Effect of thiourethane filler surface functionalization on stress, conversion and mechanical properties of restorative dental composites

Despite the low annual failure rates (1 –3%) observed for composite restorations in posterior teeth, with most failures observed being related to secondary caries and fractures of the tooth structure or restorative materials, on average, restorations last about 10 years in service [1–3]. Secondary caries is significantly affected by r isk factors associated to the patients [4–6], but the presence of defects at the restoration margins can increase the likelihood of bacterial recolonization and reestablishment of the disease in the region [7–9].
