Effect of root canal sealers on human periodontal ligament fibroblast viability: ex vivo study
Abstrak :
The aim of the study was to compare ex vivo the toxic effects of six root canal sealers immediately after mixing or setting on human periodontal ligament fibroblasts (HPdLF). Freshly mixed (I group) or set (allowed to dry for 24 h) (II group) specimens of AH Plus Jet (AH), Apexit Plus (AP), MTA Fillapex (FL), GuttaFlow (GF), MetaSEAL Soft (META), and Tubli-Seal (TS) were prepared. HPdLF were exposed for 24 h to the specimens. 3-(4,5-dimethylthiazolo-2-yl)-2,5-diphenyltetrazolium bromide assay was used to examine the effect of the root canal sealers on mitochondrial metabolic activity. Fluorescein isothiocyanate (FITC)-annexin V (AnV) and propidium iodide staining followed by flow cytometry was used to identify the effects of the materials on cell apoptosis/necrosis. Statistical analyses were performed by one-way ANOVA followed by post hoc tests, and significance was determined at P < 0.05. Most materials from the two groups reduced the viability of the cultured cells compared with the control group (P < 0.05). Statistical analysis showed significant differences in HPdLF viability between the individual materials in each group (P < 0.001). AH and AP induced a significant increase in the percentage of apoptotic cells, while TS, FL, and META elevated the proportion of necrotic cells compared with other materials and the controls (p < 0.05). The cytotoxic effects of the tested root canal sealers (both fresh and set) on HPdLF varied. Both forms of sealers were able to cause toxic effects by inducing apoptosis and necrosis in HPdLF. The cytotoxicity of FL, META, TS was mainly associated with necrosis, while AH and AP with apoptosis.

Abstrak :
Penelitian ini dilakukan untuk mengetahui kemampuan sealing dua macam sealer, dengan liquid eugenol dan sealer tanpa eugenol sebagai perekat gutta-percha pada penutupan saluran akar. Enam puluh delapan saluran akar lures dari gigi-gigi yang baru dicabut, dipreparasi secara konvensional sampai 1 mm dari apeks dengan file no. 60. Foramen apikal ditembus dengan file no.25 untuk mendapatkan keseragaman diameter. Tiga puluh akar gigi diisi gutta-percha dengan sealer AH-26 (tanpa eugenol), dan 30 lainnya dengan gutta-percha dengan sealer proco-sol (mengandung eugenol). Empat saluran akar diisi dengan gutta-percha saja sebagai kontrol positif, 4 saluran akar lain dibiarkan kosong dengan apeks yang ditutup sticky wax sebagai kontrol negatif. Kebocoran pengisian saluran akar diukur dengan dye penetration tinta Petikan hitam, dengan interval waktu rendaman 1 dan 15 hari setelah pengerasan sealer 48 jam. Evaluasi dilakukan dengan Stereo mikroskop untuk melihat kebocoran vertikal dan horisontal. Hasil penelitian dengan tes Anova menunjukkan kemampuan sealing Proco-Sol lebih rapat secara bermakna. Waktu rendaman 1 dan 15 hari ternyata tidak mempengaruhi besar kemampuan sealing. Kesimpulan yang dapat ditarik pada penelitian ini ialah bahwa Proco-Sol memberikan kwalitas penutupan lebih rapat dibanding sealer AH-26.

Adaptasi Siler Berbahan Dasar Kalsium Silikat dan Resin Epoksi pada Sepertiga Tengah Dinding Saluran Akar = Adaptation of Calcium Silicate and Epoxy Resin Sealers in Middle Third of Root Canal Wall
Abstrak :

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-square. Hasil 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.
