Introduction White spot lesions (WSLs) are opacities formed due to decalcification occurring in the enamel's subsurface layer. These lesions are most commonly seen in patients during and after fixed orthodontic treatment due to undisturbed accumulation of plaque. Other factors that can predispose to WSLs are enamel hypomineralization, hypomaturation, hypoplasia, and disruption in the levels of salivary calcium, phosphate, bicarbonate, and fluoride.

Multiple MMP inhibitors (MMPIs) are known to counteract this degenerative mechanism, thereby preserving bond strength and promoting the longevity of resin-based restorations. Additionally, literature suggests that certain MMPI materials possess antimicrobial/anticariogenic properties, potentially reducing the risk of secondary caries development.

Methodology A total of 96 single-rooted premolars were decoronated and obturated and post spaces were prepared for 9 mm. The canals were irrigated with 17% ethylenediaminetetraacetic acid followed by distilled water.

Methodology A total of 120 samples were involved in the study, which were split into two experimental groups. For evaluation of each mechanical property, 20 samples were included, of which 10 samples were used for evaluating the properties of Cention N and 10 samples were used for TiOnanoparticles-enriched Cention N.
