Background: The discoloration of teeth, especially anterior teeth, is one of aesthetic problems. The use of tooth bleaching agents for discolored natural teeth is becoming increasingly popular. Many dentists, however, get many problems when they conduct bleaching process since there is much composite filling on patient’s anterior teeth. Although many research have focused on the discoloration of composite resin after bleaching process, the problem still becomes debatable. Purpose: The purpose of this study was to investigate the difference of the discoloration between hybrid composite and nano composite before and after the application of tooth bleaching agent, 38% hydrogen peroxide. Methods: Eighteen disk-shaped specimens (5 mm) of each of two composite resins, hybrid and nano filler, were prepared. The each group was treated 3 times and the specimens were divided into two groups consisted of 9 specimens for each, and then immersed in black tea solutions for 72 hours. Next, after having staining and bleaching processes, the color of the specimens was measured with a optic spectrophotometer by using photo with type BPY-47 and digital microvolt. The differences of the light intensity among three measurements were then calculated. Afterwards, GLM MANOVA Repeated Measure and parametric analysis (Independent t-test and Paired t-test) were then used to analyze the data. Results: After staining process, it is then known that the nano composite had more discoloration and more affected by the black tea solution than the hybrid one. Conclusion: After bleaching, the discoloration was finally removed completely from both hybride and nano filler composite resins and became brighter from the baseline color.Latar belakang: Salah satu problem estetik adalah adanya perubahan warna pada gigi anterior. Peningkatan pemakaian bahan bleaching semakin popular. Banyak dokter gigi mempunyai problem ketika mereka akan melakukan proses bleaching dan ditemukan banyak tumpatan komposit pada gigi anteriornya. Meskipun telah banyak penelitiahan yang dilakukan tetapi masalah ini masih menjadi pro dan kontra. Tujuan: Melihat perbedaan perubahan warna antara komposit hybrid dan komposit nano sebelum dan sesudah terpapar bahan pemutih gigi hidrogen peroksida 38%. Metode: Tiap kelompok mendapatkan perlakuan 3 kali. Dipersiapka 18 spesimen berbentuk tabung (5 mm) dan dibagi menjadi 2 kelompok masing-masing 9 untuk resin komposite hybrid dan komposit nano. Direndam larutan teh hitam selama 72 jam. Perubahan warna diukur dengan spektrofotometer tipe BPY-47 dan mikrovolt digital, baik sebelum, setelah perendaman larutan teh hitam dan setelah proses bleaching. Perbedaan intensitas cahaya dihitung dengan GLM MANOVA Repeated Measuse dan analisa parametrik. Hasil: Setelah perendaman teh hitam, komposit nano mempunyai perubahan warna yang lebih gelap dibandingkan komposit hybrid. Setelah bleaching, baik komposite hybrid dan komposit nano kembali ke warna aslinya. Tetapi perubahan warna komposit nano lebih besar dari pada komposit hybrid.

Background: A successful endodontic treatment is inseparable from the right choice of root canal dressing. The right choice of medicaments would result in patient satisfaction. Enterococcus faecalis (E. faecalis) and Porphyromonas gingivalis (P. gingivalis) are usually found in failed root canal treatments. Calcium hydroxide is a gold standard dressing that creates an alkaline environment in the root canal and has a bactericidal effect. Commercially, there are calcium hydroxide dressings with supporting additions, including calcium hydroxide–iodophors (CH–iodophors) and Calcium hydroxide–barium sulfate (CH–barium sulfate). Purpose: This study aimed to compare the antibacterial efficacy between CH–iodophors and CH–barium sulfate root canal dressings on E. faecalis and P. gingivalis. Methods: CH–iodophors and CH–barium sulfate were obtained commercially. E. faecalis and P. gingivalis were obtained from stock culture taken from the root canal of failed endodontic treatment. E. faecalis and P. gingivalis were cultured in Petri dishes, and for each bacterium, 12 wells were made in the media. Six wells were used for the CH–iodophors group, and six wells were used for the CH–barium sulfate group. CH–iodophors and CH–barium sulfate were deployed in the wells in E. faecalis and P. gingivalis cultured media in the Petri dishes. After incubation, the inhibition zone diameters were measured. An independent t-test was used for analysis, and the significance level was set at 5%. Results: There is a significant difference in the antibacterial efficacy of CH–iodophors and that of CH–barium sulfate on E. faecalis and P. gingivalis (p = 0.00001). Conclusion: CH–iodophors have a higher antibacterial efficacy than CH–barium sulfate on both E. faecalis and P. gingivalis.

Background: Before restoration, it is necessary to clean the cavity from the smear layer and residual bacteria such as Sreptococcus mutans using a 'gold standard' cavity cleanser, namely 2% Chlorhexidine digluconate (CHX), however CHX 2% has a disadvantage of having a toxic effect on fibroblasts, osteoblasts, myoblasts, odontoblast-like cells, Chinese hamster ovary cells, and buccal epithelial cells. The shortcomings of the 2% CHX triggered researchers to look for alternative cavity cleansers that are more biocompatible, namely cocoa peel extract because it contains of antibacterial compounds including alkaloids, flavonoids, tannins, saponins, and terponoids with a non-toxic 6% concentration. Purpose: To analyze the difference of antibacterial activity between cocoa peel extract with a concentration of 6% compared to chlorhexidine digluconate 2% against Streptococcus mutans. Methods: This research was an in vitro laboratory experimental study with the posttest only control group design which included two treatment groups, namely 6% cocoa peel extract and 2% CHX. This research was conducted using the inhibition zone diffusion method against S. mutans to see the antibacterial power of each sample. Results: There was a significant difference (p <0.05) in the mean diameter of the inhibition zone between 6% cacao peel extract, namely 11.5406 mm and CHX 2%, namely 13.2156 mm. Conclusion: Chlorhexidine digluconate 2% has a greater antibacterial power than 6% cocoa peel extract (Theobroma cacao L.) against Streptococcus mutans.

Background: Composite resins restoration is a treatment for tooth structure loss due to pathological conditions. Longevity of composite resins restoration can be affected by surface hardness restoration. Glycerin can increase surface hardness restoration with inhibit bond oxygen and free radicals on polymerization composite resins. Purpose: Analyze the increase surface hardness composite resins restoration after glycerin application before light-curing composite resins. Review(s): Of the six journals included in this literature review, five journals reported significant differences because of the obstacles in the polymerization process of the composite resin when composite contact with light-curing will activate the photoinitiator to produce highly reactive free radicals, free radicals will break the double chain carbon bonds of monomers and form single bonds of free radicals with monomers. Bonding of free radicals with monomers will produce polymeric bonds (degree of conversion) which affects the level of surface hardness of the filling. While one journal noted no significant difference in the surface hardness of composite resin after glycerin application. Conclusion: The use of glycerin before light-curing can increase the surface hardness composite resin restorations.

Background: Tooth discoloration can be treated with dental bleaching using Hydrogen peroxide (H2O2). Dental bleaching may interfere with the shear bond strength of composite resins because the remaining free radicals can affect bonding polymerization. Epigallocatcehin-3-gallate (EGCG) as an antioxidant can neutralize the free radicals produced during bleaching process. Purpose: Analyze the role of EGCG antioxidants in increasing the shear bond strength of composite resin after bleaching.. Reviews: Of the seven journals included in this literature review, six journals reported significant difference, and one journal noted no significant difference in the shear bond strength of composite resin following the EGCG application. Conclusion: The use of EGCG can increase the shear bond strength value of post-bleaching composite resin restorations.
