Abstract

Non precious alloys were used widely in dentistry, because cost was relatively lower than noble alloys (precious alloy). This study aims to evaluate the microhardness NiCr alloys were frequently used in the construction of crown and bridges prosthodontics and metal frame dentures with different methods. Casting methods used were: 1) induction / argon, the argon electromagnetic induction with controlled atmospheric pressure, 2) induction / vacuum, the electromagnetic induction in a vacuum environment, 3) induction /air, electromagnetic induction air was not controlled by atmospheric pressure and 4) flame / air from combustion of gas / oxygen in centrifugal castings machine was not controlled by atmospheric pressure. The three of alloys used were Ni-Cr-Mo-Ti: Ni-Cr-Mo-Be and Ni-Cr-Mo-Nb. The sample size was 60, divided into 12 groups (each group consisted of 5 samples). Cylindrical samples with a length of 15 mm and a diameter of 1.6 mm. After casting, the samples were embedded in resin and polished for Vickers microhardness measurement in a Shimadzu HMV-2 (1000 g with duration of 10 seconds). The data obtained were in the form of indentations (indentation) on the surface of the sample. The data was subjected to two-way ANOVA and Tukeys multiple comparison test ( = 0.05). The two way ANOVA suggested a non significant effect of the interaction alloys versus casting (p=0.10). A significant effect of alloy (p<0.0001)and casting methods (p<0,0001) was detected. The hardness value of Ni-Cr-Mo-Ti (421 ± 7.8) was higher (p <0.05) than the Ni-Cr-Mo-Nb (414 ± 7.6). The hardness value of the casting method of induction / argon and induction/ vacuum was similar (p> 0.05), and lower than the induction / air and flame / air (p <0.05). The lowest hardness value was Ni-Cr-Mo-Be (358 ± 10.7). The hardness value in the condition induction/ air and flame /air was similar (p> 0.05). The microhardness of the alloys was influenced by their composition and casting method. The microhardness of NiCr alloy hardness was higher when they were cast with induction/air and flame/air methods

Abstract

Primary hypertension is a causing factor of cardiovascular disease mortality. Patient with primary hypertension having high grade hypertension will cause various dangerous diseases if it is not performed further countermeasures. Consequently, it is necessary to prevent the increase of grade hypertension or blood pressure by analyzing grade hypertension risk factor. This study was quantitative research with cross sectional design method. The samples in this study were 346 respondents taken by consecutive sampling. Partial Least Square (PLS) with SmartPLS (v. 3.2.7) application software was used as to analyze the data. Results shows that there is a physical activity effect on grade hypertension, with the value of path coefficient by -0.564 of t statistic 16.48 (t statistic > t table significance by 1.96). Based on the result of the study, there is a topography effect on grade hypertension, with the value of path coefficient by 0.412 of t statistic 8.690 (t statistic > t table significance by 1.96). Physical activity affects grade hypertension. The better the physical activity, the better the way to prevent a blood pressure increase mainly systolic blood pressure. The high topography can lead to increase grade hypertension in the primary hypertension patient, therefore, lifestyle and topographic effect should also be considered for people with primary hypertension mainly for non-native people who have not experienced acclimatization. Keywords: Primary hypertension, Topography, Physical activity, Grade hypertension

Abstract

Background: Restoration of NiCr may undergo corrosion process in artificial saliva. Corrosion product is soluble Ni substances in salivary electrolytes. Ni2+ may freely enter the cells through passive transport DMT-1. Ni2+ in the cell causes initiation of the ROS formation,which subsequently can conduct the redoxs reactions leading to DNA damage. The damage DNA affects the genetic expression, especially bcl-2, and even triggers apoptosis. Purpose: The aim of this study was to reveal the mechanism of Ni toxicity as a corrosion product of NiCr restoration on gingival fibroblasts through expression analysis of Bcl-2. Methods: Cells with a density of 105 planted on each coverslip in 72 wells to the treatment group and 24 wells to the control group (24 hours incubation). In the treatment groups, each well exposed with 20 μL artificial saliva containing Ni concentration results immerse each restoration, whereas the control group was exposed to 20 μL artificial saliva (incubation 1, 3, and 7 days). The data collected were subsequently analyzed using two-ways ANOVA, followed by one-way ANOVA. Comparing between experimental groups after one-way ANOVA was conducted using Fisher’s LSD. Whereas, the calculation and documentation of Bcl-2 expression was performed camera of Olympus Microscope BX-50 Japan. Results: Statistical analysis of two-ways ANOVA showed the presence of interaction between the increasing Ni concentration and exposure duration on the expression of Bcl-2 gingival fibroblasts (p=0.021<a=0.05). Conclusion: It can be concluded that the higher concentration of Ni exposed to gingival fibroblasts, and the longer incubation time will decreased Bcl-2 expression.Latar belakang: Restorasi NiCr dapat mengalami proses korosi di dalam saliva artificial. Produk korosi yang dihasilkan adalah substansi Ni yang terlarut di dalam elektrolit saliva. Ni2+ bebas dapat memasuki sel (fibroblas gingiva) melalui transport pasif DMT-1. Ni2+ di dalam sel menginisiasi pembentukan ROS, yang selanjutnya dapat menjalankan reaksi redoks dan dapat menimbulkan kerusakan DNA. DNA yang rusak mempengaruhi ekspresi genetik, terutama Bcl-2 dan bahkan dapat memicu apoptosis. Tujuan: Tujuan penelitian ini adalah untuk mengungkap mekanisme toksisitas Ni sebagai suatu produk korosi restorasi NiCr pada fibroblas gingiva melalui analisis ekspresi Bcl-2. Metode: Sel dengan kepadatan 105 ditanam pada tiap-tiap coverslip di dalam 72 well untuk kelompok perlakuan dan ditanam pada tiap-tiap coverslip di dalam 24 well untuk kelompok kontrol (inkubasi selama 24 jam). Pada kelompok perlakuan, masing-masing well dipapar dengan 20 μL saliva artificial yang mengandung konsentrasi Ni hasil perendaman tiap-tiap restorasi, sedangkan pada kelompok kontrol dipapar 20 μL saliva artificial (inkubasi 1,3 dan 7 hari). Data yang terkumpul selanjutnya dianalisis menggunakan ANOVA dua arah dan ANOVA satu arah. Perbandingan antar kelompok eksperimental setelah analisis ANOVA satu arah menggunakan uji Fisher’s LSD. Penghitungan jumlah sel yang mengekspresikan Bcl-2, kemudian dilanjutkan dengan dokumentasi dengan menggunakan kamera Olympus Microscope BX-50 Japan. Hasil: Analisis statistik ANOVA dua arah menunjukkan adanya interaksi antara peningkatan konsentrasi Ni dan lama paparan terhadap ekspresi Bcl-2 fibroblas gingiva > (p = 0,021 < á = 0,05). Kesimpulan: Dapat disimpulkan bahwa semakin tinggi konsentrasi paparan Ni pada fibroblas gingiva dan semakin lama masa inkubasi, maka akan menurunkan ekspresi Bcl-2.

Abstract

Background: The construction of overdenture is often applied because endodontic treatment usualy give very promising results and patient has high motivation to maintain their natural teeth. Overdenture is a removable partial or complete denture that covers and rests on one or more remaining natural teeth, roots and/or dental implants. The presence of retained teeth can maximize retention, stabilization and prevent trauma to the oral mucosa. Meanwhile, the presence of root in the bone can delay resorption of the alveolar process. The role of proprioceptor in the periodontal ligament abutment teeth remains effective. Thus, it can be said the overdenture treatment is a preventive prosthodontic treatment. Purpose: The purpose of this case report was to present a case of maxillary and mandibullary anterior teeth with periodontal disease, through endodontic and prosthodontic treatments for recovering its function of phonetic and aesthetic. Case: The 25 years old female with periodontal problems (protrusive, wiggly °1–°2 and along with gingival retraction) on 12, 11, 21, 22 and 32, 31, 41, 42. The patient felt bad about his performance and affect his self confidence. The patient visited tthe dental hospital to restore her teeth and recovering aesthetic and phonetic functions. Case management: The overdenture inserted immediately after one visit endodontic treatment and cutting off the clinical crown of the teeth. The adaptation of the denture is needed by relining using self cured acrylic resin. The patient was quite satisfied with the treatment. Conclusion: In conclusion, the maxillary and mandibullary anterior teeth with periodontal problem could be managed through conservative and prosthotontic approach of treatment to recover of its performance and function.Latar belakang: Konstruksi overdenture sering diaplikasikan pada pasien, karena perawatan endodontik memberikan hasil perawatan yang sangat menjanjikan dan pasien memiliki motivasi tinggi untuk mempertahankan gigi asli mereka. Overdenture adalah gigi tiruan lepasan sebagian atau lengkap yang bertumpu pada satu atau lebih gigi asli yang tersisa, akar dan/atau implan gigi. Gigi asli yang tersisa di dalam mulut dapat memaksimalkan retensi, stabilisasi dan mencegah trauma pada mukosa oral. Selain itu, dipertahankannya sisa akar gigi dapat menghambat resorpsi tulang alveolar serta peran proprioseptor ligamen periodontal tetap efektif. Dengan demikian, dapat dikatakan bahwa perawatan overdenture adalah perawatan prostodontik pencegahan. Tujuan: Tujuan dari laporan kasus ini adalah untuk mempresentasikan kasus gigi-gigi anterior rahang atas dan rahang bawah dengan penyakit periodontal melalui perawatan endodontik dan prostodontik untuk memulihkan fungsi fonetik dan estetik. Kasus: Wanita usia 22 tahun dengan masalah periodontal (protrusi, goyang °1–°2 dan disertai dengan retraksi gingival) pada 12, 11, 21, 22 dan 32, 31, 41, 42. Pasien datang ke rumah sakit gigi dan mulut ingin memperbaiki giginya untuk mengembalikan fungsi estetik dan fonetik. Pasien merasa kurang percaya diri terhadap penampilannya. Tatalaksana kasus: Overdenture dipasang segera setelah perawatan one visit endodontik yang diikuti dengan pemotongan mahkota klinis. Relining dengan resin akrilik diperlukan untuk menyesuaikan gigi tiruan terhadap jaringan pendukungnya. Pasien cukup puas dengan perawatan ini. Kesimpulan: Disimpulkan bahwa, gigi-gigi anterior rahang atas dan rahang bawah dengan masalah periodontal dapat diperbaiki melalui pendekatan perawatan konservasi dan prostodonsi untuk memperbaiki penampilan dan fungsi.
