“…Stainless steel displayed the highest maximum contraction rate which was about 8.3 times higher than that of PMMA. Such a large value for the stiff steel material was caused by its high Young's modulus as compared to low modulus of PMMA ring 9) . For the human molar tooth, its maximum stress and maximum contraction rate were ranked intermediate between and statistically different from stain steel and PMMA.…”

“…Using the elastic ring method as previously described 1,8,9) , polymerization contraction stress developed at composite restoration margin (i.e., composite-substrate interface on the inner surface of ring substrate) was measured based on circumferential stress on the outer surface of ring substrate. Measurements were performed seven times for each ring substrate.…”

“…Young's moduli (E) were assumed as follows for a mixed ratio of 1:1 of dentin and enamel layers 11) : EPMMA=3.1 9) , Estainless steel=202 GPa 9) , and Etooth=49 GPa. It must be highlighted that the thus-obtained contraction stress at composite restoration margin was not a true shrinkage stress generated within the composite resin based on homogeneous and adequate bonding 1) between composite resin and ring substrate.…”

“…For example, AE hits and amplitudes were used to elucidate the microfracture mechanisms of dental composite resins 7) . In our previous works 8,9) , AE signals were monitored in real time to observe the marginal disintegration process taking place in the interior of restored tooth specimens. Results showed that AE events could be used as a nondestructive evaluation index for marginal failures caused by polymerization contraction stress 8,9) .…”

Results showed that AE events could be used as a nondestructive evaluation index for marginal failures caused by polymerization contraction stress 8,9) . In separate studies by Li et al 6) and Liu et al 10) , monitoring of AE events revealed that the higher the shrinkage stress, the more likely it was for interfacial debonding to occur in composite resin restorations during curing.…”

In this study, a nondestructive method based on acoustic emission (AE) analysis was developed to evaluate the marginal failure states of dental composite restorations. Three types of ring-shaped substrates, which were modeled after a Class I cavity, were prepared from polymethyl methacrylate, stainless steel, and human molar teeth. A bonding agent and a composite resin were applied to the ring-shaped substrates and cured by light exposure. At each time-interval measurement, the tooth substrate presented a higher number of AE hits than polymethyl methacrylate and steel substrates. Marginal disintegration estimations derived from cumulative AE hits and cumulative AE energy parameters showed that a signification portion of marginal gap formation was already realized within 1 min at the initial light-curing stage. Estimation based on cumulative AE energy gave a higher level of marginal failure than that based on AE hits. It was concluded that the AE analysis method developed in this study was a viable approach in predicting the clinical survival of dental composite restorations efficiently within a short test period.
