Abstract

Retainer dibutuhkan untuk membantu menstabilkan posisi gigi geligi selama proses reorganisasi jaringan periodontal berlangsung. Retainer FRC ortodonsi dikembangkan sebagai alternatif material estetika serta aman bagi pasien alergi terhadap nikel. E-glass fiber lebih sering digunakan sebagai retainer ortodonsi. Penelitian ini bertujuan untuk mengkaji pengaruh komposisi glass fiber non dental dan penambahan silane terhadap kekuatan geser FRC sebagai retainer ortodonsi. Subjek penelitian terdiri dari 9 kelompok perlakuan dengan 3 jenis glass fiber yang berbeda yaitu glass fiber non dental A (LT, Cina), B (CMAX, Cina) dan C (HJ, Cina). Masing-masing glass fiber diberi perlakuan yang bervariasi yaitu tanpa penambahan silane, penambahan silane 1x dan 2x. Subjek penelitian direndam dalam akuades dan disimpan pada suhu 37ºC selama 24 jam sebelum dilakukan uji kekuatan geser dengan menggunakan alat Universal Testing Machine. Hasil penelitian dianalisis variansi dua jalur dan post hoc Tukey untuk mengetahui perbedaan statistik masing-masing kelompok. Hasil penelitian menunjukkan bahwa glass fiber non dental A dengan penambahan 2x silane memiliki rerata kekuatan geser tertinggi (12,72±2,02 MPa) sedangkan glass fiber non dental B tanpa penambahan silane memiliki rerata kekuatan geser terendah (6,96±1,69 MPa). Terdapat perbedaan bermakna antara komposisi fiber maupun penambahan silane terhadap kekuatan geser FRC (p<0,05). Tidak terdapat perbedaan bermakna pada letak kegagalan FRC (p>0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa komposisi SiO2 dan Al2O3 yang tinggi pada glass fiber non dental serta penambahan silane dapat meningkatkan kekuatan geser FRC. The Effect of Non Dental Glass Fiber Composition and Silane Addition on The Shear Bond Strength of Fiber Reinforced Composite as An Orthodontic Retainer. Retainers are required to stabilize the position of the teeth to permit reorganization of periodontal tissue. FRC orthodontic retainer was developed as an alternative material aesthetic and safe for nickel allergic patients. E-glass fiber is commonly used as an orthodontic retainer. The purpose of this study was to assess the effect of non dental glass fiber composition and silanes addition on the shear bond strength of the FRC as an orthodontic retainer. This study consisted of 9 treatment groups with three different types of non dental glass fiber, namely non dental glass fiber A (LT, China), B (CMAX, China) and C (HJ, China). Each glass fiber was given a variation treatment, without silanes, one time and two times of silanes addition. All the samples were stored in distilled water at 37ºC for 24 hours and subsequently tested for shear strength by using Universal Testing Machine.The groups were submitted to two way ANOVA analysis of variance with Tukey post test to verify the statictical difference between groups. The results showed that a non dental glass fiber A with two times of silanes addition has the highest shear bond strength (12,72±2,02 MPa), meanwhile a non dental glass fiber B without silane addition has the lowest shear bond strength (6,96±1,69 MPa). There were significant differences between the composition of glass fiber and the addition of silane toward the shear bond strength of FRC (p<0,05). No significant differences in debonded locations of FRC (p>0,05). Based on the results of this study concluded that the composition of the high SiO2 and Al2O3 in the non dental glass fiber  and the silanes addition can increase the shear bond strength FRC.

Abstract

Resin akrilik merupakan bahan yang sering digunakan dalam pembuatan basis gigi tiruan. Kelemahan resin akrilik adalah mudah patah. Salah satu cara untuk mengatasi masalah tersebut adalah dengan menambahkan polyethylene (PE) atau glass fiber. Tujuan dari penelitian ini untuk mengetahui pengaruh jenis dan volumetrik fiber terhadap kekuatan transversal reparasi plat resin akrilik. Penelitian ini menggunakan dua puluh lima plat resin akrilik kuring panas berukuran 65 x 10 x 2,5 mm. Subjek dipreparasi untuk membuat jarak 3 mm dan sudut bevel 45o. Subjek dibagi menjadi 5 kelompok, masingmasing kelompok terdiri dari 5 subjek. Kelompok 1 (kontrol) tanpa penambahan fiber, kelompok II dengan penambahan 3,7% v/v PE fiber, kelompok III dengan penambahan 7,4% v/v PE fiber, kelompok IV dengan penambahan 3,7% v/v E-glass fiber, dan kelompok V dengan penambahan 7,4% v/v E-glass fiber. Seluruh plat direndam dalam air destilasi selama satu hari pada suhu 37oC. Pengujian kekuatan transversal plat resin akrilik dengan menggunakan Universal Testing Machine dan data yang didapat dianalisis menggunakan ANAVA dua jalur dengan tingkat kepercayaan 95%. Rerata kekuatan transversal (MPa) reparasi plat resin akrilik yang diperkuat fiber: 3,7% v/v PE fiber (67,77±3,34); 7,4% v/v PE fiber (80,37±8,42); 3,7% v/v E-glass fiber (96,72±5,43); 7,4% v/v E-glass fiber (109,44±4,98); sedangkan reparasi plat resin yang tidak diperkuat fiber menghasilkan kekuatan transversal 56,27±4,7 MPa. Hasil analisis menggunakanANAVA dua jalur menunjukkan variabel jenis dan volumetrik fiber memberikan pengaruh signifikan (p<0,05), sedangkan interaksi antara jenis dan volumetrik fiber tidak berpengaruh signifikan (p>0,05). Uji post hoc Tukey menunjukkan perbedaan signifikan (p<0,05) untuk seluruh kelompok perlakuan. Penambahan E-glass fiber dalam reparasi plat resinakrilik mampu meningkatkan kekuatan transversal lebih tinggi dibandingkan dengan menggunakan PE fiber. Peningkatan volumetrik fiber dapat meningkatkan kekuatan transversal reparasi plat resin akrilik. Effect Of Type And Volumetric Fiber On Transverse Strength Of Acrylic Resin Plate Repair. Acrylic resin is the most common denture base material. A disadvantage of acrylic resin is that it is easily fractured. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to find out about the effect of type and volumetric fiber on transverse strength of acrylic resin plate repaired. The experiment involved twenty five plates of heat cured acrylic with the dimensions of 65 x 10 x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. The subjects were divided into 5 groups; each group consisted of 5. Group I (control) was without fiber reinforcement, group II reinforced with 3.7% v/v PE fiber, group III reinforced with 7.4% v/v PE fiber, group IV reinforced with 3.7% v/v E-glass fiber, and group V reinforced with 7.4% v/v E-glass fiber. All plates were soaked in distilled water for one day at 37° C temperature. The plates were tested for transverse strength with Universal Testing Machine and all data obtained were analyzed with two way ANOVA at 95% confidence level. The mean of transverse strength (MPa) of the acrylic resin plate repair reinforced with fiber: 3.7% v/v PE fiber was (67.77±3.34); 7.4% v/v PE fiber (80.37±8.42); 3.7% v/v E-glass fiber (96.72±5.43); 7.4% v/v E-glass fiber (109.44±4.98); while the transverse strength of the acrylic resin plate with no fiber reinforced was 56.27±4.7 MPa. Two way ANOVA analysis shows that type and volumetric fiber had significant effect (p<0.05), while the interaction between type and volumetric fiber had no significant effect (p>0.05). Tukey post hoc test shows significant difference (p<0.05) for all groups. The addition of E-glass fibers in the acrylic resin plate repaired increased the transverse strength higher than that with PE fibers. The increase in volumetric fibers might improve the transverse strength of the acrylic resin plate repaired.

Abstract

Latest Development of Guided Tissue Regeneration and Guided Bone Regeneration Membrane as Regenerative Therapy on Periodontal Tissue. Periodontitis is a patological state which influences the integrity of periodontal system that could lead to the destruction of the periodontal tissue and end up with tooth loss. Currently, there are so many researches and efforts to regenerate periodontal tissue, not only to stop the process of the disease but also to reconstruct the periodontal tissue. Periodontal regenerative therapy aims at directing the growth of new bone, cementum and periodontal ligament on the affected teeth. Regenerative procedures consist of soft tissue graft, bone graft, roots biomodification, guided tissue regeneration and combination of the procedures, including restorative surgical procedure that is connected with oral rehabilitation with implant placement. At cellular phase, periodontal regeneration is a complex process with well-organized proliferation, distinction, and development of various type of cell to form attachment of periodontal tissue. Rationalization of the use of guided tissue regeneration as barrier membrane is to prohibit the penetration of epithelial and connective tissue migration into the defect, to maintain space, and to stabilize the clot. This research discusses: 1. Healing process on periodontal therapy including regeneration, repair or formation of new attachment. 2. Periodontal specific tissue engineering. 3. Various commercially available membrane/guided tissue regeneration in the market with its advantages and disadvantages and their characteristics. 4. Recent advancement of membrane as regenerative therapy on periodontal disease. In addition, this review is presented to give an outlook for promising regenerative therapy as a part of developing knowledge and skills to treat periodontal disease.

Abstract

Profile of Angular Cheilitis in HIV/AIDS Patients at UPIPI RSUD Dr. Soetomo Surabaya 2014. For over twenty years, human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) have become a significant public health concern, and the epidemic continues to challenge humanity. HIV related oral lesions can be used as markers of the immune status. Angular Cheilitis (AC) which is one of the seven oral manifestations which are strongly associated with HIV Infection, has been identified and internationally calibrated. The purpose of this research is to identify the Angular Cheilitis and its association with reduced Cluster of Differentiation 4 (CD4+) count in HIV/AIDS patients at Unit Perawatan Intermediet Penyakit Infeksi (UPIPI) RSUD Dr. Soetomo Surabaya. This was an Analytic observasional research with cross-sectional and total sampling method. The samples consisted of 88 HIV/AIDS patients treated in UPIPI RSUD Dr. Soetomo Surabaya from July to August 2014. The Diagnosis of Angular Cheilitis was based on clinical appearance; the oral cavities of the research subjects were examined by dentists specialized in Oral Medicine. CD4+ counts were obtained from the patient’s medical record. Eighty Eight HIV/AIDS patients were examined and there were 120 cases of oral manifestation. There were 31 cases of Angular Cheilitis (25,83%). Angular Cheilitis was found to be significantly correlated to the decrease in CD4+ cell count below 200 cells/mm3 (P< -,245). Risk Relative anaylsis concludes that HIV/AIDS patients with Candidiasis Oral 7.5 more often suffer from AC. There is a correlation between AC and OC (p<0,357). Angular Cheilitis may be used as an alternative to predict CD4+ count at field-based settings to diagnose the immunocompromised status of HIV-infected individuals.

Mini screw orthodontics is an instrument which is used in orthodontic treatment for some cases that require absolute anchorage. Available mini screws are made of nickel titanium or stainless steel alloy which in some patients may cause a reaction to the tissues. Implantation test is a test performed to determine the biocompatibility of medical devices that are directly contacted to the living tissue. Tissue response to injury after implantation affects the degree of formation of granulation tissue, foreign body reaction, and fibrosis. The aim of this study is to determine the local effect of implantation of cobalt chromium as an alternative material for mini screw orthodontic against the subcutaneous tissue of albino rabbits. The subjects of study were 20 male albino rabbits divided into two groups (treatment and negative control groups). Cobalt chromium was made in the form of discs with 10 mm in diameter and 1 mm in thickness. In the treatment group, the material was implanted in the subcutaneous tissue of the dorsum of the rabbits with an incision to form a subcutaneous pocket. The pocket base was not more than 10 mm from the initial line of incision then suturing was performed. The control group only had incision then sutured to maintain aseptic conditions. Macroscopically 24 hours after implantation, the implant area was observed related to the occurrence of oedema, haematoma, encapsulation and signs of inflammation. The evaluation on day 14 post-implantation shows the histopathologic changes observed by the infiltration of inflammatory cells types. The average of the results was analyzed using independent sample t-test. The results of the macroscopic observation shows that the treatment and control group were only seen of mild inflammatory signs included erythema. The mean and standard deviation of the amount of PMN, lymphocyte, plasma cells, macrophage, giant cell, neovascularisation, and fibrosis from cobalt chromium and control groups were (0.6 ± 0.49; 0.7 ± 0.48); (0.9 ± 0.87; 1.0 ± 0.67); (0.6 ± 0.24; 0.6 ± 0.21); (1.4 ± 0.84; 0.9 ± 0.74); (0.5 ± 0.27; 0); (0.6 ± 0.33; 0.7 ± 0.48); (0.5 ± 0.27; 0.1 ± 0.02). The results of t-test show a significant difference in giant cell (p<0.05), while the six others did not (p>0.05). The conclusion of this study is that the cobalt chromium alloy can affect the subcutaneous tissue by inducing giant cell infiltration on day 14 post-implantation as the result of foreign body reactions.

Abstract

Radiograf panoramik mencitrakan gigi-geligi rahang bawah dan atas beserta seluruh jaringan pendukungnya dalam sebuah citra tunggal, proses pemeriksaannya murah, cepat, dan mudah, serta paparan radiasi yang diterima oleh pasien relatif rendah. Di samping memiliki sejumlah keunggulan tersebut, radiograf panoramik juga memiliki kelemahan karena gambaran yang dihasilkan pada teknik radiografi ini mengalami distorsi geometris, sehingga hasil pencitraan pada radiografi panoramik cenderung tidak sesuai dengan ukuran struktur anatomi yang sesungguhnya pada pasien. Penelitian ini bertujuan untuk mengetahui perbedaan hasil pengukuran horizontal pada preparat mandibula dibandingkan dengan pengukuran horizontal pada citra radiograf panoramik, serta untuk mengetahui seberapa besar distorsi pengukuranhorizontal pada radiograf panoramik. Sampel penelitian berupa 56 buah preparat mandibula yang masing-masing diberi 23 buah metal marker. Radiograf panoramik diambil dari masing-masing sampel. Pengukuran horizontal pada sampel menggunakan sliding caliper digital, sedangkan pengukuran horizontal pada radiograf panoramik menggunakankomputer. Hasil penelitian menunjukkan bahwa terdapat perbedaan rerata yang bermakna (p<0,05) antara hasil pengukuran pada radiograf panoramik dibandingkan dengan hasil pengukuran pada preparat mandibula, kecuali pada hasil pengukuran horizontal regio gigi geligi posterior dan regio median line hingga posterior korpus mandibula. Hasil penelitian ini menunjukkan bahwa pada penempatan posisi kepala pasien yang memenuhi standar akan dihasilkan radiograf panoramik dengan distorsi geometris berupa penyempitan dimensi horizontal pada regio anterior mandibula. Pengukuran horizontal pada radiograf panoramik memiliki akurasi yang baik jika dilakukan pada regio posterior, namun cenderung tidak akurat jika dilakukan secara memanjang melintasi median line. Differences of Horizontal Measurement on Dry Mandibles and Panoramic Radiographs. Panoramic radiograph produces one single image of both maxillary and mandibular dental arches and their supporting structures. This technique is cheap, fast and easy, with relatively low radiation exposure received by patients. However, the panoramic radiograph also has some disadvantages related to its geometric distortion. The images of patient’s anatomical structureson panoramic radiograph are not equal with their actual dimension. The aim of this study is to determine the distortion of panoramic radiograph, by comparing the horizontal measurements on panoramic radiographs with those on the real object, which was the dry mandibles. The samples of this study were 56 dry mandibles with 23 metal markers on each ofthem. Panoramic radiograph was taken from each sample. Horizontal measurements on dry mandibles were done using digital sliding caliper, while horizontal measurements on panoramic radiograph were done using computer. The result of this study shows that there were significant differences (p<0.05) between horizontal measurements on panoramicradiographs compared with the measurements on dry mandibles, except in posterior dental arch and median line up toposterior region of mandible corpus. The results of this study indicate that panoramic radiograph taken on standardized patient’s head positioning procedure would produce geometric distortion that tends to be narrow on mandibular anterior region. The horizontal measurements of panoramic radiographs show good accuracy in posterior region, but tend to be inaccurate if done extended across the midline.
