Aim: This study assessed the radiopacity of three bioceramic root repair cements (NeoMTA Plus®, Biodentine®, and MTA Angelus®) with two radiopacity tests: a traditional circular-disk method, using aluminium step wedges with the substitution of films for digital radiography (we called “ANSI/ADA-based test”) and a tissue-simulator method, using a cadaver model. Materials and Methods: Six circular specimens from each cement were fabricated to undertake the traditional ANSI/ADA-based radiopacity test; and six specimens from each cement were fabricated (into polyethylene tubes) to undertake the tissue simulator test. Data were compared intra-group and between the two radiopacity tests. Results: Radiopacity data was reported in greyscale pixels (from 0 to 255). Discussion: The tissue simulator method was able to show that Biodentine®, although being less radiopaque than NeoMTA Plus® and MTA Angelus®, had higher radiopacity than 3mm-Al (fact that did not occur with the traditional method). This finding is critical because it refutes some previous beliefs that Biodentine® is not radiopaque enough to be used as a root repair material. Conclusion: The tissue simulator radiographic test showed all the cements more radiopaque in comparison to the radiopacity produced by the traditional circular-disks test (ANSI/ADA-based) (p<0.05). Biodentine® presented more radiopaque than 3 mm-Al, only in the tissue simulator method (p<0.05). ; Objetivo: Este estudo avaliou a radiopacidade de três cimentos biocerâmicos para reparo radicular (NeoMTA Plus®, Biodentine® e MTA Angelus®) com dois testes de radiopacidade. Materiais e Métodos: Os dois testes de radiopacidade foram: um método tradicional de disco circular, usando placas de alumínio com substituição de filmes por radiografia digital (denominado “teste baseado em ANSI/ADA”) e um método simulador de tecido, usando um modelo de cadáver. Seis corpos de prova circulares de cada cimento foram fabricados para realizar o tradicional teste de radiopacidade baseado em ANSI/ADA; e seis ... |
