any systemic disease which usually shows visible symptoms in the oral cavity. Dental caries in children is often related to the socioeconomic characteristics of the parents. Some references suggest that there is a relationship between the socioeconomic status with the incidence of caries. Purpose: The purpose of this study was to examine the relationship of socioeconomic characteristics of the parents with the risk prediction of early childhood caries by using cariogram approach to the elementary school students in Wonosobo. Method: The research is an observational analytic study with cross-sectional approach survey method. The research sampling uses proportional random sampling with 201 respondents of fifth graders. The socioeconomic status is measured through questionnaires, while the risk prediction of early childhood caries is measured by using cariogram. The research data analysis uses Spearman rank. Result: The results of the study show that the socioeconomic characteristics of the respondents’ parents mostly belong in the middle category as many as 145 respondents (72.1%), lower category as many as 31 respondents (15.4%) and in the upper category as many as 25 respondents (12.4%). Prediction of the respondents avoiding early childhood caries is 55%, while the prediction of the respondents being risked of having early childhood caries is 45%. The results of data analysis show that the relationship between the socioeconomic characteristics of the respondents’ parents and the risk of having early childhood caries for the respondents is p<0.05. Conclusion: There is a relationship between the socioeconomic characteristics of the respondents’ parents with the early childhood caries, which shows that the higher the socioeconomic status of the parents, the lower the risk of the respondents from having early childhood caries.

Background: Exposure of metals among dental technicians that come from the working environment can lead to the formation reactive oxygen species (ROS). ROS can cause mutations in the p53 gene (p53). The mutation is transversion mutation GuanineThymine. p53 mutations can lead to low expression of the wild-type p53 protein (p53). Wild-type p53 involved in many biological processes such as regulation of genes involved in cell cycle, cell growth after DNA damage, and apoptosis. However, exposure to metals among dental technicians can be prevented through the use of personal protective equipment (PPE) during work. Purpose: The purpose of this study was to analyze the correlation between the use of personal protective equipment to wild-type p53 protein levels among dental technicians in Surabaya. Method: This study was observational analytic with cross sectional approach. 40 samples were taken by random sampling. Data were retrieved through interviews and observations. Wild-type p53 was analyzed from saliva with indirect ELISA method. Analysis of data used Kolmogorov Smirnov normality test and a Pearson correlation test. Value significance was p<0.05 (95% confidence level). Result: There was a significant association between the use of personal protective equipment with wild-type p53 levels with p=0.002 Conclusion: The use PPE properly is positively correlated with the wild-type p53 protein levels of dental technicians in Surabaya.

Background: Traumatic ulcers in patients with diabetes mellitus may experience delayed healing despite their diabetic condition being controlled. Liquid smoke coconut shell containing phenolic compounds can potentially accelerate the healing process. One healing process indicator is the increased number of fibroblasts, another being the increased amount of collagen. Purpose: This study aimed to analyze the amount of collagen in traumatic ulcers in diabetics after application of liquid smoke coconut shell. Methods: Alloxan was induced in twenty-four male Wistar rats as models of diabetes mellitus. A traumatic 10 mm ulcer was made along the labial fornix incisive inferior with a round, stainless steel blade before liquid smoke coconut shell and benzydamine hydrochloride (as the control) was administrated once a day. A biopsy of the labial fornix incisive inferior was subsequently performed after the topical application for 5 and 7 days. Histological assessment was conducted to analyze the amount of collagen by means of Masson Trichome staining. Results: Histologically, the topical application of liquid smoke coconut shell for 5 days significantly increased the amount of collagen, higher than that of benzydamine hydrochloride as the control (p=0.006) (p<0.05). Meanwhile, the topical application of liquid smoke coconut shell for 7 days made the concentration of collagen no significantly different from that of benzydamine hydrochloride as the control (p=0.156) (p>0.05). Conclusion: Liquid smoke coconut shell applied for 5 days increase the amount of collagen in traumatic ulcers in diabetic patients.

Background: Over 500.000 of the 2,3 million surgical treatments requiring bone grafting procedures that are performed annually are likely to be necessitated by or will result in bone defects that will not regenerate. Treatment to regenerate new tissues is needed, especially for hard tissue repair, which not only relies on a natural osseointegration process, but also requires a physical support to guide the differentiation and proliferation of cells into the targeted functional tissue. Chitosan and collagen extracted from chicken feet combinations are expected to enhance the bioactive surface and provide mechanical strength as a bone graft scaffold. Purpose: The aim of this study was to investigate the role of chitosan and collagen scaffold synthesized from chicken feet applications to increase the expression of Osteoprotegerin (OPG) and osteoblast cells on the fourteenth day of bone healing. Methods: Eighteen three-month old, adult, male, Rattus novergicu strain rodents with a body weight ranging from 200-350 g were kept under controlled environmental conditions. The mice were randomly divided into three groups consisting of three subjects, each treated with collagen, chitosan, chitosancollagen combination (50:50) scaffolds. On the 14th post-treatment day, three members of each group were sacrificed. Examination of Osteoprotegerin (OPG) expression was conducted by means of immunohistochemistry staining with anti-OPG polyclonal antibodies. Meanwhile, osteoblast cell examination was performed by means of hematoxilin-eosin (HE) staining. Results: The mice treated with collagen and a chitosan-collagen combination scaffold presented an increase in the expression of Osteoprotegerin (OPG) and the number of osteoblast cells respectively. Conclusion: A combination of chitosan-collagen (50:50) scaffold extracted from chicken feet increased the expression of OPG and the number of osteoblasts in the bone healing process. The combination scaffolds demonstrated the highest OPG expression and number of osteoblasts compared to the other groups.

Background: A traumatic ulcer represents one of the most prevalent disorders affecting the oral cavity. Ulceration of the oral cavity potentially results in secondary infection requiring topical medication which involves the use of antiseptics to accelerate wound healing. Previous research has shown that Mauli banana (Musa acuminata) stem extract (MBSE) contains bioactive material from terpenoid saponin present in Ambon bananas. The terpenoid saponin in Ambon banana stems will be captured by a G protein receptor in the macrophages, subsequently producing a protein kinase C that activates nuclear factor kappa beta (NF-κB). This increases both the activity and number of macrophages. Purpose: To analyze the expression of NF-κB (p50) in traumatic ulcers as an effect of MBSE. Methods: A true experimental design with a post-test only control group. It involved 40 male Rattus norvegicus strain rats as traumatic ulcer models divided into four groups: the negative control group administered gel, and the other treatment groups administered 25%, 37.5% and 50% ethanol extracts of MBSE gel respectively. A biopsy was performed on days 3 and 5. The preparation was produced to analyze the expression of NF-κB (p50) by means of immunohistochemistry examination. Results: There was a significant difference (p<0.05) in NF-κB (p50) expression (p=0.005) following MBSE gel administration of 37.5% concentration on day 3 compared to day 5. Conclusion: It can be concluded that MBSE gel topical application can increase expression of NF-κB (p50) in traumatic ulcer healing.
