Guidance on the Determination of Potential Health Effects of Nanomaterials Used in Medical Devices -

This Guidance addresses the use of nanomaterials in medical devices and provides information for risk assessors regarding specific aspects that need to be considered in the safety evaluation of nanomaterials. According to the EU Recommendation for the definition of a nanomaterial (Commission Recommendation 2011/696/EU, EC 2011) any particulate substance with at least one dimension in the size range between 1 and 100 nm is considered a nanomaterial.

Estrogenicity and resin based dental materials -

Dental research has shown that small quantities of BPA and phthalates are eluted from resin-based materials and may be traced in saliva for a short period of time.

Health hazards associated with curing light in the dental clinic. -

The assessment of side effects of substances encountered in odontology by patients and the dental team must include the direct and indirect effects of irradiation emitted from polymerisation devices. The eyes of the lamp operators are at risk from acute and cumulative effects, mainly due to back-reflection of the blue light.

Dental workplace exposure and effect on fertility -

This study assessed occupational exposure in dental surgeries on the basis of the reported use of dental materials and techniques and applied waiting-time-to-pregnancy methodology to study fertility in relation to the occupational exposure.

Carbon fiber reinforced root canal posts: Mechanical and cytotoxic properties. -

The aim of this study was to compare the mechanical properties of a prefabricated root canal post made of carbon fiber reinforced composites (CFRC) with metal posts and to assess the cytotoxic effects elicited. Flexural modulus and ultimate flexural strength was determined by 3 point loading after CRFC posts had been stored either dry or in water.
