"lingkungan kondusif untuk proses penyembuhan. Biological sealing dapat diperoleh melalui sifat bioaktivitas suatu material, salah satunya kemampuan biomineralisasi material, yaitu kemampuan material dalam membentuk apatite like layer pada permukaan ketika berkontak dengan cairan fisiologis. Karakteristik tersebut dapat diperoleh dari material bioaktif, seperti kalsium silikat. Siler berbasis kalsium silikat pre- mixed saat ini telah banyak berkembang, di antaranya adalah Ceraseal® (Metabiomed, Korea) dan AH Plus® Bioceramic (Dentsply, USA). Komposisi masing-masing siler yang bervariasi menghasilkan perbedaan karakteristik, salah satunya kemampuan biomineralisasi. Tujuan: Menganalisis potensi biomineralisasi antara siler berbasis kalsium silikat pada dentin saluran akar dengan perendaman phosphate buffered saline (PBS). Metode: Siler berbasis kalsium silikat Ceraseal® dan AH Plus® Bioceramic diaplikasikan ke dalam dentin saluran akar gigi premolar yang telah dilakukan prosedur preparasi saluran akar, dan dilanjutkan dengan perendaman dalam PBS selama 14 hari. Analisis biomineralisasi dilakukan dengan menganalisis pembentukan lapisan apatit setelah 14 hari perendaman melalui penghitungan ketebalan deposit lapisan apatit menggunaan Scanning Electron Microscope (SEM), serta peningkatan pH larutan yang dihitung pada waktu observasi hari-ke 0, 7 dan 14 menggunakan pH-meter. Hasil: Terdapat perbedaan deposisi apatit pada interfacial layer antara Ceraseal® dan AH Plus® Bioceramic dalam waktu observasi 14 hari. Terdapat perbedaan bermakna antara nilai pH Ceraseal® dan AH Plus® Bioceramic pada waktu observasi 7 dan 14 hari.

Background: Endodontic treatment currently refers to the concept of biological sealing to form an environment conducive to the healing process. Biological sealing can be obtained through the bioactivity properties of a material, one of which is its biomineralization ability to form an apatite-like layer on the surface when in contact with physiological fluids. This characteristic is present in bioactive materials like calcium silicate. There are currently many developed pre-mixed calcium silicate based sealers, including Ceraseal® (Metabiomed, Korea) and AH Plus® Bioceramic (Dentsply, USA). The variation in their composition results in different characteristics, including biomineralization ability. Objective: To analyze the biomineralization potential of calcium silicate-based sealers on root canal dentine by phosphate-buffered saline (PBS) immersion. Methods Calcium silicate based sealer Ceraseal® and AH Plus® Bioceramic were applied to the root canal dentin of premolar teeth that had undergone root canal preparation procedures. The samples were then immersed in PBS for 14 days. Biomineralization analysis was performed by measuring the apatite layer thickness formed after 14 days of immersion using a Scanning Electron Microscope (SEM). Additionally, the pH of the solution was measured at observation times of 0,7 and 14 days using a digital pH-meter. Results: There was a significant differences in in apatite deposition at the interfacial layer between Ceraseal® and AH Plus® Bioceramic during 14 days of observation. Furthermore, there was a significant difference in pH values between Ceraseal® and AH Plus® Bioceramic at 7 and 14 days of observation."

Sampel diinkubasi selama tujuh hari pada suhu 37oC, kemudian dipotong pada area sepertiga apikal dan medial. Nilai push-out bond strength dan failure mode dianalisis. Hasil: AH Plus® Bioceramic memiliki perbedaan nilai push-out bond strength dan failure mode yang signifikan dibanding AH Plus® dan Ceraseal. Ceraseal dan AH Plus® tidak memiliki perbedaan nilai secara signifikan. Analisis gambaran failure mode oleh dua orang observer menunjukkan reliabilitas data yang tinggi. AH Plus® Bioceramic memiliki dominasi kegagalan campuran, sedangkan Ceraseal dan AH Plus® memiliki persentasi kegagalan campuran dan kohesif yang seimbang. Kesimpulan: Seluruh kelompok siler menunjukkan kemampuan adhesi yang baik terhadap permukaan dentin, meskipun nilai push-out bond strength siler AH Plus® Bioceramic paling rendah diantara seluruh kelompok.

Background: The adhesion of sealers to dentin is important for successful endodontic treatment. As the gold standard, epoxy resin sealers have superior adhesion, but lack bioactive properties, hence the development of calcium silicate sealers. Objective: To compare the push-out bond strength and failure mode of AH Plus® Bioceramic and Ceraseal sealers with AH Plus® Sealer. Methods: Thirty premolars were divided into three groups for root canal preparation and obturation with AH Plus® Bioceramic (group 1), Ceraseal (group 2), and AH Plus® (group 3). The samples were incubated at 37°C for seven days, then cut at the apical and medial third. Push-out bond strength and failure mode were analyzed. Results: AH Plus® Bioceramic demonstrated significant differences in push-out bond strength and failure mode values compared to AH Plus® and Ceraseal. Ceraseal and AH Plus® were not significantly different. Analysis of failure mode descriptions by two observers showed high data reliability. AH Plus® Bioceramic had a predominance of mixed failures, whereas Ceraseal and AH Plus® had equal percentages of mixed and cohesive failures. Conclusion: All sealer groups showed good adhesion to the dentin surface, although the push-out bond strength value of AH Plus® Bioceramic sealer was the lowest among the groups."

"Wilayah penelitian terletak di Desa Cihaur, Kecamatan Simpenan, Kabupaten Sukabumi. Desa Cihaur merupakan salah satu daerah yang memiliki potensi timbal-emas karena area tersebut dilalui oleh jalur mineralisasi Pegunungan Selatan. Formasi yang menyusun area penelitian adalah formasi Jampang. Pada area penelitian tersingkap batuan breksi yang secara genetik belum diketahui jenisnya. Oleh karena itu, dilakukan studi mengenai Karakteristik breksi untuk mengetahui jenis dan keterkaitannya terhadap mineralisasi sehingga potensi logam ekonomis dapat diketahui dan dijadikan bahan pertimbangan eksplorasi. Metode yang digunakan pada penelitian adalah analisis petrologi pada 18 titik lubang bor, analisis petrografi sebanyak 9 sampel, dan analisis mineragrafi sebanyak 7 sampel. Berdasarkan hasil analisis didapatkan bahwa terdapat 4 jenis breksi yang menyusun wilayah penelitian, yaitu breksi vulkanik, breksi hidrotermal, breksi magmagtik-hidrotermal, dan breksi tektonik. Jenis mineralisasi yang ditemukan terdiri dari kelompok sulfida dan oksida. Kehadiran mineralisasi cukup melimpah pada breksi hidrotermal. Keterkaitan antara breksi dengan mineralisasi terletak pada genesanya. Proses keterbentukan menentukan komposisi klast dan matriks, permeabilitas, dan komposisi fluida. Parameter-parameter tersebut juga menjadi kontrol alterasi dan mineralisasi.

The research area is located in Cihaur Village, Simpenan District, Sukabumi Regency. Cihaur Village is one of the areas that has lead-gold potential because the area is traversed by the Southern Mountains mineralization route. The formation that makes up the research area is the Jampang formation. In the research area, breccia rocks were exposed, the genetic type of which is unknown. Therefore, a study was carried out on the characteristics of breccia to determine the type and its relationship to mineralization so that the potential for economic metals can be known and used as exploration consideration. The methods used in the research were petrological analysis at 18 drill hole points, petrographic analysis of 9 samples, and mineragraphic analysis of 7 samples. Based on the analysis results, there are four types of breccia in the research area, namely volcanic breccia, hydrothermal breccia, magmagtic-hydrothermal breccia, and tectonic breccia. The type of mineralization found consists of sulfide and oxide groups. The presence of mineralization is quite abundant in hydrothermal breccia. The relationship between breccia and mineralization lies in its genesis. The formation process determines the clast and matrix composition, permeability, and fluid composition. These parameters also control alteration and mineralization."

Latar Belakang: Siler kalsium silikat bersifat hidrofilik, berikatan secara kimia ke dentin,  membentuk hidroksiapatit, memiliki waktu kerja dan settingideal, dan tidak terjadi penyusutan. Siler resin epoksi yang banyak digunakan saat ini memiliki kekurangan berupa adanya penyusutan saat mengeras. Evaluasi adaptasi siler dapat menentukan kemampuan kerapatan suatu siler. Salah satu metode untuk mengevaluasi kemampuan kerapatan siler adalah dengan Scanning Electron Microscopy (SEM). Tujuan: Menganalisis perbedaan adaptasi siler pada sepertiga tengah dinding saluran akar antara siler berbahan dasar kalsium silikat dengan resin epoksi.Metode: Tiga puluh dua sampel gigi premolar mandibula dibagi menjadi dua kelompok, yaitu kelompok 1: siler resin epoksi dan kelompok 2: siler kalsium silikat. Sampel dipreparasi dan diobturasi dengan siler berbahan dasar kalsium silikat dan resin epoksi. Selanjutnya, gigi dipotong vertikal dan disiapkan untuk analisis adaptasi siler menggunakan SEM. Data tersebut dianalisis secara statistik dengan uji Chi-squareHasil Penelitian: Tidak terdapat perbedaan bermakna antara adaptasi siler kalsium silikat dan resin epoksi secara statistik (p>0.05). Partikel resin epoksi secara keseluruhan tampak berukuran lebih besar dibandingkan dengan kalsium silikat. Kesimpulan: Tidak terdapat perbedaan adaptasi siler secara statistik antara siler berbahan dasar kalsium silikat dengan resin epoksi pada sepertiga tengah dinding saluran akar, namun secara klinis sampel siler kalsium silikat lebih sedikit menunjukkan gap/ celah dan lebih banyak yang berpenetrasi ke dalam tubuli dentin dinding saluran akar.


Background: Calcium silicate sealer is hydrophilic, chemically bonded to dentin, forms hydroxyapatite, has an ideal working and setting time, and does not shrink. The epoxy resin sealer that is widely used today has the disadvantage of shrinkage when hardening. Evaluation of the adaptation of the sealer can determine the sealing ability of a sealer. One of the method for evaluating the sealing ability of a sealer is Scanning Electron Microscopy (SEM). Objective: To analyze differences in the adaptation of sealers in middle third of root canal wall between the calcium silicate and epoxy resin based sealer. Methods: Thirty-two mandibular premolar teeth samples were divided into two groups, that are group 1: epoxy resin sealer and group 2: calcium silicate sealer. Samples were prepared and obturated with calcium silicate and epoxy resin based sealer. Next, the teeth were cut vertically and prepared for analysis of the sealer adaptation using SEM. The data was analyzed statistically by Chi-square test. Results: There was no significant difference between the adaptation of calcium silicate and epoxy resin sealer statistically (p> 0.05). Overall epoxy resin’s particles appear larger than calcium silicate. Conclusion: There was no statistical difference in the adaptation of sealers between calcium silicate and epoxy resin based sealer in middle third of root canal wall, but clinically fewer calcium silicate sealer samples showed gaps and more penetrated into dentinal tubules of root canal wall.

"Latar Belakang: Siler biokeramik berbasis kalsium silikat diketahui memiliki biokompabilitas tinggi, mampu beradhesi dengan dinding saluran akar serta dapat menginduksi respon osteogenik, yang dikategorikan sebagai material biomimetik. Akan tetapi, siler biokeramik memiliki kekurangan pada sifat fisiknya. Kitosan larut air merupakan bentuk modifikasi kitosan yang memiliki keunggulan sebagai antioksidan, antibakteri, berperan dalam penyembuhan lesi dan regenerasi jaringan serta sebagai dapat memperbaiki sifat fisik semen. Perpaduan kedua bahan dapat menciptakan semen saluran akar biomimetik.
Tujuan: Melakukan uji karakteristik, sifat fisik dan biologis terhadap novel siler hibrida biokeramik-kitosan larut air (BCC) sebagai semen biomimetik saluran akar.
Metode: Novel siler hibrida BCC dimanipulasi dari semen biokeramik (BC) yang telah melalui proses ball-milling dan sintering, kemudian dicampur kitosan larut air dengan W/P 0,4. Empat variabel penelitian, yaitu semen biokeramik BC, novel siler hibrida BCC, siler biokeramik dan siler epoksi resin dilakukan uji karakterisasi (XRD, SEM/EDS), uji sifat fisik (setting time, daya alir, film thickness), serta uji biologis (sitotoksisitas dan bioaktivitas terhadap hPDLSCs).
Hasil: Novel siler hibrida BCC mengandung unsur dan puncak kristalin yang serupa dengan siler biokeramik (Sure-Seal Root™), memiliki bentuk partikel yang cenderung globular dan homogen dengan jarak antarpartikel lebih rapat serta ukuran partikel deskriptif yang lebih besar dibandingkan Sure-Seal Root™ dan AH Plus® tetapi lebih kecil dibandingkan semen biokeramik BC. Hanya semen biokeramik BC dan novel siler BCC yang memiliki rasio Ca/Si/P. Novel siler BCC menunjukkan perbedaan setting time, daya alir dan film thickness yang bermakna dengan semen biokeramik BC, Sure-Seal Root™ dan AH Plus®. Keempat kelompok menunjukkan sitotoksisitas rendah terhadap hPDLSCs. Bioaktivitas novel siler BCC relatif lebih tinggi dibandingkan semua kelompok perlakuan dan kontrol.
Kesimpulan: Novel siler hibrida BCC berpotensi memberikan implikasi klinis yang baik, menunjukkan sifat fisik yang mendekati standar semen saluran akar dan memiliki bioaktivitas sebagai semen biomimetik saluran akar.

Background: Currently, bioceramic sealers with calcium silicate based have been developed and show high biocompatibility, are able to adhere to root canal dentin and can induce an osteogenic response, which can be categorized as biomimetic materials. On the other hand, water-soluble particle (WSP) chitosan, one of chitosan derivatives, has advantages as an antioxidant, antibacterial, plays a role in wound healing and tissue regeneration as well as a thickening agent. The combination of these two materials can create a biomimetic endodontic sealer.
Objective: To examine the characteristics, physical and biological properties of novel bioceramic-chitosan hybrid sealer (BCC) as biomimetic endodontic sealer.
Methods: Novel BCC sealer were manipulated from bioceramic cement (BC) which had been synthesized through a ball-milling and sintering process, then mixed with WSP chitosan with a W/P of 0,4. Four variables, namely novel BCC sealer, BC bioceramic cement, bioceramic and epoxy resin sealer were tested characterization (XRD, SEM/EDS), physical properties (setting time, flow, film thickness), and biological tests (cytotoxicity and bioactivity on hPDLSCs).
Results: Novel BCC sealer showed bioceramic elements and crystalline peaks similar to bioceramic sealer (Sure-Seal Root™), had a particle shape that tends to be globular and homogeneous with descriptive particle size larger than Sure-Seal Root™ and AH Plus® but smaller compared to BC bioceramic cement. Only BC bioceramic cements and novel BCC sealer had Ca/Si/P ratios. Novel BCC sealer showed significant differences in setting time, flow, and film thickness with BC bioceramic cements, Sure-Seal Root™ and AH Plus®. The four groups showed low cytotoxicity to hPDLSCs. The bioactivity of novel BCC sealer was relatively higher among other groups and control group.
Conclusion: Novel BCC hybrid sealer has good clinical implications, exhibit physical properties close to standard root canal cements and have bioactivity as root canal biomimetic sealer.
