Abstract

Background: Dental caries is a bacterial infection which causes destruction of the hard tissues of the tooth. Exposure of the dentin to the oral environment as a result of caries inevitably results in a cellular response in the pulp. The major histocompatibility complex (MHC) is a group of genes that code for cell-surface histocompatibility antigens. Cells expressing class II MHC molecules participate in the initial recognition and the processing of antigenic substances to serve as antigen-presenting cells. Purpose: The aim of the study was to elucidate the alteration in the distribution of class II MHC antigen-expressing cells in human dental pulp as carious lesions progressed toward the pulp. Methods: Fifteen third molars with caries at the occlusal site at various stages of decay and 5 intact third molars were extracted and used in this study. Before decalcifying with 10% EDTA solution (pH 7.4), all the samples were observed by micro-computed tomography to confirm the lesion condition three-dimensionally. The specimens were then processed for cryosection and immunohistochemistry using an anti-MHC class II monoclonal antibody. Results: Class II MHC antigen-expressing cells were found both in normal and carious specimens. In normal tooth, the class II MHC-immunopositive cells were observed mainly at the periphery of the pulp tissue. In teeth with caries, class II MHC-immunopositive cells were located predominantly subjacent to the carious lesions. As the caries progressed, the number of class II MHC antigen-expressing cells was increased. Conclusion: The depth of carious lesions affects the distribution of class II MHC antigen-expressing cells in the dental pulp.Latar belakang: Karies merupakan penyakit infeksi bakteri yang mengakibatkan destruksi jaringan keras gigi. Dentin yang terbuka akibat karies akan menginduksi respon imun seluler pada pulpa. Kompleks histokompatibilitas utama (MHC) merupakan sekumpulan gen yang mengkode histokompatibilitas antigen-antigen permukaan sel. Sel-sel yang mengekspresikan molekul-molekul ini berpartisipasi dalam pengenalan awal substansi-substansi antigenik untuk selanjutnya diproses dan dipresentasikan pada permukaan sel. Tujuan: Penelitian ini bertujuan untuk mengetahui perubahan distribusi sel-sel yang mengekspresikan molekul MHC kelas II pada pulpa gigi manusia dengan meningkatnya keparahan karies. Metode: Penelitian ini menggunakan 15 gigi molar ketiga yang mengalami karies pada permukaan oklusal dengan berbagai tingkat kedalaman dan 5 gigi molar ketiga normal (tidak mengalami karies). Sebelum didekalsifikasi dengan larutan EDTA 10% (pH 7,4), seluruh sampel diamati dengan menggunakan micro-computed tomography untuk mengetahui kedalaman lesi karies secara tiga dimensi. Spesimen kemudian diproses untuk dilakukan cryosection dan dilakukan immunohistokimia dengan menggunakan monoklonal antibodi anti MHC kelas II. Hasil: Ekspresi MHC kelas II oleh sel-sel pada ruang pulpa dijumpai disemua spesimen baik pada kondisi normal maupun karies. Pada gigi normal, sel-sel yang mengekspresikan MHC kelas II terletak terutama pada tepi pulpa. Pada gigi-geligi yang mengalami karies, agregasi sel-sel yang mengekspresikan MHC kelas II terutama terletak di bawah lesi karies. Semakin dalam lesi karies, jumlah sel-sel yang mengekspresikan MHC kelas II semakin meningkat. Kesimpulan: Kedalaman lesi karies berpengaruh terhadap distribusi sel-sel yang mengekspresikan MHC kelas II pada pulpa.

Abstract

Background: Self-adhering flowable composite is a combination of composite resin and adhesive material. Its application needs scrubbing process on the dentin surface, but sometimes it is difficult to determine the pressure and duration of scrubbing. Purpose: This study was aimed to analyze the effect of scrubbing pressure and duration on shear bond strength of self-adhering flowable composite to dentin surface Methods: Fifty four mandibulary third molar were cut to get the dentin surface and divided into nine groups (n = 6). Dentin surface was scrubbed with 1, 2, and 3 grams of scrubbing pressure, each for 15, 20, and 25 seconds respectively. surface was scrubbed with 1, 2, and 3 grams of scrubbing pressure, each for 15, 20, and 25 seconds respectively. Composite resin was applied incrementally and polymerized for 20 seconds. All specimens were immersed in saline solution at 37º C for 24 hours. Shear bond strength was tested for all specimens by using Universal Testing Machine (Shimadzu AG-5000E, Japan) at a crosshead speed of 1 mm/minute and analyzed by ANOVA and Post Hoc Test Bonferonni. The interface between self-adhering flowable interface between self-adhering flowable composite and dentin was observed with a Scanning Electron Microscope (JEOL JSM 6510LA). Results: The highest shear bond strength was obtained by 3 grams scrubbing pressure for 25 seconds or equal to applying the brush applicator in 0º relative to dentin surface. Conclusion: Increasing the scrubbing pressure and duration will increase the shear bond strength of self adhering flowable composite resin to dentinal surface. The highest shear bond strength was obtained when the applicator in 0º relative to dentin surface. Latar belakang: Self-adhering flowable composite merupakan gabungan resin komposit dengan material adhesif yang dalam penggunaannya memerlukan teknik scrubbing pada permukaan dentin, namun sulit untuk menentukan besar tekanan yang tepat saat scrubbing. Tujuan: Tujuan dari penelitian ini adalah untuk menganalisa pengaruh tekanan dan lama scrubbing saat aplikasi selfadhering flowable composite terhadap shear bond strength pada permukaan dentin. Metode: 54 gigi molar-3 rahang bawah dipotong sampai permukaan dentin dan dibagi atas 9 kelompok (n = 6). Scrubbing pada permukaan dentin dilakukan dengan besar tekanan 1, 2, dan Scrubbing pada permukaan dentin dilakukan dengan besar tekanan 1, 2, dan 3 gram, masing-masing selama 15, 20, dan 25 detik. Resin komposit diaplikasikan secara inkremental dan dipolimerisasi dengan sinar selama 20 detik. Spesimen direndam dalam larutan salin dan disimpan dalam inkubator pada suhu 37º C selama 24 jam. Shear bond strength diuji menggunakan Universal Testing Machine. Analisa data melalui uji ANOVA diikuti Post Hoc Test Bonferonni. Antarmuka self-adhering flowable composite resin dan dentin diamati melalui Scanning Electron Microscope (SEM). Hasil: Shear bond strength tertinggi antara self-adhering flowable composite resin dan dentin diperoleh pada tekanan scrubbing 3 gram selama 25 detik atau kuas membentuk sudut 0º dengan permukaan dentin. Kesimpulan: Semakin besar tekanan dan lama waktu scrubbing akan meningkatkan shear bond strength material self-adhering flowable composite resin terhadap permukaan dentin. Kekuatan paling tinggi diperoleh bila kuas aplikator membentuk sudut 0º dengan permukaan dentin selama proses scrubbing.

Abstract

Background: It has been well documented that several diseases or conditions and their related medications could be the risk factors for several ailments found in the oral cavity. Increased usage of medication in elderly could have impact on quality of saliva that affects oral health, eventually cause deterioration in quality of life. Purpose: examine the salivary pH, buffering capacity, stimulated- and unstimulated salivary flow rate profile in elderly using medications. Methods: Seventy-six elderly were consented and agreed to participate in this study. Interview and medical record analysis were performed to get data about their health status, chronic use of medications and complaints related to xerostomia. Collection of unstimulated and stimulated saliva samples were completed in parallel with measurement of salivary pH and buffering capacity. Results: The mean salivary pH was moderately acidic while having low salivary buffering capacity. The mean unstimulated salivary flow rate (USSFR) was 0.24 ± 1.8ml/min and 41of subjects (53%) were classified hyposalivation, while the stimulated salivary flow rate (SSFR) was 0.86 ± 0.49ml/min and 31 (40%) classified hyposalivation. Number of drugs-induced xerostomia intake significantly correlated with the reduction in the USSFR of subjects (p<0.0001), however it was not the case with salivary pH and buffering capacity (p>0.05). It also showed correlation with complaints related to xerostomia. The mean USSFR did not correlate with xerostomia complaints. Conclusion: Medications intake influenced salivary profile and had more effect in changes in xerostomia complaints and salivary quantity than to salivary pH and buffering capacity in Indonesian elderly population.Latar belakang: Telah lama diketahui bahwa beberapa penyakit atau kondisi sistemik dan medikasinya dapat menjadi faktor resiko terjadinya beberapa kelainan dalam rongga mulut. Meningkatnya penggunaan medikasi sistemik pada lansia dapat mempengaruhi kualitas saliva sehingga berpengaruh pada kesehatan mulut yang akhirnya menyebabkan menurunnya kualitas hidup. Tujuan: Mengetahui profil pH saliva, kapasitas dapar, laju aliran saliva terstimulasi (LAST) dan tanpa stimulasi (LASTS) pada lansia yang mendapatkan medikasi sistemik. Metode: Tujuh puluh enam lansia telah menandatangani inform consent dan setuju untuk berpartisipasi. Wawancara dan analsis rekam medis dilakukan untuk mendapatkan data tentang status kesehatan, penggunaan medikasi sistemik jangka panjang dan keluhan xerostomia. Pengumpulan saliva tanpa stimulasi dan terstimulasi dilakukan bersama-sama dengan pengukuran pH dan kapasitas dapar. Hasil: pH saliva subyek adalah berada dalam kelompok asam sedang dengan kapasitas dapar yang rendah. Rerata LASTS adalah 0,24 ± 1,8ml/menit dan 41 subyek (53%) mengalami hiposalivasi, sementara LAST adalah 0,86 ± 0,49ml/menit dan 31 subyek (40%) mengalami hiposalivasi. Jumlah medikasi yang dapat menginduksi xerostomia secara bermakna berhubungan dengan penurunan LASTS (p < 0,0001), namun tidak demikian dengan pH dan kapasitas dapar (p>0,05). Medikasi sistemik juga berhubungan dengan keluhan yang terkait xerostomia. Rerata LASTS tidak berhubungan dengan keluhan xerostomia. Kesimpulan: Medikasi sistemik pada populasi lansia Indonesia mempengaruhi profil saliva dan mempunyai pengaruh yang lebih besar pada keluhan xerostomia dan kuantitas saliva dibandingkan pH dan kapasitas dapar.

Abstract

Background: Ossifying fibroma is a variant of fibrous dysplasia and catagorized as osteofibrosis lesion. It commonly affects long bones but occasionally involves jaws. Mandible affected more common than maxilla. The treatment of ossifying fibroma include excision and resection. Excision of lesion and resection of maxilla could cause facial defect which cannot be reconstructed with bone graft. Purpose: The aim of this case report is to report the potential use of polypropylene mesh in facial reconstruction after hemimaxillectomy in patients diagnosed with ossifying fibroma of the maxilla. Case: A 17-years-old female patient came to Oral and Maxillofacial Surgery clinic, Dental Hospital, Faculty of Dentistry, Airlangga University, with chief complaint of swelling in the upper left cheek of 2 years duration which was not related to any history of toothache. Patient also complained of the itchiness and pain on the swelling area occasionally as well as salty discharge from the mass. The FNA was done and the citology result indicated a benign mesenchimal tumor. Incisonal biopsy was subsequently performed and the histopathology report confirmed the diagnosis of cementifying fibroma. Case management: Left hemimaxillectomy was done, and post surgical defect in the facial and buccal aspect was immediately reconstructed using three layers of polypropylene mesh. On follow-up, eleven months post-operatively, the patient was well and there was no facial deformity or asymmetry. Conclusion: Polypropylene mesh is a potential material for facial reconstruction as it can reduce the risk of facial deformity after hemimaxillectomy of patients with tumor of the maxilla.Latar belakang: Ossifying fibroma merupakan varian dari fibrous dysplasia dan termasuk di dalam kategori lesi osteofibrosis. Umumnya mengenai tulang panjang tetapi dapat juga mengenai rahang dan lebih banyak menyerang tulang mandibula dibanding maksila. Perawatan ossifying fibroma dilakukan dengan eksisi atau reseksi. Perawatan eksisi atau reseksi tulang maksila dapat mengakibatkan deformitas wajah yang tidak dapat direkontruksi dengan bone graft. Tujuan: Laporan kasus ini bertujuan untuk melaporkan penggunaan polipropylene mesh pada rekonstruksi wajah setelah hemimaxillectomy pada pasien dengan diagnose ossifying fibroma pada maksila. Kasus: Penderita wanita berusia 17 tahun datang ke Klinik Bedah Mulut dan Maksilofasial, Rumah Sakit Gigi dan Mulut Fakultas Kedokteran Gigi Universitas Airlangga, dengan keluhan utama pembengkakan pada pipi kiri atas yang muncul sejak 2 tahun yang lalu tanpa ada riwayat keluhan sakit gigi. Penderita mengeluh gatal, kadang sakit dan keluarnya cairan asin pada daerah benjolan. Hasil FNA dan test sitologi menunjukkan gambaran tumor jinak mesensimal. Pemeriksaan dengan biopsi dan histopatologi mengkonfirmasi diagnosa cementifying fibroma. Tatalaksana kasus: Dilakukan hemimaksilektomy pada sebelah kiri, dan defek pasca pembedahan pada sisi fasial dan bukal segera direkontruksi dengan pemasangan polipropylene mesh 3 lapis. Sebelas bulan setelah operasi kondisi pasien baik dan tidak ada deformitas atau asimetri wajah. Kesimpulan: Polypropylene mesh merupakan bahan yang potensial untuk rekonstruksi wajah karena dapat mengurangi terjadinya deformitas wajah setelah hemimaxillectomy pada pasien dengan tumor maksila.

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:

Background: The natural biopolymer chitosan (Ch) is currently regarded as a candidate for bone tissue engineering. However, Ch is poor for cell adhesion and low bone formation ability. In order to enhance cell adhesion and bone formation ability, combination of Ch with carbonate apatite (CA) was developed. Purpose: The aim of this study was to make carbonate apatite-chitosan scaffolds (CAChSs) and evaluate its osteoconductivity in terms of cell proliferation. Methods: Chitosan scaffolds (ChSs) were made by the following procedure. Twenty-five, 50, 100, 200 and 400 mg Ch was dissolved into 5 ml of 2% acetic acid (CH3COOH), shaked for 15 min and neutralized with 15 ml of 0.1 M sodium hydroxide (NaOH) solution. After centrifugation, Ch gel was packed into the molds then frozen at -80°C for 2h and dried in a freeze dry machine for 24h. The sponges were subjected to UV radiation for 2h. To make CA-ChSs, 200 mg Ch was selected. After neutralization, 50 mg of 0.06 M CA were added into the 200 mg Ch gel. The structure of CA-ChSs was observed by scanning electron microscope (SEM). Mouse osteoblast-like cell (MC3T3-E1) proliferation in these scaffolds was investigated at 1, 7, 14 and 21 days. Results: Three dimensional porous structures of CA-ChSs were clearly observed by SEM. Proliferated cell numbers in CA-ChSs was significantly higher than those in ChSs (control) at each stage (p<0.05). Conclusion: It can be concluded that newly developed CA-ChSs had three-dimensional interconnected porous structure, good handling property and supporting ability of proliferation of osteoblasts. It is suggested that newly developed CA-ChSs could be considered as a scaffolds material for bone tissue enginearing.Latar belakang: Kitosan yang merupakan biopolimer alami dianggap sebagai salah satu kandidat untuk rekayasa jaringan tulang. Namun, kitosan memiliki kelemahan terhadap adhesi sel dan kurang mampu membentuk tulang yang cukup. Untuk meningkatkan adhesi sel dan kemampuan pembentukan tulang, telah dikembangkan suatu scaffolds yang menggabungkan kitosan dengan carbonate apatite (CA). Tujuan: Penelitian ini bertujuan untuk membuat carbonate apatite-chitosan scaffolds (CA-ChSs) serta mengevaluasi osteokonduktivitas CA-ChSs dari sudut pandang proliferasi sel. Metode: Chitosan scaffolds (ChSs) dibuat dengan prosedur berikut ini. Dua puluh lima, 50, 100, 200 dan 400 mg bubuk kitosan dilarutkan dalam 5 ml asam asetat (CH3COOH) 2%, dikocok selama 15 menit dan dinetralkan dengan 15 ml 0,1 M larutan sodium hidroksia (NaOH). Setelah sentrifugasi, gel kitosan dikemas ke dalam cetakan teflon kemudian dibekukan pada suhu -80°C selama 2 jam dan dikeringkan dalam mesin beku kering pada suhu -54°C selama 24 jam. Selanjutnya dilakukan radiasi ultraviolet pada ChSs selama 2 jam. Untuk membuat CA-ChSs, dipilih ChSs yang berisi 200 mg bubuk kitosan. Setelah dinetralisir, 50 mg dari 0.06 M CA ditambahkan ke dalam kitosan gel yang berisi 200 mg bubuk kitosan. Struktur CA-ChSs diamati dengan scanning electron microscope (SEM). Proliferasi mouse osteoblast-like cell (MC3T3-E1) dalam ChSs dan CA-ChSs dievaluasi pada hari ke-1, 7 dan 14. Hasil: CA-ChSs dengan struktur tiga dimensi yang berpori dapat diamati dengan jelas menggunakan SEM. Jumlah pertumbuhan dan perkembangan sel pada CA-ChSs secara signifikan lebih banyak dibandingkan pada ChSs (kontrol) pada setiap tahap pengamatan di hari ke-1, 7, 14 dan 21 (p<0.05). Kesimpulan: Dapat disimpulkan bahwa CA-ChSs mempunyai struktur tiga dimensi dengan pori-pori yang saling berhubungan satu sama lain dan dapat meningkatkan proliferasi osteoblast. Hal ini menunjukkan bahwa CA-ChSs adalah kandidat untuk rekayasa jaringan tulang.
