Clinical Performance of Ion-Releasing Bulk-Fill Composites Quiz

Study on Clinical Performance of Ion-Releasing Bulk-Fill Composites

• A randomized clinical trial evaluated the 2-year clinical performance of two ion-releasing bulk-fill composites (Cention N and Surefil One) compared to a conventional bulk-fill resin composite (Powerfil) in Class I and II cavities.

Materials and Methods

• 32 patients with 3 Class I and/or Class II cavities under occlusion were enrolled in the trial, with a total of 96 restorations placed (32 for each material).
• The restorations were placed by a single operator and evaluated at baseline (1-week), 6-months, 1-year, and 2-years by two independent examiners using the FDI criteria.

Results

• 27 patients with a total of 81 restorations were evaluated at the end of the 2-years with 84.35% recall rates.
• Clinical success rates were 100%, 100%, and 96.3% for Powerfil, Surefil-one, and Cention N, respectively.
• Cention N showed a statistically significant (p < 0.05) decreased marginal integrity in comparison with resin composite at the 2-year evaluation.
• No recurrent decay was detected in any restoration.

Conclusion

• Both ion-releasing bulk-fill composites provided acceptable clinical performance similar to bulk-fill composite in Class I and II restorations over a 2-year period.
