Resumo: Purpose: To measure the optical density of the calcium hydroxide cavity liners Biocal (Biodynamics), Dycal (Dentsply), and Life (Kerr), and to compare them with the dentin optical density. Methods: Specimens were made with 1, 2, and 3mm- thickness and x-rayed using the Gendex 765 DC (Dentsply) equipment. The images were captured by using a direct digital system (Visualix, Gendex/Dentsply). Optical density was measured in gray tones using the software Image Tool for Windows 1.28. Data were analyzed by ANOVA and Tukey’s test (5% level of significance). Results: Life cement had the highest value (238.66 gray tones for 3 mm-thick) and Biocal cement showed the lowest value (78.66 gray tones for 1 mm-thick). In dentin the mean values were 48.67 grey tones for 1 mm-thick, 64.27 for 2 mm-thick, and 86.93 for 3 mmthick. Conclusion: All tested calcium hydroxide cavity liners showed higher optical density than dentin. Key words: Optical density; calcium hydroxide cavity liners; digital radiography

Metodologia: Corpos-de-prova foram confeccionados com espessuras de 1, 2 e 3 mm e radiografados com o aparelho Gendex 765 DC (Dentsply). Posteriormente as imagens foram capturadas pelo sistema de radiografia digital direta CCD (Visualix, Gendex/Dentsply). A densidade óptica em tons de cinza foi mensurada utilizando o programa Image Tool for Windows 1.28. Os dados foram analisados por ANOVA e teste de Tukey (nível de significânica de 5%). Resultados: O maior valor medido foi o do cimento Life com 238,66 tons de cinza na espessura de 3 mm e o menor valor foi o do Biocal com 78,66 tons de cinza para 1mm. Em dentina, obteve-se 48,67 tons de cinza para 1 mm de espessura, 64,27 para 2mm e 86,93 para 3mm. Conclusão: Todos os cimentos de hidróxido de cálcio testados apresentaram valores de densidade óptica superiores à da dentina.
