ABSTRACT

Calcium silicate cements have changed our methods of maintaining pulp integrity and health. These materials have evolved concurrently with our more conservative approach to pulp therapy, allowing caries to selectively remain and being minimally invasive. The speakers will blend a discussion of the bioactivity of the cements with a discussion of choosing an affordable, convenient and clinically effective product for multiple pulp therapy indications. Materials science analyses and ISO 6876 testing data will be presented on the compositions of the bioactive ceramics, physical characteristics (particle size and setting times) and costs per dose. Confusing distinctions among products will be clarified with pros and cons of various product formats.

Results of several randomized clinical trials using calcium silicate cements on primary teeth pulpotomy have demonstrated that these materials are equal or even better than the traditional formocresol. This fact, together with improved dispensing systems (decreasing waste and reducing costs) and better handling properties of some of these materials, may be suggested as an affordable and biologic substitute to formocresol in primary teeth pulpotomy.
