title: Radioactive tracer technique for monitoring of microleakage: an interim report.
abstract: A diffusion apparatus for the measurement and monitoring of microleakage is described. Radioactive ions are used to measure the diffusion across a section of a filled tooth. A study was made of the sealing ability of some amalgams and a composite resin filling material.
