This document discusses the biocompatibility of dental materials and is presented by Dr. Ritu Gupta. It covers topics such as the CE marking which indicates European Conformity of dental materials. It also discusses nanoleakage at the composite-dentin interface and clinical testing of dental materials. References are provided on biocompatibility, allergic reactions to materials like nickel and latex, and investigating patient complaints related to oral galvanism through intraoral voltage measurements.

abbreviation of French phrase
"Conformité Européene" which
literally means "European
Conformity". The term initially
used was "EC Mark" and it was
officially replaced by "CE Marking"
in the Directive 93/68/EEC in 1993.

54. 2) Intraoral voltage
 Local electrical phenomena can occasionally
generate perceivable reactions in patients.
 This may be caused by short circuits, for
instance, if a new amalgam filling is placed in
direct proximal or occlusal contact with a high
gold alloy
 A number of measurement devices are
available on the market that can be used for
determining intraoral voltages between
different restorations.
