Cure profiles of visible-light-cured Class II composite restorations in vivo and in vitro.
The degrees of conversion of posterior composite material in Class II restorations performed in vivo and in vitro were studied by means of the Raman spectroscopy method. Class II restorations in 13 contralateral pairs of premolars were analyzed. The average difference of the ratio I 1610 cm-1/I 1640 cm-1 between the in vivo- and in vitro-performed restorations was 0.42. This indicates a higher grade of conversion in the in vivo situation.
