"Latar Belakang: Saat ini perawatan pulpa vital mengacu pada konsep minimal intervensi, yaitu dengan meninggalkan lapisan affected dentin saat ekskavasi karena masih terdapat ikatan silang kolagen sehingga dapat dilakukan upaya remineralisasi. Remineralisasi melalui aplikasi material bioaktif Mineral Trioxide Aggregate (MTA) belum dapat menghasilkan karakteristik dentin menyerupai dentin normal karena pembentukan mineral hanya terjadi pada ruang ekstrafibrillar. Penggunaan material analog protein non kolagen dibutuhkan untuk menstabilkan nano Amorphous Calcium Phosphate (ACP) agar dapat memasuki ruang intrafibrillar, salah satunya menggunakan Carboxymethyl Chitosan (CMC).Tujuan: mengevaluasi remineralisasi dentin pada permukaan dentin terdemineralisasi setelah aplikasi material MTA dan material modifikasi MTA-CMC dengan melihat morfologi permukaan dan komposisi ion pada dentin.Metode: remineralisasi dilakukan melalui aplikasi material MTA, MTA-CMC 5% dan 10% selama 14 hari pada permukaan sampel dentin yang terdemineralisasi. Pengamatan morfologi dilakukan dengan Scanning Electron Microscope (SEM) dan konfirmasi komposisi ion dengan Energy Dispersive X-ray Spectroscopy (EDX).Hasil: terdapat perbedaan morfologi pada permukaan dentin setelah dilakukan remineralisasi melalui aplikasi MTA, MTA-CMC 5%, dan MTA-CMC 10% selama 14 hari yang dievaluasi menggunakan SEM. Hasil analisis EDX mengonfirmasi adanya peningkatan kandungan kalsium dan fosfor pada permukaan dentin yang diremineralisasi dengan material MTA-CMC.Kesimpulan: remineralisasi melalui aplikasi material modifikasi MTA-CMC dapat memengaruhi morfologi permukaan dan komposisi ion pada permukaan dentin yang terdemineralisasi.

Background: Vital pulp treatment refers to the concept of minimal intervention by preserving the affected dentin layer in the excavation process because there are still collagen cross-linked to induce remineralization. Remineralization through the application of bioactive material Mineral Trioxide Aggregate (MTA) produce different dentin characteristics to normal dentin because mineral formation only occurs in the extrafibrillar space. The use of non-collagen protein analog materials is needed to stabilize the nano Amorphous Calcium Phosphate (ACP) to get into the intrafibrillar space, one of which is Carboxymethyl Chitosan (CMC).

Objective: To evaluate dentin remineralization on the surface of demineralized dentin after the application of MTA and MTA-CMC modified material by looking at the surface morphology and ionic composition of the dentin.

Methods: The remineralization was carried out through the application of MTA,MTA-CMC 5%, MTA-CMC 10% materials for 14 days on the surface of demineralized dentin samples. Morphological observations were carried out by Scanning Electron Microscope (SEM) and confirmation of ion composition by Energy Dispersive X-ray Spectroscopy (EDX). Results: there were morphological differences on the dentin surface after remineralization through the application of MTA, MTA-CMC 5%, and MTA-CMC 10% for 14 days which were evaluated using SEM. The results of the EDX analysis confirmed an increase in the content of calcium and phosphorus on the dentin surface remineralized with MTA-CMC material.

Conclusion: remineralization through the application of MTA-CMC modified material can affect the surface morphology and ion composition on the demineralized dentin surface."

Background: Mineral trioxide aggregates have been used in various endodontic treatments because of the sealing ability, biocompatibility, bioactivity, and antibacterial properties. However, MTA cement has several disadvantages such as long setting time, sandy consistency, and relatively low mechanical strength. Synthetic and natural polymers have been investigated as additives in MTA cement and could improve its handling characteristic. Water soluble chitosan is a natural polymer with excellent bioactivity, biocompatibility, biodegradability and soluble at physiological pH. 

Objectives: This study aimed to determine the effect of adding water-soluble chitosan to the compressive strength of MTA

Methods: The specimens were divided into three groups; MTA, MTA with the addition of 5% water soluble chitosan (MTA-CW5), and MTA with the addition of 10% water soluble chitosan (MTA-CW10). The compressive strength measurement was carried out using a universal testing machine after four days incubation at 37°C and 100% humidity.

Result: There were significant different mean values of the compressive strength between three groups (one-way ANOVA test). Post Hoc Bonferroni test showed significant differences in compressive strength between the MTA-CW5 and MTA group, the MTA-CW10 and MTA group, also the MTA-CW 5 and MTA-CW10 group.

Conclusion: The addition of 5% and 10% water-soluble chitosan could increase the compressive strength of MTA cement. "

Background: Enterococcus faecalis plays a significant role in the etiology of persistent periapical lesion and can survive from chemomechanical preparation of the root canal. Therefore, three-dimensional obturation of the root canal with sealers that have antimicrobial activity must be performed to completely eliminate microorganisms from the root canal. Calcium hydroxide and mineral trioxide aggregate sealers are biocompatible and able to release hydroxyl ion thus creating alkaline environment that is responsible for their antimicrobial properties. The aim of this present study was to evaluate the antimicrobial activity of mineral trioxide aggregate and calcium hydroxide sealer on E.faecalis after different periods of contact time (fresh, 1 day, 7 day after sealer preparation).

Methods: Antimicrobial activity of MTA and Ca(OH)2 sealer on E.faecalis (ATCC 29212) was assessed by direct contact test (DCT). Each sealer was prepared and directly exposed to E.faecalis immediately, 1 day and 7 day after sealer preparation, and BHI broth medium was added. The microbial suspension was poured in the blood agar plates and incubated for 24 hours. The colonies grown on the plates were counted (CFU/ml). The data were analyzed with one way Anova and Post Hoc test.

Results: MTA sealer on 1 and 7 day after sealer preparation was greatest at diminishing microbial colonies with no significant difference with Ca(OH)2 sealer on 1 day after sealer preparation.

Conclusion: MTA sealer had constant antimicrobial activity on E.faecalis compared to Ca(OH)2 sealer. On the other hand, Ca(OH)2 sealer possessed decreasing antimicrobial activity overtime. Greatest antimicrobial activity on E.faecalis was provided by MTA sealer on 1 and 7 day after sealer preparation and Ca(OH)2 sealer on 1 day after sealer preparation. "

Background: Application of Mineral Trioxide Aggregate (MTA) as remineralization agent of affected dentin which holds a vital role in the preservation of tooth structure has been widely used in clinical practice, however it’s only capable of generating extrafibrillar remineralization resulting in the inability to produce dentin with mechanical properties resembling sound dentin. Carboxymethyl Chitosan (CMC) is a natural biomaterial developed as analogue of dentin non-collagenous proteins to inhibit the spontaneous precipitation of calcium-phosphate produced by the interaction of dentin with remineralization agent so that intrafibrillar remineralization can be accomplished.

Objective: To evaluate hydroxyapatite crystals characteristic and assess the microhardness of demineralized dentin after 14 days application of CMC-modified MTA.

Method: Remineralization was performed by the application of MTA, MTA-CMC 5%, and MTA-CMC 10% on demineralized dentin samples. During the remineralization process, root canals of tooth models were immersed in phosphate-buffered saline solution. Hydroxyapatite crystals’ characteristic was observed by X-ray Diffractometer, while dentin microhardness score was assessed by Vickers Hardness test.

Result: Formation of hydroxyapatite crystals was identified in MTA and MTA-CMC samples. Highest degree of crystallinity was found in MTA-CMC10% sample. Microhardness score of demineralized dentins in MTA-CMC 5% group and MTA-CMC 10% group was significantly higher than those in MTA group.

Conclusion: CMC-modified MTA application on demineralized dentin in 14 days was found effective in initiating hydroxyapatite formation with higher degree of crystallinity and increasing the microhardness of demineralized dentin."
