Abstract
Background: Success rate in composite restorations is associated with the degree of polymerization and light intensity.
Objectives: The aim of this study was to evaluate the light intensity of curing units in private offices in Qazvin 2003.
Methods: In this analytical study the light intensity of 62 light curing units were investigated before and after cleaning their light emitting tips using a radiometer. The results were classified in 3 groups as follows: A: sufficient intensity> 300 mw/cm2, B: borderline intensity (200-299 mw/cm2), and C: insufficient intensity
