Apesar dos resultados obtidos ao longo desta tese serem promissores, existem ainda aspetos que necessitam de ser estudados com mais atenção em trabalhos futuros. Encontradas as condições ideais conducentes à formação de C3A e C3S durante o tratamento térmico, será ainda necessário realizar um estudo detalhado e sistemático acerca do processamento dos pós, com vista à obtenção da distribuição granulométrica ideal. Deste modo, sugerem-se um conjunto de ações:
• Melhorar e otimizar o processo de moagem dos pós C3A e C3S;
• Efetuar um estudo sistemático acerca da distribuição de tamanho de partícula dos pós de partida, para identificar qual a ideal e otimizar o processo para que seja reprodutível;
• Formular novas composições de cimentos biocerâmicos, de forma a que os cimentos biocerâmicos contenham na sua composição agentes aceleradores;
• Efetuar estudos in vitro em fibroblastos de forma a avaliar a biocompatibilidade, a viabilidade da resposta pulpar e a infiltração; • Realizar estudos de cinética de hidratação usando técnicas de calorimetria
e de difração de raios-X in situ em colaboração com outros laboratórios que disponham destas facilidades.
