The use of photoactivation lamps is essential in dentistry to ensure the adhesion of light-activated
polymeric materials. The quality of light influences polymerization, a crucial step in dental treatments. Therefore, these lamps must provide the required properties for these materials. Inadequate light can negatively affect treatments. Objective: To evaluate the power and
irradiance of photoactivation lamps in the School of Dentistry at the University of America.
Problem: What is the power and irradiance produced by dental photoactivation lamps in the
clinical area of the School of Dentistry at the University of America?
Materials and Methods: The power (mW) and irradiance (mW/cm²) of thirteen lamps used in
the clinical area and two external control lamps were measured. Readings were obtained using
a digital radiometer, Bluephase® II Ivoclar, with the lamps placed on a stand and activated for
ten seconds. Results: It was found that seven lamps had irradiance exceeding 300 mW/cm² at a
distance of 0 mm, decreasing at greater distances. Twelve lamps recorded lower values than the
control lamps. Lamps older than five years exhibited lower power and irradiance than newer ones. Conclusion: Smaller-diameter lamps had higher irradiance than larger-diameter lamps. Only four lamps in the clinical area exhibited an acceptable condition in terms of permanent and reversible damage. This study underscores the importance of light quality in dentistry.
