Evaluation of effect of different disposable infection control barriers on light intensity of light-curing unit and microhardness of composite - An study.

Aims: This study evaluated effect of infection control barriers on light intensity (LI) of light-curing unit (LCU) and microhardness of composite.

Materials And Methods: Four different disposable barriers ( = 30) were tested against the control. LI for each barrier was measured with Lux meter.
