Objectives: To evaluate the in vivo effect of Titanium dioxide (TiO2) nanoparticles and methacryloyloxyethyl phosphoryl choline (MPC) polymer modifications of glass-ionomer cement, to inhibit demineralization around orthodontic bands.
Materials and Methods: 60 orthodontic patients with non-carious molars scheduled for banding were randomly divided into three groups. Grouping was based on (3% MPC, 3% nano-Titanium, and 3%+3% of both by weight) added to the luting glass-ionomer cement (GIC) Medicem, which was used for cementation of prefabricated micro-etched orthodontic bands. Demineralization was recorded by using DiagnoDent pen (KaVo, Biberach, Germany) device. Statistical evaluation was performed with one way ANOA test.
Results: Bands cemented with conventional GIC showed the highest bacterial scores in comparison to those cemented with MPC polymer and nano-titanium modified GICs. There was significant difference between teeth banded with 3% MPC, 3% nano-titanium, and 3% MPC + 3% nano-titanium modified GICs.
Conclusions: Modification of the banding GIC with MPC polymer and nano-titanium revealed a positive effect on reducing white spots around orthodontic bands.
