Scanning electron microscopy analysis of marginal adaptation of composite resines to enamel after using of standard and gradual photopolimerization
Introduction. Bonding between composite and hard dental tissue is most commonly assessed by measuring bonding strength or absence of marginal gap along the restoration interface. Marginal index (MI) is a significant indicator of the efficiency of the bond between material and dental tissue...

| description | Introduction. Bonding between composite and hard dental tissue is most
commonly assessed by measuring bonding strength or absence of marginal gap
along the restoration interface. Marginal index (MI) is a significant
indicator of the efficiency of the bond between material and dental tissue
because it also shows the values of width and length of marginal gap.
Objective. The aim of this investigation was to estimate quantitative and
qualitative features of the bond between composite resin and enamel and to
determine the values of MI in enamel after application of two techniques of
photopolymerization with two composite systems. Methods. Forty Class V
cavities on extracted teeth were prepared and restored for scanning electron
microscope (SEM) analysis of composite bonding to enamel. Adhesion to enamel
was achieved by Adper Single Bond 2 - ASB (3M ESPE), or by Adper Easy One -
AEO (3M ESPE). Photopolymerization of Filtek Ultimate - FU (3M ESPE) was
performed using constant halogen light (HIP) or soft start program (SOF).
Results. Quantitative and qualitative analysis, showed better
mikromorphological bonding with SOF photopolymerization and ASB/FU composite
system. Differences in MI between different photopolymerization techniques
(HIP: 0.6707; SOF: 0.2395) were statistically significant (p<0.001), as well
as differences between the composite systems (ASB/FU: 0.0470; AEO/ FU:
0.8651) (p<0.001) by two-way ANOVA test. Conclusion. Better marginal
adaptation of composite to enamel was obtained with SOF photopolymerization
in both composite systems. |
