Abstract

Background: Porphyromonas gingivalis as a major etiology of periodontal disease can produce virulence factor, lipopolysaccharide/LPS, which is expected to play a role in the intrauterine fetal growth. Trophoblast at the maternal-fetal interface actively participates in response to infection through the expression of a family of natural immune receptors, toll-like receptor (TLR). Purpose: the aims of study were to identify endotoxin concentration in maternal blood serum of Porphyromonas gingivalis-infected pregnant rats, to characterize the TLR-4 expression in trophoblast cells, and to determine its effect on fetal growth. Methods: Female rats were infected with live-Porphyromonas gingivalis at concentration of 2 x 109 cells/ml into subgingival sulcus area of the maxillary first molar before and/or during pregnancy. They were sacrified on 14th and 20th gestational day. Fetuses were evaluated for weight and length. Endotoxin was detected by limulus amebocyte lysate assay in the maternal blood serum. The TLR-4 expression in trophoblast cells was detected by immunohistochemistry. <span style="font-family: Tribune-Bold; font-size:

Abstract

The bone defect due to tooth extraction contributes the most cases reported in the aspects of oral surgery. The defect can be preventively managed by adding powder bone matrix intended for augmentation which eventually induces the formation of new bones. This hard tissue wound healing is preceded by the presence of collagen fibers. The aim of this study was to determine the density of collagen fiber in the alveolus mandibular bone of rabbit which was augmented using powder demineralized bone matrix (DBM) post incisivus extraction. Twenty four male rabbits aged 2.5–3 months weighed 900–1,100 grams were randomly divided into two groups. The treated rabbits were augmented with DBM after the incisivus extraction on mandible. The mucosa was then sutured. On the other hand, the controlled rabbits received similar treatments with those of the treated rabbits except there was no augmentation of DBM. Decapitation of treated and controlled rabbits was made on day 5, 7, 10, and 14 days post surgery, each with three rabbits. Mandibles were cut, decalcified, and imbedded in paraffin block. The staining was done using Mallory. Significant differences in the density of collagen were noted on day 10 and 14 post surgery, indicating that powder demineralized bone matrix successfully induced the stimulation of collagen.

Abstract

Background: Dental caries with necrotic pulp is a multifactorial disease that attacks enamel involving tooth pulp. The anaerobic bacteria infection in the pulp chamber could induce the formation of periapical granuloma. However, the presence of the most frequently anaerobic bacteria identified in apical periodontitis, Porphyromonas gingivalis and Prevotella intermedia, in periapical granuloma have not been confirmed. Purpose: The aims of study were to determine the presence of Porphyromonas gingivalis and Prevotella intermedia in dental caries with necrotic pulp and to determine its relation to periapical granuloma. Methods: Thirty-six patients of dental caries with necrotic pulp in Dr. Moewardi General Hospital in Surakarta, Indonesia were involved and classified into two groups, the group of patients with periapical granuloma and the group of patients without periapical granuloma. The caries tooth was extracted, and the chronic periapical tissue was swabbed and cultured on blood agar medium in anaerobic condition. The bacterial DNA was extracted from the positive cultures and subjected for Polymerase Chain Reaction (PCR). Results: Periapical granuloma was more likely found in women (OR 5.5, 95% CI=1.277-23.693; RR 2.5, 95% CI= 1.025-6.100). Black colonies bacteria were associated with periapical granuloma (OR 2.2, 95% CI=0.517-9.594; RR 1.5, 95% CI=0.655-3.623). Porphyromonas gingivalis and Prevotella intermedia were detected in group with or without periapical granuloma, however, only Prevotella intermedia was associated with periapical granuloma (OR 1.6, 95% CI=0.418-5.903; RR 1.3, 95% CI=0.653-2.393). Conclusion: The presence of Porphyromonas gingivalis and Prevotella intermedia in periapical granuloma were confirmed, however, only Prevotella intermedia were associated with periapical granuloma.Latar belakang: Karies gigi dengan pulpa nekrosis adalah penyakit multifaktorial yang menyerang enamel hingga ruang pulpa gigi. Infeksi bakteri anaerob di pulpa nekrosis dapat menginduksi pembentukan granuloma periapikal. Namun, keberadaan bakteri anaerob yang paling banyak ditemukan di periodontitis apikal, Porphyromonas gingivalis dan Prevotella intermedia, di granuloma periapikal masih perlu diteliti . Tujuan: Penelitian ini bertujuan meneliti keberadaan bakteri Porphyromonas gingivalis dan Prevotella intermedia, di karies gigi dengan pulpa nekrosis dan menganalisis kaitannya dengan granuloma periapikal. Metode: Tiga puluh enam pasien karies gigi dengan pulpa nekrosis di Rumah Sakit Umum Dr. Moewardi di Surakarta Indonesia dilibatkan dan diklasifikasikan dalam dua kelompok yaitu kelompok pasien dengan granuloma periapikal dan kelompok pasien tanpa granuloma periapikal. Gigi karies diekstraksi dan jaringan periapikal kronis diusap dan dikultur di media agar darah dalam kondisi anaerob. DNA bakteri diekstrak dari kultur yang positif dan dilakukan pemeriksaan dengan Polymerase Chain Reaction (PCR). Hasil: Granuloma periapikal lebih banyak ditemukan pada wanita (OR 5,5, 95% CI= 1,277-23,693; RR 2,5, 95% CI= 1,025-6,100). Koloni bakteri berwarna hitam diasosiasikan dengan granuloma periapikal (OR 2,2, 95% CI= 0,517-9,594; RR 1,5, 95% CI= 0,655-3,623). Porphyromonas gingivalis dan Prevotella intermedia terdeteksi di jaringan karies dental dengan atau tanpa granuloma periapikal, namun hanya Prevotella intermedia yang diasosiasikan dengan granuloma periapikal (OR 1,6, 95% CI= 0,418-5,903; RR 1,3, 95% CI= 0,653-2,393). Simpulan: Porphyromonas gingivalis dan Prevotella intermedia ditemukan di granuloma periapikal, namun hanya Prevotella intermedia yang terkait langsung dengan granuloma periapikal.

Abstract

Background: The increasing of osteoblast activities during bone formation will be accompanied with the increasing expression of alkaline phosphatase enzyme (ALP). ALP can be obtained from clear fluid excreted by gingival crevicular fluid (GCF). Bone turnover, especially bone formation process, can be monitored through the expression of ALP secreted by GCF during orthodontic treatment. Thus, retention period is an important period that can be monitored through the level of bone metabolism around teeth. Purpose: This research were aimed to determine the relation of distance change caused by tooth relapse and ALP activities in gingival crevicular fluid after orthodontic; and to determine ALP as a potential biomarker of bone formation during retention period. Methods: Lower incisors of 25 guinea pigs were moved 3 mm to the distally by using open coil spring. Those relapse distance were measured and the gingival crevicular fluid was taken by using paper points to evaluate ALP levels on days 0, 3, 7, 14 and 21 respectivelly by using a spectrophotometer (405 nm). t-test and ANOVA test were conducted to determine the difference of ALP activities among the time intervals. The correlation regression analysis was conducted to determine the relation of distance change caused by the relapse tooth movement and ALP activities. Results: The greatest relapse movement was occurred on day 3 after open coil spring was removed. There was significant difference of the average of distance decrease among groups A1-A5 (p<0.05). It was also known that ALP level was increased on day 3, but there was no significant difference of the average level of ALP among groups A1-A5 (p>0.05). Finally, based on the results of correlation analysis between the ALP level decreasing and the relapse distance on both right and left of mesial and distal sides, it is known that there was no relation between those two variables (p>0.05). Conclusion: It can be concluded that relapse after orthodontic tooth movement occurs rapidly as the teeth are free from orthodontic force. ALP level can be detected through gingival crevicular fluid during relapse by using a spectrophotometer.Latar belakang: Peningkatan aktivitas osteoblas selama pembentukan tulang akan disertai peningkatan ekspresi enzim alkalin fosfatase (Alkaline Phosphatase/ALP). Sumber ALP dapat diperoleh dari cairan bening yang diekskresi celah gingiva gigi yang dikenal sebagai cairan krevikuler gingiva (gingival crevicular fluid/GCF). Bone turnover terutama proses pembentukan tulang dapat dimonitor melalui ekspresi ALP cairan krevikuler gingiva selama perawatan ortodonti. Periode retensi merupakan periode yang penting. Kesulitan memecahkan masalah retensi akan dapat ditangani dengan memonitor tingkat metabolisme tulang disekitar gigi. Tujuan: Penelitian ini bertujuan untuk meneliti perubahan jarak relapse gigi dan aktivitas ALP pada cairan krevikuler gingiva setelah digerakkan secara ortodonti dan potensi ALP sebagai biomarker pembentukan tulang pada periode retensi. Metode: Gigi insisivus bawah 25 ekor marmot digerakkan ke distal menggunakan opencoil spring sampai mencapai jarak ± 3 mm, diukur gerakan relapse gigi dan pengambilan cairan krevikuler gingiva menggunakan paper point untuk dievaluasi kadar ALP pada hari ke 0, 3, 7, 14 dan 21 menggunakan spektrofotometer (405 nm). Analisis t-test dan anova untuk mengetahui perbedaan aktivitas ALP antar interval waktu dan analisis regresi korelasi untuk mengetahui hubungan besarnya jarak relapse dengan aktivitas ALP. Hasil: Pergerakan relapse yang paling besar terjadi pada hari ke 3 setelah opencoil spring dilepas. Terdapat perbedaan rata-rata penurunan jarak antar kelompok A1-A5 yang signifikan (p<0,05). Kadar ALP mengalami peningkatan pada hari ke 3, namun tidak terdapat perbedaan rata-rata yang signifikan kadar ALP antar kelompok A1-A5 (p>0,05). Hasil uji korelasi antara penurunan jarak dengan kadar ALP pada mesial distal gigi baik kanan maupun kiri tidak menunjukkan adanya hubungan kedua variabel (p>0,05). Simpulan: Relapse pada perawatan ortodonti terjadi secara cepat ketika gigi terbebas dari gaya ortodonti. Kadar ALP dapat terdeteksi dari cairan krevikuler gingiva pada pergerakan relapse gigi menggunakan spektrofotometer.

Abstract

Background: Streptococcus sanguinis (S. sanguinis), an oral commensal bacterium, is often implicated in infective endocarditis. Its adherence to the tooth surface is the initial step in dental plaque formation. In addition to the important role of S. sanguinis in systemic disease and antimicrobial resistance, it is necessary to develop methods to control dental plaque formation. Immunoglobulin Y (IgY) has been used to prevent bacterial infection. Purpose: The purpose of this study is to analyze the ability of anti-S. sanguinis IgY antibodies to inhibit S. sanguinis adherence to hydroxyapatite (HA) discs as a model of the tooth surface. Methods: Antibodies were produced by immunizing hens with S. sanguinis suspension. Boosters were given three times following the first injection. An agar gel precipitation test (AGPT) was used to detect the presence of anti-S. sanguinis IgY. A bacterial adherence assay was performed twice to analyze the ability of IgY and the optimal concentration required to inhibit bacterial adherence. Results: The formation of a precipitation line using AGPT confirmed the presence of the antibody. In addition, it was shown that the anti-S. sanguinis IgY antibody could inhibit bacterial adherence to HA. Statistical analysis using One-way ANOVA revealed a significant difference in the optical density (OD) value between the groups (p<0.05). The results of electron microscopy scanning confirmed the quantitative analysis by means of a bacterial adherence test. Conclusion: Anti-S. sanguinis IgY has the ability to inhibit adherence of S. sanguinis to HA discs at an optimal concentration of 30%. The inhibitive effect was stronger in the presence of saliva.

Abstract

Background: One of the composite resin composition is inorganic filler. The production of inorganic filler materials was highly dependent on non-degradable, and nonrenewable fossil fuels. Therefore, natural fibers can be used as substitute for inorganic fillers. One that can be developed is sisal. Purpose: This study aimed to determine the effects of nanosisal filler volume on compressive strength of composite resin. Methods: In this study, composite resins with nano-sized sisal as filler were manufactured and labeled as nanosisal composites. This research processed sisal fibers into nano size and mixed them with Bis-GMA, UDMA, TEGDMA, Champhorquinone (Sigma Aldrich). Nanofiller composite (Z350 XT, 3M, ESPE) was utilized as a control. The 20 samples utilized were divided into 4 groups (each group containing five samples): Group A contained nanosisal composite of 60% filler volume, group B, nanosisal composite of 65% filler volume, group C, nanosisal composite of 70% filler volume and group D, nanofiller composite (Z350 XT, 3M, ESPE). Samples were 2 mm in diameter and 6 mm in height. The sample was tested for compressive strength using a universal testing machine (UTM). Data was analyzed by means of a Kruskal Wallis procedure. Results: The mean of the compressive strength of the nanosisal composite 60% was 16.80 MPa; the nanosisal composite 65% was 10.80 MPa, the nanosisal composite 70% was 7.20 MPa and the nanofiller composite was 7.40 MPa. There was a significant difference in data analysis (p = 0.033; p < 0.05). Conclusion: In this study, the filler volume of nanosisal influenced the compressive strength of a composite resin and the nanosisal filler volume was recomended at 60%.
