30-Month randomised clinical trial to evaluate the clinical performance of a nanofill and a nanohybrid composite
Objective To evaluate the clinical performance of a nanofill and a nanohybrid composite in restorations in occlusal cavities of posterior teeth in a randomised trial over 30 months. Methods Forty-one adolescents participated in the study. The teeth were restored with a nanofill (Filtek Z350, 3M E...

Objective
To evaluate the clinical performance of a nanofill and a nanohybrid composite in restorations in occlusal cavities of posterior teeth in a randomised trial over 30 months.
Methods
Forty-one adolescents participated in the study. The teeth were restored with a nanofill (Filtek Z350, 3M ESPE), a nanohybrid (Esthet-X, Dentsply); Filtek Z250 (3M ESPE) was used as a control. After 30 months, the restorations were evaluated in accordance with the US Public Health Service (USPHS) modified criteria. The McNemar and Friedman tests were used for statistical analysis, at a level of significance of 5%.
Results
There were significant differences in the roughness of Filtek Z250 (p = 0.008) and Filtek Z350 (p < 0.001) when the four time periods (baseline, 6 months, 12 months and 30 months) were compared. There were significant differences in the marginal adaptation of Filtek Z250 (p = 0.001), Filtek Z350 (p < 0.001) and Esthet-X (p = 0.011). Except for one of each composite restoration, all the modifications ranged from Alpha to Bravo. There were significant differences in the surface roughness (p = 0.005) when the three composites were compared after 30 months.
Conclusions
The materials investigated showed acceptable clinical performance after 30 months. Long-term re-evaluations are necessary for a more detailed analysis of these composites (CEP: #1252). |
