Resumo: | Introduction: RDC No. 330 is the process for using a portable camera for processing intraoral radiographs, provided that it is made of opaque material and that it has a stopwatch and thermometer to perform radiographic processing using the time x temperature method. The aim of this study was to evaluate the filtration of light in portable cameras with viewfinder and without viewfinder and its influence on the veiling of periapical radiographic films. Methodology: This experimental study tested four portable darkrooms from brands NMartins.e Essence Dental VH with visor, Manoel PG all red acrylic and one without a visor by Delta Del Grandi. For control, a completely dark room was used. The periapical films used were from group E (Carestream and AGFA) and processed with developer and fixer solutions for three minutes in the developer, 20 seconds in the intermediate bath (water), six minutes in the fixer and 10 minutes in the final bath. After drying, such radiographs were digitized. The measurement of the pixel corresponding to the optical density of the darkest area was performed, obtaining a value between 0 (black) and 255 (white) in an 8-bit computer. Result: In the darkrooms ManoelPG and NMartins, the image of the coin was visible, demonstrating light veiling in both films. In the EssenceVH portable darkroom, there was total blurring, and it was not possible to visualize the contrast of the coin image, nor to measure the density. Conclusion: The darkroom without a viewfinder proved to be suitable for radiographic processing, however, as with viewfinder or fully acrylic, they did not filter out, causing the light to be blurred. |

El objetivo de este estudio fue evaluar la filtración de luz en cámaras portátiles con visor y sin visor y su influencia en el velo de películas radiográficas periapicales. Metodología: Este estudio experimental probó cuatro cuartos oscuros portátiles de las marcas NMartins.e Essence Dental VH con visor, Manoel PG todo acrílico rojo y uno sin visor de Delta Del Grandi. Para el control, se utilizó una habitación completamente oscura. Las películas periapicales utilizadas fueron del grupo E (Carestream y AGFA) y procesadas con soluciones de revelador y fijador durante tres minutos en el revelador, 20 segundos en el baño intermedio (agua), seis minutos en el fijador y 10 minutos en el baño final. Después del secado, estas radiografías se digitalizaron. Se realizó la medición del píxel correspondiente a la densidad óptica de la zona más oscura, obteniendo un valor entre 0 (negro) y 255 (blanco) en un ordenador de 8 bits. Resultado: En los cuartos oscuros ManoelPG y NMartins, la imagen de la moneda era visible, demostrando un velo de luz en ambas películas. En el cuarto oscuro portátil EssenceVH, hubo un desenfoque total, y no fue posible visualizar el contraste de la imagen de la moneda, ni medir la densidad. Conclusión: El cuarto oscuro sin visor demostró ser adecuado para el procesamiento radiográfico, sin embargo, al igual que con el visor o completamente acrílico, no se filtraron, lo que provocó que la luz se volviera borrosa.Introdução: a norma RDC nº 330 estabelece o uso de câmara escura portátil para o processamento de radiografias intrabucais, desde que seja confeccionada em material opaco e que tenha cronômetro e termômetro para a realização de processamento radiográfico pelo método temperatura x tempo. O objetivo desse estudo foi avaliar a filtração da luz em câmaras portáteis com visor e sem visor e sua influência no velamento dos filmes radiográficos periapicais. Metodologia: Este estudo experimental testou quatro câmaras escuras portáteis das marcas, NMartins.e Essence Dental VH com visor, Manoel PG toda de acrílico vermelho e uma sem visor da Delta Del Grandi. Para controle foi utilizado um quarto totalmente escuro. Os filmes periapicais utilizados foram do grupo E (Carestream e AGFA) e processados com soluções reveladora e fixadora por três minutos no revelador, 20 segundos no banho intermediário (água), seis minutos no fixador e 10 minutos no banho final. Após secas, as radiografias foram digitalizadas. Foi realizada a medida do pixel correspondente a densidade óptica da área mais escura, obtendo-se um valor entre 0 (preto) a 255 (branco) em um computador com 8bits. Resultado: Nas câmaras escuras ManoelPG e NMartins, a imagem da moeda foi visível, demonstrando velamento por luz em ambos os filmes. Na câmara escura portátil EssenceVH o velamento foi total, não sendo possível visualizar o contraste da imagem da moeda, nem mensurar a densidade. Conclusão: A câmara escura sem visor mostrou-se adequada para o processamento radiográfico, entretanto, as com visor ou totalmente acrílica não filtraram adequadamente a luz causando velamento.Research, Society and Development2021-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1846710.33448/rsd-v10i9.18467Research, Society and Development; Vol. 10 No. 9; e49910918467Research, Society and Development; Vol. 10 Núm. 9; e49910918467Research, Society and Development; v. 10 n. 9; e499109184672525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/18467/16398Copyright (c) 2021 Anderson Queiroz Galvão; Max Evandro Lima Carneiro ; Híttalo Carlos Rodrigues de Almeida; Zilda Betânia Barbosa Medeiros de Farias; Pâmella Recco Álvares; Márcia Maria Fonseca da Silveira; Ana Paula Veras Sobral; Cleomar Donizeth Rodrigueshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGalvão, Anderson QueirozCarneiro , Max Evandro Lima Almeida, Híttalo Carlos Rodrigues deFarias, Zilda Betânia Barbosa Medeiros deÁlvares, Pâmella Recco Silveira, Márcia Maria Fonseca daSobral, Ana Paula Veras Rodrigues, Cleomar Donizeth 2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/18467Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:36.073345Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
