Abstract

Immediate Dentin Sealing (IDS) is a conservative procedure performed to protect the exposed dentin surface after tooth preparation, especially for indirect restorations. Indirect restorations are a common procedure in dentistry for replacing the crown structure of teeth, including various types such as jacket crowns, bridge prostheses, endo crowns, inlays, and veneers. The tooth preparation process can expose dentin tubules, which can trigger pulp tissue irritation and the risk of infection, as well as interfere with the adhesion of the final restoration. Post-IDS surface treatment methods can help enhance the bonding strength. The research aims to investigate the influence of different post-IDS surface treatment on the shear bond strength of lithium disilicate.The study involved 30 upper premolar teeth, divided into three groups. After crown portion buccal surface preparation, all samples underwent IDS, followed by immersion in water and 24-hour incubation. Subsequently, each group received a specific surface treatment: Group I with nylon brush, Group II with nylon brush + pumice, and Group III with sandblasting using aluminum oxide. Lithium disilicate was then cemented on all samples, followed by another 24-hour incubation before shear bond strength testing. Shear bond strength values in MegaPascals (MPa) were analyzed using one-way ANOVA and post hoc Games-Howell tests with a 95% confidence level.The statistical analysis revealed a significant influence of the different treatment groups on shear bond strength (p < 0.05). In conclusion, this study demonstrates a significant impact of varying post-IDS surface treatments on the shear bond strength of lithium disilicate.

Abstract

Background: The smear layer may interfere with the penetration of the root canal sealer. Final irrigation is known to improve chelating agents' ability in smear layer removal. This study aimed to compare the effect of various materials and final irrigation techniques on the penetration depth of bioceramic silers in the apical third of the tooth.Method: This study used 45 premolars that were prepared with a rotary instrument and then randomly divided into three experimental groups (n=15). Group 1 used 17% EDTA as the final irrigation material, group 2 used Novel Silver Citrate, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5), with subgroup A using manual agitation technique, subgroup B using sonic agitation, and subgroup C using ultrasonic agitation. The teeth were then obturated using a bioceramic sealer. Teeth then cut vertically for observation and measurement  sealer penetration using a stereo microscope with a magnification of 30x followed by observation using SEM at 1000x magnification. data where analyzed using a two-way ANOVA followed by an LSD Post Hoc test, with a significance level of 95%.Result: Two-way ANOVA showed significant differences in materials, techniques, and material-technique interactions (p<0,05).Conclusion: This study concludes that there is an effect of material, technique, and material-technique interaction of final irrigation on the penetration of bioceramic sealer into the dentinal tubules, Combination of 0.2% chitosan nanoparticles and sonic agitation as material and final irrigation technique resulted in the most longest penetration of bioceramic sealer into dentinal tubules.

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.
