Dear Friends and Colleagues,
We would like to take this opportunity to invite you to the 4th World Conference on Glass Ionomer Cements, with the theme “Towards Biomimetic Dentistry”.
Paradigm of modern dentistry is to heal dental tissues. This includes healing destroyed tissues via biomimetic procedures such as remineralisation, restoration with bioactive materials and revascularisation of pulp tissues.
Since our last conference in London in 2015 we have witnessed a growing interest in Biomimetic Dentistry. The upcoming conference in 2018 in the beautiful city of Dubrovnik, brings together some of the renowned speakers in the area of Biomimetic Dentistry to highlight recent advances in the field. This will provide conference delegates an exciting opportunity to embrace Biomimetic Dentistry.
We look forward to seeing you at the conference.

Bisphenol A (BPA) is an endocrine disruptor with potential toxicity. Composite resins may not contain pure BPA, but its derivatives
are widely used. Several studies found doses of BPA or its derivatives in saliva or urine of patients after composite resin placement.
The aims of this study were to establish an exhaustive list of composite resins marketed in Europe and their composition, and to
assess the extent of BPA derivatives used.
A research on manufacturers’ websites was performed to reference all composite resins marketed in Europe, then their composition
was determined from both material safety data sheets and a standardized questionnaire sent to manufacturers. Manufacturers had to
indicate whether their product contained the monomers listed, add other monomers if necessary, or indicate “not disclosed”.
160 composite resins were identified from 31 manufacturers and 23 manufacturers (74.2%) responded to the survey. From the survey
and websites, the composition of 130 composite resins (81.2%) was: 112 (86.2%) based on BPA derivatives, 97 (74.7%) on bis-
GMA, 17 (13.1%) without monomer derived from BPA (UDMA, sometimes with TEGDMA) and 6 (4.6%) with UDMA (only); 1
(0.8%) did not contain a BPA derivative or UDMA or TEGDMA. Pure BPA was never reported.
This work has established a list of 18 composite resins that contain no BPA derivative. Manufacturers should be required to report
the exact composition of their products as it often remains unclear or incomplete.
