"Latar Belakang: Salah satu material remineralisasi yang banyak digunakan adalah semen ionomer kaca (SIK). Namun dentin terdemineralisasi sesudah aplikasi SIK memiliki sifat mekanis yang berbeda dan lebih rendah daripada dentin normal karena remineralisasi yang terjadi adalah remineralisasi interfibril. Material carboxymethyl chitosan (CMC) bertindak sebagai analog protein nonkolagen yang mampu menstabilisasi nanocluster amorphous calcium phosphate (ACP) dalam proses remineralisasi intrafibril. Tujuan: Mengetahui pengaruh aplikasi modifikasi SIK-CMC5% dan SIK-CMC10% pada dentin terdemineralisasi terhadap kekerasan mikro, fasa mineral dan derajat kristalinitas dentin. Metode: Material SIK dilakukan pencampuran dengan CMC pada rasio 5% dan 10% menghasilkan SIK-CMC5% dan SIK-CMC10%. Kemudian, demineralisasi pada kavitas dentin terdemineralisasi dilakukan dengan aplikasi material SIK, SIK-CMC5% dan SIK-CMC10%. Akar gigi direndam dalam cairan phosphate-buffered saline selama 14 hari. Remineralisasi dentin dievaluasi dari kekerasan mikro melalui uji Vickers dan penilaian fasa mineral dan derajat kristalinitas dentin dari uji X-Ray Diffraction (XRD). Hasil: Kekerasan mikro dentin pada kelompok SIK-CMC5% dan SIK-CMC10% meningkat dibandingkan pada kelompok SIK. Pembentukan kristal hidroksiapatit ditemukan pada sampel SIK dan SIK-CMC, dengan derajat kristalinitas tertinggi pada sampel SIK-CMC10%. Kesimpulan: Semen Ionomer Kaca modifikasi Carboxymethyl Chitosan 10% lebih efektif dalam meningkatkan nilai kekerasan mikro dan mempengaruhi pembentukan fasa mineral kristal hidroksiapatit dan derajat kristalinitas.

Background: One of the widely used remineralization materials is glass ionomer cement (GIC). However, demineralized dentine after GIC application has different and lower mechanical properties than normal dentin because the remineralization that occurs is interfibril remineralization. Carboxymethyl chitosan (CMC) acts as noncollagenous protein analog that can stabilize amorphous calcium phosphate (ACP) nanoclusters in intrafibril remineralization. Objective: To determine the effect of the application of modified GIC-CMC5% and GIC-CMC10% on the microhardness, mineral phase and degree of crystallinity of demineralized dentin. Methods: GIC material was mixed with CMC at ratio 5% and 10% to produce GIC-CMC5% and GIC-CMC10%. Remineralization of demineralized dentin cavity was carried out by applying GIC, GIC-CMC5% and GIC-CMC10% for 14 days. Remineralization was evaluated from microhardness value through Vickers test and assessment of mineral phase and degree of dentin crystallinity from X-Ray Diffraction (XRD) test. Results: Dentin microhardness in the GIC-CMC5% and GIC-CMC10% was increasing compared to the CIC group. The formation of hydroxyapatite crystals was found in the GIC and GIC-CMC samples with the highest degree of crystallinity in the GIC-CMC10% sample. Conclusion: Modified Glass Ionomer Cement with 10% Carboxymethyl Chitosan is more effective in increasing the microhardness value and affecting the formation of the hydroxyapatite crystalline mineral phase and the degree of crystallinity."

"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."

"The present study investigated the effect of non-surgical periodontal therapy on serum level of anti-cardiolipin antibodies (aCLA), which are potentially involved in the pathogenesis of cardiovascular diseases in periodontal patients. Twenty volunteers (11 females and 9 males) with the mean age of 40.55 years participated in this study. Generalized chronic periodontitis was diagnosed through clinical periodontal examination at baseline visit. This examination included measuring the probing pocket depth and clinical attachment loss. Plaque index and gingival index were also recorded. After baseline examination, all the subjects received full-mouth non-surgical periodontal treatment. Subjects returned for a final visit 6 weeks after the last session of scaling for reevaluation of the periodontal parameters. At baseline and final visits 2 ml of venous blood was collected from each patient and an available commercially enzyme-linked immunosorbent assay was used for analyzing aCLA (IgM and IgG). The collected data were analyzed using the paired sample t test. Mean levels of both forms of aCLA, before and after treatment, showed statistically significant difference (P = 0.003 for IgM and P = 0.001 for IgG). In addition, study results showed significant reductions in periodontal parameters after non-surgical periodontal therapy (P < 0.001). The results of this study suggested that successful periodontal therapy can improve the serum level of one of the inflammatory biomarkers involved in the cardiovascular problems."

"Root development of permanent teeth is disturbed in survivors of childhood cancer. Cyclophosphamide (CY) is a cytostatic drug commonly used for chemotherapy in children with cancer. This study aimed to evaluate the effects of CY on the development of molar teeth until the completion of occlusion in young mice, focusing on Hertwig’s epithelial root sheath (HERS). We treated thirty-two 12-day-old ICR mice with CY (100 mg/kg; 100-CY group), and 36 control mice with saline. At 12, 14, 16, 20, 24, 27, 39, 60, and 76 days of age, the mandibular molars were removed. Soft X-ray radiographs were obtained in lateral projection. The root/crown length (R/C) ratio of the first molar was calculated. Serial sagittal sections were prepared and histomorphological hematoxylin and eosin (HE) staining and immunohistochemical (cytokeratin) studies were performed. The R/C ratio of the 100-CY group (0.78) was smaller than that of the control group (1.23) at 76 days (p < 0.05, t test). While all roots developed further after injection, microscopic examination showed that the roots of the first molars that developed in the 100-CY group were shorter than those in the control group. In addition, experimental mice showed apical closure of the roots. By 20 days after injection, the HERS had disappeared from the root surface in the 100-CY group. In conclusion, this study indicates that CY can induce a defect in HERS and cause early loss of HERS. Disruption of the epithelial sheath inhibits normal root formation, and it could cause irreversible short-root development."
