To assess depth of cure and hardness of bulk-fill composites

AUTHOR(S): Pinky Singh and Sanjay Kumar Singh

ABSTRACT:Background: The increased usage of direct chair-side application of resin composite for restoring cavities in the anterior and posterior dentition has continued despite their technique sensitivity and limited depth of cure. The present study was conducted to assess depth of cure and hardness of bulk-fill composites.

Materials & Methods: The present in vitro study was conducted in department of Endodontics. It comprised of 3 RBC material-Tetric N-Ceram bulk fill (TNCBF), Tetric Evoflow bulk fill (TEFBF) and Surefil SDR bulk-fill (SDRBF). Hardness of materials was estimated in all materials.

Results: Materials used in the study was Tetric N-Ceram bulk fill (TNCBF), Tetric Evoflow bulk fill (TEFBF) and Surefil SDR bulk-fill (SDRBF) were placed in group I, II and III respectively. The mean hardness value of group I material at top was 45.2 and at bottom was 32.5, in group II at top was 41.0 and at bottom was 33.6, in group III at top was 38.2 and at bottom was 34.1. The difference was significant (P< 0.05).

Conclusion: Authors found that hardness value of Tetric N-Ceram bulk fill material was highest among all restorative materials.
