Abstract
Objective: To determine light intensity of light polimerization units used in the dental offices in Bucaramanga and its metropolitan area, and to evaluate the dentists’ knowledge in this subject.Methods: A descriptive cross section observational study was done. The universe was constituted by 283 and a sample of 110 dental offices was evaluated. The variables included were sociodemographical (municipality, socioeconomic status), about the light curing lamps (type of light, brand, maintenance, personnel performing the maintenance), about the lamp disinfestations (the substance that was used and frequency), and professional’s knowledge about the polimerization unit. Means, modes, medians and standard deviation were determined for all data. Bivariate analyses were performed by Fisher Exact Test and ANOVA.
Results: There were found statistically significant differences of the intensity of light with the variables of type of light with 59% (p<0.001), brand of the lamp without commercial reference with 65.4% (p=0.013), personnel performing maintenance, the technician with 61.8% (p=0.033), the substance used to disinfect, alcohol with 46.7% (p=0.0117), variables such as knowledge of the dentist 61% regular knowledge (p=0.012).
Conclusion: It was determined that 21.9% of the lamps didn’t have an appropriate intensity of light for curing the materials.
