Virtual restoration of fragmented glass plate photographs

Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004
In this paper we address the problem of restoration of fragmented glass plate photographs. We propose an algorithm based on the roto-translation of the fragments. A preprocessing adjustment in the contour combined with final interpolation is necessary to avoid artifacts.

Dental Caries under Glass Ionomer Restorations

Journal of Public Health Dentistry, 1996
AbstractThe Atraumatic Restorative Treatment (ART) technique has two potential limitations. Because only hand instruments are used, dental caries can be left during cavity preparation. Beyond this limitation, the glass ionomer filling material currently used has some unfavorable mechanical properties with respect to its strength, wear resistance, and ...
