Resumen
Objetivos: Evaluar la intensidad de fotocurado de lámparas de fotopolimerización
utilizadas en centros de salud familiar (CESFAM) de la región Metropolitana, durante el
año 2015. Método: Se revisaron 21 CESFAM, donde se midieron 97 lámparas con un
radiómetro certificado. Asimismo se realizó una encuesta de dos preguntas dirigida al
operador. Resultados: De una muestra de 97 lámparas, un 78% son LED. Del total de
la muestra, un 6% arrojó lámparas con emisiones menores a 300mW/cm2, 25% entre
300-<500mW/cm2, 36% entre 500-<800mW/cm2 y un 33% a potencias mayores a
800mW/cm2. Un 74% de los odontólogos utiliza 20 segundos para el fotocurado del
material. El 39% de las lámparas son utilizadas de forma adecuada, en la conjugación
de potencia versus tiempo. Un 3% de ellas tiene mantención.
Conclusión: Se registra una variabilidad de potencias, donde más del 50% de las
lámparas usadas en los CESFAM no genera la cantidad de polimerización adecuada
utilizando 20 segundos de fotocurado. Nuevos estudios serán necesarios para definir
qué factores causan deterioro en la potencia de luz en el tiempo.
Objectives: The following study show the current state of curing units used in family health centers (CESFAM) of the Metropolitan Region (Chile) during the year 2015. Method: 97 units were measured with a cure certificate radiometer in 21 CESFAM. Beside visual observation and two-question questionnaire was made. Results: 78% of the light are LED. 6% of the sample, corresponds to lamps with lower emissions to 300mW / cm2, 25% between 300- <500mW / cm2, 36% between 500- < 800mW / cm2 and 33% to higher powers to 800mW / cm2. 74% of dentists use 20 seconds to cure the material, it was found that 39% of lamps are efficient in the conjugation of power versus time. Only 3% of them have maintenance. Conclusions: The results obtained show a variability of powers, in which more than 50 % of the lamps used in CESFAM do not generate the appropriate amount of polymerization for 20 seconds of curing. Further studies are needed to define which factors cause deterioration in light output over time.
