Adaptation of a resin composite in vivo.

OBJECTIVE: The adaptation of experimental dentine bonding systems has been evaluated in vivo. METHODS: A cylindrical cavity which extended into dentine was prepared in the facial surface of vital teeth that were to be extracted for orthodontic reasons. The preparations were restored with a commercial light-activated resin composite that was mediated by experimental dentine bonding systems. The restored teeth were extracted as soon as possible following polymerization of the composite. The marginal and internal adaptation of the resin composite restoration was observed under a light microscope in both horizontal and longitudinal sections of the teeth immediately after extraction. RESULTS: Of the experimental dentine bonding systems investigated, those including a primer of glyceryl methacrylate showed complete adaptation whereas those with primers of 2-HEMA showed a contraction gap in three out of 10 specimens.

Spectroscopic imaging by dephasing amplitude changing (SIDAC).

A technique for spectroscopic imaging based on a new concept of dual encoding (i.e., both phase and frequency encoding) of position along the direction of the read-out gradient is proposed. The phase encoding is produced by changing the amplitude of the dephasing gradient as in conventional phase encoding. High-resolution spectroscopic images of a normal human thigh obtained by a 2.0 Tesla whole body MR imaging system are presented.
