Evaluación de la intensidad lumínica generada por lámparas de fotopolimerización utilizadas en consultorios privados de la ciudad de Cuenca. 2018

Abstract

The luminous intensity is important for the activation of photosensitive biomaterials and its minimum value is 400mW/cm2. The most common lamps are Halogen and LED. The presence of fractures or residues of biomaterials on their optical fiber can affect their light intensity.

MATERIALS AND METHODS: The sample was 366 units, the type of lamp, trademark, model, presence or absence of fractures and residues of biomaterials on optical fiber was determined. The dental radiometer Bluephase Meter II, determined the diameter of the fiber and the light intensity. The data obtained was analyzed with the IBM SPSS Stadistics version 23 program.

RESULTS: 67.2% had adequate intensity and 32.8% inadequate. In addition, 19.1% were halogen lamps and 80.9% LED. In contrast, 64.7% of units had optical fiber with a diameter of 8 mm; 15.6% of 9 mm; 12% of 10 mm; 2.2% of 11mm and 5.5% of 12mm. In addition, 78.7% did not have fiber optic fractures, but 21.3% did. Finally, 55.5% had residues of dental biomaterials on the optical fiber and 44.5% were free of them.

CONCLUSIONS:

32.8% of devices had intensities lower than 400 mW / cm2, with a higher percentage of halogen lamps than LEDs. The optical fibers with diameters of 8 and 9 mm, represented the highest percentages. The light intensity can be affected by the presence of fractures or residues of dental biomaterials on the optical fiber
