Resumo: Purpose: This in vitro study used digital images to measure the radiopacity of the Portland cement (PC) containing or not radiopaque substances in relation to the radiopacity of the Mineral Trioxide Aggregate (MTA) cement. Methods: Three specimens were fabricated for each of the following five groups: 1) ProRoot MTA (Dentsply); 2) Portland cement – PC (Goiás); 3) PC + 2% uranyl acetate solution; 4) PC + 2% PTA solution; 5) PC + lead citrate solution. Specimens were stored in room temperature for 28 days and their radiopacity was measured by means of a direct digital radiography system (Sens-A-Ray), using the analytical functions line profile graph and histogram. Results: ProRoot MTA group showed the highest radiopacity; Portland cement radiopacity was approximately 60% of the MTA value. The tested solutions increased the radiopacity of Portland cement in the following rates: PTA=7%, uranyl acetate =12.5% and lead citrate =11%. Conclusion: The addition of radiopaque substances increased radiopacity of the original Portland cement, but it did not reach the level of ProRoot MTA radiopacity. Key words: Dental cements; MTA; Portland cement; radiopacity

Metodologia: Três espécimes foram preparados para cada um dos seguintes grupos: 1) ProRoot MTA (Dentsply); 2) cimento Portland – CP (Goiás); 3) CP + solução de acetato de uranila a 2%; 4) CP + de solução de PTA a 2%; 5) CP + solução de citrato de chumbo. Os espécimes foram armazenados por 28 dias em temperatura ambiente e a radiopacidade foi medida com um sistema de radiografia digital direta (Sens-A-Ray), usando as funções gráfico de perfil de linha e histograma. Resultados: O grupo ProRoot MTA apresentou a maior radiopacidade; a radiopacidade do cimento Portland foi aproximadamente 60% a do MTA. As soluções testadas aumentaram a radiopacidade do cimento Portland nas seguintes taxas: PTA=7%, acetato de uranila=12,5% e citrato de chumbo=11%. Conclusão: A adição de soluções radiopatizantes aumentou a radiopacidade padrão do cimento Portland, mas sem atingir o grau de radiopacidade do cimento ProRoot MTA.
