Abstract

Background: Sodium hypochlorite produces free oxygen and free radicals that cause damage to dentin collagen. Combination with Sodium thiosulfate with the aim of improving root canal hygiene and restoring the oxidizing effect on the dentin surface.The apical third of the root canal is the most difficult part, due to its narrower anatomy, curvature and frequent branching of the root canal. Method: The study used 30 specimens which were divided into 3 groups, group I was irrigated with 2.5% NaOCl, 5% sodium thiosulfate and saline, group II was irrigated with 2.5% NaOCl, 10% sodium thiosulfate and saline and group III was irrigated with 2.5% NaOCl and saline. The tooth length 14 mm measured from apical to crown. The crown down technique was prepared using the M3 Pro gold file. Observation of the level of cleanliness of the root canal was carried out using a Scanning Electron Microscope (SEM) with 5000x magnification at apical third . The results of micrographic photographs are then given a score of 1-4.Result: Irrigated with 5% and 10% sodium thiosulfate showed no significant difference.Conclusion: The differences is not significant, 2,5% irrigation with sodium thiosulfate resulted in a higher cleanliness apical third of the root canalthan 2,5% NaOCl irigation with saline

Abstract

Background: Discoloration of composite restorations may affecting aesthetic appearance. The aging-process and surface roughness may influence color changes. A nanofilled self-adhesive protecting coating has been developed for coating tooth restoration and expected to prolong the longevity of restoration. To evaluate the effect of nanofilled self-adhesive protective coating on the surface roughness and color-changes of flowable and packable composite after aging condition. Methods: The total of 40 discs (15x2mm) and 60 boxes (20×10× 2mm) specimens from flowable and packable composite were used. A half of the specimens was coated by using protective-coating. The reflectance chromameter was used to measure the color baseline. Afterward, the specimens were subjected into aging process by immersing in artificial saliva and carbonated drink (37oC,7d). The color changes were calculated based on the [CIE L*a*b*].For surface roughness, box-shaped specimens were measured in fresh condition, after aging conditions. Results: The color change ranged from 0.49 to 2.31. Applying protective-coating was associated with a significant decrease in the color-changes and surface roughness after aging. The changes of three color coordinates resulted in significant differences for both composite, with and without protective coating application. Conclusion: The application of protective-coating decrease the color-changes and surface roughness of flowable and packable composite-resin.
