[Plaque-accumulation on galvano-ceramic crowns].

48 patients treated with galvano-ceramic crowns and bridges were evaluated as to their plaque indices according to Silness and Löe (PI) and their papillary bleeding indices (PBI) according to Mühlemann. The mean values of PI and PBI were determined for all teeth as well as for defined groups of teeth: sound teeth, teeth with galvano-ceramic crowns and other restorative materials. Galvano-ceramic crowns showed the least plaque accumulation. Their PI was lower than the PI of sound teeth. Resin-veneered crowns and full cast crowns exhibited significantly higher PI-values in the posterior area. Crowned teeth had a higher PBI than sound teeth, but galvano-ceramic crowns showed lower PBI-values than crowns of other restorative materials.

[Phonognathography in TMJ diagnosis].

A pilot study examined the frequency spectrum of TMJ-sounds, in particular clicking. A profound difference was observed between articular movement noises and clinical clicking. The frequency spectrum of normal movements is clearly different from the one observed for clicking. Therefore phonognathography might be an additional diagnostic tool to elucidate the reasons for individual clicking phenomena with Fourier analysis.
