Comparative evaluation of postoperative sensitivity (POS) among three bulk fill restorative materials (Cention N, Equia Forte, Activa™ Bioactive restorative) in Class I posterior restorations.

Materials and Methods:

One hundred and forty-four patients having occlusal caries were arbitrarily selected and divided into three groups. Standardized Class I cavity was prepared and restored with Cention N, Equia forte, and Activa™ Bioactive restorative material. POS of restored tooth was assessed with a standardized cold test and air stimulus by air blow from the air syringe. Patient responses were assessed at an interval of 24 h, 1 week, and 1 month using a visual analog scale. Statistical analysis was performed using paired t-test, independent t-test, one-way ANOVA test, and Tukey's post hoc test using SPSS 11.0 program (SPSS Inc., Chicago, IL, USA) for windows.


The statistical analysis showed a significant difference in the clinical evaluation of POS at 24 h interval among three groups (Cention N, Activa™ Bioactive Restorative, Equia forte). However, following 1 week and 1 month, there is no significant difference in Group C (Activa™ Bioactive Restorative).


POS was seen more in Cention N contrast to Equia forte and Activa™ bioactive restorative material.
