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.

Background: Tooth extraction can naturally cause inflammation triggering osteoclast proliferation and alveolar bone resorption. Preservation of the tooth extraction sockets is needed for patients in order to reduce alveolar bone resorption risks. Aloe vera is known to have anthraquinones components, namely Aloin, Aloe emedin, and barbaloin, considered as anti-inflammation. Therefore, to overcome the inflammation, the role of NF-kb is very significant to decrease nuclear factor kappa b (NF-kb). As a result, inflammation risks will be decreased. Purpose: The study was aimed to determine the induction effect of combination of Aloe vera and XCB into tooth extraction sockets to reduce inflammation by reducing NF-kb expression, osteoclasts and osteoblasts. Methods: Forty-eight Cavia cobaya were divided into eight groups, each group consisted of six animals. The mandibular incisors of those Cavia cobaya were extracted and induced with either PEG, XCB, Aloe vera, or the combination of Aloe vera + XCB. Those animals were sacrificed on day 7 and day 30 after the extraction. Then immunohistochemical and histopathology examinations were conducted to observe NF-kb expression, osteoblasts and osteoclasts. Results: It was known that in group induced with the combination of Aloe vera and xenograft concelous bovine, the growth of osteoblasts was high, while NF-kb expression and osteoclasts reduced. Conclusion: It can be concluded that the induction of the combination of Aloe vera and XCB into the tooth extraction sockets can reduce NF-kb expression and osteoclast, as a result, alveolar bone resorption risks decrease, and osteoblast increase.Latar belakang: Trauma mekanis akibat pencabutan gigi asli menyebabkan keradangan. Keradangan memicu proliferasi osteoklas sehingga menyebabkan resorpsi tulang alveolararis. Pada pembuatan gigi tiruan, resorpsi tulang alveolar yang terjadi, sangat tidak diinginkan, sebab resorpsi tulang alveolar mengurangi keberhasilan pembuatan gigitiruan. Diperlukan preservasi soket pencabutan gigi asli pada penderita untuk mencegah terjadinya resorpsi tulang alveolar. Aloe vera mempunyai komponen anthraquinon yaitu aloin, Aloe emodin, barbaloin yang merupakan anti inflamasi yang dapat secara cepat menyembuhkan luka, sehingga berpotensi untuk digunakan pada preservasi soket. Didalam mengatasi keradangan peran NF-kb sangat berarti, sebab penurunan NF-kb akan mengurangi terjadinya inflamasi. tujuan: Penelitian ini bertujuan untuk menguji apakah induksi kombinasi lidah buaya dan XCB ke soket pencabutan gigi dapat mengurangi peradangan dengan mengurangi ekspresi NF - kb , osteoklas dan osteoblast. Metode: Empat puluh delapan ekor Cavia cabaya yang terdiri dari 8 kelompok, tiap kelompok 6 ekor, kelompok pengisian PEG (kontrol), kelompok pengisian XCB, kelompok pengisian aloe vera dan kelompok pengisian kombinasi aloe vera dan XCB, kelompok ini terdiri dari kelompok 7 dan 30 hari, kemudian diperiksa dengan imunohistokimia ekspresi NF-kb dan pemeriksaan histologi untuk osteoblas dan osteoklas. Hasil: Kelompok yang diisi kombinasi Alo vera dan xenograft concelous bovine pada soket pencabutan gigi, menunjukan nilai tertinggi dalam pertumbuhan osteoblas dan penurunan pada ekspresi NF-kb dan osteoklas. Simpulan: Induksi kombinasi Aloe vera dan xenograft concelous bovine pada preservasi soket pencabutan gigi dapat menurunkan ekspresi NF-kB dan osteoklas, menurunkan resiko resorpsi tulang alveolar dan meningkatkan osteoblas.

The variables observed in this research were Hsp60, CD-8 and IFN-γ. Measurements were conducted by using immunohistochemical methods on periapical tissue. Results: The mean of Hsp60, CD-8 and IFN-γ in granuloma group was significantly higher than those in non granuloma group (p<0.05). The positive role of IFN-γ on the incidence of granulomas appeared to be more prominent. Conclusion: The study suggested that in immunopathobiogenesis of periapical granuloma in dental caries, Hsp60, CD-8 and IFN-γ played important roles, but the role of IFN-γ was found to be more prominent.Latar belakang: Angka kejadian gigi karies dengan granuloma periapikal di Indonesia cukup tinggi, Namun mekanisme terbentuknya granuloma periapikal pada gigi karies yang disebabkan oleh infeksi bakteri secara imunopatobiogenesis belum dapat dijelaskan secara tuntas. Adanya penjelasan ini diperlukan agar dapat digunakan sebagai dasar pengembangan diagnosis, langkah preventif dan terapinya. Tujuan: Penelitian ini bertujuan untuk mengetahui peran Hsp60, CD-8 dan IFN-γ dalam immunopatobiogenesis dari granuloma periapikal karies gigi. Metode: Penelitian ini merupakan penelitian observasional analitik dengan pendekatan cross sectional. Sampel dari penelitian ini adalah 36 gigi pasien dengan karies, yang terdiri dari 18 karies gigi dengan granuloma periapikal dan 18 karies gigi tanpa granuloma periapikal. Variabel yang diamati adalah Hsp60, CD-8 dan IFN-γ. Pengukuran dilakukan dengan menggunakan metode imunohistokimia pada jaringan periapikal. Hasil: Rerata Hsp60, CD-8 dan IFN-γ pada kelompok granuloma secara signifikan lebih tinggi dibanding kelompok non granuloma (p <0,05). Peran positif dari IFN-γ terhadap kejadian granuloma tampaknya lebih menonjol. Simpulan: Studi ini menunjukkan bahwa dalam imunopatobiogenesis dari granuloma periapikal karies gigi, Hsp60, CD-8 dan IFN-γ memainkan peran penting, tetapi peran IFN-γ ditemukan lebih menonjol.

Background: The concept of stem cell therapy is one of the new hope as a medical therapy on salivary gland defect. However, the lack of viability of the transplanted stem cells survival rate led to the decrease of effectiveness of stem cell therapy. The underlying assumption in the decrease of viability and function of stem cells is an increase of apoptosis incidence. It suggests that the microenvironment in the area of damaged tissues is not conducive to support stem cell viability. One of the microenvironment is the hypoxia condition. Several scientific journals revealed that the administration of hypoxic cell culture can result in stress cells but on the other hand the stress condition of the cells also stimulates heat shock protein 27 (HSP 27) as antiapoptosis through inhibition of caspase 9. Purpose: The purpose of this study was to examine the role of heat shock protein 27 as inhibitor apoptosis in hypoxic conditions of bone marrow stem cell culture. Methods: Stem cell culture was performed in hypoxic conditions (O2 1%) and measured the resistance to apoptosis through HSP 27 and caspase 9 expression of bone marrow mesenchymal stem cells by using immunoflorecence and real time PCR. Results: The result of study showed that preconditioning hypoxia could inhibit apoptosis through increasing HSP 27 and decreasing level of caspase 9. Conclusion: The study suggested that hypoxic precondition could reduce apoptosis by increasing amount of heat shock protein 27 and decreasing caspase 9.Latar belakang: Konsep terapi stem cell merupakan salah satu harapan baru sebagai terapi medis kelainan kelenjar ludah. Namun, rendahnya viabilitas stem cell yang ditransplantasikan menyebabkan penurunan efektivitas terapi. Asumsi yang mendasari rendahnya viabilitas dan fungsi stem cell adalah tingginya kejadian apoptosis. Hal ini menunjukkan bahwa lingkungan mikro di daerah jaringan yang rusak tidak kondusif untuk mendukung viabilitas stem cell. Salah satu lingkungan mikro adalah kondisi hipoksia. Beberapa jurnal ilmiah mengungkapkan bahwa kondisi hipoksia pada kultur sel dapat menyebabkan sel-sel stres, namun di sisi lain kondisi stres sel juga merangsang heat shock protein 27 (HSP 27) sebagai antiapoptosis dengan menghambat ekspresi caspase 9. Tujuan: Tujuan penelitian ini adalah untuk meneliti peran protein heat shock 27 sebagai inhibitor apoptosis dalam kondisi hipoksia kultur stem cell sumsum tulang. Metode: Kultur stem sel dilakukan dalam kondisi hipoksia (O2 1%) dan mengukur resistensi terhadap apoptosis melalui ekspresi HSP 27 dan caspase 9 stem cell mesenchymal sumsum tulang dengan menggunakan immunoflorecence dan PCR real time. Hasil: Hasil penelitian menunjukkan bahwa prakondisi hipoksia dapat menghambat apoptosis melalui peningkatan HSP 27 dan penurunan tingkat Caspase 9. Simpulan: Studi ini menunjukkan bahwa prakondisi hipoksia dapat mengurangi apoptosis dengan meningkatkan jumlah protein heat shock 27 dan penurunan caspase 9.
