Substance-P of neural cells in human trigeminal ganglion.

Expression of substance-P in human neurons of trigeminal ganglia has been investigated by immunohistochemistry and morphometry. These neurons constituted 12.8% to 32.6% of the total neuronal population in the trigeminal ganglia. Substance-P positive granulations were concentrated around the nucleus, distributed focally in neuroplasm or dispersed over the neuroplasm. Morphometric analysis has indicated the presence of three populations of SP-positive cells: small, medium-sized and large. The results suggest a functional differentiation on the level of the first neurons of the afferent path of the stomatognathic system. Substance-P is likely to play a role in the transmission not only of nociceptive impulses but also of those involved in the mechano-functional stimulation of system activities.

[Prosthetic treatment by fixed dentures as an aspect of dental caries prophylaxis and periodontal diseases]. / Leczenie protetyczne protezami stalymi w aspekcie profilaktyki próchnicy i chorob przyzebia.

The application of the new, more rational clinical and laboratory management methods of the fixed dentures performance in the Prosthetics Department in Gdansk is the aim of the paper. The methods and materials take dental caries prophylaxis and parodontium protection into consideration and they are based on: grinding limiting and application of partial crowns for installation instead of normal cost crowns; in the partial crowns there were used such composite materials as: Evicrol, Izopast, Izosit and others. Recently ABC preparation (Adhesive-Bridge-Cement) has also been used. The range of the partial crowns described application is various; they are applied not only in the anterior segments but also in the lateral parts of the dental arch. Wearing fixed dentures together with abiding by the hygienic regime is the common element of all modern, accurate and also careful for the dental tissues and noninvasive for the parodontium methods of treatment by fixed dentures.

[Selected cases of prosthetic treatment in patients with lowered height of the occlusion]. / Wybrane przypadki leczenia protetycznego pacjentów z obnizona wysokoscia zwarcia.

In the paper three selected cases that illustrate comprehensive prosthetic treatment in which modern methods and prosthetic materials have been used non-conventional composed bridges with partial crowns on abutment teeth sealed with composites in patients with deep bite are reported. For facing the crowns and bridges such materials as Izosit, porcelain, acryl-derived material--Colorstat which is superior to acrylate considering its physicochemical properties have been used. For the reconstruction of the patients, own teeth Izofil adhesive material has been used for capping the teeth partly or totally establishing a new occlusal situation in anterior and lateral segments.
