Abstract

Indirect resin composite veneer restoration (VIRK) is used as esthetic restoration for anterior teeth. Attachment between restoration and enamel surface was obtained using multi-step (MS) resin cement. Recently, a one step self-adhesive dual-cured resin cement (SADRC) was introduced. Determine failure analysis of VIRK bonded to enamel using MS resin cement and SADRC. Twenty specimens of buccal surface of enamel premolar were used. The specimens were flattened using silicon carbide no.2000. VIRK cylindrical specimens (diameter 3mm, thickness 3mm), were light-cured in Solidilite chamber (Shofu, Japan) for 3 minutes. VIRK specimens were then divided into: Group I with Multi-step resin cement (n=10) and Group II with SADRC (n=10). After 24h in incubator (37oC), Shear Bond Strength (SBS) were tested using Universal Testing Machine(Shimadzu AG5000). Failure analysis was determine using Stereomicroscope (Nikon, Japan) and Scanning Electron Microscope ( JEOL JSM 6510LA, Japan). Data were analyzed using Independent Sample T-Test (p<0.05). The average SBS value of group VIRK+MS was (16.97 + 7.67 MPa) higher than VIRK+SADRC (7.17 + 3.67 MPa). VIRK+Multi-step group has mixed failure, while VIRK+SADRC group has adhesive failure. Mixed failure shows strong bond between VIRK and enamel using Multi-step resin cement.

Abstract

The implementation of nano technology on resin modified glass ionomer cement (RMGIC) results in the latest restorative material which is known as Nano-ionomer. The surface texture of the restoration is one of the most important factors that influences the successful of the material usage. Surface irregularity may cause plaque retention, surface discoloration, and gingival irritation. Objective: To analyze the effect of brushing with toothpastes to the surface roughness of Nano-ionomer and RMGIC. Specimens of Nano-ionomer and RMGIC are brushed with distilled water, anti-cavity toothpaste, and whitening toothpaste (6 Specimens each) for 60 minutes, every 10 minutes the surface roughness are measured with Surface Roughness Tester (Ra). The data are statistically analyzed using Paired-samples t-Test, One-way ANOVA, and Independent-samples t-Test. There is an increase in the surface roughness of both group samples after brushing. As for RMGIC, there is a significant difference between the surface roughness values after brushing with distilled water, anti-cavity toothpaste, and whitening toothpaste, while for Nano-ionomer, the difference is not significant. Once compared, there is a significant difference between the surface roughness increase of RMGIC and Nano-ionomer (p<0.05) which can be seen after brushing for 60 minutes. The increase of surface roughness of RMGIC is significantly higher than Nano-ionomer.
