Resumo: | The purpose of this article was to compare the mean value of optical density of four porcelains commonly used for fabrication of inlay/onlay prostheses using direct digital radiograph. The sample consisted of 20 2-mm thick porcelain specimens (measured by digital pachymeter): Empress (Ivoclair), Simbios (Degussa), Vita Omega 900 and Vitadur Alpha (Vita Zahnfabrik). The values of optical density of the specimens were expressed in millimeters aluminum equivalent (mm eq Al). The samples were X-rayed using two charge coupled devices (CCD) - RVG (Trophy) - Visualix (Gendex) and a phosphor plate system - Digora (Soredex). The optical density reading was performed with Image Tool 1.28 in a total of 110 measurements. Statistical analysis showed that there were statistically significant differences in all materials studied (p < 0.05) regardless of the radiographic system used. The highest optical density value was found for Omega 900 (1.8988 mmeqAl - Visualix - Gendex) and the lowest for Vitadur Alpha (0.8647 - Visualix - Gendex). Thus, the material presenting the highest degree of optical density was Omega 900, Empress and Simbios presented intermediate optical density values, Vitadur Alpha presented the lowest value, and the optical density of porcelains was not influenced by the digital radiography systems. |

Objetivo desse trabalho é comparar valores médios de densidade óptica de quatro porcelanas comumente utilizadas para confecção de inlay/onlay por meio da densidade óptica usando radiografia digital. A amostra constou de 20 corpos de prova com espessura de 2mm (mensurados em paquímetro digital) das porcelanas: Empress (Ivoclair), Simbios (Degussa), Vita Omega 900 e Vitadur Alpha (Vita Zahnfabrik). Os valores de densidade óptica das amostras foram expressos em milímetros equivalente em alumínio (mm eq Al). Os espécimes foram radiografados, utilizando dois sistemas de dispositivo de carga acoplada (CCD) - RVG (Trophy) - Visualix (Gendex) e um sistema de placa de fósforo - Digora (Soredex). A leitura da densidade óptica foi realizada no programa Image Tool 1.28 totalizando 110 medições. As leituras de densidade ópticas foram feitas no programa Image Tool 1.28 totalizando 110 mensurações. A análise estatística demonstrou que houve diferença estatisticamente significante entre a densidade óptica das porcelanas estudadas independentemente do sistema de radiografia empregado (p < 0,05). A porcelana Omega 900 obteve 1,8988mmeqAl - Visualix - Gendex e Vitadur Alpha 0,8647mmeqAl - Visualix - Gendex. Conclui-se que a porcelana Omega 900 apresentou os maiores valores de densidade óptica, enquanto que Empress e Simbios obtiveram valores intermiediários, Vitadur Alpha apresentou os menores valores de densidade óptica e a densidade óptica das porcelanas não foram influenciadas pelo sistema de radiografia digital.
