Calcium silicate materials in endodontics

I refer to the article entitled ‘Calcium Silicate Materials in Endodontics’, published in the October issue of Dental Update, which I was interested to read. It contains a high level of detail regarding an exciting group of dental materials and demonstrates a close understanding of the subject. However, while the table on page 716 correctly indicates that these materials have been developed over time in various generations which indicate progress from one to the next, it concludes with the inclusion of filled resin-based material.

Whilst accepting an element of commercial bias, having invested heavily in the research and development which brought Biodentine to market, we at Septodont would strongly disagree with the inclusion of TheraCal LC which, as detailed on page 719, is resin-based and even contains bisphenol A (BPA). This seems so far from the entire philosophy of Biodentine and other calcium silicate-based cement material technologies that it is potentially confusing, even misleading, to your readership. We believe that this significant difference needs to be explained in order that any confusion is removed.
